When channel catfish was injected with Cd and Zn chloride, the liver of the Cd-treated channel catfish was transiently activated to synthesize metallothionein(MT) mRNA and MT-like proteins. The poly(A)^+ mRNA of about 400 bases long was detected in the Cd-treated channel catfish liver with synthetic DNA probes (27 mer), which were conserved sequences in rainbow trout MT cDNA and human MT cDNA, by northern blot hybridization experiment. Amount of the mRNA from Cd treated channel catfish liver was enough to detect translation products in vitro, using the rabbit reticulocytelysate cell-free translation system. These translation products were MT-like proteins, which were about 6.5 kD in size on SDS-PAGE.

The demand for electric vehicles powered by lithium-ion batteries is continuously increasing. Recovery of valuable metals from waste lithium-ion batteries will be necessary in the future. This research investigated the effect of reaction temperature on the lithium recovery ratio from hydrogen reduction followed by water leaching from lithium-ion battery NCM-based cathode materials. As the reaction temperature increased, the weight loss ratio observed after initiation increased rapidly owing to hydrogen reduction of NiO and CoO; at the same time, the H₂O amount generated increased. Above 602 ℃, the anode materials Ni and Co were reduced and existed in the metallic phases. As the hydrogen reduction temperature was increased, the Li recovery ratio also increased; at 704 ℃ and above, the Li recovery ratio reached a maximum of approximately 92%. Therefore, it is expected that Li can be selectively recovered by hydrogen reduction as a waste lithium-ion battery pretreatment, and the residue can be reprocessed to efficiently separate and recover valuable metals.

The quality of steel produced from scrap can be adversely affected because of the buildup of tramp elements in recycled scrap. The tramp element of greatest concern is copper because of its effect on steel quality, even in small percentage quantities. In this study, possibility of removal of copper from ferrous scrap by using $Cl_2$ gas is experimentally examined in a small size experimental apparatus. Synthetic ferrous scraps containing copper were reacted with $Cl_2$ gas in various atmosphere. The copper was chloridized and evaporated, whereas iron was oxidized and was not reacted with Cl2 and oxygen mixture gas.

한국농수산대학 장기현장실습장 선정기준에 관한 기초연구 - 농수산비즈니스전공을 중심으로 -

이소영,신용광,김종숙,Lee, S.Y.,Shin, Y.K.,Kim, J.S. 국립한국농수산대학교 교육개발센터 2018 현장농업연구지 = Journal of practical agricultural resear Vol.20 No.2

농산업환경변화에 따라 농수산비즈니스 영역은 확대되고 있다. 한국농수산대학의 신설학과인 농수산비즈니스 학과의 장기현장실습 방향은 생산뿐만 아니라 생산이외의 분야까지 검토될 필요가 있다. 본 연구에서 검토한 기존의 장기현장실습장 현황 및 신설학과에 적합한 장기현장실습장 선정 방향은 다음과 같다. 먼저, 기존의 장기현장실습장은 단일품목 중심의 경영, 생산·가공·서비스 영역의 연계 미흡, 개별경영체 중심의 경영으로 요약할 수 있다. 그러나 새로운 가치 창출을 농업성장의 근원으로 보는 사례경영체는 가치창출의 다각화, 수평적 계열화, 법인체 경영을 통한 기업가적 경영, 지역농업연계를 통한 지역활성화 선도경영으로 요약된다. 따라서 신설학과의 장기현장실습장 선정 방향은 수평적 계열화를 통한 가치창출 경영, 농산업부가가치 창출에 필요한 기업가 정신을 구축한 농산업경영인 발굴, 기존 생산중심실습장과의 연계 방안 모색이 필요하다고 판단된다.

Recently, there is a growing interest in housing policy to prepare for the aging society. The purpose of this study is exploring the factors that explain housing consumption and adjustment of pre-retirees after retirement. 1,351 samples were collected from A bank and analyzed. There categories of housing consumption adjustment were considered including downsizing, maintain, and upsizing. Gender, educational level, housing size, housing type, asset size, and willingness to work after retirement were examined to see if they can explain the housing consumption adjustment of pre-retirees using orderd- probit model. The finding of this study is that housing size, asset size, and willingness to work after retirement statistically significantly explain the housing consumption adjustment. At specific, firstly, if the current size of the housing is relatively large, it is highly likely to downsize housing after retirement. Second, pre-retiree whose assets exceeded 1 billion won were more likely to scale up housing than assets of over 300 million to less than 500 million won. Lastly, unless there is absolutely no willingness to work after retirement, it is indicated that it intends to up-sizing consumption rather than down-sizing adjustment. The results of this study can provide useful information for the housing policy in order to prepare for the (post) aged society.

A large amount of Nd-Fe-B magnet scraps are generated during magnet manufacture process. In this study, selective chlorination of the rare earth elements by hydrogen chloride gas which obtained from the pyrolysis of polyvinyl chloride (PVC) was investigated. In thermogravimetric analysis, drastic weight loss was occurred at about 500 K and 710 K. At the isothermal experiments, the weight loss reaches about 30% above 673 K. XRD patterns characterized that after each experiments, ${\alpha}$-Fe, Nd oxychloride, Nd chloride, and Fe chlorides were formed, and the leaching residues remain only ${\alpha}$-Fe. The yields of Nd, Dy, and Fe for the isothermal experiment were increased with temperature and peaked at 873 K. As PVC ratio increased, the yields of Nd, Dy and Fe were also increased.

This paper investigated monthly meal composition and type of foods prepared for Dalye (ancestor rituals) over a period of 1 year based on the records in Sakmangdalye-deungnok and reviewed the ingredients for Dalye foods. From the results of our survey, 19 to 20 dishes were served in Sakmangdalye. 24 to 25 different foods were served in Sakdalye. Foods for Sakdalye consisted of Silkwa, Jogwa-Gwapyun, Jeongkwa or Suksilkwa, Hwachae-Sujeonggwa, Tteok, Cho, Jeonyueo, Sugyuk, Jjim, Hwe, Po, Sikhye, Tang, main dish-Guksu or Mandu, and Jang. Ingredients used in Sakmangdalye were recorded in a very integrated and simple manner in Sakmangdalye-deungnok. All ingredients were categorized into three groups: Kwasil (Fruits), Byeongmisikseung (Rice cakes etc.), and Muyeok (purchases). Sakmangdalye-deungnok was helpful in consulting dishes and ordering ingredients when a table for Dalye was set. Moreover, it was written simply enough so those who were in charge of preparing food could easily understand. This paper establishes Sakmangdalye-deungnok as one of the key materials for Royal Cuisine.

Purpose : Rotavirus is the main cause of infantile diarrheal disease worldwide. The purpose of this study is to assess the difference between clinical manifestations and feeding or delivery methods in healthy full-term neonates and those with nosocomially-acquired rotaviral infection. Methods : The study was conducted on 348 babies who were delivered in Dongguk University Kyongju Hospital from Jan 1 to June 30 in 2001. Stool specimens were collected from clinically symptomatic neonates. We studied the rate of positive stool rotazyme ELISA tests and positive symptoms. We compared the frequency of clinical manifestations according to the feeding methods [breast feeding(BF) or formula feeding(FF)] and the delivery methods[normal vaginal delivery(NVD) or Cesarean section(C/sec)]. Results : Rotavirus was detected in 152 of 348 babies. The rate of positive rotazyme ELISA test was 43.7% in healthy full-term symptomatic neonates. The most common symptom of rotaviral enteritis was mild fever; the others were watery diarrhea, abdominal distension, vomiting, delayed weight gain, irritability, poor oral intake and dehydration. Compared with FF neonates, BF neonates have lower frequency of symptoms, especially watery diarrhea, delayed weight gain and poor oral intake. The symptomatic frequency was higher in FF and NVD neonates than BF and C/sec. Conclusion : The symptoms of rotaviral enteritis were less frequent in BF or C/sec delivered neonates. BF appeared to alleviate the rotaviral enteritis but further studies are needed. The cause of the lower frequency of symptoms in C/sec delivered neonates was unknown.

Small cell carcinoma usually occurs in lung, but extrapulmonary small cell carcinomas can occur in any sites of body. Most sites of extrapulmonary small cell carcinoma reported were esophagus. And small cell carcinomas occurred in head and neck area were reported rarely. Extrapulmonary small cell carcinoma could be diagnosed when there is no evidence of primary lung lesion on chest X-ray, CT scan of chest and bronchoscopy. The authors experienced a case of small cell carcinoma of left submandibular lymph node in 64-year-old male patient. Biopsy specimen showed poorly differentiated carcinoma but immunohistochemical study showed small cell carcinoma. The chest X-ray and CT scan of chest showed no evidence of primary lung lesion. The patient received chemotherapy(etoposide plus cisplatin) and concurrent chemoradiotherapy using weekly taxol which resulted in good clinical remission. He is still alive 8 months after diagnosis without evidence of lung disease. We report our case with a brief review of literatures.
