Purpose: This study aimed to recognize the frequency of near-hanging patients with elevated Troponin-I (Tn-I), to obtain information necessary for treatment and prediction of prognosis by analyzing the clinical feature of near-hanging patients, and to evaluate the relevance of elevated Tn-I to abnormal result of other cardiac-related examinations. Methods: A retrospective review for the near-hanging patients, clinical record was conducted at two urban training hospitals between April, 2001 and December, 2011. We divided included patients into two groups, which one with elevated Tn-I level ($Tn-I{\geq}0.1ng/dL$) and one without it, and compared the differences in initial vital signs, cardiac enzyme tests, an electrocardiogram, echocardiography, chest X-ray, and the clinical outcomes. Results: A total of 39 patients were included, out of them, 14 patients showed rise in Tn-I level. The length of hospital stay and ICU hospitalization was more prolonged in the patient group with elevated Tn-I level than non-elevated group. As well as the incidence of endotracheal intubation and abnormal findings in echocardiography or chest X-ray was higher in the Tn-I elevated group, which is statistically significant. Conclusion: The rising of serum Tn-I level in near-hanging patients were not uncommonly observed. We believe that the cardiac-related test including Tn-I is necessary for near-hanging patients, and those who are shown abnormal result in cardiac-related test may need close observation and intensive care.

The aim of the study was the application of Radix Aconiti(附子) in the treatment of heart-systemic disease(心系疾患). We inquired into the prescriptions with Radix Aconiti (附子) in the treatment of heart-systemic disease(心系疾患) in many other aspects through 'Sanghanron'(傷寒論). The results were obtained as follows; The prescriptions with Radix Aconiti(附子) form about 18%, it's related text forms about 11%. Radix Aconiti(附子) was used with other 20 kinds of herbs in 7 categories-hyepyo(解表), jesp(除濕), selyul(泄熱), hwagihyengsu(化氣行水), onjungsanhan(溫中散寒), ikum(益陰), anhejitong(安蛔止痛). Among these herbs, the combination with Zingiver officinale Roscoe(乾薑) is focal usage, because the combination was used in 8 prescriptions out of 20. A fresh Radix Aconiti(附子) which was used with Zingiver officinale Roscoe(乾薑) is efficacious against poison of Radix Aconiti(附子). When this combination was used, it had been boiled for a long time in most cases, it is also helpful of counteracting poison. A Steamed Radix Aconiti(附子) was used with Zingiver officinale Roscoe (生薑). In the special feature of dosage of Radix Aconiti(附子), it was considerately used in many different conditions which includes strength or weakness of patients, and the critical or slight condition of illness. In the taking frequency and dosage of the medicine, it was applied the same. There are 2 methods of boiling, one is boiling separately from other herbs and the other is boiling all together. When boiling seperately, it works more quikly and strongly. In the case of severe 'rehan'(裏寒) which refuses warmed medicine, it was used with 2 other herbs(猪膽汁, 人尿) that take down from yang(陽) to ying(陰). The foci of prescriptions that contain Radix Aconiti(附子) is the type of Sayektang(四逆湯類), because Gungangbujatang(乾薑附子湯) does the important work in the prescriptions. The paradigm of Radix Aconiti(附子) treated palpitation, edema, diziness, confusion, numbness, iced limbs in the treatment of heart-systemic disease(心系疾患). In the usage of Radix Aconiti(附子), the above results need to be referred and further clinical studies will be necessary.

Arranging 63 kinds of separate volumes and papers published on Oriental medicine, I could get the result as follows. 1. The herbs for internal application used commonly in vitiligo are 155 kinds totally. The herbs for external application are 67 kinds. The herbs for external and internal both application examined into 23 sorts. 2. Herbs for weakness syndrome in vitiligo are 49 kinds. Another type, excess syndrome is 105 sorts, the'latter is roughly twice as many as the former. 3. It is as follows that the results of study in relations to kinds, factors, and medical treatments of herbs about vitiligo in and out of the country with the division of former times to 1900, 1901 to 1980, 1981 to 1990, and 1991 to the latest day. In comparative study of inner and outer of thc country about factors and medical treatments of vitiligo in chronicle classification, its factors in the internal documents are classified by outside factors. Although there arc the differences of factors by each epoch, however, the factors of vitiligo according to external documents are blood stasis(血熱), deficiency of um of the liver and kidneys(肝腎陰虛), deficiency of blood(血虛), excess of exhaustion(勞倦過多) etc. Moreover, the medical treatment is more diverse and the differences by each epoch as to the medical treatment is also put down more saliantiy than in internal documents. 4. In comparison with herbs in experimental and no experimental documents, herbs applied for weakness syndromes in experimental method are 40 kinds totally. The herbs in no experimental methods are 35 kinds. The herbs used by experimental method are 65 kinds. The common herbs for excess syndrome by no experimental method are 78 kinds. We can see comparable difference from kinds of herbs used by experimental method. In brief, there are the differences classified by each epoch in Oriental medicine for treatment. Especially one of the most important feature, the frequency in use of weakness syndrome herbs has increased more than that of excess syndrome herbs. In external documents (china) and experimental study, generally the differences of common herbs and factors have disappeared through many experimentsitudy. The classification of its factors have been fractionalized clinically. Besides, in Western medicine and Orienal medicine, vitiligo tends to be prescribed not to simple skin disease but a mental and physical disease, a whole body and an internal disease.

The emotion plays a critical role in human's daily life including learning, action, decision and communication. In this paper, emotion discrimination classifier is designed to reduce system complexity through reduced selection of dominant features from biosignals. The photoplethysmography(PPG), skin temperature, skin conductance, fontal and parietal electroencephalography(EEG) signals were measured during 4 types of movie watching associated with the induction of neutral, sad, fear joy emotions. The genetic algorithm with support vector machine(SVM) based fitness function was designed to determine dominant features among 24 parameters extracted from measured biosignals. It shows maximum classification accuracy of 96.4%, which is 17% higher than that of SVM alone. The minimum error features selected are the mean and NN50 of heart rate variability from PPG signal, the mean of PPG induced pulse transit time, the mean of skin resistance, and ${\delta}$ and ${\beta}$ frequency band powers of parietal EEG. The combination of parietal EEG, PPG, and skin resistance is recommendable in high accuracy instrumentation, while the combinational use of PPG and skin conductance(79% accuracy) is affordable in simplified instrumentation.

The purpose of this article was to get hold of adolescent's needs for sex knowledge and to reveal their understanding of sex. These results may be applied to the sex education and counselling for adolescent. The participants of study were 267 students (females, 144 ; males, 123) who were the first and second grade form 1 middle and 2 high schools. They were asked to describe 3 questions that they wanted to know or to learn about sex. Their questions about sex were total 779(girls, subtotal 456, mean 3.2, boys, subtotal 323, mean, 2.6). These questions categorized to 9 items by content analysis. The items were ‘sexual drive, behavior and tendency(229, 29.4%)’ , ‘anatomy and physiology of reproductive system(140, 18.0%)’, ‘reproduction(131, 16.8%)’, ‘concept of sex(31, 4.0%)’, ‘acquaintance between the other sexes(17, 2.2%)’, and ‘the others(9, 1.2%)’ in order of frequency. The most frequent item that the student want to know or team about sex was ‘sexual drive, behavior and tendency’ except girls of sophomore in middle school. There were several features in participants' needs for sex knowledge as respects of the understanding of sex- biological sex, gender, and sexuality. The prominent feature in knowledge need of bio logical sex was that the participants had the interests according to their biological sex. They had the negative attitude to the phenomenons (ex, menstruation and pregnancy, phimosiectomy, etc) that they experienced or would experience due to their biological sex. A part of them asked the questions based the misconceptions and used the slangs or ‘××’, ect. to name the male or female genitalia. The male students wanted to know the female genitalia. The participants' understanding of gender reflected the sexism of our society, but they didn't accept and had doubts about the dual, hierarchical structure of that. The students, especially female seemed to be powerless to the harms of the sexual violence. Girls had much interest in their appearances and complained to our sexual culture that women comforted and served men. The participants had the dual perspective that the sexuality as respects of physiologic phenomenon was considered as natural but that as related to heterosexuals was as negative. And they deemed that men's sexual drive was stronger than women's and was difficult or was not able to be inhibited. They had much interests in homosexuality but reflected the negative attitude to that in our society. Adolescent felt wonder why the expressions of sexuality of adult were permitted but theirs were not. Lastly, a part of boys substituted querying the sexuality of animals for asking that of human. Maybe it was because of the embarrassment to talk about human's sexuality directly. The teenaged participants understood that the sex had not only the biological meanings but also the sociocultural meanings. They regarded the sex as natural and wanted to know it, but they had conceptions that it was difficult and embarrass to talk about it openly and directly.

Polymer substrates were fabricated by using poly (phenylene ether) as a base resin, N,N'-m-phenylenedimaleimide (PDMI) as a crosslinking agent and decabromodiphenylethane as a flame retardant. The effects of crosslinking agent and flame retardant on physical properties such as dielectric property of the substrate were investigated. Thermal curing feature of PDMI with or without an initiator was analyzed by DSC, and then, PPE-PDMI test compositions were designed based on this result. Composite sheets were cast by film coater, laminated under vacuum and pressure, and then, the changes of dielectric constant, dielectric loss, peel strength, solder heat resistance and inflammability according to increasing amount of PDMI and flame retardant were evaluated, Dielectric constant and dielectric loss showed increasing trend with increasing amount of PDMI and flame retardant, but solder heat resistance and inflammability were improved. Peel strength was obtained higher than 1 kN/m when PDMI above 10 wt% was added, but slightly decreased as the amount of flame retardant increased. From the measured gel contents, the reaction mechanism of PPE-PDMI system was deduced to the formation of network structure by crosslinking PDMI with PPE rather than the formation of semi-IPN structure. In conclusion, the polymer composite substrate materials with dielectric constant of 2.52$\sim$2.65 and dielectric loss below 0.002 at 1 GHz were obtained and they will be proper for high frequency applications.

Insomuch as it is important to manage water quality, from the perspective of water management, it is essential to understand the effect of the weirs on water quality and phytoplankton dynamics in various regions. The purpose of this study is to investigate the characteristics of nitro-nutrients, as well as occurrences and succession patterns of phytoplankton, in the river sections of the two weirs in the Yeongsan River for the five years (from 2012 to 2016) after the weir construction. In respect to this data, the average water temperature measured at the representative point in the section of the Seungchon Weir ($17.1^{\circ}C$) was higher than that of the Juksan Weir ($16.6^{\circ}C$) by comparison. By way of an analysis of this data, it was found that the water quality variables such as, organic matter, nitrogen nutrients and phosphorus nutrients were improved gradually during the period, but the degree of the improvement differs as noted and measured between the weirs. Under the circumstances, it is especially noted that the $NH_3-N$ concentration was higher for the point of the Seungchon Weir (2.204 mg/L) than that of the Juksan Weir (1.157 mg/L). This indicates that effluent as seen from sewage treatment plants and hydrological feature near the densely population area, could be the main cause for the incidence of water pollution in the upstream section of the Seungchon Weir. Additionally, the phytoplankton analysis showed that a relative abundance of diatoms and green algae were 56.9 % and 25.8 % respectively. However, it is noted that the cyanobacteria was measured lower as 10.7 %. Also, in the study sites cell density and occurrence frequency of cyanobacteria were relatively lower than compared to the same measurements noted in other rivers.

Due to rapid development of bioinformatics technologies, various biological data have been produced in silico. So now days complicated and large scale biodata are used to accomplish requirement of researcher. Developing visualization and annotation tool using them is still hot issues although those have been studied for a decade. However, diversity and various requirements of users make us hard to develop general purpose tool. In this paper, I propose a novel system, Genome Viewer and Annotation tool (GenoVA), to annotate and visualize among genomes using known information and multiple relation graph. There are several multiple alignment tools but they lose conserved area for complexity of its constrains. The GenoVA extracts all associated information between all pair genomes by extending pairwise alignment. High frequency conserved area and high BLAST score make a block node of relation graph. To represent multiple relation graph, the system connects among associated block nodes. Also the system shows the known information, COG, gene and hierarchical path of block node. In this case, the system can annotates missed area and unknown gene by navigating the special block node's clustering. I experimented ten bacteria genomes for extracting the feature to visualize and annotate among them. GenoVA also supports simple and rough computational annotation of new genome.
