Purpose: The purpose of the study was to·find the strategies of mental health screening in school. Based on the literature review, we discuss the importance of screening students in schools for mental health problems. Methods: Data from the 2008 Korean Mental Health Screening in Schools(2008-KMHSS) are used to estimate the outline of this screening. We administered the questionnaire for satisfaction of 2008-KMHSS for students(N=1,280), parents(N=2,672), school nurses(N=75), teachers(N=685), district personnels(N=6), and mental health center staffs(N=37). Also we interviewed a part of them by telephone and e-mail. And we reviewed the tools and methods for screening students for emotional/behavioral problems. Results: Mental health screening in schools is a very important, yet worrisome, agenda that is in its very early stages. From the 2008 Korean Mental Health Screening in Schools, 9,588 students(12.9%) needed more evaluation in the first stage. Of these, 6,910(72.1%) completed the second stage screening. In this sample, 1,975(28.6%) utilized the mental health services in school or community. 38.3% of students and 43.7% of their parents notified the2008-KMHSS. But only 12.1% of students and 10.9% of their parents dissatisfied with the screening. 9.9% of teachers and 22.7% of school nurses dissatisfied with the screening. Among them the school nurses were mostly dissatisfied, and they complained work burden from KMHSS. Mental health center staffs complained similar issues. The Children's Problem-behavior Screening Questionnaire(CPSQ) and Adolescents' Mental-health & Problem-behavior Screening Questionnaire(AMPQ) were compatible to screen students in schools for mental health problems in first stage. Conclusion: Mental health screening in schools needs careful planning and implementation. For successful mental health screening in schools, several elements need to be considered: careful planning, collaboration, staff training, and integrative mental health programs and services in community or schools.

멀티미디어 원격 회의 시스템에서의 정보 전송 시 음성, 영상, 데이터 등의 다양한 종류 및 특성의 멀티미디어 정보 전송이 필요하다. 이러한 다양한 특성의 정보 전송 기능을 제공하기 위해서는 통신망에서 전송 품질과 전송되는 정보의 종류에 따라 별도의 연결을 구성하여 각각 다르게 관리하는 것이 효율적이다. ATM(Asynchronous Transfer Mode) 통신망에서의 멀티미디어 원격 회의 정보 통신 서비스는 ATM계층에서 제공하는 multicasting기능 및 다중연결을 기반으로 다자간 통신 연결이 MP-to-MP 형태로 구성되며, 트랜스포트 프로토콜계층에서는 종단간 연결의 동기, 다중 연결 설정 및 해제, 다자간 연결 관리등의 기능을 수행하여야 한다. 본 논문에서는 각 미디어마다 개별 전송 채널을 사용하고, 다중 연결을 이용하여 다자간 통신이 가능한 멀티미디어/하이퍼미디어 트랜스포트 프로토콜의 계층 관리 기능을 분석하며, 그 구현 방안을 제시한다.

The purpose of this study was to evaluate effects of Cordyceps militaris on fat oxidation during submaximal exercise. Fifteen healthy male collegiate students(ingestion group, N=7; control group, N=8) participated as subjects after signing an informed consent following overnight, subjects completed maximal graded execise test on treadmill to determine exercise intensity(50%VO2max). To evaluate the fat oxidation using indirect calorimeter, it was performed submaximal treadmill to determine exercise lasting. 40min at 50%VO2max after 5day and consumed Cordyceps militaris on separate days. This study was used 2×4 two way repeated ANOVA to analyze physiological and metabolic variables between two groups and metabolic variables between two groups and four exercise periods(l0min, 20min, 30min 40min), and used Scheffe to post-hoc test. Significance was set at α=.05. The results of this study were as followed: First, there were significantly highest in ingestion group for V02, percentage of fat oxidetion(%fat), fat per kilocarolies(Fkcal), and total per kilocarolies(Tkcal)(p<.05), but respiratory exchange ration(RER) and heart rete(HR) were significantly lower in ingestion group(p<.05). Second, RER, %fat, Fkcal were significantly difference in 10, 20, 30, 40min of exercise period(p<.05). This results suggest that there is the effect of Cordyceps militaris on fat oxidation submaximal exercise. Additionally, to evaluate effect of Cordyceps militaris as ergogenic aid, it should be required the future study that included extend subjects, various dosage, and chronic consumption.

전이온도가 72K인 고온초전도체 Y?P?B?Cu?O?에서 초전도성을 감소시키는 Pr원소자리에 Ca과 Zn를 적당히 치환시켜 자기적 성질을 연구하였다. 초전도 전이온도(Tc)는 Ca이 치환된 시료의 경우 80~85k의 범위에서 측정되었으며, Zn가 치환된 경우에는 35~49K의 값을 보였다. 비저항의 온도 변화로부터 결정된 전기적 전이온도는 온도에 대한 자기모우먼트으 변화에서 구한 자기적 전이온도와 비슷한 값을 보였다. 자기이력곡선으로부터 Bean의 모델을 이용하여 Hcl(저임계자기장), Hc?(고임계자기장), 반자성정도, 임계전류밀도를 측정하였다. 이러한 성질들은 시료 내에 Ca의 치환량이 많아질수록 증가하였으며, Zn가 많아질수록 급격히 감소하였다. 특히 임계전류밀도는 x=0.0인 시료는 1.60x10?A/㎠이었으며 Ca이 치환된 시료는 1.30~1.98x10? A/㎠, Zn가 첨가된 시료는 3.5x10?~1.3x10?A/㎠의 값으로 계산되었다. 이것은 시료 내에서 Ca은 초전도성을 증가시키고, Zn는 초전도성을 감소시키는 것을 의미한다. We have studied magnetic properties as a appropriate substitute of Ca and Zn element for Prelement which reduces superconducting properties in the high-temperature superconductor Y?Pr?Ba?Cu?O? of transition temperature 72K. When Ca is put into, the critical temperature(Tc)showed the value of measurement at the range of 80~85K while for Zn the Tc had the range of 35~49K. The electric critical temperature determined by the temperature dependence of resistivity had a similar data to the magnetic field), Hc?(high critical magnetic field), diamagnetic ratio and critical current density have observed by Bean's model from the magnetic hysterisis curve. These properties were increased with adding Ca and abruptly decreased with adding Zn in the samples. Especially, the critical current density of x=0.0 sample was calculated at 1.60x10?A/㎠ and those of the other Ca-added samples at the range of 1.30~1.98xA/㎠and those of Zn-added samples at the range of 3.50x10?~1.30x10?A/㎠. These mean that Ca increases supercondecting properties in the sample and Zn element decreases them.

It was reported recently that ciliary neurotrophic factor (CNTF) is mainly present in the Schwann cells and asrocytes and maintain the motor neurons in postnatal periods. But there is no detailed research about the localization of CNTF. Several articles showed that there were many regions which have CNTF positive neurons. To test the unsettled CNTF immunoreactivity, the immunohistochemistry with CNTF antibody (Research & Development of the BML, Japan) was performed in th erat brain. The adult female rats weighing aound 200g were fixed by perfusion and 40-㎛-thick frozen sections were taken, and perform CNTF immunohistochemistry. The CNTF immunoreactivity was observed in the astrocytes of the optic nerve, olfactory nerve, fimbriae of the hippocampus, internal capsule, and cingulum, and in the non-astrocytes of the pyramidal tracts, the ventral portion of the pontine nucleus, and the central portion of the medulla oblongata. These data show that CNTF immunoreactivities present mainly in the astrocytes between the nerve fiber bundles in the cerebrum and in the non-astrocytes of the brain stem.

In order to investigate to develop the new dosage form of the traditional herbal medicine which have been used for the treatment of disease in oriental medicine, we conducted a survey on 217 patients who visited oriental hospital in Kyung Hee University Medical Centre during one month since October 2003. They were given questionnaires to answer and results of this study were as the following: 1. About 45% patients visited in oriental hospital believed that oriental medicine was better remedy than modern medicine. 2. Most of patients felt that the oriental medical expenses were expensive. 3. About 60% patients preferred the modernized dosage form such as extract powder and granule, etc. rather than medicinal herbs in package. 4. Most of patients hope that decoction of medicinal herbs in package would change the advanced dosage forms such as tablet, capsule and extract powder, Because patients suffered from inconvenience of making a decoction, unhandy, unwieldy and keeping. 5. About 60% patients pointed out that merits of advanced dosage forms of medicinal herbs were convience to take and handy, etc.. However, they had an Intension that there were some difference of efficacy between decoction and modernized dosage forms of oriental medicine. Because of several defects such as unusual flavor and smell, incompatible food, large volume with amount, inconvenience of carrying and decocting oriental herbal medicines, most of patients would expect the development of the advanced dosage forms of them. In summary, this study show that it was needed to develop the new dosage forms of oriental herbal medicine on the basis of scientific research and economical cost of medical expenses.
