N/A Background : Because there aremany different reporting results about the etologies of solitary pulmonary nodules (SPNs), we cannot know the exact incidence of each causative disease. SPNs have a good prognosis relatively even if it is a malignant lesion. In Korea, where there is a high incidence of pulmonary tuberculosis, the differential diagnosis of SPNs should be performed. Methods : Among 351 patients who visited Wonju Chistian Hospital for SPNs in chest x-ray between 1982 and 1989, we evaluated 74 patients in whom the causes of SPNs could be elucidated by sputum AFB study, cytology, histolgic study, chest of solitary pulmonary nodule (SPN) seen at the Wonju Christian Hospital from 1982 to 1989. The followings were obtained. 1) The malignancies of SPN 74cases were 25 cases (33.7%). The primary lung carcinomas were 24 cases : The epidermoid carcinomas of these were 11 cases (45.8%), metastasis I case, tuberculoma 42 cases, and the other 7 cases. 2) The age distribution of benign lesions was from 19 to 73 years old with the mean age of 46 years old, and the age distribution of malignancies was from 17 to 77 years old with the mean age of 57 years old. The 23 cases (92.0%) of malignant nodules were more than 40 years old. The malignant frequency of SPN in a group of age more than 40 years old was 40.3% and in a group of age less than 40 years old, it was 11.7%. The malignant frequency was directly proportional to the increase of age(p<0.05). 3) The 3 cases of SPN were detected accidentally during physical up, all were benign. The 14 cases were detected during the evaluation of other diseases, 12 cases were benign. The 23 cases (40%) of 57 cases were symptomatic. Chest pain, dyspnea, and weight loss frequency in a group of less than 3cm in size was 11.9% and in a group of less than 3cm in size, it was 62.5% (p<0.05). 6) Calcifications were noted in 15 cases of 74 cases on the plain films, all were 7 central types, 7 diffuse types and 1 popcorn type. One of malignant cases had calcification on the chest CT scar. Among the 59 cases with non-calcified nodules, 25 cases were malignant (42.3%). The mean Hounsfield Unit of benign lesions was 182.5U and that of malignancies was 94U, there was a statistical difference between both groups(p<0.01). 7) The 21 cases (50%) of tuberculomas were located at the apicoposterior segment of upper lobe or the superior segment of lower lobe, but the 7 cases (28%) of malignancies were located at above sites. 8) The diagnostic accuracy of sputum study was 9.4% and that of fiberoptic bronchoscopy (FOB) was 33.3%. The diagnostic accuracy of transbronchial lung biopsy (TBLB) and transthoracic needle aspiration biopsy (TTNAB) was 57.4%. The percentage of primary lung cancer among SPNs which are larger than 3cm in size, occurring in the age of older than 40 years old and with no calcifications on radiologic examintion should be suspected as malignancies and diagnosed with sputum study, fiberoptic bronchoscopy, TBLB, and TTNAB.

본 연구는 고도 차이 혹은 수송 거리의 차이가 한우(거세우 및 암소)의 도체특성, 표면육색 및 혈중 cortisol 농도 변화에 미치는 영향을 검토하기 위해 실시되었다. 공시동물은 총 190두로 이중 거세한우는 118두 암소는 72두였다. 자료는 사육 고도(100, 200, 300, 400 및 500m) 혹은 수송 거리(50, 100, 150, 200 및 250 km)에 따라 분석하였다. 사육 고도의 차이가 거세한우 및 암소의 육량 및 육질 형질 변화에 미치는 영향은 적었으며, 수송 거리의 차이가 거세한우 및 암소의 육량 형질에 미치는 영향은 없는 것으로 나타났다. 또한 수송 거리의 차이가 거세한우 및 암소의 근내지방도, 육색 및 지방색에 미치는 영향과 사육 고도 혹은 수송 거리의 차이가 거세한우 및 암소 등심의 명도, 적색도, 황색도, 선명도 및 색상색에 미치는 영향은 낮은 것으로 나타났다. 암소의 경우 사육고도 100m에서 200m에 비해 등심의 명도가 증가되었으며(p<0.05), 거세한우의 경우 수송 거리 250km 그리고 암소의 경우에는 200km에서 등심의 명도가 낮아지는 경향을 보였다. 한편, 혈중 cortisol 농도는 낮은 사육 고도에 비해 높은 사육 고도에서 낮아지는 경향을 보였으나, 통계적인 유의차는 없었다. 수송 거리가 거세한우 및 암소의 cortisol 농도에 미치는 영향은 없었다. 따라서 본 연구의 결과에서 사육 고도 혹은 수송 거리가 한우의 생산성에 미치는 영향은 적은 것으로 판단된다. The purposes of the study were to examine the changes in carcass traits and surface meat color, and cortisol concentration by different altitudes and shipping distances for steer and cow. The experimental animals were shipped from Kangwondo, Kyunggido, Choongchungdo, and Kyungsangdo to Wonju LPC. The animals were examined for yield traits, quality traits, carcass grade, lightness, redness, yellowness, croma value, and cortisol concentration by different altitudes and shipping distances. The results showed that the carcass traits of steer like back fat thickness were not different by shipping distances of 100km, 150km, and 200km. However, the fat thickness was higher in steers shipped from 250km than 100km, 150km, and 200km distance. Rib- eye area was reduced significantly in 200km and 250km than 50km. Yield index and yield grade were significantly low in 250 km than 50-200km. However, meat color, fat color, texture, mature, and quality grade had no differences between shipping distances. Marbling score was not different in 50-200km. However, the marbling score in 250 km was significantly lower than that of 50 km. In case of surface meat color by shipping distance, redness, yellowness, chroma value, and hue-angle were not different in shipping distance of 250km. The lightness had similar result in 50-200 km. However, in case of 250 km the lightness was significantly low. The REA of cow carcass by shipping distance had no differences by shipping distance. The BET had similar results in 50-150km. However, it had significantly thick in 200km. The yield index and yield grade had no differences in 50-150km. However, yield index and grade were significantly low in 200km. The carcass trait of cow had no differences in all items by shipping distance. Although the carcass traits and the BET for steer by altitude had no differences between 100, 200, 300 and 500m, but those were significantly thick in 400m. And the yield index and the yield grade at altitude 400 m were lower than that of other altitudes. The quality traits and the quality grade had no differences between 100, 200, 300, 400, and 500m altitudes. The yield traits, quality traits, yield grade, and quality grade had no significant differences by altitudes. In case of yield index of cow for 300m was low than the cases of 100m and 200m. The surface meat color for steer and cow had no differences by altitudes. However, the lightness of cow had positive result in 100m than 200m and 300m. In case of steer and cow the cortisol concentration by shipping distance was high as the shipping distances were longer. However, the cortisol concentrations of steer and cow by altitudes were decreased as the altitudes were increased. From the above results carcass traits and carcass grade were decreased and the cortisol concentration was increased as the altitudes were decreased for steer and cow.

화재 원인과 관계자 책임에 관한 사례연구

화재가 발생하면 화재 원인을 규명하기 위해 국가기관이 획일적으로 현장을 감식하여 증거를 수집하고 감정을 통하여 화재 원인을 규명한다. 국가기관의 화재 원인 규명은 결론이 같아야 하고, 다를 경우 정보를 공유하여 사실관계를 증명하여야 한다. 하나의 화재 사례를 분석한 본 연구에 의하면, 화재 원인에 따라 책임 관계가 달라지고 가해자와 피해자로 나뉘기 때문에 정확한 화재 원인 규명을 위해 감식과 감정을 통하여 오류를 최소화할 수 있다. 오류가 있다면 재조사할 수 있는 법령을 제정하여 국민의 억울한 피해가 없도록 하여야 하며, 증명된 증거만으로 화재 원인을 판단하여야 하고, 보충적으로 전문가로 구성된 민, 관, 산, 학이 현장을 조사할 수 있는 화재조사 제도의 도입이 필요하다. In the event of a fire, a national agency inspects the scene, collects evidence, and assesses and identifies its cause. In the investigation of the cause of fire, the state agency involved in the investigation should offer consistent conclusions. In case of conflicting conclusions, the facts of the case must be established by sharing the relevant information. The findings of this study suggest that the responsibilities of the respective parties involved in a fire accident vary depending on the cause of the fire. The cause of the fire also affects the determination of which parties are at fault, and which parties are the victims. Therefore, errors should be minimized through scene investigation and assessment to accurately determine causes of fire. A law needs to be enacted that provide for re-investigation in case of an erroneous investigation. In addition, the cause of a fire should be determined solely based on substantiated evidence. It is also necessary to introduce a fire investigation system in which experts from the public sector, the private sector, the academia, and the industries are allowed to investigate the scenes of fire.

N/A To evaluate the postoperative long-term quality of life(QOL) in patients who underwent total gastrectomy(TG) for gastric cancer, we performed a questionnaire survey of their daily life (78 patients) and the general status. In the questionnaire survey, over 80% of the patients were good or fair in QOL. However, over a half of them including the patients who has passed more than five years after TG, have suffered from' vairous postgastrectomy complications which reguired pertinent treatments. It should be emphasized that close and long-term follow up with adequate treatments in accordance with the possible postoperative complications is essential for keeping the QOL of patients in good condition who underwent TG.

Rape constitutes the most under-reported crime in the United States, particularly among Asian-American women. Unreported rapes impede intervention, victim supports, and the social recognition and information necessary for policy-making. Addressing these problems, this study explores ethnic cultural impediments to Korean-American women`s disclosure of rape, using both qualitative and quantitative research methods. Qualitative data for this study were collected between 1994 and 1999 from in-depth interviews with 36 Korean-American women and three counselors working in Korean-American communities. Quantitative data were collected in May of 2000 from self-administered surveys with 219 Korean-American women. Correlation analyses of the survey data suggest that the women`s concerns about marriage would decrease their likelihood of reporting a rape incident if it occurred. Marital concerns included the possibility of decreasing marriage prospects for single women, and concerns of potential conflicts or even diss olution of marriage, if already married. In contrast, the women`s concerns about security would increase their likelihood of reporting a rape incident if it occurred. The marital concerns reflected the power of ethnic cultural strictures on female sexuality. The women cared about Korean or Korean-American mens` demand for a woman`s untainted virginity and sexual commitment to one husband. The women were also concerned about marriageability, because of the importance of marriage as a providing for a woman`s legitimate sexual expression, child-bearing, security and her social or symbolic status. The power of Korean cultural models was enforced by a set of ideological, institutional, and material conditions. They included Confucian and Christian restrictions on female sexuality and ways of living, preference for intra-ethnic marriage, male-oriented marriage for the purpose of raising a family, and Korean-American women`s ethnic and class statuses. In conclusion, Korean-American women`s likelihood of disclosing a rape incident are discouraged by the masculine ideals emphasizing the value of a woman`s sexual purity in marriage. These findings suggest that social service providers for a Korean-American female rape victim should be sensitive about incorporating her Korean or Korean-American male partner into the process of providing support for the victim. These findings also suggest that it is necessary to change the masculine strictures on female sexuality in order to encourage women to disclose the occurrence of a rape. A new and alternative cultural norm of a Korean American woman`s sexuality would enable her to express her sexual subjectivity.

Bone graft had been investigated previously to restore bone defects in orthopedics. The purpose of this study was to investigate the efficacy on new bone formation in bone autografts by treatment of implants. Cortical bone autografts were transplanted to midshaft of diaphyseal fibulae of 9 rabbits which were divided in 3 groups according to the treatment method of implants. Cortical bone implants for graft were treated with 3 different methods; freezing, freeze-drying, defat-freezing. Autografts were achieved by cross-transplantation method to bilateral fibulae of the presented rabbits after implant treatment procedures. The grafted regions of fibulae of all groups had been radiographed biweekly for 16 weeks to observe new bone formation and union between donor and recipient bone in the grafted region. Bone alkaline phosphatase (BALP) in all groups was evaluated biweekly till the end of the experiment to determine osteoblast activities. Unions of the experimental grafted regions were observed at 83% (5 of 6 cases) of freezing, 17% (1 of 6 cases) of freeze-drying and 67% (4 of 6 cases) of defat-freezing autografts, respectively. BALP was increased over 100% after 2 weeks of graft procedures in all union cases (all cases in freezing group and in defat-freezing group, and 1 of 3 in freeze-drying group, respectively), then gradually decreased from 4 th week of graft to 16 th week. In non-union cases, there is no significant variation in BALP value until the end of experiment. It is speculated that defat-freezing method of treatments of implants is more safe to preserve the osteogenic ability in autograft than freeze-drying method.

Koreans prefer Korea beef to imported beef. The volume of imported beef is being increased in Korea. Consumers preference may be changed when they consume the imported beef more. The purposes of this study are to analyze the changes of the Koreans`` preference and perception to Korean beef and imported beef. Koreans who are living in Korea prefer Korean beef to imported beef. However, Koreans who are living in U.S.A. may prefer U.S. beef or keep neutral between the two kinds of beefs. Questionnaire were given to Koreans who were living in Korea and U.S.A. from January to April in 2014. SPSS 18.0 was used for the analyses. T-test was used for comparative analysis by living country about beef and multiple regression analysis was used for analyzing impacts of age and period of reside in United States to quality evaluation about Korean beef and U.S. beef. In the result, Korean consumers had differences in all perception variables about U.S. beef by living country, but hadn``t in Korean beef. And Korean consumers living in Korea and United States evaluated that Korean beef had better quality than U.S. beef. Finally, only period of reside in United States had positive impacts to perception of U.S. beef quality. Korean beef should try to keep high quality and image. Government need to active support and intensive control beef traceability system and origin labeling. Imported beef market may be expanded in the future. So prepare countermeasure for low-grade Korean beef about increasing of the imported beef in Korean market.
