Prostaglandin A₂ (PGA₂)는 사람 골육종 세포인 U2OS 세포주에서 apoptosis와 heme oxygenase (HO)-1의 발현을 함께 유도하였다. PGA₂에 의한 apoptosis는 HO-1의 과도한 발현이나 HO-1에 대한 small interfering RNA에 의한 발현저하에 의하여 변동되지 않았으나 H₂O₂에 의한 세포사망은 HO-1의 발현 수준에 반비례하여 변동되었다. 또한 thiol antioxidant인 N-acetyl-L-cysteine (NAC)은 PGA₂에 의한 세포사망과 HO-1의 발현 증가를 모두 차단하였지만, non-thiol antioxidant인 butylated hydroxyanisole (BHA)과 ascorbic acid는 세포사망과 HO-1의 발현 유도를 차단하지 않았다. 이와 같은 결과들은 PGA₂는 산화성 손상에 의해서가 아니라 PGA₂의 thiol-reactivity에 의하여 apoptosis와 HO-1의 발현을 유도하며, HO-1의 발현은 PGA₂에 의한 apoptosis와는 독립적인 현상이거나 기능적으로 apoptosis 유도의 하부에 위치하고 apoptosis의 진행에는 기여하지 않을 것이라는 것을 시사해 준다. Prostaglandin A₂ (PGA₂), one of cyclopentenone PGs, induced both apoptosis and heme oxygenase (HO)-1 expression in U2OS cells. PGA₂-induced apoptosis was not perturbed by either over-expression or knock-down of HO-1, whereas H₂O₂-induced cell death was inversely modulated by the expression level of HO-1. In addition, N-acetyl-L-cysteine (NAC), a thiol antioxidant, blocked both apoptosis and HO-1 expression induced by PGA₂. But, non-thiol antioxidants like butylated hydorxyanisole (BHA) and ascorbic acid did not block either apoptosis or HO-1-induction. Taken together, these results suggest that PGA₂ induces both apoptosis and HO-1 expression, which are critically related to the thiol-reactivity of PGA₂, but not oxidative stress, and HO-1 expression may be independent or functionally located downstream of apoptosis by PGA₂ without contribution to apoptosis progression.

한국산 거미 목록을 최근 분류체계와 새롭게 추가된 분류군을 총망라하여 재정리하였다. 그 결과, 한국산 거미류의 수는 총 48과 281속 795종으로 조사되었으며, 이전 김과 김(2010)의 발표보다 2과 16속 69종이 많았다. 이전의 김과 김(2010)의 목록에서 이용된 분류체계와 비교해 크게 변동된 사항으로는 기존의 코리나거미과(Family Corinnidae)에 속하는 3개 속(Genus Cetonana 괴물거미속(개칭), Genus Paratrachelas 어리괭이거미속, Genus Trachelas 괭이거미속)과 2개 속(Genus Orthobula 십자삼지거미속, Genus Phrurolithus 도사거미속)이 각각 괭이거미과(Family Trachelidae)(신칭)와 도사거미과 (Family Phrurolithidae)(신칭)로 분리, 신설되었으며(Ramírez, 2014), 밭고랑거미과(Family Liocranidae)의 족제비거미속(Genus Itatsina)이 미투기거미과(Family Miturgidae)의 1속(Genus Prochora)에 하위 동종이명(synonymy)으로 편입됨(Bosselaers & Jocqué, 2013)에 따라 Prochora 속의 국명이 족제비거미속으로 개칭되었다. 또한 오소리거미과(Family Zoridae)가 미투기거미과(Family Miturgidae)에 하위 동종이명으로 편입되었으며(Ramírez, 2014), 기존에 미투기거미과에 속해 있던 1속(Genus Cheiracanthium 어리염낭거미속)이 미투기거미과로부터 분리, 신설된 장다리염낭거미과(Family Eutichuridae)(신칭)로 분류되었다(Ramírez, 2014). 그 밖에 속, 종의 단위에서 분류군 신설, 동종이명, 오동정 등의 분류 체계 변동 사항이 있었으며, 이를 본 목록에서 확인할 수 있다. 더불어 근래에 추가된 2종의 무자격명(Nomen nudum) 처리된 종과, 국립공원 생물종 목록집(2012)에 기재되었으나 논문으로 정식 발표되지 않은 미기록종 22종을 별도로 기술하였다. 한국산 거미류는 접시거미과(101종), 꼬마거미과(84종), 왕거미과(79종), 깡충거미과(73종), 그리고 늑대거미과(57종) 이하 순으로 종수가 많았으며, 위의 5과가 전체 종수의 약 50%(394종)을 차지하였다. 전체 795종 중 한국산 고유종은 173종(21.8%)이었고, 일본산 거미류와 512종(64.4%), 중국산과 497종(62.5%), 러시아산과 360종(45.3%), 대만산과 103종(13.1%) 동일종이었다. 또한, 구북구산(Palearctic region)이 80종(10%), 전북구산(Holarctic region)이 37종(4.7%), 그리고 세계공통종(Cosmopolitan species)이 13종(1.6%)으로 분석되었다. A revised new-version of the check list of Korean spiders, including recent systematic systems and new taxa, is presented in this paper. According to additional references in the last 5 years, a total of 795 species of 281 genera belonging to 48 families were checked in Korean spider fauna, and there are 69 species of 16 genera belonging to 2 families more than the previous check list(Kim & Kim, 2010). Typical examples of some changes in systematic systems of Korean spiders compared with the previous check list(Kim & Kim, 2010) are as follows : Two families, the family Trachelidae and the family Phrurolithidae, previously in the family Corinnidae are raised to family status(by Ramírez, 2014). In Korea, the family Trachelidae includes 3 genera(Gen. Cetonana, Gen. Paratrachelas, Gen. Trachelas) and the family Phrurolithidae includes 2 genera(Gen. Orthobula, Gen. Phrurolithus); The family Eutichuridae is raised to family status, which was previously in the family Miturgidae(by Ramírez, 2014). There is one genus(Gen. Cheiracanthium) in the family Eutichuridae in Korea; The family Zoridae is included as a junior synonym of the family Miturgidae(by Ramírez, 2014); The genus Itatsina is included as a junior synonym of the genus Prochora in the family Miturgidae(Bosselaers & Jocqué, 2013). One Pisaurid species(Dolomedes jirisanensis) and a Sparassid genus(Gen. Joopilia, Joopilia joopilis) are nomina nuda. Additionally, There are 22 unrecorded species, which was found by Korean National Park Research Institute(2012) but was not described as papers, check list of them is presented separately from the check list of Korean spiders in this paper. Linyphiidae(101 sp.), Theridiidae(84 sp.), Araneidae(79 sp.), Salticidae(73 sp.), and Lycosidae(57 sp.) spiders are the most in the Korean spider fauna, and species in that 5 families formed about 50%(394 sp.) of the whole Korean spiders. In zoogeographical distribution, Korean spider fauna was found containing 80 Pa, 37 Holarctic, 13 Co, and 173 Korean endemic species. And comparison with faunas of neighboring countries, 512 species of Korean spiders also live in Japan(64.4%), 497 species live in C(62.5%), 360 species live in Russia(45.3%) and 103 species live in Taiwan(13.1%).

Artificial reefs are widely used as important means of fishing ground creation for not only commercial fishing but also recreational fishing. The evaluation of artificial reef in this study was made based upon three steps, estimation of effective bulk void volume, catch analysis per unit reef volume and biomass estimation of attachment organisms on the reef. This method can be applied to both the evaluation for post-deployment management of the exist artificial reefs and for the preservation of fisheries resource at the artificial reef fishing grounds.

The purpose of this study was to develop a basic framework and criteria for evaluation of quality care provided to patients with the attributes of disease in the home care nursing field, and to provide measurement tools for home health care in the future. The study design was a developmental study for evaluation of hospital-based HCN(home care nursing) in Korea. The study process was as follows: a home care nursing study team of College of Nursing. Yonsei University reviewed the nursing records of 47 patients who were enrolled at Yonsei University Medical Center Home Care Center in March, 1995. Twenty-five patients were insured at that time, were selected from 47 patients receiving home care service for study feasibility with six disease groups; Caesarean Section (C/S), simple nephrectomy, Liver cirrhosis(LC), chronic obstructive pulmonary disease(COPD), Lung cancer or cerebrovascular accident(CVA). In this study, the following items were selected : First step : Preliminary study 1. Criteria and items were selected on the basis of related literature on each disease area. 2. Items were identified by home care nurses. 3. A physician in charge reviewed the criteria and content of selected items. 4. Items were revised through preliminary study offered to both HCN patients and discharged patients from the home care center. Second step : Pretest 1. To verify the content of the items, a pretest was conducted with 18 patients of which there were three patients in each of the six selected disease groups. Third step : Test of reliability and validity of tools 1. Using the collected data from 25 patients with either cis, Simple nephrectomy, LC, COPD, Lung cancer, or CVA. the final items were revised through a panel discussion among experts in medical care who were researchers, doctors, or nurses. 2. Reliability and validity of the completed tool were verified with both inpatients and HCN patients in each of field for researches. The study results are as follows: 1. Standard for discharge with HCN referral The referral standard for home care, which included criteria for discharge with HCN referral and criteria leaving the hospital were established. These were developed through content analysis from the results of an open-ended questionnaire to related doctors concerning characteristic for discharge with HCN referral for each of the disease groups. The final criteria was decided by discussion among the researchers. 2. Instrument for measurement of health statusPatient health status was measured pre and post home care by direct observation and interview with an open-ended questionnaire which consisted of 61 items based on Gorden's nursing diagnosis classification. These included seven items on health knowledge and health management, eight items on nutrition and metabolism, three items on elimination, five items on activity and exercise, seven items on perception and cognition, three items on sleep and rest, three items on self-perception, three items on role and interpersonal relations, five items on sexuality and reproduction, five items on coping and stress, four items on value and religion, three items on family. and three items on facilities and environment. 3. Instrument for measurement of self-care The instrument for self-care measurement was classified with scales according to the attributes of the disease. Each scale measured understanding level and practice level by a Yes or No scale. Understanding level was measured by interview but practice level was measured by both observation and interview. Items for self-care measurement included 14 for patients with a CVA, five for women who had a cis, ten for patients with lung cancer, 12 for patients with COPD, five for patients with a simple nephrectomy, and 11 for patients with LC. 4. Record for follow-up management This included (1) OPD visit sheet, (2) ER visit form, (3) complications problem form, (4) readmission sheet. and (5) visit note for others medical centers which included visi
