The application of the electric propulsion system to the vessels has recently become common due to the latest technology for controlling the electric motors with variable speed. However it has been found that harmonic distortion exists in the electric propulsion system, which consists of an electric motor, a converter and an inverter, and this harmonic distortion has a harmful effect on the system. In this paper, the definition of the harmonic distortion and problems caused by the harmonic distortion in the electric propulsion of the vessels are introduced and the practical solutions for the problems are investigated.

Purpose: Kangaroo mother care (KMC) was introduced in Indonesia 30 years ago, but the extent of its use has not been fully documented. Therefore, this study aimed to examine the use of KMC and evaluate the characteristics of infants who received KMC at Koja District Hospital in North Jakarta, Indonesia. This retrospective cohort study recorded the characteristics of infants with birthweights less than or equal to 2,200 g at the above-mentioned hospital. Methods: Data collected from infant registers included gestational age, birthweight, Apgar score, number of complications, history of neonatal intensive care unit treatment, and KMC status. Cox regression analysis was conducted. Results: This study found that 57.7% of infants received KMC. Infants with birthweights over 1,500 g were 2.16 times (95% CI: 1.20-3.89) more likely to receive KMC. Conclusion: Efforts to promote KMC are recommended, specifically for infants with birthweights greater than 1,500 g. KMC for infants with other conditions can also be considered based on the infants' stability.

국가의 재정지원은 대학의 구성원인 교수 학생 연구원에게 양질의 교육 및 연구가 이루어 질 수 있도록 기회를 제공한다. 국가적 예산의 유입과 한시적인 성격이라는 특수하게 조직된 대학특별사업단의 기록물은 또한 특별하게 바라볼 필요가 있다. 이러한 배경으로 조직된 대학특별사업단에서 생산되는 기록물은 사업의 평가와 투명한 예산 집행의 증거로써 관리되어야 하고 연구의 결과물로써 활용 될 수 있음에도 불구하고 타 대학기록물에 비해 관리가 취약하다. 이유는 사업단이 기록물을 생산하고 있음에도 불구하고 처리과로 인정되지 않고 한시적 기관의 특성으로 인해 생겨나는 문제점들로 기록물관리가 미흡할 수밖에 없기 때문이다. 본 연구는 전북지역 J대학에서 수행되고 있는 대학특별사업단(이하 사업단)의 기록관리 현황을 분석하고 문제점을 도출하여 이에 대한 개선방안을 제안하는 것을 목적으로 수행되었다. 이를 위해 교육부가 지원하는 5대 사업단을 연구대상으로 선정하였다. 문헌조사를 통한 선행연구조사를 시작으로 사업단 담당자 및 전문가 등 총 12명을 대상으로 면담을 진행하였다. 현황분석과 도출한 문제점을 바탕으로 사업단 기록물관리가 이루어질 수 있도록 개선방안을 제도적 인식적 관리적 시스템적 측면에서 제안하였다. 제도적 측면과 인식적 측면을 통해 관련 제도 및 규정을 정립하여 기록물관리가 정당성을 가질 수 있는 근본적인 틀을 마련하고자 하였다. 관리적 측면에서 각 요소들이 체계적인 기록물관리를 위하여 이루어진 관계와 주어진 역할은 무엇인지 정의하였다. 이를 바탕으로 시스템적 측면에서 통합아카이브시스템의 구축을 위한 방안과 현재 사용되고 있는 시스템 및 2017년 도입될 "코러스"와 연계방향을 제안하였다.

This paper presents the results of the reliability analysis of PAU (Preliminary Assembly Unit) seat of the floating Production Storage and Off1-loading Unit (FPSO) The main aim of the analysis was to demonstrate that a sufficient safety of structural members is guaranteed against PAU loads, internal and external pressure, and hull girder moments. Topside loads for PAU design are based on owner's request. According to the seat type, topside loads are classified into maximum values of same seat type for design efficiency. Totally, 26 loading cases for each model are used for this analysis with the combination of the reactions of PAU loafing and the hull girder bending moments according to LR offshore (2). The analysis results are evaluated according to the acceptance criteria for yielding given in LR offshore and guidance note (3) and The panel buckling resistance is verified by LR offshore and SDA (4). For 900,000 bbls FPSO, the PAU support foundation analysis using 3-D F.E. model is carried out to verify the structural adequacy of PAU foundation and structure members in way of PAU. The modified structures in way of PAU support are safe against considered load cases and all stresses in way of PAU support are within design criteria.

The purpose of this GWP project was two-fold:(1) to launch an organizational culture improvement for great workplace (2) to improve the perception of nursing personnel on communication and team work in a surgical nursing department of a teaching hospital in Seoul. Using one group pretest-posttest design, nursing personnel's perception on organizational culture related to communication and team work was evaluated. A 10-item, 5-point scale (1.5) survey was administered to 209 nursing personnel in January 2009 and again to 191 nursing personnel in October 2009. From January 2009, AMANNA team has taken activities focused on trust, pride, and fun. AMANNA is an abbreviation of Korean language, which means wonderful meeting and sharing in English. Monthly activities are as follows: choral concerts by nurse managers, welcome and farewell events, praising members for their services, explaining current circumstances, etc. Special activities are as follows: a New Year's greeting party, a spring picnic, beauty classes, a lecture on drug administration, cultural lectures using videos, and presentations of academic posters and another activity. The reliability of measurement was Cronbach's ${\alpha}$: 0.917(pretest), 0.954(posttest). Most nursing personnel's perception on organizational culture was improved (pretest mean=3.50 and posttest mean=3.78, p<.001). "A sense of belonging" showed the greatest improvement among the 10 items(3.18 vs. 3.56, p<.001). "Trust each other" showed the highest score (mean=3.98) in posttest. Frequency of participation and satisfaction showed a significant relationship(r=0.179, p=.021). We believe that this project has made a contribution towards a positive organizational culture. The keys to this initiative's preliminary success have been the leadership support and flexibility in implementing the interventions tailored to the hospital.

Back pain is painful for people at a lower lumber(L4/L5 or L5/S1). It is experienced as a most frequent disaster 70％ of workers have suffered from back-pain. Especially, the occurrence rate of back pain for nurses is very high. Therefore, this study investigates female nurses who worked as a part of a medical cost management team, which mainly deal with the medical insurance in a general hospital at Seoul area. These nurses had different job tasks, which used computers for 50％ of their time, so it can be treated as VDT workers. As a first step of this project, a muscle fatigue was measured for these special VDT workers. First, survey for nurses was conducted to figure out what is a real problem of them. Second, to evaluate an experimental data, a medical cost management team was chosen for subjects. Areas of measurement were 3 places that were the trapezius (TR), the medial deltoid (MD), and the erector spine muscle (ES: L4/L5). These areas are most frequently used, so they were chosen for this study. Measurements were taken before work and after work. From these measurements, it was revealed that a fatigue really comes from their main VDT task excluding natural fatigue after work, so their work environment need to be corrected.

It is well known in KM (Knowledge Management) literature that a certain amount of knowledge is necessary for KM to contribute corporate performance to some extent. However, It is considerably difficult for a company to amass knowledge due to limited time and lack of understanding from employees. In this respect, DAEWOONG, one of leading pharmaceutical company in korea, shows very special knowledge management activity, SOP(Sucess of project), by which DAEWOONG succeeds in catalyzing the knowledge sharing process among members and cultivating men of ability. Also, DAEWOONG improve working performance at an individual level as well as team level. This case will help understand how important the knowledge management activity is to improve the corporate performance.
