Recently, there has been tremendous increase of suicide among the middle-aged men in Korea. The purpose of this study is to examine the status of job stress, family stress and suicidal ideation perceived by middle-aged married men as well as to investigate the relationships between these variables. For this study, 233 men aged 40~59, who reside at Busan and work at diverse industries, were selected. They filled out self-administrated questionnaires. The major findings of this study suggest several implications associated with suicidal ideation. First, higher position in socioeconomic status indexed by education, income, and job contributed to reduce suicidal ideation among the middle-aged married men. Especially education had consistently suppressed pressure of suicidal ideation. This result implies that education is able to promote cognitive flexibility to diffuse suicidal ideation. Second, family stress played a key role to increase suicidal ideation. Family stress originated from unstable adjustment to job identity and consistent conjugal conflicts were the most strongly associated with suicidal ideation among the middle-aged men. This finding suggests that differential levels of suicidal ideation tend to be determined by stable self-identity based on solid integration into job and family structure rather than inherent temperament and vulnerability to distress. Meanwhile, work-related stress was not a significant determinant in suicidal ideation. This result indicates that, for the middle-aged men, job-related stressors are not perceived as distress, but a possible challenge to maintain their self-esteem. Overall findings lend support to Durkheim's status integration hypothesis. Some implications associated with this hypothesis are discussed. To help reducing suicidal ideation among the middle-age married men, family counseling and family education programs ought to be implemented. Our study suggests that underlying theme of these programs put emphasis on sharing family support responsibility, diversifying lifestyles to participate all family members, and creating a family-friendly job environment.

조재영,강선녀,정창모,윤미정,허중보,전영찬 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

연구 목적: 임플란트-골 계면에서 발생하는 과도한 열은 골유착을 저해하여 임플란트의 실패를 유발한다. 이에 이번 연구에서는 임플란트 금 합금 보철물의 교합면 삭제시 임플란트-골 계면으로의 열전달 양상과 냉각 방식의 효율성을 알아 보고자 하였다. 연구 재료 및 방법: 온도 감지 장치 제작을 위하여 Internal cone 연결형태의 임플란트에 16개의K형 열전대를 부착하여 아크릴릭 레진에 포매하였다. 치과용 금 합금과 주조용 abutment를 사용하여 교합면에 3개의 요철을 가지는 시편을 10개 제작하였고, 연결 나사를 이용하여 임플란트와 연결한 뒤 온도 감지 장치를 37℃로 유지되는 수조에 위치시켰다. 저속 핸드피스와 green stone bur를 이용하여 30초 동안 보철물의 요철을 삭제하였는데, 무냉각군, 공기 냉각 군, 물 분사 냉각 군으로 나누어 요철을 삭제하였다. 보철물이 삭제 되는 동안 임플란트의 부위별로 온도가 0.05초 간격으로 기록되었고, 삭제를 멈춘 뒤에도 무 냉각 군의 경우 임계 온도인 47℃ 이하로 온도가 하강할 때까지, 공기 냉각군과 물 분사 냉각군의 경우 삭제 중단 후 30초 동안 추가로 온도를 기록하였다. 냉각 방식에 따른 임플란트-골 계면의 온도를 알아보고, 임플란트의 부위별 온도변화의 유의차를 알아보기 위하여 one-way ANOVA를 실시하였고, Turkey HSD 이용하여 95% 유의수준에서 사후 검증하였다. 결과: 무 냉각 군은 임플란트-골 계면의 온도가 47℃ 이상으로 상승하였으며, 임플란트의 경부에서 유의하게 높은 열이 측정되었다(P>.05). 공기냉각군과 물분사 냉각군은 임플란트-골 계면의 온도가 47℃ 이하로 유지되었다. 무 냉각 군에서 임플란트 경부의 온도가 47℃에 도달되는 데는 약 10.8 ± 1.5초가 소요되었다. 공기 냉각 군과 물 분사 냉각 군 사이에서는 임플란트-골 계면 온도의 유의차가 없었다(P>.05) 결론: 이상의 결과로부터 임플란트 금 합금 보철물의 교합면 삭제 시, 임플란트 주위 조직에 위해를 가할 수 있는 임계 온도 이상의 열이 발생했음을 알 수 있었으며, 냉각방식은 공기 냉각과 물 분사 냉각 모두 효과적이라고 생각된다. PURPOSE. The purpose of this study was to analyze temperature change along the implant-bone interface induced by grinding the occlusal surface of implant gold prosthesis and to compare the temperature generated by grinding of prosthesis with different cooling methods. MATERIALS AND METHODS. The experimental gold prostheses were fabricated with dental gold alloy and castable abutment. The prostheses had 3 cylindrical protrusions on the occlusal surface with 1mm in height. Temperature was measured using 16 thermocouple wires attached to the implant fixture surface and the fixture was embedded in an acrylic resin block inside the 37℃ water bath. Cylinders were grinded for a period of 30 second with a low-speed handpiece with green stone point. One cylindrical protrusion was grinded without cooling, the second one was grinded with air blow, and the third one was grinded with water-spray. RESULTS. The mean maximum temperature was measured more than 47℃ of the implant and the maximum temperature was measured at the cervical portion of the implant in the group without cooling. There was statistically significant difference between the group without cooling and the groups with cooling (P<.05). However, there was no significant difference at all portion of implant in the groups with cooling (P>.05). CONCLUSION. The results of this study support that the grinding of implant gold prosthesis without cooling may damage the peri-implant tissue. The continuous use of air blow and water-spray adjacent to prosthesis during the grinding of implant gold prosthesis may prove to be beneficial for cooling of the implant.

PFAPA (Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adenitis) syndrome has characteristic features of an early onset, periodicity (interval <4 weeks), and a brisk rising high fever (>39℃) of 3 to 6 days' duration without signs of infection. An 18-year-old male was admitted for high fever, sore throat, headache, and abdominal pain. He had suffered from periodic fevers associated with pharyngitis and cervical adenitis for 14 years without any evidence of infection. The fever recurred approximately every 4 weeks lasting 4 to 7 days with intervening asymptomatic periods. Physical examination was unremarkable except for slightly injected tonsils. Most laboratory tests including CBC were normal except for elevation of Creactive protein level (3.47 mg/dL). Bacteriologic and radiologic studies were negative. The fever was spontaneously subsided in 6 days. To our knowledge, this is the first case report of PFAPA syndrome in Korea. (Korean J Infect Dis 33:219∼222, 2001)

Petri Net을 이용한 시간논리 구조의 표현과 이산사건 시스템의 모델링

강영진,김정철,모영승 원광대학교 2001 論文集 Vol.26 No.-

시간논리 구조는 일반논리구조에 시간개념을 부가한 구조로 시간관계를 논리적으로 표현한 이론으로 정의되어 있으며 이산사건 시스템의 동작을 표현하기에 용이하다. 시간관계를 논리적으로 표현함으로써 사건의 전후 관계와 다음상태, 최종 상태 등을 표현하기에 편리하다. 하지만 시각적인 이해가 어렵다는 단점이 있다. 본 논문에서는 이를 해결하기 위해서 시간논리구조를 페트리 네트로 표현하는 방법을 제시 한다. Temporal Logic Frameworks is convenient to represent temporal relation. It is useful to represent a dynamic properties of Discrete Event Dynamic Systems, Also, it is convenient to express a current and next state of event using logical representation. Because the teachability tree of the Temporal Logic Frameworks is very complexity it is difficult to understand. In this paper, we defined some rules to represent Temporal Logical Frameworks by Petri Net and proposed am method of the representation of them Petri Net for the Temporal Logic Frameworks. An example are used to demonstrate the feasibility of this metod.

박모라,김귀영,박필숙,강우원 동아시아식생활학회 1998 동아시아식생활학회지 Vol.8 No.1

The purpose of this study was to investigate quantity food production practices in foodservices by analysing the menus of April, 1996. The questionnaire was developed and responded to by 96 dietitians in Sangju, Munkyung, Gumee, Kimchun, and Andong during November, 1996. The survey was performed by simple random samplings. The results were as follows; 1. Hospitals and industry served food for thirty days and schools for twenty days. Kimchi was a select-menu for hospitals and one side dish for industry and schools. The type of menu was a single use menu which consisted of cooked rice, soups and three side dishes. 2. The most frequently used ingredients were green onions, rice, carrots, onions, Korean radish roots, pork, eggs, glutinous rice, and milk. Kimchis were served most frequently in all food-services and cooked rices and soups were next. 3. The age of most of the respondents was 26 to 30. 54.2% of subjects were junior college graduates and 77.1% were single. Fifty-seven point three percent of the dietitians lived with family, relatives, or friends. 87.5% of the dietitians had been working for 1 to 5 years. 4. Most foodservices were self-operated. The number of meals served was determined by meal coupon counting in hospitals(37.5%), meal board counting in industry(29.2%), and attendance card counting in schools(41.1%). The cost of sales per meal was approximately 2,450 won in hospitals and was approximately 1,100 won in industry and schools. The average number of days per menu cycle was 7.4 in hospitals, 10.3 in industry and 25.5 in schools. Hospitals, industry, and schools held about 118, 265, and 263 recipes, respectively. The average number of dietitians was 2.6 in hospitals and 1.0 in industry and schools. Except for the number of recipes, the general practices of foodservices were significantly different(P<0.05). 5. In the general quantity food production, food and seasonings measuring was hardly done. The percentage of foodservices using chemical seasonings was higher in hospitals and industry than in schools. The most important concern was taste. Registered cooks were employed in 75% of schools but only 50.0% in hospitals and 20.8% in industry. Most of the dietitians responded that their cooks skill was not bad. The education of unregistered cooks was performed once or two times a month in hospitals and industry, and in schools performed everyday. The problem when educating cooks was the lack of cooking skill of the dietitians in schools, and the lack of time in hospitals, and the negative attitude toward education in industry. The method for improving cooking in all foodservices was OJT, or the extension of education facilities and the development and dissemination of standard recipes. The frequency of throwing away leftovers was higher in hospitals. But in industry, the frequency of saving leftovers was higher. 6. Though all foodservices have standard recipes, the number that used them was low. Another problem is that standard recipes resulted in leftovers. The inconveniences of using standard recipes were the difficulty of applying standard recipes to various numbers of customers the complication of use, or facility insufficiency.

Purpose: Acute pyelonephritis in older patients can lead to a poorer treatment response and prognosis. The objective of this study was to classify older female patients with acute pyelonephritis according to age and compare their clinical characteristics and antibiotic susceptibility. Materials and Methods: In this retrospective study, 360 patients aged 65 years or older and hospitalized for acute pyelonephritis in a single tertiary medical facility from 2012 to 2016 were selected as research subjects. The patients were divided into three groups according to their age. Their clinical symptoms, blood tests and urinalysis, underlying diseases, causative organisms for urinary tract infections (UTIs), and antibiotic susceptibility were compared. Results: One hundred and seventy-six patients aged 69.9±2.7 years, 142 patients aged 79.4±3.1 years, and 42 patients aged 87.3±3.1 years were assigned into the young-old, old-old, and oldest-old groups, respectively. The duration of hospitalization and fever due to acute pyelonephritis increased with age. On the other hand, the maximum body temperature was similar among the three groups. In blood tests, erythrocyte sedimentation rate and C-reactive protein increased with age. Among the underlying diseases, the incidence of diabetes and chronic renal disease was similar among the three groups, while cerebrovascular diseases, heart failure, and urinary stones were associated with aging. Older patients were more likely to have UTIs over the past year. Older groups showed a more significant decrease in sensitivity to carbapenems, amikacin, and ciprofloxacin. Conclusions: Choosing appropriate antibiotics, considering the patientʼs age, is important when treating acute pyelonephritis.

As business operations are globalized, the management information system which have been developed to support individual tasks in many companies are focused on the ineffectiveness. That in because the entire business transactions including production, accounting, personnel management, and logistics need to be integrated with a global perspective. To meet these requirements, many enterprises are planning or adopting the ERP package which has been recently assailable with the help of advanced information technologies. The target company of this study goes ahead with plan to adopt ERP systems. Hereupon, I want to present the issues which should be considered in the process of ERP system implementation. This study focuses on the manufacturing system, but it also discusses important issues on the selected business area. This study covers the material benefits and functionalities of ERP package as well as the importance of studying and understanding on business process, organization change management, and information technology. And this case study swart with a long-term plan and consider its own unique characteristics and environmental factors. But it is regrettable that I can not make a comparative analysis with other systems because the ERP system is still on the introductory stage for the company studies and the benefits have net been realized yet. Another limitation of this research is its narrow scope of study in which only the raw material inventory system for a single company is covered. In the future, however, ERP system would be adopted by many corporations, which would help us to launch a comparative study on the results of ERP system implementation as a future direction of research.

This study was carried out to improve the organic farming system about crop cultivation, compost production and application, plant diseases & pest control, weed control and marketing system of organic farming products to the case study in Chungnam Hongdong area. Agricultural technologies concerning pest & diseases control, weed control and compost production are not established due to lacks of systemized researches by the agricultural scientist, and agricultural machines profitable to this works had not developed yet. In cropping system, reasonable crop rotation had not conducted. The related cultivation of vegetables on the same ground for a long time cause a various plant disease easily. So crop rotation is a reasonable method about soil nutrient utility and soil disease control. It is a good method that introduce the barley and wheat in this field crop system. Those crop have a long root, so can use the other nutrient against the vegetable. In organic farming products, the safety and quality of products by the National Agricultural Products Inspection Center had not inspected except rice, lettus and apple. Inspection is needed for the development of organic farming and mutual confidence between producer and consumer, because the mutual confidence is a major thing to sustain the organic farming. In products marketing, it is more need for the information of organic farming products. Nowaday most products are marketed in Seoul region, but it is not a good method. To search the consumer in near region is a good method for decrease the cost of conveyance and maintain the quality of products. The varieties of distribution structure of organic farming products are required. The products are sold to department store in large city and the prices are about 30% higher than normal products. But when those are supplied in near region, the prices of those are similar to normal products. Direct transactions in near regions is a good method for decrease the cost of conveyance and strength the mutual confidence between producer and consumer.
