        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.

        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.

      • TCP over ATM의 성능 개선에 관한 연구

        이진우,박기태,김진태,김래진,박인갑,Lee, Jin-Woo,Park, Ki-Tae,Kim, Jin-Tae,Kim, Nae-Jin,Park, In-Kap 한국전기전자학회 1998 전기전자학회논문지 Vol.2 No.1

        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.

        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.

        이진우,문은수,김성재,한수봉,강응식,Lee, Jin-Woo,Moon, Eun-Su,Kim, Sung-Jae,Hahn, Soo-Bong,Kang, Eung-Shick 대한족부족관절학회 2003 대한족부족관절학회지 Vol.7 No.2

        Introduction: Soft-tissue impingement syndrome is now increasingly recognized as a significant cause of the chronic ankle pain. As a method to detect soft-tissue ankle impingement, a characteristic history and physical examination, routine MR imaging, and direct MR arthrography were used. The efficacy of routine MR imaging has been controversial for usefulness because of low sensitivity and specificity. Direct MR artrhography was recommaned for diagnosis because of the highest sensitivity, specificity and accuracy, but it requires an invasive procedure. The purpose of this study is to investigate the diagnostic accuracy of Fat suppressed, contrast enhanced, three-dimensional fast gradient recalled acquisition in the steady state with rediofrequency spoiling magnetic resonance imaging(CE 3D-FSPGR MRI) and to evaluate the clinical outcome of the arthroscopic treatment in assessing soft-tissue impingement associated with trauma of the ankle. Materials and Methods: We reviewed 38 patients who had arthroscopic evaluations and preoperative magnetic resonance imaging studies(3D-FSPGR MRI) for post-traumatic chronic ankle pain between January 2000 and August 2002. Among them, 24 patients had osteochondral lesion, lateral instability, loose body, malunion of lateral malleoli, and peroneal tendon dislocation. The patient group consisted of 23 men and 15 women with the average age of 34 years(16-81 years). The mean time interval from the initial trauma to the operation was 15.5 months(3 to 40 months), The mean follow-up duration of the assessment was 15.6months(12-48 months). MRI was simultaneously reviewed by two radiologists blinded to the clinical diagnosis. The sensitivity, specificity and accuracy of MRI was obtained from radiologic and arthroscopic finding. Arthroscopic debridement and additional operation for associated disease were performed. We used a standard protocol to evaluate patients before the operation and at follow-up which includes American Orthopedic Foot and Ankle Society Ankle-Hindfoot Score. Results: For the assessment of the synovitis and soft tissue impingement, fat suppressed CE 3D-FSPGR MR imaging had the sensitivity of 91.9%, the specificity of 84.4 and the accuracy of 87.5%. AOFAS Ankle-Hindfoot Score of preoperative state was 69.2, and the mean score of the last follow-up was 89.1. These were assessed as having 50% excellent(90-100) and 50% good(75-89). The presence of other associated disease didn't show the statistically significant difference(>0.05). Conclusion: Fat suppressed CE 3D-FSPGR MR imaging is useful method comparable to MR arthrography for diagnosis of synovitis or soft-tissue impingement, and arthroscopic debridement results in good clinical outcome.

        Purpose: The purpose of this study is to review clinical and radiologic changes after arthroscopic operation without bone graft for osteochondral lesion with subchondral cyst on the talus. And we compared the results with those without cyst. Radiologic changes were also observed. Materials and Methods: Arthroscopic microfrature or abrasion arthroplasty was performed on 10 caeses of osteochondral lesions with subchondral cyst and 20 cases without cysts. Preoperative and postoperative symptoms were evaluated by Ankle-Hind foot scale of AOFAS and the score of two groups were compared(t-Test : Paired Two Test for Means). Radiologic evaluation was performed after operation on patients with osteochondral lesion with cyst. Results: On patients of osteochondral lesion with subchondral cyst on talus, there was clinical improvement compared to the preoperative status and compared to patients without cysts(P=0.01) after arthroscopic operation. We could get increase of density and decrease of size of cystic lesion on plain film with time passage. Conclusion: We report 10 cases with osteochondral lesion with subchondral cyst on talus which resulted in clinical and radiological improvement after arthroscopic microfracture or abrasion arthroplasty without bone graft.

        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.

        본 연구에서는 동수압 모형을 이용하여 트렌치 수로에서 발생하는 흐름해석을 실시하였다. 기존의 정수압 모형은 수식이 간단하고 수치기법의 적용이 상대적으로 쉬운 반면 수심이 파의 길이에 비해 상대적으로 작은 경우에만 적용이 가능하므로 수심이 커지게되면 비 물리적인 결과를 계산하게 된다. 따라서 흐름방향으로 밀도차가 큰 경우나 수중구조물로 인하여 바닥경사가 변하는 경우에는 동수압이 고려되어야 한다. 본 연구에서는 압력항을 정수압과 동수압으로 분리하고 일반 좌표계를 사용함으로써 자유수면이 매시간단계마다 변화하는 계산격자를 구성해야하는 문제점을 보완할 수 있었다. 자유수면과 동수압을 고려하기 위해서 계산단계를 3단계(정수압 계산단계, 동수압 보정단계, 자유수면 보정단계)로 나누어 해석하였고 트렌치 수로에서의 수리실험 결과 (van Rijn, 1982)와 비교를 통해 수치모형을 검증하였다.
