This research studies the adequate size standard of Seogwipo cruise terminal CIQ facility that is scheduled to be built around Gangjeong harbor area in Seogwipo-city. In order to respond to the highly increasing number of passenger cruise ships compared to Seogwipo cruise terminal design in 2010, the adequate size standard of Seogwipo cruise terminal CIQ facility was examined for passenger service level grade. Based on size computation elements such as the number of passengers of cruise ships with the largest size of port entry, ship landing rate, passenger processing ratio, and surge factor, the CIQ facility size for each service level grade was reviewed. As a result, the area of 2,971m2 (A grade), 2,409 m2 (B grade), and 2,088 m2 (C grade) were computed. This showed that the area of B grade was about 82% and C grade 70% compared to the area of A grade. The CIQ facility size computed for each service level grade in this research was analyzed that its area needed to be increased by 322% at least and 458% at most, compared to the CIQ facility area of 649m2 of the existing design (2010). In order to respond to the increasing number of cruise passengers, provide high-level passenger service, and improve the international image of Jeju, Seogwipo cruise terminal should secure the size that is equal to or higher than the B grade of service level.

본 연구의 목적은 노인장기요양보험 이용자의 장기요양등급 유지 및 변경특성을 분석하고, 장기요양서비스 이용자의 등급유지에 영향을 미치는 요인을 파악하는 것이다. 이를 위해 국민건강보험공단 노인장기요양보험의 원자료(인정 및 급여자료)를 활용하여 2008-2014년 장기요양 급여를 이용한 자를 분석 대상으로 로지스틱 회귀분석을 실시하였다. 분석 대상자를 등급집단(1-3등급)별로 구분하여 인구사회학적 요인, 질병요인, 서비스 요인으로 분석하였다. 분석 결과, 인구사회학적 요인에서 1, 3등급에서 64세 미만자가 80세 이상자보다 등급을 유지할 가능성이 높게 나타났다. 3등급에서 독거자가 비독거자에 비해, 농어촌거주자는 대도시거주자에 비해 등급을 유지할 가능성이 높게 나타났다. 질병 요인에서 1등급에서 치매보유자가 등급유지 가능성이 높게 나타났으나, 2, 3등급에서 반대로 나타났다. 2등급에서 중풍, 골절 보유자가 등급유지 가능성이 높게 나타났고, 3등급에서 암보유자가 등급유지 가능성이 높게 나타났다. 서비스요인에서는 2, 3등급에서 갱신횟수가 높을수록 등급유지 가능성이 높게 나타났다. 1등급에서 시설이용일수가 높을수록 등급유지 가능성이 높게 나타났고, 2등급에서 재가이용일수가 높을수록 등급유지 가능성이 높게 나타났다. 이상의 분석결과를 통해서 장기요양서비스 이용자를 위한 제도개선에 대한 이론적, 정책적 시사점을 제시하였다.

This study was to investigate factors and disclose causal model of the scientific literacy competency about the motivation for science and the scientific literacy competency. The 3 grade university students and the 1 grade university students as pre-service elementary teachers were participated to questionnaire investigation. The data were analyzed by the factor analysis method and the structural equation model method, and the following results were obtained. First, the 3 grade university students and the 1 grade university students perceived the science interest factors and science usefulness factors as the motivation for science, and also revealed the scientific problem recognition factor and the scientific evidence use factor as the scientific literacy competency. Second, the science interest factor had a greater effect on the scientific problem recognition factor than the scientific evidence use factor in both the 3 grade and 1 grade university students. In the path from the science usefulness factor to the scientific problem recognition factor, the science usefulness factor of the 3 grade university students had a greater influence on the direct route to the scientific problem recognition factor than that of the 1 grade university students. In the path from the science usefulness factor to the scientific evidence use factor, the science usefulness factor of the 1 grade university students influenced more on the direct route to the scientific evidence use factor than that of the 3 grade university students.

Factors and causal structures of pre-service elementary teachers about the critical thinking and the scientific literacy competency were investigated in this study. The third grade university students and the first grade university students in the metropolitan city participated in this study. The factor analysis method and the structural equation modeling method were used for the data analysis, and the following results were obtained. First, the third grade university students and the first grade university students recognized 'inquisitive thinking' factor and 'reflective thinking' factor as factors of the critical thinking, and 'scientific explanation' factor and 'evidence-based conclusion' factor as factors of the scientific literacy competency respectively. Second, the third grade university students showed more the influence from 'reflective thinking' factor to 'scientific explanation' factor and from 'reflective thinking' factor to 'evidence-based conclusion' factor than the first grade university students.

The purpose of this study was to investigate the relationship among staffing, occupancy rate, upward level change of long-term care need, and evaluation grade of facility. Data were obtained from National Health Insurance Corporation Database. Occupancy rate and evaluation grade were highest in National/public operating facilities, while they were worst in individual operating facilities. The percents of A or B grade in evaluation grade (by newly enforced law) is highest in National/public operating facilities. Multiple regression analysis showed that upward level change of care needs was very weakly associated with the number of doctors. Evaluation grade showed a weak and significant association with occupancy ratey(by old-version law)(r=.20, p<.01), upward level change of care need in group home(r=.23, p<.01) Staffing in facility did not show significantly consistent association with upward level change of care needs, evaluation grade, and occupancy rate.

A grading system is implemented to evaluate the meat quality of Hanwoo. In the grading system, grade 1++A is the highest grade. Livestock farms breed Hanwoo with good quality feed in order to obtain the highest grade. In this process, the content ratios of muscles in individual regions can be changed. To find out the muscle distribution ratios of Hanwoo steers, grade 1A, 1+A, and 1++A Hanwoo steers were compared with grade 1+A Hanwoo female. Grade 1A Hanwoo steers had higher ratios of shank (SK), brisket and flank (BF), neck chain (NC), and inside skirt (IS) meats and a lower ratio of striploin (SL) meat compared to grade 1+A Hanwoo feamle. Grade 1++A Hanwoo steers had higher ratios of neck (NK) and loin (LN) meats and lower ratios of inside skirt (IS), tenderloin (TL), top round (TR), eye round (ER), bottom round (BR), bottom sirloin triangle (BST), and knuckle (K) meats compared to grade 1+A Hanwoo steers. In comparison between grade 1A and 1++A Hanwoo steers, the ratio of shank (SK) was significantly lower in higher quality meats. If the changes are continuously studied to improve the process so that the ratios of partial meats of the regions highly preferred by consumers can increase, it will contribute to increases in the incomes of livestock farms and enable Hanwoo to grow into a global brand.

본 연구에서는 전단력과 도체등급 판정항목간 상관관계 분석을 통한 육질평가의 자료로 사용하기 위해 한우암소 200두를 대상으로 하였고, 세부적으로 성숙도와 전단력과의 상관관계를 조사하여 기계적인 연도 측정상에서의 성숙도와 연도간의 상관관계를 분석하고자 실시하였다. 본 연구결과, 육량등급이 낮아질수록 전단력이 낮아져 매우 높은 부(-)의 상관관계가 있는 것으로 나타났으며, 육질등급 항목 중 육질 1차등급과 최종등급은 전단력과 높은 상관관계가 있었으며, 그 중에서도 근내지방도는 매우 높은 상관관계가 있는 것으로 나타났다. 그러나 육색, 지방색, 조직감은 전단력과 직접적인 상관관계가 없는 것으로 나타났다. 한우 암소 성숙도는 육질등급판정에서 하향조정항목으로 설정되어 있으나 도체 성숙도에 따른 전단력의 차이에서는 성숙도 4가 $452.04\;kg/cm^2$로 가장 높은 전단력을 나타낸 반면, 성숙도 5가 $413.11\;kg/cm^2$로 가장 낮은 수치를 나타내었으며, 성숙도 2가 $417.98\;kg/cm^2$이었던데 반하여 성숙도 9는 $428.80\;kg/cm^2$을 나타내어 성숙도와 전단력(기계적 연도측정치)과는 상관관계가 없는 것으로 나타났다. 추가적으로 성숙도와 관련하여 전단력 뿐만 아니라 보수력 및 관능 특성인 다즙성, 향미 등의 종합적인 분석이 가능한 연구조사가 수반된다면 보다 객관적이고 과학적인 육질등급 판정을 위한 자료 확보가 가능할 것이다.

Recently IPTV service is penetrating to the ordinary home users very swiftly. One of the first phase of IPTV service is considered to be VoD, and a nationwide availability of the VoD service imposes tremendous pressure to the network resource due to its requirements for the broad bandwidth, the inherent nature of unicast technology, and the large scalability, etc. This work suggests a novel and practical method to the design of network resource for the VoD service. Especially, we explore the distributed content storage problem that takes into account the popularity of the video contents and its corresponding link dimensioning problem that takes into account the grade of service for the flow level quality of service about the VoD service. By assuming a realistic topology for the nationwide IP backbone network of Korea, which is a typical tree topology, we suggest an analytic method for the design of VoD service.
