To examine the result of the government Medical Aid Program which began in January, 1977 as a part of social security policy implementation, all the medical records of the clients and official statistics in the year were analysed. The specific objectives this study pursues include the magnitudes and patterns of morbidity and utilization, and the characteristics of clients. One Korean rural area, Koje county was selected as the study area and subsequently all the clinics and hospitals assigned to work out the Aid Program are the subjects for the survey. A brief summary of the sutdy results as follows: a. The clients of Koje county are 6.4% of the total population in the area, more than the average percentage of the clients in Korea. It reflects on low level of economic status of the residents of the area. b. The population structure of the clients indicates that the large proportions of young and old age group are overwhelming, while the middle age group share very small portions. c. The utilization rates for primary care are 2.0 persons, 11.6 visits and 22.6 treatment days per 100 persons per months. Annual hospitalization is rated as 13.7 cases and 164 days per 1,000 persons, The utilization rates are slightly lower than those expected rates during planning period but eventually become higher than those of general population in rural Korea. d. The factors which influence the utilization rates are identified with client group (low income vs indigent), age and sex. e. The utilization pattern for primary care demonstrates seasonal variation similar to the pattern of general rural population in the low income group, but none in the indigent group. f. The most common diseases revealed at the primary care clinics are the acute respiratory infection (26.9%), acute gastritis (10.8%), skin and subcutaneous infection (6.8%). The cases of acute conditions are outnumbered than the cases of chronic condition. 8. The clinics, hospitals and other related health institutions are well cooperated in dealing health care services in their own capacities. Considering the above results Medical Aid Program generated satisfactory results at least in the utilization aspect.

Purpose: This study aimed to identify utilization of the work-family support policy (WFSP) and factors affecting retention intention among Korean female military officers. Methods: This cross-sectional survey recruited 103 married female officers from the Korean Army, Navy, and Air force with preschool-aged children through convenience and snowball sampling. Via online surveys from June to November, 2018, the participants self-reported retention intention, work-family conflict, job satisfaction, and utilization of the WFSP. The data were analyzed using descriptive statistics, independent t-tests, one-way analysis of variance, Pearson's correlation coefficient, and multiple linear regression. Results: Retention intention ($22.29{\pm}5.98$) was reported at the mid-level, lower than scores reported in the literature for female workers. Work-family conflict ($32.51{\pm}5.29$) and job satisfaction ($63.10{\pm}7.45$) were above the midpoint levels. Use of maternity leave (100.0%) and parental leave (92.2%) was high, especially compared to the rates of child-care day off (20.4%) and parenting time (20.4%). 'Noticeable increases in childcare services within the army' (22.8%) was reported as the supportive measure needed the most by female military officers. Job satisfaction (${\beta}=.43$, $p{\leq}.001$), the use of parenting time (${\beta}=-0.29$, p=.002), living type (${\beta}=-.18$, p=.043), and service type (${\beta}=-.16$, p=.035) significantly influenced retention intention. Conclusions: The findings highlight the priority areas of importance within the WFSP and suggest that a family-friendly culture can improve female officers' retention intention. Accordingly, policy changes at the Ministry of National Defense improving the system to enhance a family-friendly culture in the military is expected to strengthen the retention intention of female officers and contribute to excellence in the military workforce.

BIM과 건설사업관리(Construction Management; 이하 CM)는 건설정보를 통합 관리하고 신뢰성 있는 의사결정을 지원하는 수단이라는 점에서 그 성격이 유사하기 때문에 BIM은 CM에 효율적으로 활용할 수 있으나, CM 분야에서 BIM 도입은 미흡한 실정이다. 이 연구의 목적은 시공단계의 CM 업무에 BIM을 효과적으로 활용할 수 있도록 업무절차 모델 및 가이드를 제시하는 것이다. 문헌조사를 통해 BIM 기능을 BIM 전환설계, 모델 검토, 데이터 추출, 자동 견적, 4D 시뮬레이션, 도면 생성, 엔지니어링 분야 연계분석 등으로 정의하고, CM 업무와 프로세스를 분석하여 BIM의 적용이 가능한 CM 업무를 도출하였다. BIM 기능과 CM 업무 간 연관성 분석을 통해 기존의 업무절차를 BIM 기능과 연계하여 재구성하고, 사업 참여자별 역할을 재정립하여 BIM기반 CM 업무절차 모델을 개발하였다. 개발된 모델의 효용성을 향상시키고자 면담조사와 사례조사를 통해 사업 참여자들의 BIM 업무를 기술한 가이드를 작성하였다. 또한 BIM기반 CM 업무절차 모델의 활용성을 검증하기 위한 선행연구의 BIM 프로세스와 비교 분석하고 전문가를 대상으로 설문조사를 수행하였다. 이 연구는 CM 분야에서 BIM의 활용성을 높이는데 기여할 수 있다. 향후에는 사례적용을 통해 실무적 관점에서 모델을 평가할 필요가 있으며, BIM 도입으로 인한 CM 업무의 확대를 고려하여 지속적으로 BIM기반 CM 업무절차 모델을 업데이트할 필요가 있다.

The purpose of this study was to investigate the work-family reconciliation level of married women in double-income households. Specifically, the study aimed to test the positive spillover effects, asymmetry, and differential functions of work-family reconciliation. The study thus analyzed 1,114 married women in double-income households in the third-year data of the Korean Longitudinal Survey of Women and Families (KLoWF) done by Korean Women's Development Institute (KWDI), with the exception of those who were separated, divorced, or widowed from their husbands. The data were put to descriptive statistics, frequency analysis, and exploratory factor analysis using SPSS 20.0 for Windows. AMOS 20.0 was used to test the hypothesis on positive spillover effects, asymmetry, and differential functions. The analysis results confirm that work-family conflict, family-work conflict, work-family facilitation, and family-work facilitation are different concepts, thus supporting the hypothesis on positive spillover effects. Secondly, the negative effects of family on work were greater than those of work on family, whereas the positive effects of family on work were greater than those of work on family, which finding partially supported the hypothesis on asymmetry among the components of work-family reconciliation. Finally, the married women in double-income households with preschool children experienced more work-family conflict and family-work conflict than those with no preschool children, which result supported the hypothesis on differential functions between the two groups of women. The findings were combined to provide implications for the utilization of family resources, policies for work-family reconciliation, and plans for institutional supports to promote the work-family reconciliation of married women in double-income households.

The objective of this thesis to Provide a better insight into the effect of the amount of in-process storage has on the efficiency of production line with variable operation times. It is assumed that the material enters the line at the first work station and is then processed progressively through the line until it exits at the last work station, a finite amount of in-process storage is provided before all but the first work station of the line and the operation time of the work stations are statistically independent and follow exponential distribution. Under the above assumption, optimum allocation model is developed and following two approaches are used : 1) Given the available storage capacity, optimum allocation which minimizes the number of items in the line. 2) Given the available storage capacity, optimum allocation which. maximizes the utilization factor of the line. In a balanced three stage line, the production line efficiency is maximized under both categories when the second in-process storage is larger than the first.

Although many research efforts have been conducted to address the effect of crew members' work skills (e.g., technical and planning skills) on work performance (e.g., work duration and quality) in construction projects, the relationship between skill and performance has generated a great deal of controversy in the field of management (Inkpen and Crossan 1995). This controversy can lead to under- or over-estimations of the overall project schedule, and can make it difficult for project managers to implement appropriate managerial policies for enhancing project performance. To address this issue, the following aspects need to be considered: (a) work performances are determined not only by individual-level work skill but also by the group-level work skill affected by work team members, each member's role, and any working behavior pattern; (b) work planning has significant effects on to what extent work skill enhances performance; and (c) different types of activities in construction require different types of work, skill, and team composition. This research, therefore, develops a system dynamics (SD) model to analyze the effects of both individual-and group-level (i.e., multi-level) skill on performances by utilizing the advantages of SD in capturing a feedback process and state changes, especially in human factors (e.g., attitude, ability, and behavior). The model incorporates: (a) a multi-level skill evolution and relevant behavior development mechanism within a work group; (b) the interaction among work planning, a crew's skill-learning, skill manifestation, and performances; and (c) the different work characteristics of each activity. This model can be utilized to implement appropriate work planning (e.g., work scope and work schedule) and crew management policies (e.g., work team composition and decision of each worker's role) with an awareness of crew's skill and work performance. Understanding the different characteristics of each activity can also support project managers in applying strategic work planning and crew management for a corresponding activity, which may enhance each activity's performance, as well as the overall project performance.

Objective : The aim of this study was to survey the present utilization of pattern identification(PI) in the clinical field among Korean Medicine Doctors. Method : This survey was conducted from Oct. 1 to Oct. 31, 2014 by face-to-face interview using structured questionnaire. The subjects were 400 korean medicine doctors who worked in hospitals or clinics. The questionnaire consisted of two sections - a demographics section(i.e., sex, age, clinical experience, place of work, residence and so on) and the main research section(i.e., the PI utilization rate, the utilization of PI systems, the utilization of PI in the clinical domain and in the treatment domain, the correlation between utilization PI and so on). Results : This study revealed that subjects used the PI to 66.7% of their patients on average. The utilization rate of PI in patients was significantly higher for female physicians than for male physicians, for physicians worked in clinics than for physicians who worked in hospitals and for physicians with more than 10 years clinical experience than for physicians with less than 10 years clinical experience. In the utilization of PI systems, Visceral PI was most as 92.0%. There were significant difference on the PI utilization rate according to utilization of Meridian and Collateral PI, Triple Energizer PI, Defense, Qi, Nutrient and Blood PI, Six-Meridian PI and Six Excesses PI. As a result of analysing the PI utilization rate by clinical domain and in the treatment domain, the Treatment and the Drug Treatment showed the highest values. Among utilized PI systems, the correlation coefficients between Defense, Qi, Nutrient and Blood PI and Triple Energizer PI showed the highest value, but the correlation coefficients between Sasang Constitutional Medicine with the each PI showed substantially lower value. Conclusion : The results of this study demonstrate that usage of PI was higher than usage of U code(in KCD) usage in clinical field. we suggested that additional studies on using PI and developing more appropriate standardized tool should be conducted to widen scope of PI's utilization.

While prior work has noted the importance of knowledge creation in gaining competitive advantages, much less is understood about why firms do not actually use what they create. Building upon institutional approaches to organization studies, we offer a new framework to explain the gap between knowledge creation and utilization. We test our framework in an empirical context of sustainable innovation and environmental technologies where ideas of environmental sustainability have recently gained public popularity and shaped how interested audiences make evaluative assessments of firms. In such a context, firms are apt to perceive the social attention toward sustainability to be a normative pressure, which causes them to create new knowledge and develop technologies consistent with the pressure. Using data from the government-initiated certification system for green technologies, our study finds that firms do not always fully implement new environmental technologies they develop in response to the certification program, the situation we refer to as knowledge decoupling. We also examine a set of conditions under which knowledge decoupling becomes more or less amplified. Taken together, our findings show how a firm's knowledge creation and utilization is shaped by its external institutional environment as well as internal learning processes.

"파리 협정"을 통해 출범된 신기후체제에 따라 세계 각국에서 온실가스를 감축하기 위한 정책과 연구가 수행되고 있으며, 우리나라에서도 온실가스 감축을 위한 대책 마련이 시급한 실정이다. IEA 보고서에 따르면 에너지 부분의 $CO_2$ 배출량이 전체 배출량의 2/3에 해당하기 때문에 온실가스 감축을 위해서는 단기적으로는 화석연료 사용을 대체할 수 있는 신재생에너의 생산과 적용 기술 개발과 에너지효율개선 기술 도입이 최선이며, 장기적인 관점에서는 온실가스를 포집하고 활용하는 온실가스 포집 및 활용(CCUS, Carbon Capture Utilization and Storage) 기술 개발이 필수적이다. CCUS 기술은 온실가스를 직접적으로 감축시키는 기술로 활발하게 연구되고 있는 기술이다. 본 논문에서는 다양한 CCUS 기술 개요 및 연구 현황과 향후 전망에 대해서 살펴보았다.
