Maintaining the permanence of a company in the current rapidly changing business environment is not an easy task. Rather, the lifespan of a company can be said to be gradually decreasing. As such, the author of this paper, which describes the current market environment, is the sales organization of a large company. While leading the company, I thought about how to overcome the rapidly changing market and create an organization that continues to grow. As a result, I succeeded in creating an organization that continued to grow over the past two years, and the main activity of this result was the use of sales computer. It was clear that it was an information sharing activity. This can be said to be a result of proving that a series of activities to create and share information is important for the sales organization of ICT companies to actively respond to the rapidly changing market environment. Therefore, this study attempted to examine the relationship between knowledge management and business performance in the sales field of ICT companies, which has not been covered so far. Knowledge management is a four-stage activity from a process perspective, divided into knowledge creation, knowledge storage, knowledge transfer, and knowledge utilization. did. As a result of the study, first, knowledge management activities, such as knowledge creation and knowledge storage, were found to have a significant impact on financial performance. Second, knowledge management activities such as knowledge creation, knowledge storage, knowledge transfer, and knowledge utilization were all found to have an impact on non-financial performance. In the end, this study confirmed that efforts to turn tacit knowledge into knowledge in order to respond to the ever-changing ICT market are ultimately an important factor in growing a company.

Background: The Nordic hamstring exercise is a closed-chain exercise that effectively activates all lower extremity muscles, but there is a lack of consideration of ankle joint which affects exercise effectiveness. One of the major advantages of the Nordic exercise have been known as strengthening lower extremity extensors. This manifests the exercise increases activities of the ankle plantar flexors as well as hip extensors. Objectives: To investigated the impacts of changes in ankle position on the lower extremity musculature and subjective difficulties during the Nordic hip extension exercise. Design: Cross-sectional study. Methods: Twenty the healthy male participants participated in this study. Participants perform three variations of the Nordic exercises including three ankle positions. Each Nordic exercise was defined as ankle position (neutral, dorsiflexion and plantar flexion). During the Nordic exercise, erector spine (ES), gluteus maximus (GM), biceps femoris (BF), gastrocnemius (GCM) activities and subjective difficulties (Borg RPE score) were measured. Results: Muscular activities of the biceps femoris and gastrocnemius were significantly different among the three ankle conditions, which showed controversial results (P<.05). The biceps femoris activity was significantly higher with the dorsiflexion condition, compared to the others (P<.05). On the other hand, activity of the gastrocnemius was significantly higher with the plantarflexion position compared to the others (P<.05). Conclusion: Present study suggests the ankle positional changes could affect lower muscular activities during the Nordic exercise. Although it is difficult to affirm the causes due to limited data, selective activation of the biceps femoris might accomplish with ankle dorsi flexion and that of the gastrocnemius might accomplish with the ankle plantarflexion during the Nordic exercises.

Hypertension is characterized by excessive renin-angiotensin system activity, leading to blood vessel constriction. Several synthetic compounds have been developed to inhibit renin and angiotensin-converting enzyme (ACE). These drugs often have adverse side effects, driving the exploration of plant protein-derived peptides as alternative or supplementary treatments. This study assessed the phenolic compound and amino acid content and the antioxidant and antihypertensive activity of 5 South Korean staple crops. Sorghum had the highest phenolic compound content and exhibited the highest antioxidant activity. Millet grains, particularly finger millet (38.86%), showed higher antihypertensive activity than red beans (14.42%) and sorghum (17.16%). Finger millet was found to contain a large proportion of branched-chain, aromatic, and sulfur-containing amino acids, which are associated with ACE inhibition. In particular, cysteine content was positively correlated with ACE inhibition in the crops tested (r=0.696, p<0.01). This study confirmed that the amino acid composition was more correlated with the antihypertensive activity of grains than the phenolic compound content. Finger millet mainly contained amino acids, which have higher ACE inhibitory activity, resulting in the strongest antihypertensive activity. These findings underscore the antihypertensive potential of select crops as plant-based food ingredients, offering insight into their biological functions.

The purpose of this study is to identify the major peacekeeping activities that the Korean armed forces has performed from the past to the present. To do this, we collected 692 press releases from the National Defense Daily over the past 20 years and performed topic modeling and social network analysis. As a result of topic modeling analysis, 112 major keywords and 8 topics were derived, and as a result of examining the Korean armed forces's peacekeeping activities based on the topics, 6 major activities and 2 related matters were identified. The six major activities were 'Northeast Asian defense cooperation', 'multinational force activities', 'civil operations', 'defense diplomacy', 'ceasefire monitoring group', and 'pro-Korean activities', and 'general troop deployment' related to troop deployment in general. Next, social network analysis was performed to examine the relationship between keywords and major keywords related to topic decision, and the keywords ‘overseas’, ‘dispatch’, and ‘high level’ were derived as key words in the network. This study is meaningful in that it first examined the topic of the Korean armed forces's peacekeeping activities over the past 20 years by applying big data techniques based on the National Defense Daily, an unstructured document. In addition, it is expected that the derived topics can be used as a basis for exploring the direction of development of Korea's peacekeeping activities in the future.

Mid-sized manufacturing companies, which account for 0.7%(5,480 companies), 13.8%(1.169 million persons) of total employment, and 15.7% of total sales, have recently experienced a lot of difficulties in management activities due to the impact of COVID-19, the U.S.-China trade war, and the collapse of global supply chains. To overcome this, revitalization of quality management activities to strengthen corporate competitiveness is emerging as an urgent task. In order for these quality management activities to achieve their intended purpose, the positive leadership of corporate managers is very important above all else. There have been many studies related to positive leadership, but most have focused on charismatic leadership and transformational leadership centered on large companies or small and medium-sized enterprises. Therefore, this study aims to present ways to strengthen the leadership of managers by empirically analyzing how the positive leadership of managers of mid-sized manufacturing companies, which was relatively under-researched, affects quality management activities and Business performance(Balanced Score Card; BSC).

This study investigated the antioxidant activities of wine made with aronia (Aronia melanocarpa). The ethanol concentration of the aronia wine was increased up to 7.8±0.1% on the 8th day of fermentation. Compared to other types of wine, the total amount of organic acids was highest in raspberry wine, followed by grape wine, arona wine, and aronia juice. Because, acetic, oxalic, and succinic acids were not detected in the aronia juice, but were detected in the aronia wine, it was determined that they were produced during alcohol fermentation. The polyphenol content in the aronia juice and wine was higher than in the grape wine and raspberry wine and was twice as much in the aroni wine than in the aronia juice. The flavonoid content in aronia juice and wine was higher than in commercial grape wine and raspberry wine. The DPPH radical scavenging ability was higher than 50% in the aronia wine and juice samples. ABTS radical scavenging activity was higher in aronia juice and wine than in raspberry wine and grape wine. The results of this study suggest that the development of wine with high antioxidant activity is possible if wine is made with aronia.

This research focused on the regional and temporal attributes of tuff architecture in Mokpo, spanning the Japanese colonial period and the post-liberation era. It aimed to uncover the distinct regional and temporal features of tuff architecture by integrating concepts from vernacular architecture and regionalism, framed through a lens of critical regionalism. The study traced the historical progression of tuff architecture in Mokpo within this context. A significant part of the research was an in-depth analysis of four constructions by Son Yang-dong, a renowned technician in post-liberation Mokpo, to closely examine the contemporary relevance and regional significance of his work. Tuff, as an indigenous material, distinctly articulates the local architectural character. In line with regional properties of tuff, the material has adeptly responded to contemporary construction needs. This has laid a foundation for the development of innovative building designs and techniques. Tuff architecture is particularly noted for its exhibition of raw material textures, offering a unique aesthetic that diverges from classical Western architectural styles. Importantly, through the examination of Son Yang-dong's contributions, the study highlights the role of Korean builders in an industry dominated by Japanese influences during the colonial period, underscoring a strong regional identity. As a representation of Mokpo, tuff architecture not only upholds and protects regional identity within the broader scope of Western modernization and Japanese impacts but also plays a role in its progressive enhancement.

목적: 본 연구는 가정방문 개별 작업중심회상치료와 센터기반 개별 작업중심회상치료가 지역사회 경증치매노인 의 인지기능과 일상생활활동에 미치는 영향을 비교하여 알아보고자 하였다. 연구방법: 본 연구는 무작위 대조군 사전-사후 설계(randomized control group pretest-posttest design)를 적용하여 충청지역의 치매안심센터에 등록된 지역사회 거주 경증치매노인 10명을 대상으로 실험군 5명, 대조군 5명으로 배정하였다. 실험군은 가정방문 개별 작업중심회상치료, 대조군은 센터기반 개별 작업중심회상 치료를 실시하였으며, 각 중재는 총 10회기로 주 1회, 회기당 60분으로 구성되었다. 평가도구는 인지기능 평가를 위한 알렌인지수준판별검사(Allen Cognitive Level Screen, ACLS)와 일상생활활동을 평가하기 위한 노인일상활동평가-복합(Seoul-Instrumental Activities of Daily Living, S-IADL)을 사용하였다. 결과: 집단 내 전후 비교량 비교 시 ACLS는 실험군에서만 점수의 차이가 유의미하였고(p < 0.05), S-IADL은 실험군과 대조군 모두 유의미한 차이를 보였다(p < 0.05). 집단 간 변화량 비교 시 ACLS는 집단 간 차이가 유의미하였고(p < 0.05), S-IADL에서는 유의미하지 않았다(p > 0.05). 결론: 본 연구에서는 지역사회 거주 경증치매노인을 대상으로 가정방문 개별 작업중심회상치료를 적용하여 인지기능 향상에 대한 단기적인 효과를 확인하였다. 본 예비연구는 국내에서 앞으로 시행될 가정방문 인지프로 그램의 근거와 방향성을 제시하였다는 측면에서 임상적인 의미가 있다.

코로나 이후 시기가 도래하며 세계 각국은 빠른 경제 회복을 목표로 다양한 노력을 강구하고 있다. 이러한 측면에서 고성장기업에 관한 관심 역시 지속해서 높아지고 있는데, 지금까지 이루어진 다양한 고성장기업의 연구를 통해 국가 경제발전이나 고용 창출에 있어 고성장기업의 높은 기여도가 입증되었기 때문이다. 이처럼 기존 고성장기업 관련 연구의 경우 국가 경제 차원, 특히 고용 창출에 있어서 고성장기업의 역할을 강조하고 있다. 하지만, 혁신 관점에서 고성장기업의 역할을 언급하고 있는 연구는 많지 않다. 이에 본 연구에서는 기업 재무 데이터와 과학기술정책연구원의 2021년 한국기업혁신조사(KIS)(서비스업 분야)를 병합한 통합데이터를 구축하고 서비스업 고성장기업의 혁신 활동과 혁신성과에 대해 분석해보았다. 방법론 측면에서는 고성장기업이 갖는 특성으로 인해 발생할 수 있는 선택편의 문제를 해결 하기 위해 성향점수매칭방법론을 활용하였다. 분석 결과를 살펴보면 서비스업 고성장기업은 일반기업 대비 더 다양한 혁신 활동을 통해 더 많은 혁신성과물을 창출하고 있는 것으로 나 타났다. 특히, 상품혁신이나 비즈니스 혁신성과물 창출에 있어서 고성장기업이 긍정적인 역 할을 한다는 것은 기존 경제·사회적 관점에서 강조되어오던 고성장기업의 중요성을 혁신성 장 관점으로 확대하여 해석할 수 있는 결과이다. 다만, 연구·개발 유형이나 협력 R&D에서는 일반기업과 차별점을 찾을 수 없었는데, 이는 협력 연구·개발 강화를 통해 고성장기업이 보 유한 혁신역량이 일반기업자들에게 파급될 필요가 있음을 보여주는 결과이다. 이상의 분석 결과를 바탕으로 본 연구에서는 국가 혁신역량 강화를 위한 고성장기업 육성과 모니터링의 필요성, 고성장기업의 협력 활동 유인 통한 혁신의 파급효과 확대 등의 시사점을 제시하고자 한다.

Alpha activities can be used for categorization, transportation, and disposal of radioactive waste generated from the operation of nuclear facilities including nuclear power plants. In order to transport and dispose of such low- and intermediate-level radioactive waste (LILW) to the Wolsong LILW Disposal Center (WLDC) at Gyeongju, the gross alpha concentration of an individual drum should be determined according to the acceptance criteria. In addition, when the gross alpha concentration exceeds 10 Bq/g, the inventory of the comprising alpha emitters in the waste is to be identified. Gross alpha measurements using a proportional counter are usually straightforward, inexpensive, and high-throughput, so they are broadly used to assay the total alpha activity for environmental, health physics, and emergency-response assessments. However, several factors are thoughtfully considered to obtain a reliable approximate for the entire alpha emitters in a sample, which include the alpha particle energy of a particular radionuclide, the radionuclide that is used as a calibration standard, the uniformity of film in a planchet, time between sample collection and sample preparation, and time between sample preparation and counting. Korea Atomic Energy Research Institute (KAERI) have evaluated the inventory of radionuclides in low-level radioactive waste drums to send every year hundreds of them to the WLDC. In this presentation, we revisit the gross alpha measurement results of the drums transported to WLDC in the past few years and compare them with the concentrations of alpha emitters measured from alpha spectrometry and gamma spectrometry. This study offers an insight into the gross alpha measurement for radioactive waste regarding calibration source, self-absorption effect, composition of alpha emitters, etc.

The primary objective of radiological environmental monitoring after a radiological emergency at a nuclear facility is acquisition of background data for the determination of protective actions for the population and the comprehensive assessment of the impact on the population residing in proximity to the nuclear facility. The responsible entities engaged in the conduct of the radiological environmental monitoring encompass government organization and nuclear licensees, operating in strict adherence to the national radiological disaster prevention framework. In accordance with the national radiological disaster prevention framework, radiation environmental monitoring is executed through the deployment of emergency response organization, and recurrent exercise drills aimed at augmenting responsible capabilities. In the context of radiation environmental monitoring, it is necessary to specify measurement parameters, monitoring location, and methodological protocols for each stage, considering potential exposure pathways. In terms of equipment, it is important to utilize mobile assets such as aerial or vehicle surveys for rapid and accurate radiation environment monitoring. Radiation disaster drills are regularly conducted, and the radiation environment monitoring field is also regularly trained to enhance response capabilities. The scale of these drills may vary, ranging from exclusive participation by nuclear licensees to joint exercises conducted by governmental agencies. This iterative process of periodic drills and equipment enhancements has led to a progressive augmentation of environmental monitoring capabilities, ensuring a well-coordinated orchestration of radiation monitoring within the framework of radiation protection. Notwithstanding these achievements, challenges in public communication regarding the decision to take protective actions and the dissemination of information to the public. Considering that the purpose of radiation environmental monitoring extends beyond safeguarding public health; it also serves to alleviate public anxiety. In the future, public communication between these stakeholders should also be included in disaster drill programs to ensure proper consultation between each stakeholder during drills and to build understanding and trust in radiation environmental monitoring. This is expected to improve the quality of radiation environmental monitoring response capabilities.
