Background: Prolonged use of computers and mobile devices has contributed to postural abnormalities such as Rounded Shoulder Posture (RSP), which is characterized by muscle imbalances that can lead to pain and functional limitations. Correcting these imbalances through targeted stretching and strengthening exercises was expected to help improve postural alignment and muscle function. Objectives: This study aimed to investigate the effects of a six-week integrated exercise program targeting the pectoralis minor (PM), upper trapezius (UT), and lower trapezius (LT) on postural alignment and muscle activation in female adults with RSP. Design: Single-group pre-post test study. Methods: Eighteen female university students (aged 20–22 years) with RSP participated in a six-week intervention consisting of PM stretching, UT stretching, and LT strengthening exercises. RSP severity was assessed using acromion-to-ground distance, PM length was measured with a caliper, and surface electromyography (sEMG) was used to evaluate UT and LT muscle activity. Normality was verified using the Shapiro-Wilk test, and paired t-tests were conducted for statistical analysis (α=0.05). Results: After the intervention, significant improvements were observed in all measured variables. Acromion-to-ground distance decreased (P<0.001), PM length increased (P<0.001), UT activation decreased (P<0.01), and LT activation increased (P<0.01). Conclusion: The six-week integrated exercise program effectively improved postural alignment and muscle activation in women with RSP by addressing muscle shortening, overactivity, and weakness. These findings suggest that combined stretching and strengthening exercises can serve as a practical and effective approach for RSP correction. Future studies with longer durations and diverse populations are recommended to further validate these results and enhance clinical applicability.

이 연구에서는 김정은 시대 북한의 핵 관련 법에 나타난 핵전략과 핵 태세를 분석하였다. 북한은 미국의 대북 적대시 정책에 대한 대응으로 핵을 개발하였다고 주장하였으나, 김정은 시대 북한은 핵 관련 법을 제 정하고 핵을 무기화하였으며 핵능력을 고도화하였으며 당 제8차 대회 이 후에는 전술핵능력까지 구비하였다. 연구를 통해 북한이 핵을 군사적으 로 사용할 능력을 구비하고 고도화하면서 핵전략과 핵태세가 공세적으로 변화하였음을 확인할 수 있었다. 북한의 핵능력이 고도화되면서 핵전략 은 선언적 수준의 최소억지전략에서 대남 제한억지전략과 대미 최소억지 전략으로 발전하였고, 핵태세 또한 현재는 가장 공세적인 비대칭확장태 세 유형을 보여주고 있다. 북한의 핵·미사일 능력 고도화는 계속될 것이 다. 북한의 핵능력증가에 따른 대응 방안 마련이 제한되는 우리로서는 궁극적으로 북한의 핵 위협이 증가하지 않도록 하는 것이 중요하다.

Background: The increasing demand for real-time professional fitness coaching has led to a need for accurate exercise posture recognition using artificial intelligence.

The Stacked LSTM model demonstrated superior performance with a training error of 1.05% and test error of 6.09%. Conclusion: Both FNN and Stacked LSTM models effectively classified sequential fitness images, with Stacked LSTM showing superior performance. This indicates the potential of Stacked LSTM models for accurate fitness posture classification in real-time coaching scenarios.

Background: Artificial intelligence (AI) research on physical fitness posture estimation has been limited by a lack of comprehensive datasets and guidelines. This study analyzes the fitness image dataset provided by Korea's AIHub platform to advance posture estimation algorithms from exercise prescription and behavioral analysis perspectives. Objectives: To analyze fitness movements and guide correct exercise posture using AI-based visual and auditory feedback. Design: Descriptive analysis of a large-scale dataset. Methods: The study examined image and JSON labeling files from AI-Hub, analyzing 6.39 million fitness images across 41 exercise types. Data structure, exercise states, and annotation characteristics were analyzed in detail. Results: The dataset encompasses 816 distinct exercise states, captured from five camera angles with 24 key body points labeled per posture. Exercises were categorized into full-body workouts (17), barbell/dumbbell exercises (16), and furniture exercises (8). Gender distribution was 76% male and 24% female, with 41% in the 27-29 age group. The dataset allows for detailed analysis of correct and incorrect postures. Conclusion: This comprehensive analysis of the AI-Hub fitness dataset provides a robust foundation for developing AI models for fitness posture evaluation and feedback, benefiting exercise coach web/app service developers.

Background: The increasing prevalence of smartphone use has been associated with musculoskeletal pain; however, the specific roles of demographic factors, smartphone usage time, posture, contents and state of addiction on pain in the upper-body regions remain unclear. Objects: This study investigated the influence of smartphone usage characteristics, including age, occupation, visual condition, duration, content, and posture, as well as smartphone addiction, on musculoskeletal pain in upper-body regions. This study aimed to comprehensively elucidate the factors contributing to the pain associated with smartphone use. Methods: A cross-sectional survey was conducted with 316 participants aged 20–59 years. Data on personal characteristics, smartphone use patterns, state of addiction (measured using the Smartphone Addiction Scale-Short Version), and musculoskeletal discomfort (Cornell Musculoskeletal Discomfort Questionnaire and Cornell Hand Discomfort Questionnaire) were collected. Binary logistic regression analysis identified significant predictors of pain in different body regions. Results: Younger age (20–30 years), being housewives or students, and vision impairment (shortsightedness) significantly increased the likelihood of neck, shoulder, and hand pain. Prolonged smartphone use (7–10 hours daily) and gaming were strongly associated with elevated pain risk, whereas moderate usage (1–4 hours daily) may be protect against lumbar pain. Non-neutral postures, especially side lying, have emerged as critical risk factors, with left-side lying linked to hand pain and right-side lying linked to upper back pain. Smartphone addiction consistently predicted pain across all regions by amplifying physical strain through prolonged engagement and poor posture. Conclusion: This study highlighted the multifactorial nature of smartphone-related musculoskeletal pain, emphasizing the roles of demographic characteristics, usage patterns, and addiction. These findings provide a foundation for developing tailored ergonomic and behavioral interventions to mitigate pain risks, particularly in high-use populations. Future research should validate these findings through longitudinal studies and objective measures.

Background: For instance, forward head posture (FHP), characterized by the forward movement of the head relative to the spine, places significant stress on the neck and upper back muscles, disrupting the biomechanical balance of the body. Objects: The objective of this study was to probe the biomechanical effects of FHP on musculoskeletal health through a relative analysis of 26 adults diagnosed with FHP and 26 healthy controls. Methods: In this study, we evaluated the biomechanical impacts of FHP. Participants adjusted their head positions and underwent muscle strength tests, including electromyography assessments and the Biering-Sørensen test for trunk muscle endurance. Data analysis was conducted using Kinovea (Kinovea) and IBM SPSS software ver. 26.0 (IBM Co.) to compare muscle activities between groups with normal and FHPs. Results: The study shows that individuals with FHP have significantly lower muscle activity, endurance, and spinal extension in the erector spinae compared to those without, highlighting the detrimental effects of FHP on these muscles. Conclusion: This study underscores the impact of FHP on erector spinae function and emphasizes the need for posture correction to enhance musculoskeletal health and guide future research on intervention strategies.

Forward Head Posture (FHP) involves the anterior positioning of the head relative to the shoulders, often associated with muscular imbalances. It is known that individuals with FHP experience shortening of craniocervical extensors and cervical flexors. However, contrary to the understanding of flexion in the craniocervical extension subaxial region, a study has reported flexion in the craniovertebral spinal vertebrae among individuals with FHP. The aim of this study was to examine the consistency of biomechanical study results conducted for FHP. The relevant studies were investigated in PubMed and Google Scholar databases using the keywords “forward head posture OR cervical sagittal alignment OR cervical spine AND biomechanics OR kinetic analysis OR kinematic analysis.” During the research selection process, only nine studies relevant to the purpose of our study were identified. Out of these nine studies, four conducted kinematic analysis related to FHP formation, while six conducted kinetic analysis. During the comparison of these studies, five inconsistencies were identified. Biomechanical studies on FHP reveal conflicting findings, suggesting potential variability in the biomechanics of FHP formation across individuals. However, drawing definitive conclusions requires further exploration through additional biomechanical investigations on FHP in the future.

Background: Child care center teachers are exposed to musculoskeletal injuries caused by repetitive movements at low heights due to the nature of their jobs. Self-myofascial release (SMFR) improves flexibility, pain, and functional performance. Pectoralis minor self-stretching (PMSS) improves muscle flexibility and postural alignment. PMSS has been commonly used to correct a rounded shoulder posture (RSP). Objectives: To examine the shoulder height, muscle tone, muscle stiffness, and muscle elasticity for women child care center teachers with RSP. Design: Randomized study. Methods: The participants were 20 women child care center teachers with RSP. They were randomly assigned two groups: SMFR group (n=10) and PMSS group (n=10). They performed each exercise for 20 min, 3 times a week for 4 weeks. They measured shoulder height, muscle tone, stiffness, and elasticity of upper trapezius before and after exercise. Results: In the shoulder height, there was no significant difference between two groups. There were significant decreases within both groups. In the muscle tone, stiffness, and elasticity, there was no significant difference between two groups and within two groups. Conclusion: SMFR using a hard massage ball and PMSS have a positive effect on posture correction for child care center teacher with RSP.

Background: Forward head posture affects many individuals and can cause pain and dysfunction in the muscles and joints of the head, neck, and shoulders. Objectives: This study aimed to assess muscle activity and onset time of cervical and scapular muscles during 180° shoulder flexion and abduction in individuals with normal head posture (NHP) and in those with forward head posture (FHP), both before and after correction. Design: Cross-sectional study. Methods: Thirty-six individuals were divided into FHP and NHP groups. Muscle activity and muscle contraction onset time of the splenius capitis, sternocleidomastoid, upper middle and lower trapezius, and serratus anterior muscles were measured during shoulder flexion and abduction using wireless surface electromyography. Results: The FHP group exhibited increased muscle activity compared to the NHP group (P<.05), notably in the sternocleidomastoid and middle trapezius muscles, more so during shoulder abduction than flexion (P<.05). Regarding muscle contraction onset time, sternocleidomastoid onset was fastest during shoulder abduction in the FHP group (P<.05), while serratus anterior onset was slowest during both shoulder abduction and flexion (P<.05). Conclusion: These findings highlight distinct muscle activity and muscle contraction onset time patterns based on head posture and shoulder movement. Selective muscle activation strategies may help reduce heightened sternocleidomastoid and trapezius activity and enhance serratus anterior engagement in individuals with FHP.

거북목 자세는 현대인의 대표적인 자세 변형 문제로 신체적 및 정신적으로 다양한 문제를 야기하고 있으나 거북목 자세가 휴식시 불편함이나 주의력 분산 등에 미치는 영향은 잘 알려지지 않았다. 이에 본 연구에서는 휴식시의 뇌파 신호 분석을 통하여 거북목 자세가 뇌기능에 미치는 영향을 확인하고자 한다. 본 연구에는 33명의 컴퓨터 과사용자가 참여하였고 그들은 모두 컴퓨터 사용시 기능적 거북목 자세가 나타났다. 연구참여자는 정상자세와 거북목 자세를 번갈 아 수행하도록 하였고, 각 자세를 5분 동안 유지하는 동안 자극이 주어지지 않은 상태로 휴식시 뇌파를 측정하였다. 뇌파 는 32개의 채널에서 신호를 획득하였고, 주파수 분석을 통해 불편함이나 주의력에 밀접한 관련이 있다고 알려져 있는 델타파와 베타파에 대한 자세별 변화를 비교 분석하였다. 그 결과 거북목 자세에서는 정상자세 보다 9개의 채널에서 델타파의 유의한 감소를 보였고, 14개의 채널에서는 베타파의 유의한 증가를 보여주면서 거북목 자세가 휴식시 뇌기능에 영향을 주는 것으로 나타났다. 이러한 변화는 심리적 불편감과 주의력 분산 상태에서 나타나는 변화와 일치하며 거북 목 자세의 근골격계 변화로 인해 증가된 불편함이 뇌활성에도 영향을 주기 때문으로 보인다. 이러한 결과는 자세 교정이 이루어진다면 휴식시 뇌기능과 심리 상태 개선에 도움이 될 수 있다는 것을 보여주는 중요한 결과로 평가될 수 있다.

Background: The forward head posture acts as a factor that can cause various neurovascular and musculoskeletal dysfunctions. But searching for a study on quality of life for patient with forward head posture was challenging. Therefore, this study aims to find the factors that most affect the quality of life in patients with forward head posture. Objectives: The purpose of this study was to investigate the correlations between the cranio-vertebral angle (CVA), neck disability index (NDI), pain, and sternocleidomastoid (SCM) thickness of patients with forward head posture and the quality of life of the patients and to figure out important factors that affect the quality of life of the patients with forward head posture. Design: Cress-sectional study. Methods: To measure the CVA, the angle at which the visible protrusion of C7 and the ear bead were connected was measured, and the neck disorder index was evaluated using the Korean version of NDI. The degree of pain of the subject was measured using a visual-analog scale (VAS). The SCM thickness was measured using an ultrasound imaging device, and the quality of life was evaluated using the Korean version of the World Health Organization quality of life questionnaire (WHOQL-BREF). Results: A significant predictive model showing 88% explanatory power for the dependent variable was confirmed, with an appropriate regression equation being found. The factor that most affected patients' quality of life in the forward head posture was confirmed by the SCM thickness. Conclusion: When applying an intervention to improve a patient's quality of life for patient with forward head posture, an intervention method that improves the SCM thickness should be recommended.

Background: There is a lack of research on sling neurac exercise interventions for craniovertebral angle (CVA), head rotation angle, range of motion (ROM), and neck postural alignment in adults with forward head posture Objectives: To investigate the Immediate effects of sling neurac exercise on craniosacral angulation, ROM, and neck postural alignment in adults with forward head posture. Design: Quaxi-experimental study. Methods: Fifty young adults in their 20s were divided into a sling neurac exercise group (SNEG) and a control group (CG). SNEG conducted sling neurac exercise intervention for one day, and CG did not implement intervention. Craniosacral angulation, ROM, and postural alignment before and after exercise was evaluated for each group. Results: In the sling neurac exercise group (SNEG), CVA, cranial rotation angle (CRA), ROM, and postural alignment improved significantly after intervention (all P<.01). There were no significant differences in the control group (CG) (all P>.05). After the intervention, there were significant differences between the groups in craniosacral angulation, ROM, and postural alignment (all P<.01). Conclusion: The Sling neurac exercise can significantly improve CVA, CRA, ROM, and postural alignment. Therefore, it is suggested to consider sling neurac exercise as an intervention.

Forward head posture (FHP) is a musculoskeletal disorder that causes neck pain. Several exercise interventions have been used in South Korea to improve craniovertebral angle (CVA) and relieve neck pain. There has been no domestic literature review study over the past 5 years that has investigated trends and effects of exercise intervention methods for CVA with neck pain. This domestic literature review aimed to evaluate the trends and effects of exercise interventions on CVA and neck pain in persons with FHP. A review of domestic literature published in Korean or English language between 2018 and 2022 was performed. Literature search was conducted on Google Scholar and Korea Citation Index by using the following keywords: “exercise,” “exercise therapy,” “exercise program,” “forward head posture,” and “neck pain.” Ten studies were included in this review. All of the studies showed positive improvements after intervention programs that included exercises. Notably, four of these studies demonstrated significant differences in results between the experimental and control groups. Among the 10 studies, nine measured visual analogue scale or numerical rating scale scores and reported significant reductions in pain following interventions, including exercise programs. Five of these studies showed significant differences in results between the experimental and control groups. Furthermore, six studies that used neck disability index exhibited a significant decrease in symptoms after implementing intervention programs that included exercise, and significant differences in results were found between the experimental and control groups. This domestic literature review provides consistent evidence to support the application of various exercise intervention programs to improve CVA and relieve neck pain from FHP. Further studies are warranted to review the effects of various exercise interventions on FHP reported not only in domestic but also in international literature.

Background: In modern society, the use of computers accounts for a large proportion of our daily lives. Although substantial research is being actively conducted on musculoskeletal diseases resulting from computer use, there has been a recent surge in interest in improving the working environment for prevention. Objects: This study aimed to examine the effects of posture correction feedback (PCF) on changes in neck posture and muscle activation during computer typing. Methods: The participants performed a computer typing task in two sessions, each lasting 16 minutes. The participant’s dominant side was photographed and analyzed using ImageJ software to verify neck posture. Surface electromyography (EMG) was used to confirm the participant’s cervical erector spinae (CES) and upper trapezius muscle activities. The EMG signal was analyzed using the percentage of reference voluntary contraction and amplitude probability distribution function (APDF). In the second session, visual and auditory feedback for posture correction was provided if the neck was flexed by more than 15° in the initial position during computer typing. A 20-minute rest period was provided between the two sessions. Results: The neck angle (p = 0.014), CES muscle activity (p = 0.008), and APDF (p = 0.015) showed significant differences depending on the presence of the PCF. Furthermore, significant differences were observed regarding the CES muscle activity (p = 0.001) and APDF (p = 0.002) over time. Conclusion: Our study showed that the feedback system can correct poor posture and reduces unnecessary muscle activation during computer work. The improved neck posture and reduced CES muscle activity observed in this study suggest that neck pain can be prevented. Based on these results, we suggest that the PCF system can be used to prevent neck pain.

Background: Studies investigating the immediate effects of a single intervention to correct forward head posture are rare. Objects: This study aimed to compare the changes in treatment effects in patients with forward head posture and neck pain after manual and self-exercise therapy over a 1-hour period. Methods: Twenty-eight participants were randomly divided into manual and self-exercise therapy groups. Following the initial evaluation, manual or self-exercise therapy was applied to each group for 30 minutes each in the prone, supine, and sitting positions. The variables measured were the craniovertebral angle (CVA), stress level, pain level, and sternocleidomastoid (SCM) stiffness. After the intervention, re-evaluation was conducted immediately, 30 minutes later, and 1 hour later. Two-way analysis of variance (ANOVA) was used to compare the maintenance of treatment effects between the two groups. Results: Based on the two-way mixed ANOVA variance, there was no interaction between the groups and time for all variables, and no main effects were found between the groups. However, a significant effect of time was observed (p < 0.05). Post hoc tests using Bonferroni's correction revealed that in both groups, the CVA, pain, and stress showed significant improvements immediately after the intervention compared with before the intervention, and these treatment effects were maintained for up to 1 hour after the treatment (p < 0.0083) in the manual therapy group. However, the stress level was maintained until 30 minutes later (p < 0.0083) in the self-exercise group. There was no significant decrease in right SCM stiffness before and after the intervention; however, left SCM stiffness significantly decreased after the self-exercise intervention (p < 0.0083). Conclusion: Both manual and self-exercise therapy for 30 minutes were effective in reducing forward head posture related to the CVA, pain, and stress levels. These effects persisted for at least 30 minutes.

Background: Office workers experience neck or back pain due to poor posture, such as flexed head and forward head posture, during long-term sedentary work. Posture correction is used to reduce pain caused by poor posture and ensures proper alignment of the body. Several assistive devices have been developed to assist in maintaining an ideal posture; however, there are limitations in practical use due to vast size, unproven long-term effects or inconsistency of maintaining posture alignment. We developed a headphone and necklace posture correction system (HANPCS) for posture correction using an inertial measurement unit (IMU) sensor that provides visual or auditory feedback. Objects: To demonstrate the test-retest reliability and concurrent validity of neck and upper trunk flexion measurements using a HANPCS, compared with a three-dimensional motion analysis system (3DMAS). Methods: Twenty-nine participants were included in this study. The HANPCS was applied to each participant. The angle for each action was measured simultaneously using the HANPCS and 3DMAS. The data were analyzed using the intraclass correlation coefficient (ICC) = [3,3] with 95% confidence intervals (CIs). Results: The angular measurements of the HANPCS for neck and upper trunk flexions showed high intra- (ICC = 0.954–0.971) and inter-day (ICC = 0.865–0.937) values, standard error of measurement (SEM) values (1.05°–2.04°), and minimal detectable change (MDC) values (2.92°–5.65°). Also, the angular measurements between the HANPCS and 3DMAS had excellent ICC values (> 0.90) for all sessions, which indicates high concurrent validity. Conclusion: Our study demonstrates that the HANPCS is as accurate in measuring angle as the gold standard, 3DMAS. Therefore, the HANPCS is reliable and valid because of its angular measurement reliability and validity.

The DPRK had been upgrading its nuclear weapons capabilities from the past to the sixth nuclear test in 2017, and Kim Jong-un has been in power since the death of Kim Jong-il in 2011, striving to upgrade and diversify four nuclear tests and firing means. In 2022, in particular, DPRK launched more than 40 ballistic and cruise missiles and provoked them in various ways, such as developing solid rocket engines, flying fighter jets, and invading drones. In addition, reprocessing facility activities have been observed again since 2021 at the Yongbyon Nuclear Research Complex. Operational activities such as continuous activities of the 5MWe Yongbyon reactor and the additional construction of new buildings are observed. DPRK’s recent activities could result in nuclear weapons in all except conventional weapons provocations. DPRK has researched and developed nuclear weapons since the 1950s. It has been preparing to operate nuclear weapons, operating nuclear power, and modernizing nuclear power simultaneously. Given the number of nuclear weapons using DPRK’s nuclear materials and various means of missiles, an offensive transition is expected to enable restrictive deterrence strategies that can be used first use and on assured retaliation. In addition, based on the nuclear strategy, which is interpreted as Vipin Narang’s nuclear doctrine and nuclear posture, DPRK is also capable of assured retaliation and asymmetric escalation posture. In particular, considering the continuous activities of the Yongbyon Nuclear Research Complex, which has recently diversified the investment vehicle, and the delegation of nuclear weapon use, it is expected to move differently from the previous one based on the changed nuclear strategy. However, there are clear limitations to interpreting it as a completely assured retaliation and asymmetric expansion nuclear strategy. First, there is a lack of development of atmospheric reentry vehicles that can avoid ICBM interception for assured retaliation capabilities against the United States. Second, there are limitations in the open capacity of nuclear weapons due to the absence of SSBN capabilities. However, delegation to operations at strategy force suggests the possibility of asymmetric expansion strategies. The previous analysis of DPRK’s nuclear strategy and limitations is valid in that the U.S. nuclear umbrella guarantees the Republic of Korea in a strong alliance between the Republic of Korea and the U.S. If the Republic of Korea lacks a nuclear umbrella due to the weakening of the alliance or limits U.S. intervention by having more than dozens of ICBMs, it is considered that DPRK can use a definite confirmation retaliation and asymmetric escalation nuclear strategy. As a response to this, it is the first way to verify and strengthen the validity of the three-axis system (Kill Chain, KAMD, KMPR), second to strengthen the Korea-U.S. alliance, and finally to appeal to the international community and increase consensus. In particular, it is possible to form a consensus of sanctions and condemnation DPRK by expressing concerns about nuclear dominoes caused by nuclear proliferation and arms competition to the international community.

Background: People these days use smartphone extensively as a means of diverse social activities, but excessive use of it has also created increasing forward head posture (FHP) with neck pain. To improve this FHP, neck stabilization exercise is necessary. Objectives: This study was to investigate the effects of stabilization exercise using biofeedback on FHP subjects with neck pain. Design: A non-randomized, controlled intervention study. Methods: This study chose 18 college students in their 20s whose neck disability index (NDI) was equal to or higher than 10 and cranio-vertebral angle indicated FHP as experimental group. The control group selected 18 persons with no neck pain and a normal range of cranio-vertebral angle. The stabilization movement was performed by applying three phases of pressure, with low of 20 mmHg, intermediate of 25 mmHg, and high of 30 mmHg, using the Stabilizer. To check the effects of stabilization exercise according to pressure, the circumference of deep neck muscles was measured with ultrasonic waves, and the activity of surface muscle of sternocleidomastoid (SCM) was measured using electromyography (EMG). Results: When the circumference of the deep neck flexor was analyzed according to the pressure change during stabilization exercise, the experimental group showed increase at all pressures. The activity of the SCM of the surface muscle increased in both groups as the pressure increased. Conclusion: The application of stabilization exercise was found to be more effective on forward head posture subjects with neck pain at lower pressures.

이 연구는 국가 위기관리체계 중 통합방위사태와 경계태세의 발령기준 을 개선하기 위해 분석하였다. 우리 정부와 군은 평시 북한의 침투 및 도발과 같은 상황에 대응하기 위해 경계태세 및 통합방위사태와 같은 국 가 위기관리체계를 지속 발전시켜 왔다. 그러나 북한의 도발 상황을 고 려하여 통합방위사태와 경계태세가 시기적절하게 선포 및 발령되어야 함 에도 불구하고 그렇지 못한 사례가 여럿 있다. 따라서 통합방위사태 선 포절차와 경계태세의 발령조건을 반드시 개선할 필요성이 있다. 이를 위 해 기존 선행연구 사례를 통해 공통적인 연구의 경향들을 분석하였고, 위와 같은 문제가 발생하는 원인을 관련 법령 분석을 통해 연구문제를 도출하였다. 또 과거 위기대응사례를 분석하여 연구문제에 대한 결론을 내림과 동시에 발전 방향을 제시하였다. 이를 통해 본 논제가 주는 함의 는 첫째, 북한의 태도가 급변하여 예측할 수 없는 군사적 도발을 하더라 도 유연하게 대응하고 신속하게 대처할 수 있는 위기관리태세를 갖추어 야 한다는 것이며 둘째, 이러한 적시적인 위기관리를 통해 정부는 우리 국민들의 안전을 수호하는 역할을 수행해야 한다는 점을 시사하고 있다.

본 논문은 백제 사비시대 부여와 익산의 왕실사찰인 정림사지, 제석사지, 그리고 미륵사 지에서 출토된 3점의 塑像에 대한 분석을 통해 6세기 후반~7세기 전반 백제 미술의 對中交 流 양상을 고찰했다. 구체적으로는 3인이 하나의 세트를 이루는 세속 인물상의 자세 및 의복, 그리고 두 보살상의 두발 표현 등을 중국 남북조시대 및 隋唐代 자료와 비교분석하였다. 3인상의 경우, 남북조의 출행도 및 예불도와 유사성이 지적된 바 있었다. 본 연구에서는 먼저, 기존 연구가 남북조시대 출행도에서 나타나는 지역적 차이를 간과했음에 주목했다. 3 인의 자세, 인물 구성, 侍者의 성별과 역할, 그리고 폐슬과 소매가 넓은 포복의 형태 등에서 나타나는 차이를 실마리로 백제 3인상이 북조가 아닌 남조 문화와 더욱 밀접하게 관련되어 있음을 확인했다. 무왕이 건립했다고 전하는 제석사지와 미륵사지에서 발견된 두 점의 보살상 頭部에는 連 弧形 髮際線이 출현한다. 연호형 발제선은 중국에서는 이미 4~5세기부터 출현했지만, 중국 전역으로 보급된 것은 대략 6세기 말부터이며, 그 연원은 장안양식과 관련이 있다. 연호형 발 제선은 삼국에서는 7세기에 비로소 등장하며, 이후 통일기 신라에서 유행한다. 그러므로 백제의 두 사찰 출토 소상에서 출현하는 연호형 발제선은 6세기 말부터 백제가 행한 적극적인 수 당 교류의 결과이자, 백제 미술에 미친 수당대 장안양식의 한 사례로서 주목할 만하다.
