Backgroud: There are well-known problems in the management of low weight neonates or infants with congenital heart defects. In the past, because of a perceived high risk of operations using cardiopulmonary bypass(CPB) in these patients, there was a tendency for staged palliation without the use of CPB. However, the recent trend has been toward early reparative surgery using CPB, with acceptable mortality and good long-term survival. Therefore we reviewed our results of the operations in infants weighing less than 3kg and considered the technical aspect of conducting the CPB including myocardial protection. Material and Method: Between Jan. 1995 and Jul. 1998, 28 infants weighing less than 3kg underwent open heart surgery for many cardiac anomalies with a mean body weight of 2.7kg(range; 1.9-3.0kg) and a mean age of 41days(range; 4-110days). Preoperative management in the intensive care unit was needed in 20 infants and preoperative ventilator support therapy in 11. Total correction was performed in 23 infants and the palliative procedure in 5. Total circulatory arrest was needed in 11 infants(39%). Result: There were seven hospital deaths(25%) caused by myocardial failure(n=3), surgical failure(n=2), multiorgan failure(n=1), and sudden death(n=1). The median duration of hospital stay and intensive care unit stay were 13days(range; 6-93days) and 6days(range; 2-77days) respectively. The follow-up was achieved in 21 patients and showed three cases of late mortality(15%) and a one-year survival rate of 62%. No neurologic complications such as clinical seizure and intracranial bleeding were noticed immediately after surgery and during follow-up. Conclusion: The early and late mortality rate of open heart surgery in our infants weighing less than 3 kg stood relatively high, but the improved outcomes are expected by means of the delicate conduct of cardiopulmonary bypass including myocardial protection as well as the adequate perioperative management. Also, the longer follow-up for the neurologic development and complications are needed in infants undergoing circulatory arrest and continuous low flow CPB.

In order to investigate the influence of sea condition on the catch fluctuation of long line for common octopus, octopus variabilis, the oceanographic factors, i. e., the wind direction, the wind speed, the age of moon and ebb tide and flood tide in the coastal waters of Yosu from Jan. 11 to Jul. 25 in 1997, and compared with the catches of common octopus, octopus variabilis, by long line. The results obtained summerized as follows; 1) The catch of common octopus was highest in wind direction from SE and lowest in that from NW. The catch was highest at the wind speed of 2m/sec and decreased with increasing speed, over 2m/sec. 2) The catch of common octopus was highest at the day of neap tide and lowest at the mid day, from neap tide to spring tide. More strictly the catch was higher during days at which the current became rapid than during days at which the current became slow. The catch was higher always at flood tide than at ebb tide in all the days investigated and highest with in one hour from ebb tide.

After individual consumption tax on bituminous coal has been imposed by Korean government after 2014 Jul, we analyse the influence of tax and conclude that the consumption of high calorie coal has been increased and that of low/middle calorie coal has been decreased. And also, the average calorie of coal consumption has been increased and the more fuel cost happens on account of the average calorie increase. Those effects have been caused by the current tax imposition system which does not reflect the bituminous coal trait. The motivation of oversea resource development and the effort of coal blending skill have been decreased because of the current tax policy. We suggest 2 ways of the tax policy improvement system[1. tax imposition system in proportion to 5,000kcal/kg, 2. 15 stages(1 stage : 200kcal/kg) segmentation tax imposition system equal to the tax/(5,000kcal/kg)] to increase the current tax amount, to prevent the coal consumption distortion and to remove the further fuel cost.

Background and Objectives: $Radiesse^{(R)}$ is a gell-formed material of calcium hydroxylapatite (CaHA) and carboxymethylcellulose (CMC) used for vocal fold injections. The authors aimed to study injection laryngoplasty with $Radiesse^{(R)}$, and determine the efficacy of $Radiesse^{(R)}$ for unilateral vocal cord palsy using objective and subjective measures. Materials and Method: Nine patients with unilateral vocal cord palsy received injection laryngoplasty with $Radiesse^{(R)}$ under general anesthesia from Jul. 2007 to Jan. 2008. $Radiesse^{(R)}$ was injected with 25gauze long needle perorally or percutaneously. The Acoustic, aerodynamic, stroboscopic analysis and pre-injection/post-injection perceptual assessment were evaluated in all patients. Results: Postoperative jitter and shimmer scores tended to diminish compared to preoperative scores, and maximum phonation time increased with statistical significantly. Stroboscopic findings demonstrated improvement postoperatively. The degree of hoarseness, which is a part of perceptual assessment, decreased after the procedure. Conclusion: $Radiesse^{(R)}$ may be an altemative material for injection laryngoplasty. We suggest long-term follow up with more cases.

This study was conducted to provide basic data for optimal fisheries management through the accurate understanding the catches, fishing level, species composition, distribution characteristics and fisheries status of trammel net in Gangwon Province. As the results of trammel net survey, Pisces were collected 77 species, 1,983.0 kg, Crustacea 9 species, 569.0 kg, Cephalopoda 5 species, 75.3 kg, Gastropoda 12 species, 16.5 kg in the coastal waters of Sokcho and Pisces 55 species, 3,681.5 kg, Crustacea 6 species, 2,229.8 kg, Gastropoda 10 species, 72.8 kg, Cephalopoda 4 species, 10.1 kg in the coastal waters of Donghae, respectively. The catches of important species with season and depths showed that the main target species is Pleuronectidae spp. at all depth and Aptocyclus ventricosus at <100 m in Sokcho, Liparis spp. and Dasycottus setiger at 200-500 m in Donghae, respectively. The mean total length (cm) of Gadus macrocephalus and Aptocyclus ventricosus didn't appear significant difference, but the mean total length of Pleuronectidae spp., Liparis spp. and D. setiger in Donghae is bigger than in Sokcho. From the cluster and MDS analysis based on Bray-Curtis similarity matrix of fourth root transformed, catches data of dominant species in the coastal waters of Sokcho and Donghae was divided into three different groups of the demersal organisms community in 12 survey of Donghae (Group A) and Jul., Oct.-Dec. survey of Sokcho (Group B) and Jan.-Jun. and Aug.-Sep. survey of Sokcho (Group C).

Purpose: The purpose of this study was to seek ways to improve the quality of life of workers by separating workers into the low fatigue group and the severe fatigue group depending on the level of fatigue level, and analyzing and understanding the difference between quality of life and job stress according to the fatigue level. Methods: For the 'Development of Mibyeong management system which was a consumer-directed health care service', the data of job stress, fatigue and quality of life was collected from 115 workers who visited the oriental hospitals located in J city and C city from Jul, 2012 to Dec, 2012. Results: The severe fatigue group showed significantly higher job stress than the low fatigue group in physical environment (p=.004), job demand (p<.001), interpersonal conflict (p=.012), lack of reward (p=.062). The severe fatigue group showed lower degrees both in physical component summary (PCS) (p<.001) and mental component summary (MCS) (p<.001) measured by SF-12 and the quality of life (p<.001) measured by EQ5D than the lower fatigue group. A relatively strong negative correlation was found in the item of mental component summary (MCS) measured by SF-12. Conclusion: Considering our results that high fatigue level show negative impact on quality of life and job stress, we suggest to provide a variety of health promotion strategies to improve the quality of life through the prevention and relief of fatigue for workers.

Purpose: This study is a descriptive research in which the pathological syndromes of the schizophrenic patients in the community mental health centers, the degrees of the insights, and the correlations between them were examined. Method: The subjects included 114 SPR pt. people who were enrolled in community mental health centers located in D City. The research was conducted during the period from Aug. 1st, 2002 to Jul. 30th, 2004. The instruments were PANSS developed by Kay(1987) and SUMD developed by Amador(1993). Results: Among the pathological syndromes, positives ones were $12.64{\pm}3.80$ on the average, negative ones were $32.00{\pm}5.36$, and general pathological syndromes were $30.50{\pm}6.24$. In the evaluation of the insights, the mean score was $11.81{\pm}5.09$. There were some significant correlations between positive syndromes and general pathological ones (r=.572, p=.000), and negative syndromes and general pathological ones(r=.262, p=.029), while there was no significant correlation between the insights and the sub-measures of general pathological syndromes. Conclusion: Therefore, the schizophrenic patients taking advantage of the community mental health centers have more negative syndromes than those in hospitalized, and rehabilitation programs are needed to help them continuously. And the further study of the correlations between the pathological syndromes and the degrees of the insights are required, and still, it should be analyzed what effects the insight acquirement brings about to the improvements of the pathological syndromes after the application of the insight-oriented programs.

The objective of this article is to induce that the conception of 'Qi-jul(氣質) and Qi-pum(氣稟)' was introduced to the Sasang(四象) Constitutional Medicine from bibliographic study on the theory of 'Qi-pum(氣稟)'. The conclusions summerized as followings. 1. In the oriental medicine, qualitative difference of 'zheng-qi(正氣)' among the individuals, the opposing power against a disease, is regarded as constitution. Having been used as 'nature(素)', 'quality(質)' and 'character(氣質)' in the oriental medical book, the word of 'Che-Jil(體質)' was used in good earnest at the end of 'Qing(情)' dynasty. 2. The nature(性) is divided into two, original nature(本然之性) and charicteristic nature(氣質之性) in the 'New confucianism(新儒學)' and the former means a principle(理), is a pure and good thing and used as a conception of universality, the latter is a principle of character and a imperfect imitation of principle(理). 3. It was repeatedly confirmed that 'Qi-jil and Qi-pum' meant the difference among the individuals by the dispute of 'Li-Qi(理氣)' caused by Lee Hwang(李滉) and Lee Yi(李耳) and by that of 'Ho-Rak(湖洛)' in the Ch'o-son(朝鮮) dynasty. 4. Han Sok-Ji, based on Meng-Zi(孟子)'s doctrine that man's inborn nature is good, criticized the theory of 'Qi-pum' which was 'Zhu-Zi(朱子)'s opinion and his opinion about the life(命) was thought to clue to the classification of the 'Sasang(四象)' invented by Lee Je-Ma as Park Se-Dang's theory that everyone has common nature but has different life(命). 5. By introducing the theory of 'Qi-pum' and the conception of life(命) which was understood as a special character by Han Sok-Ji and Park Se-Dang to Sa-sang constitutional medicine, Lee Je-Ma explained the reason why each man who was classified four constitutions, 'Taiyang'(太陽), 'Taiyin'(太陰), 'Shaoyang'(少陽), 'Shaoyin'(少陰), had the different formation of the visceral department(臟局).

Objectives In this research, the constitutional diagnosis based on the theory of Sasang constitutions were carried out to Japanese subjects living in Japan, and the external applicability of Sasang constitutional medicine was evaluated by analyzing the physiological symptoms and the pathological symptoms according to their constitutions. Methods Total 144 Japanese subjects who live in S city were invited from Mar. 2010 to Jul. 2011 for the research, and their constitutions were analyzed with constitution diagnosing tool that was developed by Korean institution of oriental medicine (KIOM) in 2011. The collected data was analyzed in terms of the physiological symptoms and the pathological symptoms according to the sasang constitutions with computer software of SPSS 17.0. Results In the physiological symptoms related to excrements, Soyangin more frequently did not have excrements of gold color (p=.034) and feel the tenesmus (p=.047) than the subjects of other constitutions. In the physiological symptoms related to cold & heat, Soyangin more frequently felt cold in feet and hands (p=.011), and Soeumin more frequently didn't like drinking water regardless of thirst (p=.017). In the physiological symptoms, Soyangin frequently felt dryness in eyes, and Taeumin frequently felt uncomfortable because of the phlegm. Conclusions The theory of Sasang constitution which is a Korean traditional medicine can also be applied to the health care of Japanese, and it can contribute to the health promotion of Japanese subjects.

Purpose: We tried to evaluate the role of conventional radiotherapy alone or with neoadjuvant chemotherapy in the hypopharyngeal cancer by retrospective analysis. Materials and Methods: Between Jul.1985 and Sep.1992, 42 patients of hypopharyngeal cancer were treated by conventional radiotherapy alone or combined with neoadjuvant chemotherapy. The male to female ratio was 20:1 with a median age of 58 years, Twelve Patients were treated by conventional radiotherapy alone and 30 patients were treated by neoadjuvant chemotherapy and radiotherapy. Results: Seven Patients were Stage I,II and the patients with stage III and IV were 10 and 25, respectively at the time of presentation. The overall survival and disease-specific survival rates at 24 months were $12.9\%$ and $15.5\%,$respectively Two-year survival rates of stage I+II and III+IV patients were $50\%$ and $6.3\%,$ respectively(p(0.05). Sixteen Patients$(38\%)$ revealed CR and 26 patients$(62\%)$ revealed less than CR at the end of radiotherapy and their 2-year survival rates were $31.3\%\;and\;0\%,$ respectively(p(0.05). On univariate analysis, stage, T-stage, N-stage and treatment response were the significant prognostic factors, but only stage and treatment response were significant on multivariate analysis Conclusion : This conventional radiotherapy alone or with neoadjuvant chemotherapy does not seem to be sufficient in the treatment of most advanced hypopharyngeal cancer Therefore other treatment modalities such as hyperfractionation or concurrent chemoradiotherapy should be considered.
