        This study used both kinesiotaping and extracorporeal shock wave therapy on patients diagnosed with frozen shoulder - a common musculoskeletal disorder in adults - in order to observe the effects on the joint range of motion. 21 adult(male 12, female 9) were selected and distributed into randomized groups. One group received kinesiotaping (n=10) and the other group received kinesiotaping together with extracorporeal shockwave therapy (n=11). After a 6 week duration of receiving kinesiotaping and extracorporeal shockwave therapy, changes in the joint range of motion in the patients were observed. Post-treatment of frozen shoulder, the changes in abduction within the shoulder joint were as follows: in both groups there was a noticeable increase in the joint range of motion (p<.05). Post-treatment of frozen shoulder, the changes in external rotation within the shoulder joint were as follows: both groups showed a significant increase in the joint range of motion (p<.05). The result of suggest that, it can be inferred that both the extracorporeal shockwave therapy and kinesiotaping are effective in increasing the joint range of motion in patients with frozen shoulder.

        This study investigated the effects of indirectly applying proprioceptive neuromuscular facilitation (PNF) to the scapular adductor muscles of stroke patients on their scapular movements and walking ability. Five patients who were diagnosed with stroke participated in this study as a single group. PNF patterns were applied to the scapulae anterior elevation and posterior depression patterns and upper limbs patterns of the patients in side lying and sitting positions together. The data were analyzed with a paired t-test in order to identify within-group differences in the measurements before and after the intervention. The scapular movements of the upper and lower parts, weight bearing and walking speed were significantly improved in the stroke patients after the application of PNF (p<0.05). These results suggest that PNF training effective in improving the scapular movements and walking ability in patients with stroke.

        The purpose of this study was to determine the effects of music therapy and ball exercise on women experiencing menstrual discomforts, thereby identifying the validity of these methods as interventions against menstrual discomforts, with a particular goal of presenting basic data for clinical use. Twenty university students in their 20s were assigned to two therapy groups in a sequence via simple random sampling; ten subjects attended a ball exercise combined with music therapy group and the other ten subjects attended a music therapy group. Ball exercises were conducted 3 times per week for a total of 12 times, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Similarly, the subjects participated in music therapy by listening to music for 35 minutes per session and 3 sessions per week, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Five out of six categories of menstrual discomforts were significantly decreased in both music therapy and ball exercise, the exception being changes in the autonomic nervous system, while those in the music therapy group showed a significant difference only in the category of behavioral changes. The results of the present study demonstrate that the ball exercise combined with music therapy more effective in improving menstrual discomforts than the music therapy group.

        This study was conducted to examine the effects of medium composition on organogenesis towards in-vitro cultured diploid and tetraploid Codonopsis lanceolata and obtain in-vitro mass propagation of superior species of C. lanceolata. Regarding MS medium composition for each concentration, diploid C. lanceolata was found to be declined. However, shoot and adventitious root formation were suppressed with higher mineral salt concentration, and active growth of shootand adventitious root was exhibited as 4.9 cm and 3.2 cm respectively in 1/2 MS medium. While in tetraploid C. lanceolata, it showed 2.9 cm and 3.2 cm respectively in 1/4 MS medium. In the case of sucrose concentration, no consistent decrease was observed for growth of shoot and adventitious root of diploid both at high and low concentration. The growth of shoot (at 3% concentration) and adventitious root (at 7% concentration) was 2.3 cm and 2.0 cm respectively. Although there was no difference in shoot formation of tetraploid C. lanceolata in all concentrations with the range of 1.7 ~ 1.8, there was a slight decrease in shoot growth at high concentration. Results revealed that the adventitious root formation was suppressed at high concentration. Concentration of agar exhibited no significant difference in shoot formation of diploid C. lanceolata at all concentrations. The highest result of adventitious growth (4.1 cm) was observed at 0.8% concentration. Slight inhibition of shoot formation and root formation of tetraploid C. lanceolata was observed at higher concentration. Shoot formation of diploid C. lanceolata also exhibited inhibition at higher concentration. Shoot formation of diploid C. lanceolata was increased at lower pH and shoot growth was the highest (2.3 cm) at pH 3.8. Adventitious root formation was higher at lower pH. Although there was no difference in shoot formation of tetraploid C. lanceolata presenting 1.7 ~ 1.8 regardless of high and low pH, growth inhibition was showed at higher pH. Adventitious root formation and growth showed a little higher result at pH 5.8.

        The role of oral corrective feedback (CF) in second language (L2) learning has been extensively investigated. However, little attention has been given to the relationship between different types of CF and explicit/implicit L2 knowledge. For this reason, the present study explored the effects of recasts and metalinguistic feedback on the development of explicit and implicit knowledge of the English articles. Sixty-three university students enrolled in intermediate Communication English classes participated, and they were assigned into a metalinguistic group, a recast group, and a control group. While the students engaged in meaning-based activities (i.e., retelling stories), the feedback groups received respective CF on the errors of English articles and the control group did not receive any feedback. Untimed grammatical judgement tests were employed to measure the students’ improvement of explicit knowledge and elicitation oral imitation tests were used to examine their gains of implicit knowledge. The study found that both recasts and metalinguistic feedback equally facilitated the development of explicit knowledge over time. However, they were not as effective as in the improvement of implicit knowledge, showing a short-term effect on the development.

        The objective of the present study is to analyze whether there is a difference in visit experience that is based on scenic site types and to identify the influence factors of satisfaction with scenic site visits. In doing so, this study aims to provide policy-related implications for improving the scenic site categorization process with utilization in mind and for improving scenic site visitors’ experience and satisfaction levels. To this end, the study selected five representative scenic sites by scenic site type, categorized them based on the assumption that the scenic sites will be utilized as government- designated cultural assets, and conducted a survey among the visitors at the target sites. Through the survey, 654 samples were collected and used for ANOVA and regression analysis. Analysis results showed that scenic site visitors were found to travel by car about two hours on average and that approximately half of the visitors visit a scenic site without knowing its designation status. A similar trend was manifested in all scenic site types. The results of analyzing visitor experience in scenic sites showed that most visitors frequently experience the aesthetic and escapism of scenic sites while their education experience and the entertainment experience were relatively low. In addition, there was a minor discrepancy between the characteristics of scenic site type and the visitors’ actual experience; it is speculated that such a tendency arises because the current conditions and policy for utilizing scenic sites fail to fully reflect the characteristics of the resources that each scenic site has. The result of analyzing the influence factors on scenic site visit satisfaction showed that visitors’ experience levels had a stronger impact on visit satisfaction than visitors’ individual characteristics or user behavior characteristics did. In conclusion, the findings of the present study have the following implications: In order to eliminate the discrepancy between the characteristics of scenic site type and the actual experience of visitors, it is necessary to establish utilization strategies based on scenic site types; in order to improve scenic site visitors’ satisfaction levels, it is crucial to promote a scenic site utilization policy that focuses on visitor experience.

        Riptortus pedestris is a major agricultural pest in Korea. To manage this pest, it is necessary to understand the complete life history of R. pedestris. However, most studies have focused on the summer period when the pest attacks crops. Therefore, we conducted laboratory and field experiment to identify overwintering behavior of adult R. pedestris. First, we conducted two laboratory experiments to examine overwintering habitat preferences and spatial distribution of R. pedestris in the habitat. Second, we conducted field survey to characterize overwintering sites of R. pedestris in diverse landscapes. In the laboratory conditions, R. pedestris almost exclusively showed overwintering behavior in the leaf litter arena (63%) among the structures tested (rocks: 3%; rotten wood: 0%). And spatial distribution of R. pedestris showed solitary behavior in leaf litters. In the field, we located 12 individuals of overwintering adults from the urban areas, whereas no individuals were found from the high-elevation mountains and agricultural landscapes. Our results suggest that R. pedestris mainly use leaf litter as an overwintering structure, with solitary behavior, and low-elevation forested areas near urban landscapes seem to be more preferred overwintering sites.

        선박 및 플랜트의 배관은 제작부터 설치까지 일련의 과정을 모두 현장에서 하는 것이 아닌, 외부의 공장 또는 숍으로부터 배관의 제일 작은 요소인 스풀 배관을 제작하고, 이를 작업현장 또는 현장 근처의 공장에서 모듈화 또는 가설치 작업 및 현장에서 직접 설치작업을 통해 제작이 된다. 이 과정에서 스풀은 3D CAD를 기반으로 하는 것이 아닌 2D 도면을 기반으로 하기 때문에, 작업공간을 고려하지 못할 수 있다. 이러한 이유로 실제 설치작업 시 작업공간의 방해로 인한 공기의 지연을 발생 시킬 수 있다. 본 논문은 이러한 스풀 배관의 설치 시 또는 운용 및 유지보수 시에 생길 수 있는 외부 구조물과의 스풀 위치에 관하여, 스풀 위치가 외부 구조물로부터 방해를 받지 않도록 하기 위한 방법으로 유전 알고리즘을 적용하여 스풀 위치를 결정하는 방법에 대해 제시하고자 한다.

        체세포 복제기술을 이용한 복제가축 생산 기술은 1997년 전 세계적으로 이슈가 되었던 복제 면양 “Dolly”의 탄생을 계기로 여러 나라에서 소, 돼지, 말, 고양이, 개 등 많은 포유류에서 산자 생산에 성 공하였으며 우리나라의 체세포 복제 기술은 기술 선진국 대열에 들어서고 있다. 그러나 복제기술은 아 직까지 높은 유산율과 폐사율 등 해결해야 할 많은 근본적인 문제점 등이 있어 연구해야 할 분야는 적 지 않다고 하겠다. 체세포 복제 동물 생산기술은 당초에는 능력이 우량가축의 생산과 확대 및 조기증식 을 목적으로 이용되고 왔으나, 체세포 내로 우리가 원하는 유전자를 도입시키거나 없애는 기술 (knock-in과 knock-out)의 발달로 바이오장기 생산용 형질전환 복제 돼지의 생산을 목적으로 널리 이 용되고 있다. 또한, 최근에는 멸종위기에 있는 희소동물 유전자원을 멸실 이전에 동결 보존된 체세포를 이용하여 복원에 활용할 뿐 아니라 마약탐지견 생산 등 특수한 목적으로 활용되는 동물을 생산하는 기 술로서 기여하게 된다면 산업적으로 활용할 수 있는 분야가 더욱 확대될 것으로 기대된다. 따라서 체세 포 복제기술은 식용보다는 오히려 다양한 목적으로 복제동물을 생산하게 되면 산업적으로 활용할 수 있 는 가능성이 높을 것으로 기대되고 있다.

        The purpose of this study compared the ability of feedback breathing training (FBT) and balloon blowing training to enhance the breathing of elderly people. The subjects were randomly and evenly divided into a feedback breathing training group (FBTG) and a balloon blowing training group (BBTG). Each group trained 3 times a week for 4 weeks, with the training suspended during the last 2 weeks. Pulmonary function measurements were obtained before the test and 2, 4 and 6 weeks after the test: forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF) and vital capacity (VC). A repeatedmeasures ANOVA was conducted for the significance test. The FBT resulted in a significant increase in the FVC, FEV1/FVC, PEF, and VC of the elderly smokers after 4 weeks and a significant decrease in the FVC, FEV1/FVC, and PEF after 6 weeks. The BBT resulted in a significant increase in the FVC, FEV1, FEV1/FVC, PEF, and VC of the elderly smokers after 4 weeks and a significant decrease in the FVC, FEV1/FVC, and PEF after 6 weeks. In conclusion, An at home breathing rehabilitation program, in addition to balloon blowing, could increase the breathing performance of elderly people.

        Bi0.5Na0.5TiO3 (BNT) based ceramics are considered potential lead-free alternatives for Pb(Zr,Ti)O3(PZT) based ceramics in various applications such as sensors, actuators and transducers. However, BNT-based ceramics have lower electromechanical performance as compared with PZT based ceramics. Therefore, in this work, lead-free bulk 0.99[(Bi0.5Na0.5)0.935Ba0.065](1-x)LaxTiO3-0.01SrZO3 (BNBTLax-SZ, with x = 0, 0.01, 0.02) ceramics were synthesized by a conventional solid state reaction The crystal structure, dielectric response, degree of diffuseness and electric-field-induced strain properties were investigated as a function of different La concentrations. All samples were crystallized into a single phase perovskite structure. The temperature dependent dielectric response of La-modified BNBT-SZ ceramics showed lower dielectric response and improved field-induced strain response. The field induced strain increased from 0.17% for pure BNBT-SZ to 0.38 % for 1 mol.% La-modified BNBT-SZ ceramics at an applied electric field of 6 kV/mm. These results show that Lamodified BNBT-SZ ceramic system is expected to be a new candidate material for lead-free electronic devices.

        본 연구는 현재 국립축산과학원 가축유전자원세터에서 보유 하고 있는 재래닭을 순수화된 품종인 것으로 판단하고, 일반 적으로 이용되고 있는 산란사료 및 사양관리 방법을 적용하여 특히, 동절기에 있어 재래닭의 정자의 보존 기간과 수정률 및 초기배자의 생존율을 각각 비교함으로써 재래닭의 생산성 향 상을 위한 기초자료를 제공하고, 나아가 표준능력을 고찰하고 자 수행하였다. 본 시험에 사용된 공시계는 39주령의 재래닭 6계통 적갈색(R, Red Brown Strain), 황갈색(Y, Yellow Brown Strain), 회갈색(G, Gray Brown Strain), 흑색(L, Black Strain), 백색(W, White Strain) 그리고 오계(O, Ogol Strain)를 대상 으로 하고 대조군으로는 3계통 즉, 외래도입종 중에서 대표적 인 다산종인 White Leghorn (F Strain), Rhode Island (C Strain) 그리고 육용종인 Cornish (H Strain)의 수정률 및 초기배자 생존율을 조사하였다. 단 한번의 인공수정 후, 3 주간 생산된 알의 수정률 확인을 한 결과, 재래닭의 경우, 6 계통간의 유의 적인 차이는 없지만 93.3 ~ 100.0비율로 인공 수정 후, 2일째 부터 수정률이 6일째 동안 최고 높음을 확인했다. 6일째까지 상대적으로 일정하게 높은 수정률을 유지하다가 7일부터 17일 째 까지 점진적으로 감소함을 확인했다. 17일 이후 생산된 알 의 경우 무정란임을 확인 할 수 있었다. 재래닭(R, Y, 그리고 O) 21일간 생산된 알의 배발생정지율의 결과, 인공수정 후, 약 4일째 생산된 알(3 ~ 6일)에서 외래도입종 3품종간의 유의적인 차이는 보이지 않았지만, 배발생정지율이 0%임을 확인하였다. 세 품종 모두 약 7일째 생산된 알부터 배발생정지율이 13.8 ~ 26.7%로 급격히 증가하고 12일부터 감소하는 것을 확 인했다. 재래닭 3 계통의 결과도 인공수정 후, 약 4 일째 생 산된 알에서 외래도입종 3 품종과 유사한 패턴을 나타내면서 배아 사망율이 6 일째까지 0%를 보였다. 금후, 체내 정자보존 기간이 수정률 및 초기배자 생존율에 미치는 영향을 좀더 엄 밀하게 조사하기 위해서는 정액 성상 및 활력 검사와 더불어 암탉의 주령에 따른 변화도 함께 보다 세부적이고 입체적인 방법의 체계적인 조사가 반드시 필요하다고 할 수 있겠다.
