Background: Various types of miniplates have been developed and used for the reduction of facial bone fractures. We introduced Yang's Keyhole (YK) plate, and reported on its short-term stability. The purpose of this study was to evaluate the long-term stability of the YK plate, as a follow-up study, by examining the patients who had used the YK plate among the patients with the reduction of mandible fractures and who visited for plate removal. Methods: We reviewed the medical records of 16 patients who underwent mandibular fracture fixation using a YK plate (group I) and 17 patients who underwent mandibular fracture fixation using a conventional plate (group II). Assessment was then made on malunion, occlusal stability, discomfort during the application, and clinical symptoms. Results: From January 2015 to December 2017, a total of 36 patients underwent mandibular fracture surgery using a YK plate. A total of 16 patients received plate removal. Among them, 15 were male and 1 female. The average age was 26 years. The applied surgical sites were the 12 on mandibular angle, 4 on mandibular symphysis, and 2 on subcondyle. The application period of YK plate was an average of 335 days. During the same period, 45 people underwent surgery on the conventional plate. A total of 17 patients received plate removal. Among them, 15 were male and 2 females. The average age was 36 years. The applied surgical sites were the 8 on mandibular angle, 4 on mandibular symphysis, and 2 on subcondyle. The application period of the conventional plate was an average of 349 days. No malocclusion occurred at the time of removal, and occlusion was stable. No patient complained of joint disease or discomfort. Conclusion: The YK plate system, in which the screw was first inserted and the plate was applied, for clinical convenience did not cause any particular problem and no significant difference from the conventional plate.

Differences in dietary intake of Korean Americans (KA) by the length of residence in the U.S. were studied in relation to health and disease patterns in Michigan. Of 1860 questionnaires mailed, 637 (34.3%) responded with demographics, anthropometrics, self-reported disease patterns, lifestyle, and dietary patterns (93-item FFQ developed for KA). Complete responses were available for 498 people (263 men, 253 women, aged 30-87 yr), who were then divided into three groups based on the number of years lived in the U.S.: 15y, 16-25y, 26y. Age-adjusted weight, height, BMI, and waist to hip ratio were within the normal ranges and did not differ among the three groups. Chronic diseases frequently reported in men and women (age-adjusted) included hypertension (14.4%, 14.1%), digestive diseases (5.4%, 8.5%), diabetes (3.6%, 4.9%), and arthritis (3.3%, 12.5%), respectively. The length of residence in the U.S. was inversely associated with the age-adjusted prevalence of digestive diseases (12.4%, 6.5%, 0.4% in men, 13.0%, 11.7%, 0% in women). The length of residence was positively associated with health consciousness, receiving regular health care, taking supplements regularly, and exercising, while inversely related to smoking. The majority favored American foods for breakfast and Korean foods for dinner. Foods frequently consumed included cooked rice (w/other grains), kimchi, coffee (w/cream and sugar), bread (white and dark), citrus juice, milk (low fat and skim), lettuce and cucumber, apple, seaweed, and soda. Intake frequency of the Korean starch food group was inversely associated with the length of residence for both men and women (p<0.001), but not with the American starch food group. Fat intake did not differ by the length of residence in the U.S. The dietary changes were associated with the length of residence and chronic disease patterns for the first generation of KA, which should be further examined 'for the subsequent generation of KA.

The purpose of this study was to provide a fundamental information for plan for positive and active participation or execution of exercise in Female elderly. Questionaire about the Leisure activities, the understanding for exercise and health, the actual and given condition of exercise participation and facilities was used for this study. 330 Aged women (over 60 year-old) who live in Seoul city were answered the Questionaire. Following conclusions were obtained were obtained : 1. Aged women's main daily works are managing house hold duties, attending a lecture in College for elderly, Seeing and Hearing of T. V. or Radio. And their Leisure activities are very simple (not various) and Static, for example seeing and Hearing of T. V. or Radio, gardening, reading, chess and Korean playing cards etc. 2. Aged women are very interested in Health and they point out illness and lack of exercise as a factor of weakness. Furthermore they understand the necessity of exercise for health and their daily life in old age, and also have a lot of intention to do exercise. 3. Exercises that aged women are enjoying or want to enjoy are taking a walk, mountain climbing, physical exercises, Aerobic dance, Badminton, and Jogging. 4. Almost aged women are doing exercise sometimes or usually, and also are seeing and hearing a T. V. or Radio for sports game. 5. Places that aged women are doing excercise are generally not well equipped place (e. g. medicinal water fountain, low hill, and around their house). Besides almost doing exercise alone or just with intimate friends and family. Club sports activities are not general. 6. As inconvinient factor for exercise, a lot of aged women pointed out the not specially equipped or established sports facilities for elderly, lack of number of equipment, and the long distance from home to facilities.

土性과 施肥水準 差異가 토마토의 生育에 미치는 影響

鄭淳柱,梁元模 順天大學校 1983 論文集 Vol.2 No.1

同一灌水條件下에서의 土性과 土壤水分變化, 土性과 施肥와의 關係, 土性과 施肥水準에 따른 토마토의 生育反應 等을 究明함으로써 收量增大및 品質改善을 위한 土性別 肥培管理 또는 관수체계 確立에 必要한 基礎資料를 모색하기 위하여 土性으로서 모래(砂土), 황토(砂壤土), 밭흙(壤土) 施肥水準으로서 無施肥區, 標準施肥區(N : 33kg, P : 22kg, K : 33kg/10a), 標準2倍施肥區의 各 處理에 영광 토마토를 供試하여 試驗을 遂行한 바 다음과 같은 몇가지 結論을 얻었다. 1. 土性別, 施肥水準別 土壤水分含量에는 差異가 없었으며, 電氣傳導度는 밭토양에서 높게 나타났고 모래와 황토에서 낮게 나타나 사토에서는 分施 그리고 황토에서는 增施하는 것이 바람직하였다. 2. Leaf water potential은 모래와 황토에서는 비슷하였고 밭흙에서는 낮았다. Stomatol resistence는 황토, 밭흙, 모래 順이었고 施肥水準間에는 無施肥區, 標準2倍施肥區, 標準施肥區 順으로 낮았다. 葉綠素 含量은 施肥水準이 높을수록 높았다. 3. 草長은 밭흙, 모래, 황도 順이었고 황토에서는 施肥量이 增加할 수록 草長이 크게 나타났으나 밭흙에서는 반대였으며 莖徑에는 處理間에 差異가 없었다. 4. 收量은 황토, 밭흙, 모래 順으로 높았으며 황토에서는 施肥水準이 높을 수록 收量이 많았고 밭흙에서는 그 반대로 나타나, 황토에서는 적절한 水分供給條件下에서 收量增大 可能性이 크게 認定되었고 土性에 따른 施肥水準과 施肥方法의 改善이 要求되었다. The purposes of this experiment were to investigate the influences of the soil texture and fertilizer levels on the growth responses and high yielding of tomato. Properties of the soil used were tested. The fertilizer levels consisted of no-fertilizer(control), standard fertilizer(N:33, P:22, K:33kg/10a) and double fertilizer of standard recommended by O.R.D in Korea. Young-gwang tomato seeds sowed at June, 7 and transplanted at July, 21. Soil moisture contents as affected by the soil texture and fertilizer levels showed no significance among treatments and the electric conductivity was high in upland soil but lowered in red soil and sand soil. So that the side fertilization in sand soil and the heavy fertilization in red soil were recommended. The leaf water potential were similar between the sand and the red soil, but lowered upland soil. In red soil interaction between the soil texture and heavy fertilization were affected to the leaf water potential. The stomatal resistance among the fertilizer levels was highly showed in order of no fertilizer, double fertilizer of standard and standard fertilizer. Chlorophyll contents in the leaf among the treatments were increased with increasing the fertilizer levels. Plant hights were observed highly in order of upland, sand and red soil, but the stem diameter showed no significant difference. In red soil plant hights increased with increasing fertilizer levels but adversed in upland soil. The high yield were observed in red soil and increased with heavy fertilization but vice versa in upland soil. Thus, the high yield potential was demonstrated in the red soil under appropriate water supply, however, improvements of fertilization with the soil texture and irrigation methods were required. Further trials should be followed about the cultural time, irrigation methods and other nutrient combinations in detail.

The radiopacity of six composite resins, three resin luting cements and ten filling materials were studied. The purpose was to obtain an indication of radiopacity value of different brands within each of these groups of materials and to show differences in radiopacities of filling materials and natural tooth structures. On radiographs, the optimal densities of standardized samples were determined by computer imaging system and radiopacity values of the materials were expressed in millimeter equivalent aluminum. Within the groups of materials studied, there was considerable variation in radiopacity. The composite resins of P-50, Z100 and Prisma AP.H displayed much higher radiopacities than aluminum. Panavia resin cement was shown to be similarly radiopaque to aluminum. Generally, the radiopacity of base and filling materials appeared to be higher than that of the enamel and dentin. If materials with substantial difference in radiopacity are used in combined applications for restorative treatment of teeth, lower radiopacity can interfere with the diagnosis and detection of gaps near the restoration.

It seems inevitable for residential buildings to be high-rise and allocated near traffic roads due to the crowdedness in urban areas. Acoustic environments in those areas have been seriously deteriorated by the increase of traffic vehicles. But sound barriers have a limitation in controlling noise due to diffraction noise from sound barriers. Hence sound barrier is not effective to protect the high-rise apartment from traffic noise. This work aims at evaluating characteristics of noise reduction according to the tunnel section shapes by using 1/5 scale model. We carried out a number of field measurements for 1/5 scale model of noise barrier tunnels with various sectional shapes. The results were as follows 1) The level difference was ranged from 0㏈ to 1.2㏈ according to the opening in the ceiling 2) The level difference was ranged from 0.4㏈ to 2.3㏈ when sound-absorbing materials were increased up to 45% of all surface areas. 3) There was generally good agreement between prediction results and the measurement results.

Objectives : The purpose of this study was to investigate the stress coping strategies and psychological charactehstics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. Methods : Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. Results : From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than nonnal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation, In the SCQ of somatization disorder patients, we observed generallylower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. Conclusion : These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.
