The purpose of this study is to analyze the actual condition of job demand in the agricultural and fishing villages in Buan-gun. For the actual condition analysis, the target companies were identified based on the administrative data of Buan-gun, and a field survey was conducted. According to the results of the study, there is demand for jobs, and simple labor jobs at the basic wage level were preferred. In order to vitalize these jobs, it was expected to establish governance by forming an intermediate support organization for jobs in agriculture, fishing, and rural areas, and then the local governments would actively participate in job support. Moreover, in order to vitalize jobs in Buan-gun, an intermediate support organization for jobs should be established to operate practical and hands-on programs for the manpower management between the demand and supply, and those who are looking for a job, develop direct dealing businesses and stay-type tourism products, create jobs through connecting with agricultural process field, and actively foster the operation body of the social agriculture and healing agriculture. In addition, new jobs should be created. In other words, it is possible to provide jobs of helping services for teenagers, elderly people, and children of foreign families, and create jobs related to various commentators, performance group, or playing culture. It is possible to create new jobs in the field of production, processing, distribution, and service of agricultural products by providing farmland through developing idle land and may create jobs such as farming start-up, distribution of agricultural products, agent of agricultural work (drone, agricultural work, agricultural machine work, etc.), using idle facilities in the region (facility house or common facility), hands-on and accommodation facilities, processing facilities, restaurants, or markets. In particular, it is hard for young people to secure initial investment for start-up company, so the intermediate support organization should provide information and support establishment of business plan linked with the government’s youth start-up support project.

난소절제에 의하여 유도된 생쥐 골다공증 모델을 이용하여 모싯잎 분말과 모싯잎 추출물의 골다공증에 대한 효과를 관찰하고자 농도별 모싯잎 분말과 모싯잎 추출물을 12주간 자유 섭취 또는 경구투여 하였다. 실험종료 후 micro-CT를 이용하여 경골의 골밀도, 구조적인 변수들 및 골 형성과 골흡수 관련 인자들인 혈청 내 osteocalcin 함량과 CTX-1의 변화를 관찰하였다. 모싯잎 분말 급여군과 모싯잎 추출물 투여군은 12주째에 실험적 골다공증 모델 생쥐의 혈청 내 골 형성 인자와 골 흡수 인자를 감소시켰으며, 골밀도 등골다공증 관련 치밀뼈와 해면뼈의 구조적 변수들을 개선한 것으로 보아 골다공증 예방에 매우 효과적인 기능성 식품으로 활용할 수 있으리라 생각된다. The objectives of this study were to investigate the effects of Ramie leaves (RL) on bone metabolism in ovariectomized (OVX) mice. Female mice weighing 20∼25 g each were assigned to six experimental groups: Sham-operated group (Sham group), OVX control group (OVX group), OVX mice fed calcium-free diet with 5% (RL5% group) or 10% (RL10% group) RL supplemented diet, and administered ramie extract (RLext group, 1,000 mg/kg, p.o.). After 12 weeks, all experimental groups demonstrated significantly increased bone mineral density and trabecular thickness, and the RL10% and RLext groups showed significantly increased bone volume/tissue volume and trabecular number. This study attempted to use a physiological analysis method to analyze the serum osteocalcin and C-telopeptide contents of type Ⅰ collagen (CTX-1). The osteocalcin concentration was significantly reduced in both the RL5% group (28.6%) and RL10% group (36.5%) compared to the OVX group. The CTX-1 concentration was significantly reduced in both the RL5% group (43.5%) and RL10% group (42.9%) compared to the OVX group. These results suggest that RL might improve the structural parameters of trabecular bone and bone mineral density, as well as reduce bone formation and bone resorption factors. Therefore, RL could be applied as a functional food material for prevention of osteoporosis.

Takayasu 동맥염과 특발성 혈소판 감소성 자반증은 두 질환 모두 발병원인 및 병태생리에 있어 자가면역성이 중요한 역할을 한다고 할 수 있다. 본 저자들은 Takayasu 동맥염과 특발성 혈소판 감소성 자반증이 동반된 57세 남자 증례를 보고하는 바이다. 본 증례 남지는 1년전 특발성 혈소판 감소성 자반증을 전단받았다. 복통 및 혈변배설을 주소로 내원한 환자는 좌측 위팔동맥(Left brachial artery)의 맥박이 감소된 소견을 보였으며, 청진 소견상 복부 잡음(abdominal bruit) 소견 을 보였고, 흉복부 컴퓨터 단층 촬영 및 3차원 대동맥 혈관 재구성 컴퓨터 단층 촬영 소견 상 좌측 쇄골밑 동맥(left subclavian artery), 흉복부 대동맥(thoracoabdominal aorta), 복강 동맥(celiac trunck), 상 창자간막 동맥(superior mesenteric artery)의 다발성 혈관염 소견을 보여 Takayasu 동맥염에 합당한 소견을 보였다. 고용량 스테로이드 치료 후, 환자의 임상적 증상과 혈침속도가 호전되었다. Takayasu`s arteritis (TA), a chronic inflammatory arteriopathy of unknown etiology, lead to both stenotic and ectatic changes, particularly occlusion. The common sites of involvement are the aorta and its main branches, and pulmonary artery. A specific etiology for TA has not been found. Autoimmunity has been found to play an important role in TA, and association with various autoimmune disorders has been reported in selected cases. There is no case report that TA coexists with idiopathic thrombocytopenic purpura (ITP). We report a case of TA associated with ITP in a 57-year-old man. He suffered from ITP 1 years earlier. On admission, the patient presented with periumbilical abdominal pain. TA diagnosed on the basis of decreased pulsation of the left brachial artery, bruit over the abdominal aorta and multifocal vasculitis in the left subclavian artery, thoracoabdomianl aorta, celiac trunk and superior mesenteric artery on thoracoabdominal computerized tomography and 3-D aortic arch reconstruction computerized tomography. Following the high dose steroid therapy, his clinical symptoms improved and erythrocyte sedimentation rate decreased.

샘낭암종은 선암의 조직학적 변형으로서 대부분 침생, 눈물샘 또는 다른 외분비샘에서 발생하며 호흡기계에 드물게 발생하는 경우에도 주로 기관과 주기관지에 발생하며, 주 기관지 이하의 말초에서 발생하는 경우는 매우 드물다. 본 저자들은 좌측 아래엽 위구역 기관지의 페쇄를 초래한 샘낭암종으로 진단된 31세 남자 증례를 보고하는 바이다. 내원 1개월 전부터 시작된 마른 기침과 심호흡시의 흉부 불쾌감으로 내원한 환자는 흉부 전산화 단층촬영에서 좌측 아래엽에 경계가 명확하고 분엽화된 침상 종괴가 관찰 되었고, 종괴는 좌측 아래엽 위구역 기관지를 폐쇄시키고 있었으며, 좌측 페동맥의 좌측 아래엽 위구역 분지를 침범하고 있었다. 기관지내시경에서 좌측 아래엽 위구역 기관지는 혈액 공급이 풍부한 종양으로 폐쇄되어 있었다. 조직검사에서 특징적인 샘낭암종 소견이 관찰되었고, 원격전이 평가를 위한 검사 후 Stage IB로 병기 결정되었다. 환자는 수술적 치료를 적극 권고하였으나, 치료를 거부하고 퇴원하였다. Adenoid cystic carcinoma is rare malignant tumor that usually arise from major salivary gland, and can be found in lower respiratory tract. Adenoid cystic carcinoma of the lower respiratory tract usually arise in the mainstem bronchus and often presents as an endobronchial mass lesion causing bronchial obstruction with atelectasis and pneumonia. But, tumor originated from more distal branch of bronchus is extremely rare, and can be confounded with other primary lung malignancy. Adenoid cystic carcinoma is considered to be a low grade malignant neoplasm and its characteristics are infiltrative nature with tendency of local recurrence and long natural course. Treatment modality and prognosis is different from other lung malignancy. We report a 30 year old male patient with adenoid cystic carcinoma that found in left lower lobe bronchus and will discuss the biologic behavior of this unusual primary lung tumor as it relates to management considerations.

An abattoir study on the abdominal fat necrosis in adult cattle was performed pathologically. Grossly, masses of fat necrosis were leekgreen in colour, lobulated on the cut surface, and saponificated in the texture. These necrotic adipose tissues infiltrated usually into neighboring parenchymal organs including intestines and pancreas, leading to fibrosis or atrophy of them. Histopathologically, necrotic fat cells contained acidophilic, opaque, amorphous substance or basophilic fibrillar or granular minerals in their cytoplasms. The lesions of fat necrosis were divided by fibroconnective tissue. With increase of the severity, necrotic fat cells fused each other and then formed fat cysts. In this severe lesion, necrotic fat cells were partialy or completely replaced by macrophages. Multinucleated giant cells were scattered in this lesion. Interestingly, small artery in the lesion of fat necrosis revealed severe thickening of internal elastic membrane. Severe fibrosis was observed in or between the outer longitudinal and inner circular muscular externas causing segregation, degeneration and necrosis of muscle fibers. The nerve cells of Auerbach's and Meissner's plexuses surrounded by fibrosis were degenerated or necrotic. In addition, necrotic fat cells infiltrated into the pancreas, resulting in pancreas atrophy. From these results, it is speculated that fat necrosis might compromise intestinal movement due to necrosis of muscular externa and ganglion cells of Auerbach's and Meissner's plexuses.

This study was conducted to analyze the relationship between the occurrence of mastitis and the conformation of udders, teats, and teat tips of Holstein cows raised in Korea. Udders, teats, and teat tips were categorized by their conformation and the teat length, teat diameter and the distance from the tip of teat to the ground of 259 cows were measured. The most common shapes of udder, teats and teat tip were milking machine udder (27.4%), U-shaped teats (53.9%) and disk teat tip (53.8%), respectively. Mean teat length and diameters were 4.78 cm and 3.11 cm, respectively. The length and the diameter of front teats were significantly longer and wider than those of rear teats. However, the distance of the tip of teats to the ground was similar between front teats $(50.5{\pm}7.51cm)$ and rear teats $(50.7{\pm}8.83cm)$. The average daily milk yield was 26.4 kg/day, and the highest milk yield was observed from cows with large udder shape and above 4th lactation.

This study investigated the effects of the alkaline detergent and acid rinse used for cleaning milking machines on the rubber composition of the newly-developed teat cup liners. The samples prepared for use in the clean-in-place process were analyzed by ultraviolet spectrophotometer, ion chromatography and liquid chromatography. In the absorption spectrum of the first sample solution, the form of absorbance or absorption peak was largely different, compared to the absorption spectrum of alkaline detergent alone, but in the absorption spectra of the second and third sample solutions, the absorbance decreased, which was similar to the absorption spectrum in the pure acid detergent. In the ion chromatogram, two main peaks only, which might be shown by the pure alkaline detergent alone, were measured. In the liquid chromatograms, however, new peaks were observed in addition to the two main peaks caused by the pure alkaline detergent alone, which suggested that various molecular materials were created or eluted from the liner by the reaction with the alkaline detergent, but when washed with the acid detergent, any ion species were not produced. Therefore, we propose that an acid rinse should be applied, after cleaning the milking machine with the alkaline detergent.
