H-S Lee, Y-S Lee, J-C Byun. The effects of EMG activity and blood fatigue makers on balance taping treatment by exercise type. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 271-284, 2004. The purpose of this study was to analyse the EMG activity of selected muscles with balance taping treatment and blood fatigue makers which accumulated during exercise of progressive maximal intensity. Ten male college students who did not experience any cardiovascular and musculo-skeletal disease were participated in this study. Balance taping were applied to rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinous, semimembranous, and around knee joint. Isokinetic knee joint flexion/extension force, EMG activity, lactate and ammonia as blood fatigue makers during progressive maximal intensity exercise were measured for with/without applying balance taping. The results indicated that although flexion force of total work at 60˚/sec with taping was increased applied taping did not affect to the aerobic exercise ability parameters. Lactate level as blood fatigue makers during progressive maximal intensity exercise after taping was decreased but the ammonia level did not change with same treatment. In isokinetic knee joint test at the angular velocity of 60˚/sec, 180˚/sec, and 240˚//sec the taping treatment did not affect to any selected muscle EMG activities except maximal EMG of vastus lateralis at 240˚/sec.

연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

새만금 간척지 첨단온실 에너지 설계를 위한 풍환경 및 온실 피복재의 영향 분석

서효재(Hyo-Jae Seo),서일환(Il-Hwan Seo),노득하(Deuk-ha Noh),이학성(Haksung Lee) (사)한국생물환경조절학회 2023 생물환경조절학회지 Vol.32 No.1

본 연구에서는 새만금과 같은 간척지를 활용하여 대규모 첨단온실단지를 조성하는 경우 간척지의 환경적 특수성 중 높은 풍속에 따른 유리 단열재의 에너지 효율을 평가하였다. 현장에서 주로 사용되는 온실 단열재 중 4가지에 대한 평가 결과, 최대 37.4%의 에너지 차이를 보여, 온실 피복재의 선정이 중요함을 제시하였다. 이를 바탕으로 일반적인 내륙에서의 온실을 설계하는 것과 달리, 간척지에서는 내재해성 온실규격을 따라 시설을 설계하여야 하며, 에너지 소비량은 높아진 풍속과 재질을 고려하여 산정되어야 한다. 본 연구의 결과는 에너지 효율성을 온실 피복재의 종류와 풍속에 따라서 제시하고 있으며, 이는 대규모 첨단온실 조성 시 에너지 소비량을 예측하고, 이를 바탕으로 신재생에너지원을 포함하는 에너지 설계에 활용될 수 있다. The external weather conditions including temperature and wind speed in the Saemangeum reclaimed land is different from that of the inland, affecting the internal environment of the greenhouse. Therefore, it is important to select an appropriate covering material considering the insulation effect according to the type and characteristics of the covering material considering the weather condition in the Saemangeum reclaimed land. A hexahedral insulation chamber was designed to evaluate the insulation efficiency of each glass-clad material in the outside weather condition in reclaimed land. In order to evaluate the insulation effect of each covering material, a radiator was installed and real-time power consumption was monitored. 16-mm PC (polycarbonate), 16-mm PMMA (polymethyl methacrylate), 4-mm greenhouse glass, and 16-mm double-layered glass were used as the covering materials of the chamber. In order to understand the effect of the external wind directions, the windward and downwind insulation properties were evaluated. As a result of comparing the thermal insulation effect of each greenhouse cover material to single-layer glass, the thermal insulation effect of double-layer glass was 16.9% higher, while PMMA and PC were 62.5% and 131.2% higher respectively. On average the wind speed on the windward side was 53.1% higher than that on the lee-wind side, and the temperature difference between the inside and outside of the chamber at the wind ward side was found to be 52.0% larger than that on the lee ward side. During the experiment period, the overall heating operation time for PC was 39.2% lower compared to other insulation materials. Showing highest energy efficiency, and compared to PC, single-layer glass power consumption was 37.4% higher.

To identify aberrantly hypermethylated DNA in lung cancer cells we established a genome-wide analysis for hypermethylation sites, namely Methyl DNA Isolation and Amplification (MeDIA) coupled-CpG microarray analysis. In the comprehensive methyaltion profiling analysis between human lung cancer, A549 cells and normal NHBE cells, we observed that several clusters of genes show a significant level of aberrancy in CpG island methylation pattern in cancer cells compared to normal cells. We further identified PCDHGA12 gene as a new marker of non-invasive diagnostics for lung cancer based on followings. 1) Transcription of PCDHGA12 gene is reactivated after treatment of A549 cells with demethylating agent. 2) Bisulfide clonal-sequencing reveals that CpG island of PCDHGA12 shows a distinctive differential methylation between two cell lines. 3) Pyrosequencing-based quantitative methylation assay for such region in tumor and non-tumorous tissues from lung cancer patients shows aberrant hypermethylation in 37 (92%) of the 40 tumor tissues. In clinical validation by pyrosequencingin induced-sputum of lung cancer patients (n=87) and healthy controls (n=51), we observed aberrant hypermethylation incident at significantly elevated level in samples derived from lung cancer patients. According to the optimal threshold calculated by ROC curve analysis, sensitivity and specificity of PCDHGA12 was 86.2% and 82.4%, respectively. PCDHGA12 methylation status could be a potential methylation biomarker alone or combined with others for the screen and the detection of relapse of lung cancer.

이효설,최형준,최병재,손홍규,이제호 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.4

치은섬유종증(Gingival fibromaotsis)은 치은조직의 섬유성 증식을 나타내는 드문 구강질환이다. 원인은 명확히 규명되지 않았으나 상염색체 우성 또는 열성의 유전성이거나 특발성일수 있다. 주로 영구치 맹출 시기에 나타나기 시작하나, 드물게 유치열기나 출생시부터 이환되는 경우도 있다. 치은은 서서히 증식하여 치아의 해부학적 치관부위를 덮거나 구개 변이를 일으켜 혀 운동장애를 야기하거나 입술 폐쇄를 방해하기도 한다. 이 증례의 환아는 14개월 된 여아로 출생 시부터 계속딘 치은증식을 주소로 내원하였다. 특별한 가족력이나 의학적 병력은 없었고, 임상 유전검사 결과 알려진 어떤 증후군으로 진단되지 않았으나, 신체발달이 지연되어 있었다. 펀치 생검을 하였으며, 조직검사명은 치은섬유유종증이었다. 가족력이 없어 특발성 치은섬유종증으로 진단하였다. 환아의 연령 및 전신 상태를 고려해 치은 절제술 등의 외과적 치료는 연기하기로 하였다. Gingival fibromatosis is a rare condition characterized by varying degrees of gingival hyperplasia. Gingival fibromatosis usually occurs as an isolated disorder or can be associated with a variety of other syndromes. It usually appears at the time of eruption of permanent dentition but, can develop at the time of eruption of the primary dentition and rarely at birth. It may deform palatal contour and subsequently restrict the tongue movement, resulting in interference during speech and mastication. In addition, it incapacitates maintenance of normal lip closure. A 14-month-old girl visited the department of pediatric dentistry, Yonsei University Dental Hospital, for the congenital gingival overgrowth. There was no one in the family, who showed similar pattern of gingival growth. The intraoral clinical examination revealed generalized severe enlargement throughout the maxillary and the mandibular arches. Enlarged gingival tissue was pink and had firm consistency. She was referred for chromosomal analysis, which confirmed absence of any known syndrome. Under local anesthesia, "Punch-biopsy" was performed on the labial area, and the specimen was histologically diagnosed as gingival fibromatosis. For she did not have any medical problem nor familiar history, she was diagnosed as having idiopathic gingival fibromatosis. Regarding her age and behavior, close follow-up was decided.

이건동,이재현,박효덕,이덕동,최흥문 경북대학교 센서기술연구소 1991 센서技術學術大會論文集 Vol.2 No.1

SnO_(2) doped with TiO_(2) and other activating agents, is used as a raw material to prepare humidity sensors. SnO_(2) is an n-type semiconductor whose resistance is described as a function of relative humidity. SnO_(2)/TiO_(2) thick film humidity sensors have been fabricated by using typical silk screen printing techniques. The humidity sensitivity of SnO_(2)/TiO_(2) thick film has been investigated. And the sensing characteristics of the fabricated SnO_(2)/TiO_(2) sensors such as resistance change and response time, has been investigated from R.H.20 % to 90 %. Experimental results show that the impedance-humidity characteristics of the humidity sensors depend on the microstructure of surface roughness and pore size distribution.

이현개,호종수,이승재,박효일 인제대학교 1982 仁濟醫學 Vol.3 No.4

자발성 뇌간 혈종은 흔하지 않으며 특히 중뇌에 생긴 자발성 혈종은 대단히 드물다. 뇌간에 생긴 혈종은 생긴 장소와 크기에 따라서 다양한 신경학적 증상과 vital sign의 변화를 보인다. ocular sign 및 vital sign의 변화와 의식상태 등에 의해서 뇌간 혈종의 위치를 식별할 수도 있다. 뇌간 혈종이 있는 환자를 치료하는 중에 환자의 의식상태는 혈압과 밀접한 관계를 보이며 수축기 혈압이 140mmHg이거나 이보다 약간 높은 상태에서 비교적 안정될 때는 환자의 의식이 호전되었고 강하시에는 의식의 악화를 보였으며 또한 혈압에 따라 이외의 신경학적 증상의 변화를 보였다. 본 교실에서는 Brain CT에 의해서 자발성 뇌간 혈종 5예, 즉 중뇌 혈종 1예, 뇌교 혈종 2예 및 뇌교-중뇌 혈종 2예를 경험하였다. Spontaneous brain stem hematoma is not common, especially spontaneous midbrain hematoma is extremely rare. Brain stem hematoma leads to variable neurological deficits and wide variations of vital signs correspending to its location and volume. It is possible to localize the hematoma in the brain stem by means of changes of ocular signs and vital signs, and the level of consciousness. During treatment of the patients with brain stem hematomas we found that the level of patient's consciousness was closely related to the level of blood pressure. At or slightly above 140mmHg of systolic pressure the patient's consciousness was markedly improved, but the decreased systolic pressure caused its deterioration. Also according to level of blood pressure other neurological findings were slightly variable. We hove experienced five cases of spontaneous brain stem hematoma which were diagnosed with brain CT. They were a case of midbrain hematoma, two cases of pontine hematoma and two cases of pontomesencephalic hematoma.

한국 화교 및 화교 이동에 관한 연구

The population of Korean Chinese in 1979 was 30,117, among which 94% were from the Shantung peninsula. Compared to the Southeast Asian Chinese, the society of Korean Chinese are a homogeneous ethnic group which uses the same language, came from the same area, and follows the ideology of anti-communism as directed by the Taiwan government. 78% of Korean Chinese are engaged in restaurant businesses, and the others are engaged in general merchandise retailing, Chinese herbal medicine, Chinese herb shops, tearooms, public bath businesses, and tailor shops. In general, job and business opportunities open to Chinese are very limited in Korea. The major organization of Chinese society is " the Chinese Central Association" to which fifth-one local associations belong. Chinese associations play a middleman role between Chinese people and the Chinese embassy in Seoul by reporting people's opinions to the embassy and sending messages from the embassy to the people. Other voluntary organizations are restaurant business associations, local and surname associations, religious and educational associations, and so on which add up to twenty. Most of the voluntary organizations are usually linked to one another through interlocking relations. Thus, leaders in a Chinese community play multiple roles in different associations. Most Chinese children attend Chinese schools which consist of one year of kindergarten, six tears of primary school, and six years of high school. As of 1980, there are nationwide one kindergartens, thirty-nine primary schools, and five high schools. The years of 1882 saw the beginning of Chinese immigration to Korea which was the result of a treaty on trade between Korea and China. Although there were only 209 Chinese in 1883, The Chinese population in Korea reached the level of 82,600 people in 1942. After 1945, however, the division of the country forced two-thirds of the Chinese to live in the northern part of the peninsula. The drop of Chinese immigration after the communalization of mainland China in 1949 also contributed to the decrease of the Chinese population in South Korea along with the government's ban on any immigration into the country. Since then the Chinese population increased only by natural growth, and it reached 32,980 in 1972. In the 1970's, the Chinese population slowly decreased to reach the level of only 29,600 in 1980. The decrease of the Chinese population in the 1970's has been the result of migration of Chinese people to foreign lands. In order to find the trend of their actual mobility, the statistics of Chinese entry-exit have been reviewed. In 1967 the number of entries was 2,600 and the number of was 2,800. Since 1970 it shows a sharp increase and, in 1977, the number of Chinese entering the country was 18,300 and the number leaving the country was 20,00. In other words, the Korean Chinese changed their way of life by traveling back and forth frequently, and some of them even live in Taiwan, visiting Korea once a year only to renew residenceship. These people can be categorized as 'mobile population'. The number of reentry for residence in 1979 was 6,638 which is 22% if the Korean Chinese. If we assume that the average Chinese goes overseas and comes back twice a year, it can be estimated that 11% of Koran Chinese belong to the category of 'mobile population'. In addition, the number of visas issued by the Chinese consulate in Seoul, the number of entries and exits of overseas Chinese to Taiwan, and the number of graduates from Taiwan colleges and junior colleges were also analyzed to prove the high mobility of Korean Chinese in the 1970's. Most of the Korean Chinese who moved out of Korean go to Taiwan and to the United States of America. In this paper, only migration to Taiwan has been analyzed. Interviews were conducted during the period of January and February of 1980 with fifty one Koran Chinese who reside in Taiwan. Life in Taiwan for these emigrants was proven not to be that of a comfortable and leisurely nature. Instead, Korean Chinese have found themselves in a category of a 'minority in their fatherland, i.e. the Korean Chinese formed their own small society by getting together by themselves, having certain common stores they shop, and having little chance to make new Taiwanese friends. The reasons are that either they are too busy keeping stores or small restaurants, or they spend most of their time seeing each other. Moreover, those who do not have any jobs usually engage in a kind of 'shuttle trade', which is conducted by traveling between Korea and Taiwan. Traveling between the two countries, Chinese carry items like herbal drugs, jewels made of ivory, coral, and jade, tapestries, toys and so on from Taiwan to Korea, and blankets, bed spreads, clothes, dresses, ginseng products, and others from Korea to Taiwan. This shuttle trade has become possible by the well systematized process including institutions like drug stores, jewelry stores, and gift shops in Taiwan, and many middleman who purchase the carried items. The store managers in Taiwan take all the carried items from Korea, as well as supplying items to be carried to Korea. Most Chinese migrate to Taiwan as individuals rather than as a whole family. Many Chinese families in Korea end up having their members spread out in different countries, becoming a 'multinational family'. Among the fifty one cases studied, thirty (58%) went to Taiwan for study. Among thirty cases, only seven were attending colleges at the time of study, the rest having been settled in Taiwan after gradation or dropping out of school. The tread is likely to continue that Korean Chinese students entering Taiwan colleges will end up setting in Taiwan more or less permanently. Chinese students in Korea are encouraged by teachers and parents to apply to colleges in Taiwan rather than applying to Korean colleges. One of the major reasons is the way they were educated in primary textbooks under a Chinese curriculum, and are taught by Taiwan colleges educated teachers. The Korean governments liberal educational police for foreigners helped to create the above situation. Therefore Chinese students are well exposed to Chinese culture and society before they go to Taiwan. The strong ethnic identity achieved by pure Chinese education surely induced many Chinese students to apply to Taiwan colleges and to settle in Taiwan. Moreover, other policies of the Korean government in the areas such as naturalization and financial aid, are very restrictive toward Chinese. Curiously enough, a seemingly contradictory policy of permissive education and restrictive naturalization and commerce has maintained a strong ethnic among Chinese people. As a result Chinese began to search for an alternative to give their ethnic identity not a weakness but a pride. Since being a Chinese is a weakness in Korea, Chinese people moved out, leaving their Korean hometowns. Korean Chinese society has a basic group identity as H. Isaacs remarked in "Basic Group Identity: The Idols of the Tribe" ( in Ethnicity : Theory and Experience, edited with an introduction by N, Glazer and Daniel P, Moynihan, 1975). "The Chinese group in Korea is not used as a political or economic unit un order to get ethnic interest as Glazer, Mpynihan and Patterson indicated in the same book. Rather Chinese identity became an ideology in that society. As Aronson insisted, Chinese identity in Korea operates as a leading ideology among Chinese people in Korea. Being one of the first exploratory researches on Korean Chinese, this study has taken a general approach. Future research should deal with more specific subjects such as interethnic relationships between Koreans and Chinese, intermarriages between them, assimilation patterns, the different value systems between the first, second, and third generation Chinese and other anthropological issues. And since many Chinese moved to the United States, a follow-up study of Korean Chinese in the U.S. will be an interesting cross-cultural study.

This paper proposed an extracting algorithm of human facial components for the recognition of facial expressions. First face image is acquired using the Haar-like feature mask from an input image. The face image is divided into two images. One is the upper image including eye and eyebrow. The other is the lower image including mouth and jaw. The extraction of facial components, such as eye and mouth, begins getting eye image and mouth image. Then eigenfaces are produced by the PCA training process with learning images. An eigeneye and an eigenmouth are produced from eigenfaces. Result eye image is obtained by template matching the upper image with the eigeneye, and the mouth image is obtained by template matching the lower image with the eigenmouth. The simulation results show that the proposed method has superior extraction ratio than previous method.
