목적 : 이 연구는 납점작업자를 대상으로 납점작업으로 유발될 가능성이 높은 눈, 호흡기, 피부 등의 증상호소율 및 노출강도에 따른 관련성을 파악하기위해 수행되었다. 방법 : 연구참가자 146명중 연구목적에 적합한 20명을 제외한 126명을 대상으로 '눈이 가렵고 충혈됨', '코가 가렵거나 파가움', '재채기', '콧물'. '코막힘' , '목이 따끔거림' , '목에 무언가가 걸려있는것 같음' , '갑자기 연속적인 기침을 함' , '운동 시에 다른 사람에 비해 숨이 가쁨', '숨을 쉴 때 쌕쌕하는 소리가 남', '가래가 끓음', '손이나 안면에 가려움을 느낌' , '안면에 여드름이 날' '손이나 안면에 붉은 반점이 남' 등 14가지 증상에 대한 경험유무와 혈중연농도, 납점작업의 건강위험요인에 대한 지식상태 등을 조사하였다. 결과 : 조사된 14가지의 증상 중, '갑자기 연속적인 기침을 함'이 하루 납점시간 4시간 이상인 군아서 4시간 미만인 군보다 유의하게 증상호소율이 높았으며, 다른 증상의 경우 하루 납땜시간에 따라 유의한 결과를 보이지 않았다. 납땜작업의 건강위험요인에 대한 질문에 12.8 %가 플럭스에 의한 건강위험을 지적하였다. 전체 대상자의 평균 혈중연농도는6.05 rg/dL였으며, 히고치는 15.50 rg/dL이었다.결론 : 납땜작업자에게 호흡기 증상의 위험이 높을 가능성이 있으며, 납땜작업의 건강위험에 대한추가적인 연구와 납점작업자들을 대상으로 납점작업에 의해 유발될 수 있는 건강장해에 대한 적극적인교육 및 홍보활동을 필요로 한다. Objectives : This study was conducted to evaluate the prevalence of ocular, respiratory and skin symptoms among solderers and to investigate the relationship between symptom prevalence and exposure intensity. Methods : We analyzed 126 eligible participants out of a population of 146 male solder-ers who completed the symptom questionnaires. Fourteen symptoms including 'itchy and red eyes', 'itchy or prickly nose', 'sneezing', 'rhinorrhea', 'blocked nose', 'prickly throat', 'foreign body sensation in throat', 'sudden bouts of coughing', 'exertional breathlessness', 'wheezing', 'sputum production', 'itchy face or hands', 'acneiform erup-tions on the face' and 'red spots on the face or hands' were contained. Blood lead levels of all the 126 participants were tested and the participants' own assessments of the health risk of soldering were collected. Results : Of the 14 investigated symptoms, 'sudden bouts of coughing' was significantly more prevalent in solderers who worked 4 hours or more a day than those who worked less than 4 hours a day, as for the other symptoms, there were no significant differences in the prevalences related to daily soldering hours. 2.8% of the solderers considered the risk of flux exposure to be serious. The mean blood lead bevel was 6.05 μg/dL (maximum 15.50 μg/dL). Conclusions : Soldering may increase the risk of respiratory symptoms. Further invert tigations on the hazards of soldering processes are warranted and solderers should be educarted on these hazards.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

The proliferation of the internet and related applications has made users struggle with information overload. It means users must spend more time to find and gather necessary information they want. The agent technique is advocated by many researchers as an alternative to overcome the difficulty, which resulted in the practical use of the agent technique in Electronic Commerce more common. In this paper, we propose a realtime price comparison agent which compares the prices and services among online stores in realtime without users' intervention. The proposed agent differs from the existing ones in that (1) it does not incorporate a pre-installed price database, (2) it automatically monitors users' current status without any input from the users.

김정구,박진택,최윤석,부진효,유용재 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.6

The corrosion failure of electronic devices has been a major reliability concern lately. This failure is an ongoing concern because of miniaturization of integrated circuits(IC) and the increased use of polymers in electronic packaging. In this paper plasma-polymerized thiophene films were considered as a possible candidate for an interlayer dielectric for multilever metallization of ultra large scale integrated (ULSI) semiconductor devices. The protective ability of above films as a function RF power in an 3.5 wt.% NaCl solution was examined by electrochemical methods and contact angle measurement. The protective efficiency of the film increased with increasing RF power, which induced the higher degree of cross-linking and hydrophobicity of the films.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

This paper introduces trust measurement that is composed of trust variables and fuzzy cognitive map. The improved trust measuring method using a stratified FCM can be used to measure the level of risk involved in a specific auction transaction concerned. To reduce the auction transaction cost and time, the proposed system recommends a differentiated transaction protocol according to the risk based on trust measurement. In this system, trust measurement can also be applied for differentiated and varied auction services.

Liquid phase oxidation of p-xylene using molecular oxygen has been carried out on the Co/Mn/Br-based catalyst system in acetic acid as a solvent. Process parameters(total pressure, partial pressure of oxygen and temperature) and kinetics of the reaction were studied as a basic study in the viewpoint for the development of new catalyst system and process. The total pressure above 20atm and the partial pressure of oxygen above 5atm were required to keep the reactant in the liquid phase and to overcome the mass transfer limitation of oxygen. The oxidation rate conversion were increased with increasing reaction temperature to the 100∼190℃ range. For a given initial concentration of p-xylene, the oxidation rate and the apparent activation energy were found to be of first-order and 4.24 ㎉/㏖, respectively. The effect of the third components added to the Co/Mn/Br catalyst was also studied. It was found that Ni is only a good additive that can promote the catalyst performance.
