본 연구는 도서관 혹은 정보센터의 중요업무인 문헌탐색을 처리하는데 있어, 어떤 방법이 보다 신속하고 비용이 적게 들며, 효율적인가를 알아보기 위해 수작업탐색과 온라인탐색의 비용·효과를 비교·분석하였다. S대학교 의과대학 도서관에서 MEDLINE 데이터 베이스와 그에 해당하는 색인지 Index Medicus를 이용하여 6개의 질문을 탐색하였다.

This Study attempts to analysis the degrees of the efficiency of fisheries marketing channel's effectiveness, which are traditional marketing channel's effectiveness of fisheries wholesale markets and Discount Store's effectiveness such as margin, marketing performance. The study methodologies include not only a field sample survey but also a field interview. The results of this study are summarized as follows. First, at the numbers of fisheries marketing channel's margin factors, traditional marketing channel's margin factors are more than discount store's margin factors. Secondly, at the comparative study result of marketing channel margin efficiency, traditional marketing channel's prices are similar to discount store's prices. That is, consumers have bought similar retail price's seafood products through traditional marketing channels as well as discount stores cannels. Finally, however most consumers prefer discount stores to traditional retail stores because of discount store's multi-functions such as assortment of goods, freshness, exchange, refund and employee's kindness. In conclusion, the most important factor of fisheries marketing management is to realize the appropriate balance between marketing margin and consumer satisfaction.

The purpose of this study is to assess for scattering object for the missile ejection round due to analysis of the human body effectiveness safely. To achieve this goal the measurement method of scattering objects by comparative 2 measurement methods studied, the risk of scattering of the object is evaluated. Result of this study, applied in Europe and Japan, based on the safety criteria for the human body effectiveness when missile ejection round. data showed is not effectiveness to the operator's body safely. Data showed that satisfies the safety criteria for missile ejection round in Europe and Japan through the similarity for the case studies. In case of these safety criteria does not exist regulation in South Korea, this study will be referred as guidelines are considered.

This research centers around an experiment conducted to determine the relative effectiveness of constructivist cooking activities as compared to traditional cooking activities for young children. Forty-six children, aged five years in two kindergarten classes were assigned to a experimental and comparative group. The experimental and comparative group participated in 12 units. The experimental group participated in the constructivist cooking activities, while the comparative group participated in the traditional cooking activities. Analysis of covariance revealed significant differences between the mean scores of the two groups on the posttests for scientific attitudes and creativity, indicating that the children in the experimental group performed significantly better on the tests than the children in the comparative group. The results of this study suggest that such constructivist cooking activities are able to improve the scientific attitudes and creativity of young children.

Objectives: The purpose of this study was to investigate and analyze the demands for educational programs on clinical trials of Korean medicine devices, and develop training programs based on the needs of Korean medicine. Methods: This research was conducted targeting 26 volunteer applicants who had participated in clinical trials of Korean medicine devices within the last five years (2010-2015). The survey was carried out between May 1, 2015 and May 26, 2015 via e-mail. After receiving questionnaire replies, the material was established. Using obtained data, frequency analyses were performed using SPSS 20.0 version. Results: 92% of the researchers who participated in the survey expected introduction of educational programs on clinical trials and anticipated that programs contain information that can meet the needs of each researcher. In addition, according to the analysis, introducing expert certification for clinical trials of Korean medicine devices is necessary, and offering related graduate courses are also needed. Conclusions: As a result of this study, researchers had difficulties during clinical trials of Korean medicine devices. If the educational programs were to be developed and institutional frameworks support them effectively, it would prove to be helpful to researchers in clinical trials.

Objectives: The purpose of this study was to analyze the medical cost of facial paralysis in payer perspective and to estimate the practice pattern of patient using 2011 Health Insurance Review & Assessment Service-National Patients Sample(HIRA-NPS). Methods: Basic statistical system was used for descriptive analysis of NPS dataset. A table for general information (table20) was extracted by disease code, and social demographic characteristics, distribution of the use among inpatients and outpatients, utilization of each kind of medical care institutions, medical cost were analyzed. Subgroup analysis was conducted for assuming the practice pattern of korean medicine and western medicine. Results: A total of 8,219 people and 64,345 claims data were identified as having facial paralysis. Proportion of outpatient was 95.23%, inpatient 0.84% and patient using both services 3.93%. Mean patient charges was 44,229 won per outpatient, 178,886 won per inpatient and 523,542 won per patient using both services. Utilization of korean medical care institutions was 68.81%(claims), 40.46%(patients), utilization of western medical care institutions was 31.19%(claims), 59.54%(patients). The amount charged by korean medical care institutions was 52.61% and western medical care institutions was 47.39%. Cost per claim was higher than those of the korean treatment and cost per patient of western treatment was lower than those of the korean treatment. Conclusions: The research assessed the medical cost and practice pattern associated with facial paralysis. These findings could be used in health care policy and subsequent studies.

The various film cooling hole shapes have been proposed for effective external cooling of gas turbine blade. In this study, the film cooling effectiveness by three different hole shapes (cylindrical hole, $15^{\circ}$ angle anti-vortex hole, 30-7-7 fan-shaped hole) were examined experimentally. Pressure Sensitive Paint (PSP) technique was used to measure the film cooling effectiveness. The coolant to mainstream density ratio was 1.0 and three blowing ratios of 0.5, 1.0, and 2.0 were considered. Results clearly showed that the effect of hole shape on the distribution of film cooling effectiveness. For the cylindrical hole case, the film cooling effectiveness decreased remarkably as the blowing ratio increased due to the jet lift off. Because of large hole exit area and low coolant momentum, the 30-7-7 fan-shaped hole case showed the highest film cooling effectiveness at all blowing ratio, followed by the anti-vortex hole case.

Although corporate punishment-related systems are being implemented in several countries, such as South Korea's Serious Accidents Punishment Act (SAPA), related research has mainly focused on legal issues. This study aimed to compare and analyze the SAPA and Singapore's Workplace Safety and Health Act (WSHA) and Code of Practice on Chief Executives' and Board of Directors' Workplace Safety and Health Duties (WSHD). In addition, it was attempted to draw implications to enhance the effectiveness of the CEO's safety and health duties. For this study, a comparative analysis was conducted in 3 steps. In step 1, similar overseas systems were investigated. In step 2, the system contents were classified into four viewpoints (DUTY, RESOURCE, Other factors, and Main contents), and comparison items were derived from each viewpoint. In step 3, the viewpoints were compared, and implications were derived. The following three implications were derived through comparative analyses. 1) In WSHD, additional explanation and calibration of measures clarify the CEO's role, and 2) It is easy to use for the CEO's duties by providing the resources directly. 3) Penalties for violating the proposed duties are entrusted to the existing higher-level laws. Considering this, providing detailed content and related information for the CEO would possibly improve the SAPA to fulfill his/her duties through announcements from related organizations in the future.
