매입임대주택 내 옥상텃밭의 실태분석을 통한 지속가능한 운영방안
박희은,이연숙,김인호 한국생태환경건축학회 2019 한국생태환경건축학회 논문집 Vol.19 No.4
Purpose: Recently, the number of vulnerable people due to an aging society is in dire need of housing welfare for them. Thus, the local government created a rooftop gardening in the purchased rental housing to provide housing support as a community space and is pushing for the promotion of the self-help and revitalization of the community among the vulnerable. In order to ensure that the rooftop garden is sustainable rather than being isolated, however, the field of rooftop garden is still in a inferior stage and there is a possibility that the roof garden will be destroyed when the problem is not reconciled. Thus, the purpose of this study is to suggest sustainable operation of rooftop gardens in purchased rental houses. Method: The scope of this study was to select a total of seven housing sites with support for gardening activities over the three years from 2015 to 2018 and the results derived through qualitative research methods were analyzed as hardware, contentware and humanware. Result: On the hardware side, necessary facilities for rooftop gardening should be established to take into account of user characteristics. On the contentware side, customizable gardening program should be provided. On the humanware side, residential community formation should be provided to enable active participation and cooperation by participants.

고정화된 aspergillus phoenicis를 이용한 progesterone 전환
박희은,김말남 한국미생물학회 1989 미생물학회지 Vol.27 No.1
Progestrone bioconversion by immobilized Aspergillus phoenicis was studied. Progesterone was converted into 11$\alpha$-hydroxyprogesterone and 3-minor byproducts. Whole cells of A. phoenicis were immobillized by enreappment with calcium-alginate, K-carrageenan, or polyacrylamide. Of these materials tested, cell immobilized in $Ca^{2+}$ -alginate gels showed the highest activity for 11$\alpha$-hydroxylation of progesterone. In the case of mycelia immobilized in $Ca^{2+}$-alginate, futher progressing hydroxylation of 11$\alpha$-hydroxyprogesterone was greatly reduced. Spores of A. phoenicis which were immobillized with $Ca^{2+}$-alginate and germinatedin situ for 25 hours showed higher 11$\alpha$-hydroxylase activity than those of entrapped whole mycelia and maintained initial enzyme activity for all 8 times of repeated use. After 16 times of reuse, the activity was declined 30% or more. When culture media and $Zn^{2+}$ were introduced into the reaction media, the activity of the immobilized mycelia which had been lowered due to many times of reuse was effectively reactivated.

Background and Objectives The presence of ectopic tooth in the sinonasal cavity is an unusual phenomenon and the underlying etiology remains unclear. Because of its rarity, clinical observation studies about sinonasal ectopic tooth are very rare. The aim of this study was to analyze the clinical characteristics of ectopic tooth occurring in the sinonasal cavity. Subjects and Method Medical records and radiologic studies of 11 patients, who were treated between January 2006 and June 2012 for ectopic nasal teeth were reviewed retrospectively, with regard to sex, age, location, symptoms and treatment methods. Results Among 11 patients, 8 patients were male and 3 patients were female. The average age was 24.2 years. Among 7 patients who had symptoms, nasal obstruction was the most common followed by rhinorrhea, postnasal drip, facial swelling or pain, headache. The nasal cavity was the most frequently affected site. Among 14 ectopic teeth from eleven patients, 7 were removed by intrasnasal endoscopy and 2 by external premaxillary approach. Five teeth which were unerupted within the hard palate or maxillary sinus were offered conservative treatment with periodic follow-up. Conclusion Removal of ectopic nasal tooth is generally advocated to alleviate the symptoms and prevent complications; if conservative treatment is decided, periodic monitoring of the patient is recommended. We suggest that treatment be carefully planned based on the symptoms of patients, location of the ectopic tooth, and whether the tooth is erupted or not.

The aim of the present study was to validate Swedish Zimbardo time perspective inventory (S-ZTPI). To validate this, factor analysis was conducted with the data of 411 participants. The present study identified 5 factors on Korean version of ZTPI. As a result of reliability analysis after confirming 45 items of the inventory, every subscale showed moderate level of internal consistency. To identify the character of each time perspective, correlation analysis between time perspectives, self-esteem, state anxiety, and depression was conducted. As a result, past-negative and present-fatalistic time perspective was negatively correlated with self-esteem and positively correlated with state anxiety and depression. Present-hedonic time perspective had positive correlation with state anxiety and depression. The present study identified that 6 factor of S-ZTPI was not fit in Korea and validity of 5 factor Korean version of ZTPI, and also enhanced comprehension about time perspective of Koreans by investigating the relationship between time perspective and psychological factors. 본 연구는 개인의 시간관을 측정하는 짐바르도 시간관 설문지(ZTPI)에 미래-부정 문항을 추가해 미래지향적 시간관을 미래-긍정과 미래-부정적 시간관으로 구분한 Swedish ZTPI(S-ZTPI)를 타당화하였다. 이를 위해 10대부터 70대까지 총 411명을 대상으로 요인분석을 실시하여 한국형 ZTPI의 5요인 구조를 확인하였는데, 요인부하량이 낮은 19문항을 제거하고 최종 45문항을 확정하여 신뢰도 분석결과, 모든 하위요인에서 적정한 수준의 문항내적합치도(.70~.84)를 보였다. 각 시간관의 특성을 분석하기 위해 자아존중감, 상태불안, 우울과의 상관관계를 분석한 결과, 미래 지향적 시간관은 자아존중감과 정적 상관을 보였으나 상태불안과 부적 상관을 보였다. 과거-부정, 현재-숙명 시간관은 자아존중감과 부적 상관을 보였으나 상태 불안, 우울과 정적 상관을 보였고, 현재-쾌락 시간관은 상태 불안, 우울과 정적 상관을 보였다. 본 연구 결과를 통해 한국에서는 6요인의 S-ZTPI가 적합하지 않았으며, 5요인의 한국형 ZTPI의 타당성을 확인할 수 있었다. 또한 자아존중감, 우울, 불안 등의 심리학적 요인들과 시간관의 관계를 탐색함으로써 한국인의 시간관에 대한 이해도를 높였다.
