The purpose of the present investigation was to compare physique, skeletal maturation and physical fitness in Korean adolescents measured between 1998 and 2007. Subjects participated in the study were a total of 473 Korean adolescents aged 12 to 13 years. In 1998, 349 adolescents were selected from a middle school, located in Sungnam city and 124 middle school students aged 12-13, located in Yongin city were participated in 2007. All measurements were conducted by one of the reseachers (Jong-Kook Song) with two different group of investigators between 1998 and 2007. Anthropometric characteristics were body mass, body height, sitting height, circumferences taken at sites of upper arm, flexed upper arm, chest, waist, hip, thigh, and calf, bone breadth taken at the sites of humerus, and femur, skinfold thicknesses taken at the sites of triceps, subscapular, suprailiac, thigh and medial calf. Skeletal maturity was assessed by TW3 (Tanner et al., 2001). Maturity scores for Radius-Ulna-Short bones (RUS) and bone age were calculated. Physical fitness parameters included flamingo balance, sit and reach, grip strength, sit-ups, standing long jump, bent arm hang, 50m shuttle run and multi-stage shuttle run. All data were analyzed by SAS Enterprise 3.0. Means and standard deviations were calculated by descriptive statistics. Independent t-test was applied to compare dependent variables between measurements. The level of significance was set at p<0.05. Results of the study showed that male adolescents aged 12-13years in 2007 had significantly higher (p<0.0001) femur diameter than adolescents in 1998. Male adolescents in 2007 had higher (p<0.05) chest, waist and calf circumferences than those of adolescents in 1998. Although no difference were found for RUS and bone age in males adolescents between 1998 and 2007 female adolescents in 2007 were significantly delayed for their skeletal maturity level compared to female adolescents in 1998. For physical fitness parameters male adolescents aged 12 years in 2007 performed better for flamingo balance (p<0.01), and 50m shuttle run (p<0.05) than those of adolescents in 1998. However, stand long jump and bent arm hang were significantly decreased in male adolescents in 2007. Female adolescents aged 12-13 years in 2007 had significantly higher flamingo balance, but female adolescents aged 12 years in 2007 performed significantly less for standing long jump (p<0.0001), bent arm hang (p<0.001) and speed (p<0.05) than those of female adolescents in 1998. In conclusions this study suggest that chest circumference for both male and female adolescents in 2007 was significantly higher than those in 1998. Skeletal maturity for female adolescents in 2007 were significantly delayed compared to female adolescents in 1998. Further study is needed to evaluate consistent various.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

영남대 생물학과에 소장되어 있는 표본과 2001년 4월~2002년 6월 사이에 채집한 표본을 대상으로 하여 한국산 야행성 맵시벌의 분류학적 연구와 출현 현황 및 숙주 관계의 분석을 실시하였다. 분류학적 연구 결과 Gauld(1970)가 영국산 야행성 맵시벌을 대상으로 한 연구에서 기록한 Mesochorinae아과, Tryphonin-ae아과, Ctenoplematinae아과, Ophioninae아과의 4아과외에 Metopinae (Metopius속)를 추가하여 한국산 야행성 맵시벌류는 총 5아과 13속을 기록하였다. 또한 한국산 야행성 맵시벌의 출현 현황을 분석한 결과 야행성으로 잘 알려진 Mesochorinae아과의 Mesochorus속, Tryphoninae아과의 Netelia속과 Ophioninae아과가 전체 야행성 맵시벌 증 95%를 차지하였다. 속별 출현현황을 살펴보면 Netelia속이 393개체가 출현하여 가장 많은 수를 나타내었으며 Ophi-on속, Mesochorus속, Enicopilus속도 전체 출현 분류군 중 높은 비중을 차지하였다. 월별 현황을 살펴보면 전반적으로 4월에서 11월 사이에 걸쳐 나타나는데, Op-hioninae아과는 5월과 7월에, Tryphoninae아과는 6월에 집중적인 출현 빈도를 보였다. 숙주의 분류군에 따른 야행성 맵시벌의 기생 양상을 살펴보면 대부분이 나비목을 대상 숙주로 하고 있으며 Mesochorinae아과와 Ctenopelmatinae아과는 벌목에도 많은 종이 기생하는 것으로 나타났다. 특히 Mesochorinae아과의 Cidaphus속은 위생 해충으로 분류되는 기생파리과(Tachinidae)에도 기생하는 것으로 나타나 위생 해충을 구제할 수 있는 천적 분류군으로 연구될 수 있는 가능성을 보였다. 숙주의 식성에 따라 살펴보면 부식성의 먹이를 섭식하는 부식성(saprophagus) 숙주, 곤충의 유충을 섭식하는 식충성(entomophagus)인 숙주가 소수 출현하였고 기생생활(parasite)을 하는 숙주도 다수 출현하였으나 대부분의 야행성 맵시벌의 기생 대상 숙주는 주로 식물을 해하는 식식성 곤충(phytophagus)으로 나타났다. Nocturnal Ichneumonidae, which was called yellow-brown ichneumonoid, included several subfamilies adapted for nocturnal activity. Taxonomic study of nocturnal ichneumonoid has been investigated by Gauld(1975) but examination of Korean nocturnal ichneumonoid has not been provided until now. This present study: the taxonomic revision, Appearance state and Host-parasite relation analysis of nocturnal ichneumonoid, were examined using Korean peninsula specimens. As the result. approximately 13 genera referable to 5 subfamilies appeared regularly in light trap. Genus MetopiudSubfamily Illetopinae) were newly recorded in nocturnal ichneumonoid. Tryphoninae and Ophioninae, which were dominant in appearance taxa! occupied 96% of total numbers of individuals, and majority of them were taken from May to November. Nocturnal ichneumonoid are parasitoids of part of immature holometabolous insects(Coleoptera, Diptera, Hymenoptera, Lepidoptera). Lepidoptera is the most common hosts of nocturnal group except Mesochorinae and Ctenopelmatine. In large number of Mesochorinae are koinobiont hyperparasitoids of ectoparasitic or endoparasitic BraconiddHymenoptera), and, less frequently, of Tachinidae(Diptera1. Also, Ctenopelmatinae are koinobiont endoparasitoids of Symphyta and, rarely, Lepidoptera. Majority of nocturnal ichneumonoid hosts are phytophagous, feeding plant taxa, and many host of Mesochorinae taxa are parastoids, and a few host are saprophagus or entomophagus.

18세기 말 병산서원의 강학 활동과 그 의의

박종배(Park, Jong-Bae) 대동한문학회 2021 大東漢文學 Vol.67 No.-

이 논문에서는 먼저 17~18세기 병산서원의 교육 상황을 살펴본 다음, 18세기 말 병산서원에서 이루어진 ‘通讀’과 ‘居齋’, ‘考講’ 등의 강학 활동의 배경 및 성격에 대해 알아보았다. 그리고 강학 활동 이후의 병산서원에 생겨난 변화들을 살펴보면서 18세기 말의 강학 활동이 병산서원의 역사에서 갖는 의의에 대해 논의하였다. 논문에서 살펴본 바에 따르면, 병산서원의 강학 활동은 18세기 서원 강학 운동을 배경으로 이루어진 것으로, 강학의 유형이나 방식 면에서 전혀 새로울 게 없는 성격의 것이었다. 안동이나 인근 영남 지역 서원들의 상황에 비추어 보아도 시기상 늦게 이루어진 편에 속한다. 하지만 그것이 이후 병산서원의 역사에 미친 영향은 결코 작지 않았다. 1781년 류종춘이 원장을 맡으면서 시작된 일련의 강학 활동은 병산서원이 침체를 벗어나 중흥의 길에 들어서는 결정적 계기가 되었다고 할 수 있다. In the late 18th century, three types of educational activities were held at Byeongsan Confucian Academy: “Tongdok[whole reading seminar],” “Geojae[boarding study],” and “Gogang[examination].” In this paper, I first examined the educational situation of Byeongsan Confucian Academy in the 17th and 18th centuries, and then examined the types, backgrounds, and characteristics of the educational activities conducted at Byeongsan Confucian Academy in the late 18th century. In addition, I discussed the significance of educational activities in the history of Byeongsan Confucian Academy, looking at the changes that occurred in Byeongsan Confucian Academy after these educational activities. According to the paper, Byeongsan Confucian Academy s educational activities were based on the 18th century Seowon[Confucian Academy] Educational Movement, and there was nothing new in terms of the type or method of teaching. Considering the situation of the Confucian academies in Andong and nearby Yeongnam area, it is considered to be late in the period. However, their impact on the history of Byeongsan Confucian Academy was never small. A series of educational activities, which began in 1781 when Ryu Jong-chun was the director, served as a decisive opportunity for Byeongsan Confucian Academy to escape the recession and enter the path of restoration.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

OSAS(obstructive sleep apnea syndrome) is becoming more and more of importance nowadays. Therefore the study concerning OSAS is very important. Most of the studies which have been reported were comparison of upper airway size and change of skeletal class Ⅰ group and skeletal class Ⅲ group respectively. But, most of the showing OSAS have pharyngeal narrowing combined with more or less distinct maxillary and mandibular deficiency. Therefore the aim of this study is to see posterior airway space and hyoid bone position in patients affected by class Ⅱ malocclusion and treated with orthognathic surgery. we measured the lines between selected upper air way landmarks on lateral cephalometric x-ray films of skeletal class Ⅱ 30 persons who had not been operated yet, were within 2 weeks after operation, were 6 months after operation. And we compared them respectively and analyzed them with pairing t-test, pearson correlation coefficient and multiple regression analysis. The results were as follows. First of all, skeletal class Ⅱ group was increased in all the level of PAS, especially PAS(MK) and PAS related to hyoid bone(H-phW, H-PhW(Me-H)) was significantly decreased within 6 months after operation but that was larger than preoperation. And then the PAS was increased after mandibular advancement surgery. While there was no significant correlation between PAS and surgical methods, there was statistical significance between PAS and a number of surgical movement. At last, the hyoid bone was advanced within 2 weeks after operation but relapsed within the follow up period. In the end of the study, it was turned out that PAS was always wider without distinction of the region after the operation and that there was significant correlation between the moving volume of hard tissues and the changing quantity of PAS( ; how much PAS was changed according to the moving degree of hard tissues). After this, to be based on the study, I consider that OSAS demands further study and that it is necessary to do more practical applications to the patients.
