Objectives : The purpose of this study was to establish an accurate and effective method of locating acupoints of the forearm by studying bone proportional measurement. Methods : A total of 60 volunteers, 30 men and 30 women, participated in this study. 7 parts of the body were measured by a soft ruler or digital vernier calipers. The cun of the upper limb was calculated and analyzed. And the results were compared with the standard cun. Results : The bone proportional cun of the forearm based on height and femur was close to 11. It was different from the standard 12.5, 12 or 10. The cun of the forearm by thumb or finger width measurement was different from the standard too. Conclusions : We suggest that locating acupoints of the forearm needs to be done based on 11 cun. The confusion on locating acupoints of the forearm will be reduced by reflecting the result of the actual measurement.

Objective This study aimed to analyze the efficacy and safety of Tuina therapy for attention-deficit hyperactivity disorder (ADHD) through a randomized controlled clinical study in China. Methods We used the China National Knowledge Infrastructure (CNKI) as a resource and conducted a search using key words: 'ADHD', '推拿'. Six randomized control studies were identified and analyzed in this study. Results 1. The Tuina treatment group showed significant changes compared to the control group. 2. The most commonly used meridians were Spleen meridian (脾經穴), Liver meridian (肝經穴), Errenshangma (二人上馬穴), Xiaotianxin (小天心), Qinghetianshu (清河天水), Kidney meridian (腎經穴). Conclusions The results of this study showed that Tuina therapy is effective for ADHD patients with ADHD. It can be used for future research on Tuina therapy for ADHD.

본 논문에서는 효율적인 환자 이송 및 치료를 위한 응급구조사와 의료기관 간의 의사소통 및 질 관리를 위한 EC&M (Efficient Communication and Management) 시스템을 제안한다. 이는 관련 앱을 효율적으로 사용하여 응급차 배치부터 병원 도착 시 환자 수속 작업 등을 최소화하고, 각 작업의 수행시간을 최소화 한다. 또한 이 시스템의 사용자는 소방청, 의료기관, 119 응급 구조사이고, 이 중 응급구조사에 초점을 두었다. 이는 PRE-KTAS를 소방청과 의료기관에 동시전달하여 전달된 PRE-KTAS를 통한 적절한 의료기관을 배치하고 선정된 응급의학 전문의에게 직접의료지도를 요청할 수 있다. 그리고 응급구조사는 의무기록활동지를 작성하여 의료기관에 전달하여 내용전달의 효율성을 높인다. 본 논문에서는 시뮬레이션을 통하여 제안하는 응급구조사와 의료기관 간의 정보 공유 시스템은 기존에 제안하는 앱을 사용하지 않고 발생했던 많은 문제를 해결 할 수 있을 것이므로 기존의 앱보다 우수할 것으로 기대된다.

The purpose of this study was to provide basic data to establish MICE(meeting, incentive, convention, exhibition) marketing strategies in Busan Metropolitan by examining its satisfaction level. Surveys were conducted for participants of 10 cases of Meetings, Incentive, Conventions and Exhibition in Busan Metropolitan. A time series analysis was performed by its data from 2002 to 2008. Research findings showed that accomodations, facilities and MICE operation were highly scored, while connected tour, shopping, easy access to airport, and interpretation were scored relatively low. Especially connected tour was scored very low. Therefore, we should concentrate on tourism attractions and tourism information services to improve visitors satisfactions. Second, we should develop shopping items to improve satisfactions of MICE visitors. Since this study only targeted the 10 MICEs they cannot represent the entire MICEs in Busan and absolute comparison was difficult because of different content and size of each MICE, which could be the limitation of this study.

Streptococcus iniae is a typical fish pathogen causing streptococcosis and it can also cause zoonotic infectious diseases. We studied S. iniae FP5228 isolated from infected olive flounder in Wando, Korea. In a study to find virulence factors in FP5228, we found that the number of live bacteria decreased dramatically in culture medium containing S. iniae FP5228 for more than 24 hr. This phenomenon was hypothesized to be related to Toxin ${\zeta}$ and Antitoxin ${\varepsilon}$ genes, components of the Toxin/ Antitoxin (TA) system on the 14 kb plasmid of FP5228. We used a protein overexpression system to identify it. The pBP1140 vector system was constructed to regulate the expression of Toxin ${\zeta}$ and Antitoxin ${\varepsilon}$ by IPTG and Arabinose. E. coli/pBP1140 strain grew slowly in early growth under toxin expression condition, and it was confirmed by microscopic observation that the strain became longer. S. iniae CK287, lacking a 14 kb plasmid of S. iniae FP5228 strain, was constructed. CK287 bacterial cells did not show rapid killing during culture, and the ability to produce biofilm was also decreased, and toxicity was weakened in cytotoxicity test and fish test. These results suggest that the TA system is involved in physiological regulation and expression of virulence factors in S. iniae FP5228.

해수면 상승의 예측에 대한 근본적인 불확실성은 전 지구적 해수면 상승에 대한 가속도와 상대적으로 해수면에 영향을 미치는 지역적인 요소와 연관되어 있다. 최근, 기후 모형을 포함하는 다양한 모형의 결과와 빙하 관측자료, 그리고 이들의 해수면에 대한 기여도는 해수면 상승이 가속화될 것이라는 사실을 나타내지만, 아직 조수 관측과 위성 자료들은 이와 관련된 근거를 발견하지 못하고 있다. 본 논문에서는 연안도시 계획 설계자들이 이러한 해수면 상승의 불확실성을 고려할 수 있도록 미래 해수면 상승의 확률론적 산정을 제공하기 위해 최근 해수면 상승 가속과 그 상승률에 대해 선택된 분포와 관측 해수면 자료의 합성을 제시한다. 결과는 프로젝트 취약성을 평가하기 위한 위험도 기반 관리체계의 기준으로서 사용 될 수 있다. 또한, 기후 영향에 의한 해수면의 동역학적 지질물리학의 이해도를 증진시킴으로써, 분포의 선택과 정확성, 그리고 해수면 상승 예측이 개선될 것이라고 기대 된다. 본 연구에서 제시된 방법론은 사례연구로 부산에 적용되어 설명되어 진다.

기후변화로 인해 지구의 평균 해수면이 상승하고 그에 따라 연안지역의 피해가 증가함에 따라 해수면의 상승이 연안지역에 미치는 영향을 알아보고자 사면이 바다와 접한 부산의 영도지역을 구체적인 대상으로 선정, 해수면 상승 영향에 따라 해수면을 평행단면으로 하여 상승 시 침수범위와 재해위험지역을 종합적으로 고려, 피해 예상지역 추출하고 침수취약지역을 그 침수특성 및 지역특성에 따라 세부적인 침수구역으로 구분하고 침수구역별로 자세한 침수대책을 마련한다.

Objectives : Some studies have reported that chronotypes, among several factors, could contribute to problematic drinking. However, there is little evidence confirming this relationship between chronotype and problematic drinking based on gender differences in mood disorder. This study is to investigate the difference of the relationship between chronotype and problematic drinking according to gender differences in mood disorder. Methods : Two hundred fifteen patients with mood disorder were recruited. Problematic drinking and chronotypes were assessed by the Alcohol Use Disorder Identification Test in Korea(AUDIT) and the Korean translation of composite scale of morningness(KtCS). We analyzed the correlation between KtCS and AUDIT using Pearson's correlation, and compared AUDIT scores according to chronotypes classified by KtCS between male and female patients using analysis of variance(ANOVA). Results : There was no significant difference in AUDIT scores between the male and female patients(t=0.91, p=0.183). In female patients, eveningness had significantly higher AUDIT scores than other chronotypes(F=0.199, p=0.033). Meanwhile, in male patients, there was no significant difference in AUDIT score among chronotypes(F=0.008, p=0.933). Conclusion : This study suggests that eveningness might be associated with problematic drinking in female patients who suffer from mood disorder. It also suggests that chronotherapeutical treatment might be able to help improve the course in female patients with mood disorder. In the future, a large-scale prospective study is needed to confirm these results.

A new quantitative analytical method has been established for the rapid determination of flumethrin in honey products using high performance liquid chromatography (HPLC). Sample was dissolved and extracted in the mixture of water and acetonitrile (1:2). The extracts were purified with silica cartridge eluted by the mixture of hexane and dichloromethane (55:45) and analyzed at 266 nm using HPLC. The percentage recovery of flumethrin spiked in sample was found to be 90.2-97.8% and the limit of detection is 0.003 mg/kg. We validated the method for the linearity, the precision and the reproducibility. We investigated the residues of flumethrin in honey products retailed in market using the established method. Flumethrin was not detected at all among 130 samples of honey.
