STCW협약에 따른 기초안전(재)교육 및 상급안전(재)교육 등과 같은 선원 해상생존교육은 해상에서 비상상황이 발생할 경우 선원들의 생존율을 증대시켜줄 수 있는 필수교육이다. 그리고 IMO 모델코스에 따른 선원안전교육을 효과적으로 수행하기 위해서는 선원들이 다양한 안전장비에 대한 이론 및 실습교육이 병행되는 것이 매우 중요하다. 따라서 이 연구는 IMO 모델코스에서 요구하는 해상생존교육과정에 근거한 실습시설을 파악하고, 국내외 교육기관의 운영 실례를 바탕으로 관련 시설을 비교 분석하여 선원 안전교육시설 개선방안을 다음과 같이 마련하였다. 첫째, 해상탈출설비(슬라이드, 슈트 등) 등과 같은 최신화된 교육장비를 비치하여, 선원들이 다양한 안전장비를 직접 체험할 수 있는 교육환경을 구축해야 한다. 둘째, 조파, 풍동, 강우, 암막장치 등과 같은 해상환경 재현시설의 설치하여 학습자가 현실적인 비상상황을 직 간접적으로 체험해 볼 수 있는 교육환경의 구축해야 한다. 셋째, 체험교육, 시청각교육, 시뮬레이터 교육과 더불어 가상현실 교육장비를 통한 층위별 맞춤교육을 개발하고 확대시킬 필요가 있다. Seafarer sea survival training, such as basic safety refresher training and advanced safety refresher training, in accordance with the STCW Convention, is an indispensable program that can increase the crew survival rate during emergency situations at sea. It is important for crew members to carry out theoretical and practical training with various safety equipment in order to effectively train according to IMO model courses. Therefore, this study suggests the following measures to improve safety training facilities for seafarers by reviewing survival training requirements based on the IMO model course and comparing and analyzing related facilities based on operating cases from domestic and overseas training institutes. First, it is necessary to establish a training environment where seafarers can practice utilizing various, updated safety equipment such as marine evacuation equipment (slides, chutes, etc.). Second, it is necessary to construct an educational environment in which learners can directly or indirectly experience realistic emergency situations by installing marine environment simulation facilities with such equipment as a wave generator, rain fall device, wind generating device, etc. Third, it is also necessary to develop and expand customized training using virtual reality equipment in addition to experiential training, audiovisual training and simulation training.

This investigation grasps the level and relevant elements of performance of health promotional activities for the elderly in Korea. It provides fundamental data on health promoting projects targeting the elderly population from farming villages. Hence, this study gropes for an effective approach and measures of health promoting programs. The program needs to be developed with a focus on elderly people from farming villages. In addition, it was carried out in order to provide basic data for development of health projects for local communities. Data gathering was based on survey data targeting patients from the free clinic service. Service was rendered for the residents of farming villages, and conducted at the Offices of CheonBuk Province from October 2000 to December 2000. Analytical results were used to examine the health promotional method for the elderly in the aspect of Oriental Medicine. SPSS 9.0 version as well as T-test and ANOVA were used for survey data analysis. Piersons correlation coefficient was utilized for the relationship for each area, obtaining the following analytical results. 1. The average score for the activities of health promotion was 2.28. Looking at each subcategory, stress management was the highest at 3.65; interpersonal relationship, 3.00; nutrition, 2.55; health responsibility, 2.15; self-realization, 2.03; and exercise was the lowest at 1.89. 2. With respect to lifestyle of the health promotion secondary to general features of elderly people from farming villages, the level of activities of health promoting lifestyle was shown to be higher for males than that of females. Self-realization area was high among males in detailed particulars while the level of execution was high as age decreases in the stress area. 3. Regarding health promoting life style secondary to socioeconomic characteristics, the level of execution was higher for the individuals with a higher level of education and further utilization of spare time. With respect to occupation, the level was highest for people from the fishery. The level decreased in the order of other occupations such as trade, unemployed and agriculture, which was shown to be the lowest. In detailed particulars, it revealed that higher the individuals educational level, the higher the self-realization and stress management areas. The level of interpersonal relationship was the highest among people with little or no education. With respect to self-realization area, the level was highest among the cases where one paid living expenses along with their children. The lowest level of living expenses was seen in the cases where an individual pays for living expenses by himself/herself. There were significant results in all areas except for nutrition areas depending on occupation. The fishery was shown to be the highest. The level of activities was higher as one utilizes more spare time in all areas except for the area of interpersonal relationship.

The Asynchronous Transfer Mode(ATM) networks are being adopted as backbones over various parts of Internet. Also, TCP is one of the most widespread transport protocols, nowadays. It can be used with ATM. But, TCP shows poor end-to-end performance on ATM networks. Effective throughput of TCP over ATM can be quite low when cells are dropped at the congested ATM switch. The low throughput is due to wasted bandwidth as congested link transmits cells from corrupted packets. This paper examines the behavior of TCP over ATM-UBR using EPD switch in a broadband environment. With a threshold close to the buffer size, the buffer can be used more efficiently, but more drops and retransmission occurs. If the threshold is much less than buffer size, efficient is not good, but few drops can happen. Therefore, decision of the threshold is important.

SBD (Strain-based design) of pipe lines have gained world-wide attention in recent years. The present research aims to evaluate the fracture characteristics of API (America Petroleum Institute) SBD X100 girth weldment that typically applied for cold climate and deep water offshore, with the focus on the influence of heat input changing with 6kJ/cm and 10kJ/cm from GMAW (Gas Metal Arc Welding). At a low heat input at 6kJ/cm, the weld metal had Multi-phase matrix (Acicular ferrite + Banite + Martensite) that could fill up both fracture toughness and strength as reported previously. Also, the weld metal exhibited 859MPa YS (Yield strength), 108J impact toughness at $-40^{\circ}C$ and 0.52mm CTOD (Crack Tip Open Displacement) at $-10^{\circ}C$. These results can be satisfied with the requirement of API SBD X100 girth weldment and Alaska pipe line project.

Purpose: The purpose of this study is to evaluate the effectiveness of low-dose gabapentin for interdigital neuroma. Metrials and Methods: Between April 2000 and June 2003, 32 patients (39 feet) with interdigital neuroma were treated with using low-dose gabapentin. Two of the 32 patients were male, and thirty were female, and the average age was 47.4 years. The follow-up was 6 to 44months (mean 15.1 months). All cases were diagnosed by physical examination and ultrasonography or MRI. Low-dose gabapentin (300-600 mg) was prescribed and shoe modification was recommended. The patients were evaluated through questionnaire. Results: Neuroma was found in twenty one cases at the third intermetatarsal space, and thirteen at the second intermetatarsal space. The sensitivity of ultrasonography was 96% and that of MRI was 79%. Overall satisfaction was rated as excellent or good by 18 cases (57%). Average pain relief ratio was 50.3%, and in 14 cases, more than 80% of pain relief was noted. Nine (28%) of 32 patients showed they had no activity restrictions, such as daily activities or work, whereas 8 (25%) had mild restrictions and 15 (47%) had major restrictions. Twelve of 15 patient with major restrictions had been treated operatively (neurectomy; 10 cases, decompression; 2 cases). One case had gastrointestinal problem. Conclusion: Low-dose gabapentin for interdigital neuroma was one of the effective conservative treatments. The operation may be preserved for patient with the persist symptoms, nevertheless the conservative treatments and use of low-dose gabapentin.

The Asynchronous Transfer Mode(ATM) networks are being adopted as backbones over various parts of Internet. Also, TCP is one of the most widespread transport protocols, nowdays. It can be used with ATM. But, TCP shows poor end-to-end performance on ATM networks. Effective throughput of TCP over ATM can be quite low when cells are dropped at the congested ATM switch. The low throughput is due to wasted bandwidth as congested link transmits cells from corrupted packets. This paper examines the behavior of TCP over ATM with limited bandwidth in a broadband environment. As multiple VBR sources occupies most of the available bandwidth, there has been a starvation effect, so TCP sources couldn't get the chance of transmitting data. Also, throughput is proportional to the amount of buffer.

Introduction: Painful plantar callosities under the second and third metatarsal heads are not uncommonly associated with hallux valgus and there have been controversies concerning its treatment modalities. We performed the Weil osteotomy in patients with painful callosities under the second and third metatarsal head associated with hallux valgus, and evaluated the outcome clinically & radiologically. Materials and Methods: From November 2000 through November 2001, out of 51 patients diagnosed with hallux valgus, the Weil osteotomy was performed in 5 women associated with painful callosities under the second and third metatarsal heads. The mean age was 53.4 years (range, 31-66) with a minimum follow-up period of 12 months(range, 12-16). Results: The mean AOFAS lessor metatarso-phalangeal-interphalngeal Scale(LMIS) improved from 61.2 points preoperatively to 88.8 points postopertively. Mean decreases in length of the second and third metatarsal after surgery were 3.2mm and 3mm. Conclusion: We experienced improvement of metatarsalgia in 80% of patients by Weil osteotomy and all patients were symptom-free at last follow-up, suggesting that the Weil osteotomy is an effective procedure in treating painful plantar callosities under the second and third metatarsal heads associated with hallux valgus.
