This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

사설시조 변모양상 연구 : 형식과 표현의 변화를 중심으로

신윤경 이화어문학회 2005 이화어문논집 Vol.23 No.-

This thesis examines the formats, and expressional conditions of the Saseol-Sijo(辭說時調) that had transformed according to the times. The openness and dynamics in form and expression, which are typical of the Saseol-Sijo, were the fundamental cause for changes. The openness of form facilitates the lengthening, motivation, and correlation with the other genres, and various expressions were used so that they could incur the emphasis of meaning and language-play. The changes in the Saseol-Sijo jibe not only with such external causes as the dynamic changes of society and the differentiation of music from 17th century to 19th century, but also with the internal characteristics of the Saseol-Sijo, i.e., openness and dynamics of form and expression. The wariness, not to take with either restoration or renovation at a turning point, led to the changes in the Saseol-Sijo, the fact of which, in turn, motivated this Sijo to keep itself in existence. Through the discussion above, the study of this thesis aims to classify the aspects of the Saseol-Sijo into expression, and form, and to uncover the triggering force for those changes and examine the implications of the changes that the Saseol-Sijo had undergone. Considering that the changes in the classical poetry, which ensued from primitive ballads, resulted from a novelty-pursuing atmosphere where the preceding period was stigmatized as outdated custom or aesthetics, and a new enjoying class, the changes in the Saseol-Sijo in accordance with the times can be looked upon as a miniature of the changes that occurred in the classical poetry through history. In this vein, the aspects of the changes in the Saseol-Sijo are meaningful in that a single genre survived by going through varied shapes and contents within itself, in order to meet the demands of the times.

신윤경,김영재,김정욱,장기택,이상훈,한세현,김종철 大韓小兒齒科學會 2007 大韓小兒齒科學會誌 Vol.34 No.4

Anatomic abnormalities of teeth development include the presence of a single maxillary central incisor at midline instead of two central incisors. The incidence of cases with a single maxillary central incisor is approximately 1 in every 50,000 live births. single median maxillary central incisor(SMMCI) may be a integral manifestation of anyone of a number of syndromes. It has been reported an association with several midline disorders which have varied in severity. A SMMCI has also been reported as an isolated finding. But in some cases, it has been considered as an incomplete expression of autosomal dominant holoprosencephaly. So any patient who appears for treatment with a SMMCI should be referred for a detailed medical examination to exclude other associated systemic abnormalities and for mutation analysis to facilitate correct diagnosis and the provision of appropriate genetic counseling. Early orthodontic treatment is needed to minimalize emotional trauma of child. This case report was about three patients with a SMMCI as isolated finding. The purpose of these case reports was to present cases of single maxillary central incisor not associated with other disorders. Single Median Maxillary Central Incisor(SMMCI)는 상악 중절치 형성부전으로 하나의 상악 중절치가 정중앙에 위치하는 치아 발달의 해부학적 이상을 의미한다. 50,000명 중에 1명 꼴로 발생할 정도로 아주 드물며 각종 증후군 및 정중선 이형성을 보이는 발달장애와 연관되어 나타나는 것으로 보고되고 있다. SMMCI는 다른 이상과 연계되지 않고 독립적으로 나타날 수도 있으나 상염색체 우성유전인 전전뇌증(holoprosencephaly)의 경미한 발현일 가능성이 있으므로 유전자 상담이 필요하다. 또 특징적인 안모 및 구강 상태를 보이므로 환아의 바람직한 신체적,정서적 발달을 위해 조기에 교정적 접근이 필요하다. 본 증례는 다른 이상 소견을 보이지 않는 세 명의 SMMCI 환아의 증례를 보고하는 바 이다.

The purpose of this study in order to present a study direction on the bathroom which is growing in the importance of life viewpoint, surveyed the changes according to the study method (survey method, survey objects, the number of objects) and the study skill by the year and the study area - first centering on the theses related to academic theses and dissertations publicized until now - and tried to present a systematic study direction on the bathroom, which would be required in future through categorization. The methods of the study was to collect data related to the journals and theses study and to analyze 115 papers. The data were processed by SPSS PC+ windows version 15.0 program and were analyzed using the frequencies analysis, crosstabulation analysis, and Cluster Analysis are implemented. The results are as follows. It needs repeated research of lifestyle through a changed bathing way by a change of time. And through this research it needs to investigate the actual conditions of present bathrooms. It was thought that the various study methods, including an emotional study method using image or color as well as sentence through the web surfing using the internet in addition to using the existing methods, are needed. The survey method is important in the number of the survey objects as the quantitative study, but it was also thought that the qualitative study, including field observation, focus group interview and interview in depth, has to go abreast appropriately in order to variously accept the opinions of residents. In addition to the development of new study area, a reanalysis plan through the extraction • synthesis of data studied so far has to be conducted because the basic direction was presented. The study on psychology and behavior of children and students, which have not been treated in the survey objects, in addition to adults, housewives, the aged, and the disabled, has to be conducted together. The study on the regulations related to heating and soundproofing, in addition to water supply • draining facilities, ventilation and construction, has to be gone abreast. We sincerely hope that this study is anticipated to be used for the material to present a study direction in order to arrange more systematically the bathroom study.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

신호준,지영진,조명수,김형일,박연희,임경일 아주대학교 의과학연구소 1998 아주의학 Vol.3 No.2

Acanthamoeba spp. spread in soil, ponds, air and swimming pool, cause a granulomatous amoebic meningitis and amoebic keratitis in human and experimental animals. Their classification had depended upon morphological characteristics and physiological conditions such as thermophilic status and generation times. However, because amoeba species showed the morphological and physiological diversity in isolates, many attempts have been made on identification of Acanthamoeba spp. Restriction fragments length polymorphism (RFLP) analysis of IBS-small subunit ribosomal RNA (srRNA) was an useful tool for classification among morphologically and genetically closely-related species. In this study, 18S-srDNAs of amoebae were amplified by PCR with primer encoding 18S-srRNA gene and digested with restriction endonudeases, and RFLP analysis was applied on classification of Acanthamoeba Korean isolates (YM-4, YM-5 and YM-7), comparing with reference amoebae, A. culbertsoni, A. polyphaga and A. royreba. Trophozoites of six Acanthamoeba spp. had typical acanthopoda, but did not show any morphological differences. Cyst of Acanthamoeba sp. YM-7 was similar to that of A. polyphaga which was designated as group Ⅱ Acanthamoeba. Morphologically other amoebae belonged to group Ⅲ Acanthamoeba. Digestion of 18S-srDNA with six enzymes, Dde Ⅰ, Hae Ⅲ, Hind Ⅲ, EcoR Ⅰ, Rsa Ⅰ and Sph Ⅰ, resulted in various DNA fragments. Using the method of Nei and U (1979) for RFLP analysis, genetic divergence was not observed between A culbertsoni and Acanthamoeba sp. YM-4. Between A. culbertsoni and Acanthamoeba sp. YM-5, genetic distance was 0.070, 0.364 between Acanthamoeba sp. YM-4 and A. polyphaga, and 0.277 between Acanthamoeba sp. YM-7 and A. polyphaga. In comparison with A. culbertsoni and A. polyphaga, Acanthamoeba sp. YM-7 showed genetic distance of 0.330 and 0.154, respectively. Thus, Acanthamoeba sp. YM-7 is a similar species to A. polyphaga. Acanthamoeba sp. YM-5 is a different species from A. polyphaga, but closely-related to A. culbertsoni. Acanthamoeba sp. YM-4 can be classified as a subspecies or a strain of A. culbertsoni.

신영재,성경윤 安東大學校 工業技術硏究所 2000 공업기술연구논문집 Vol.7 No.1

본 논문은 일단은 고정되고 타단은 첨단 질량을 가지며, 이질 재료에 부분적으로 묻혀 있는 선형 원뿔대를 베르누이-오일러 빔으로 모델링하여 선형 원뿔대의 지배방정식을 유도하여 주파수 방정식 및 해를 구하였으며, 선형 원뿔대의 제반 무차원 변수에 대한 수치해석을 통하여 원뿔대의 진동특성 등을 분석, 고찰하였다. A linearly tapered column immersed partially in other material is considered and is modelled as a linearly tapered Bernoulli-Euler beam fixed at the bottom with a concentrated mass at the top. Its governing equations is derived and its free vibration analysis is performed for various boundary conditions. And the rotatory inertia of the eccentric lumped tip mass is considered. The problem of determining the natural frequencies leads to a eighth order determinant. The solutions of the frequency equations are obtained numerically. The non-dimensional frequency parameters are given in tabular form and the influence of non-dimensional parameters on natural frequency is discussed for various conditions.

K이 흡착된 Si(111)7×7표면에 대한 RHEED 연구

박종윤,이순보,이경원,안기석,신익조,강건아 성균관대학교 1990 論文集 Vol.41 No.2

상온 및 200℃∼600℃의 Si(111) 7×7 표면에 칼륨(K)을 증착하였을 때의 표면격자구조 변화를 RHEED로 관측하였다. K 증착시 Si(111)7×7 기판의 온도가 상온인 경우, 어느 일정한 증착시간(포화덮임률에 도달했다고 추정되는 증착시간)이 지난 후에는 원래의 깨끗한 Si(111)7×7 패턴과 유사한 Si(111) 7×7-K 패턴이 관측되었고, 증착시간을 증가시켜도 RHEED 패턴은 변화하지 않았다. 이것을 annealing하면 350℃까지는 RHEED 패턴에 변화가 없다가 그 이상의 온도가 되면 서서히 원래의 7×7 패턴으로 되돌아가기 시작한다. Si(111) 7×7기판의 온도를 200℃∼600℃로 유지하면서 K을 일정시간(450℃에서 3×1이 형성되는 증착시간)이상 증착시킨 경우에 250℃까지는 상온의 경우와 비슷한 형태의 변형된 7×7 패턴이 관측되고, 300℃∼550℃일때는 3×1, 550℃ 이상에서는 1×1 구조가 관측되었다. 이때 300℃∼550℃에서 형성된 Si(111) 3×1-K 구조는 450℃에서 1분 정도 annealing 하면 항상 Si(111) 1×1-K 구조로 상전이가 일어남을 관측하였다. Potassium adsorbed surface structures of Si(111) 7×7 surface at room and high temperatures(200℃∼600℃) were investigated by RHEED. Potassium adsorption on the Si(111) 7×7 surface to saturated coverage at room temperature changed the RHEED pattern of Si(111) 7×7 to Si(111) 7×7-K. Subsequent heating of the Si(111) 7×7-K surface above 350℃ results in a Si(111) 7×7 with desorbing K. The RHEED pattern of the K-adsorbed on the Si(111) 7×7 surface up to the adsorption temperature of 250℃ was the modified 7×7 pattern, quite similar to that of the Si(111) 7×7-K, observed at room temperature. The 3×1 structure was observed in the temperature of adsorption between 300℃ and 550℃. Regardless of the adsorption temperature, a phase transition always took place from the Si(111) 3×1-K structure to Si(111) 1×1-K after annealing at 450℃ over 1 minute.

The octadodecanoxy derivative of the phthalocyanine which has such long hydrocarbon chains around the skeleton of the phthalocyanine was synthesized. First of all, ortho-catechol was treated with 2 moles of 1-bromododecane to yield ortho-didodecanoxybenzene(I). Second, bromination of I resulted in dibromo-didodecanoxy benzene(II) where the para positions to the dodecanoxy groups were brominated. Finally, reaction of II with an excess of CuCN under an N₂atmosphere gave the intermediate dicyano-didodecanoxy-benzene(III), in situ, and futher heating in dry DMF with more CuCN gave the final product, octadodecanoxy derivative of the phthalocyanine. The synthetic method developed herein provides a general way to synthesize the variety of the phthalocyanines which displays many different substituents such as long hydrocarbons around its skeleton and contains a various metal inside of the phthalocyanine.
