This study was undertaken to analyze the hygienic problems of group food services and to predict the outbreak patterns of future food-borne diseases. A delphi survey with 20 experts identified the main causes of food-borne outbreaks in group food services as improper hygienic management of raw food materials, washing of worker's hands, dividing the spaces and unsanitary retail storage. Vibrio parahaemolyticus, Escherichia coli (EPEC), non-typhoid Salmonella serotypes, Staphylococcus aureus, Escherichia coli (ETEC), norovirus, and the hepatitis A virus all have potential to cause outbreaks of food-borne disease. We analyzed the daily food use and the possibility of food-borne outbreaks in school food services for fruits, milk, fish, pork, eggs, and meat as raw food materials, and bibimbab, soybean sprouts muchim, spinach namul , cucumber sengchae, jabchae, and pork bulgogi as prepared food items. Frozen ( ≤ -20℃) and refrigerated (0~10℃) processed foods are popular items in group food services. Their storage, heating, and chemical sanitization methods are potential sources of food disease outbreaks. Our results can be applied to a well-organized hygiene control system and can be used to develop menus for preventing food-borne outbreaks.

The objective of this study was to investigate the relationship between addiction to online games and carpal tunnel syndrome (CTS) in college students. A total of 377 (205 male and 172 female) college students completed an online game addiction scale, a Symptom Severity Scale (SSS), and a Function Status Scale (FSS) for CTS. It was found that five (1.3%) students were diagnosed with an online game addiction, 74 (19.6%) students were diagnosed with a pre-addiction to online games, and 298 (79.0%) students were diagnosed as being average users. The pre-addiction group had significantly higher scores on the SSS than did the average user group (p<.05). The average user group scored significantly lower than did the online game addiction group (p<.05). Symptoms of wrist pain and hand numbness in the daytime were common in the addiction group. There were statistically significant but poor positive relationships between the online game addiction scale and the SSS (r=.312, p<.01), and between the online game addiction scale and the FSS (r=.149, p<.01). The information about online game addiction and CTS identified in this study could contribute to the prevention of online game addiction and CTS in college students.

The purpose of this study was to know the correlation between the level of participating in badminton community activity - the period of participation, the intensity of participation, and the numbers of participation - and the sports addiction and eventua

In this study, microbial investigation is accomplished for 554 Jeot-kal samples (102 of Jeot-kal, 448 of Seasoned Jeot-kal and 4 of Sik-khe, respectively) that corresponds with Coliform-bacteria, Escherichia coli, Aerobic live bacteria as hygienic indicator microorganisms, and Staphylococcus aureus, Vibrio parahaemolyticus as Food-borne pathogenic microorganisms. Based on the methods in Korea Food Code, reliable data are obtained as follows; in 31.9% rate of the samples, Coliform bacteria are verified in the extent of 0~20,000 CFU/g as 2.3 logCFU/g. Especially, Seasoned Jeot-kal (37.7%, 2.3 logCFU/g) are detected to 6 and 2 folds higher than those of Jeot-kal, 5.9% and 1.4 logCFU/g. Likewise, Escherichia coli is detected from 9 samples only in Seasoned Jeot-kal, that includes seasoned squid, seasoned octopus, seasoned roe of pollack, seasoned large-eyed herring and seasoned hairtail. Aerobic live bacteria are also detected in the range of 0~8.9 × 108 CFU/g. Against salinity, E. coli are detected in samples only less than 10% salinity. Concomitantly, aerobic live bacteria count is decreased to 5.5~3.6 log CFU/g upon the salinity is increased up to 25%. However, S. aureus and V. parahaemolyticus are not detected in 554 samples, presumptively referring Jeot-kal products are somehow free from such food-borne pathogens. As the results above, we deliberately consider that the sanitary control in Jeot-kal, which be necessarily fermented- as well as non-microbially inactivated should be ensured in near future and also suggest an effectual microbial standard corresponding to the Negativity in E. coli for Jeot-kal products.

최근 우리 사회의 많은 관심 대상인 청소년 전자게임 중독 현황에 대하여 고찰하고, 이런 게임 중독으로 여러 사회문제를 야기 시켰다. 특히 우리 사회에서 거의 모든 청소년들은 게임을 즐기고 있다. (97.8%.게임백서 2006) 특히 한국사회에서 게임에 대한 본질적인 이해 부족으로 ‘청소년 게임 중독’에 대하여 학교나 가정에서 ‘억제’ 중심으로 접근하여 많은 갈등을 초래 하였다. 본 연구에서는 기존의 청소년 게임중독을 단순한 ‘차단’, ‘억제’ 중심인 ‘수동적’이고 ‘일방적’인 방법을 탈피하여 게임에 대한 올바른 이해와 교육을 통하여 우리의 미래인 청소년들에게 게임 중독에 대하여 ‘능동적’이고, 부모님과 선생님의 ‘상호작용’인 방법을 제안한다. 더욱이 우리사회의 전자게임 대한 인식이 ‘산업적’인 관점에서 탈피 하여 ‘문화적’인 매개로 접근을 제안한다. 전자게임 중독에 대한 예방 교육은 기존의 우리사회에서 전 자게임에 교육은 단순히 ‘게임인력 양성’중심에서 ‘게임 홍익인간 양성’으로 전자게임 에 대한 문화 교육의 제도화를 제안하여, 청소년 게임 중독에 대한 새로운 방안을 모색한다.

Rapid spread of the internet has made our everyday life more convenient, however it has brought some problems along with it. Especially, undergraduate student are losing their social ability as they become absorbed in the internet game, act selfishly in the cyber space and lose interest in studying. As a result, they become isolated from their friends and experience difficulty in the relationship with their parents. In this paper, the influence factors of internet game addiction is investigated using the Analytic Hierarchy Process (AHP) and statistics techniques. This study is to define the influence an important factors of internet game addiction using a questionnaire to internet game player and expert group. It is believed that this study will be more receptive to results that include the priority weights of internet game addiction among the addiction group, non-addiction group and expert group.

Even though South Korean criminal justice system felt the necessity of treatment and rehabilitation for the drug addicted inmates, South Korea has concentrated on the punishment of them while disregarding the treatment and rehabilitation. Therefore, drug addicted inmates go back to the prison without overcoming drug temptation. 「The policy for the rehabilitation of drug related offenders(2006. 5)」 which was released by the Korean Corrections Bureau of Ministry of Justice on May 2006 is an appropriate policy for the treatment and rehabilitation of drug addicted inmates. However, it is hard to achieve some practical results only if there is a lone effort by the department which is dealing with the drug addicted inmates. Now, there should be in-depth discussions among the drug offence related criminal justice system to achieve effective results. This study examines the current status of the management and treatment for the drug addicted inmates in the correctional facilities. Based on this examination, I would like to recommend some effective ways of management and treatment for the addicted inmates. Especially, this study will provide some additional considerations for the implementation of 「The policy for the rehabilitation of drug related offenders(2006. 5)」. This study presents following recommendations: First, drug addicted inmates should be classified and segregated from the stage of un-conviction to the release from prison. Second, there should be enough medical doctors and drug addiction professionals. We can use medical doctors who are majoring psychiatry instead of mandatory military service. For the drug addiction professionals, we can educate our drug related employees at the graduate programs in drug specialized universities. Third, there should be more programs and educations for the treatment and rehabilitation of drug addicted inmates. Fourth, through the periodical inspection of the inmates, the usage of drugs in the correctional facilities should be prevented. Fifth, we need to consider the concept of community correction for the drug addicted inmates. Therefore, we can build an intermediate prison for the addicted inmates or can give more parole opportunities. Also, by the alleviation of the closed treatments using the strict correctional and educational programs, we can use more open treatments.

본 연구는 식품을 오염시켜 식중독을 유발하는 주요 식중독 세균인 Escherichia, Salmonella, Shigella, Vibrio, Listeria 등 5속의 병원성 세균들을 반복성 염기성열을 이용한 ERIC-PCR을 이용하여 동시에 동정할 때 이용되는 주요 PCR 반응성분인 MgCl_2, dNTPs, primer, template DNA의 최적 농도를 결정하였다. MgCl_2 반응성분은 2 mM을 적용하였을 때부터 일정한 fingerprinting pattern을 얻을 수 있었으므로 2 mM을 MgCl_2의 최적농도로 결정하였다. dNTPs의 농도는 250 μM까지 증가함에 따라서 6균주 모두 200 μM까지는 농도 증가와 비례하여 단편의 수와 강도가 점증하였으나 그 이상의 농도에서는 단편의 수와 강도가 일정하였다. 그러므로 일정한 fingerprinting pattern을 얻기 위하여 200 μM의 dNTPs만으로도 충분하였다. ERIC primer들은 2 μM의 농도를 적용했을 때부터 일정한 fingerprinting pattern을 나타낼 수 있었으며, 그 이상의 농도를 적용했을 때 단지 단편들의 강도만이 증가하였다. Template DNA도 다른 PCR 반응성분에 대한 실험과 마찬가지로 적용한 DNA양의 증가에 따라 단편의 강도가 증가하였다. 그러나 대부분의 적용 균주들에 대하여 DNA의 양이 최소일 때와 최대일 때 각각의 얻어진 fingerprinting pattern들을 비교할 때 단편의 수는 별 차이가 없었다.
