Building is a major energy consumer, and now many efforts are made to save energy in the design and using equipments. The most noticeable achievement in those efforts is a building energy performance assessment program. But most programs are not satisfying enough to provide exact meteorological data, and data source and calculation, and data collection period are not clearly defined. That is common in most of domestic programs. This study collects typical meteorological data in 16 items and analyzes them with Visual DOE 4.0 to compare with existing data. The comparison found that revised data shows a 11% increase on average during cooling period from June to September, and a 13% decrease on average during heating period from December to February, in terms of building heating and cooling load in a monthly basis.

Purpose: This study was to explore and describe the reported experiences of elderly spouses who care their bedridden spouse in the home. Methods: The participants of this study were 14 male and female elderly spouses who live in B metropolitan city and have provided care for more than six months. Data were collected from July 3 to November 6, 2014. Data analysis was done simultaneously with data collection, using the analytical methods of Strauss and Corbin for Grounded theory. Results: The core category was identified as 'going together bearing a heavy burden of care in old age.' In this study, the caring process of elderly spouses can be explained in terms of three stages such as 'a period of trial and error,' 'a period of mastering a role,' and 'a period of role transcendence'. Conclusion: The results of this study can provide an intervention framework to reduce the heavy burden of caring for an elderly spouse.

본 연구는 우산고로쇠나무 조림지에서 수액 출수 특성을 구명하고자 수행하였다. 그 결과, 우산고로쇠나무 수액 출수량은 일 평균기온 $3.4^{\circ}C$ 이상 오를 시 출수량이 급격히 감소하였으며, 이를 고려해볼 때, 2월 하순 이전에 수액채취를 하는 것이 효율적일 것으로 판단되었다. 하루 중 수액출수는 약 9시경부터 출수를 시작하여 11시경에 최대량이 출수되었고 16시경에 출수가 종료되었다. 수액 당도는 시간이 흐름에 따라 감소하는 경향이 나타났으며, Na를 제외한 다른 무기성분들은 시기별 차이는 없었다.

This study was conducted to investigate the effects of epinephrine and norepinephrine on basal gastric acid secretion and plasma gastrin and secretin concentration in the conscious rat. One hundred and eighty-four albino rats with gastric cannula were used after 18 hours or more of fast, with water ad libitum. In a restraint cage for collection of gastric juice, physiological saline (0.9% NaCl) was continuously infused into the jugular vein through a catheter for one hour at a rate of 1 ml/hr (control period). Immediately after the control period, epinephrine (1, 2, 4, 8 and $16{\mu}g/ml/hr)$, norepinephrine (1, 2, 4, 8 and $16{\mu}g/ml/hr)$ or physiological saline (1 ml/hr) was infused for another one hour. Gastric juice was collected at one hour interval for two hours infusion period. Adrenergic antagonists, phentolamine and propranolol were injected into the jugular vein 5 min prior to the infusion of epinephrine or norepinephrine at a dose of 0.2 mg/0.1 ml. Blood was sampled from the jugular vein for the radioimmunoassay of plasma gastrin and secretin after the collection of gastric juice. The results were as follows: 1) Both epinephrine and norephinephrine significantly increased gastric acid output in a dosedependent manner. 2) The effects of epinephrine and norepinephrine on the gastric acid secretion were antagonized by the pretreatment with phentolamine and propranolol. 3) Plasma gastrin and secretin concentrations were not significantly affected by the intravenous infusion of epinephrine and norepinephrine. It can be inferred from the above results that epinephrine and norepinephrine facilitate gastric acid secretion in conscious rats and the mechanism of which is attributed to ${\alpha}\;and\;{\beta}$ adrenergic receptors rather than gastrin and secretin.

This study examines changes in consumer perceptions of fashion shows, which are critical elements in the apparel industry and a means to represent a brand's image and originality. For this purpose, big data in clothing marketing, text mining, semantic network analysis techniques were applied. This study aims to verify the effectiveness and significance of fashion shows in an effort to give directions for their future utilization. The study was conducted in two major stages. First, data collection with the key word, "fashion shows," was conducted across websites, including Naver and Daum between 2015 and 2018. The data collection period was divided into the first- and second-half periods. Next, Textom 3.0 was utilized for data refinement, text mining, and word clouding. The Ucinet 6.0 and NetDraw, were used for semantic network analysis, degree centrality, CONCOR analysis and also visualization. The level of interest in "models" was found to be the highest among the perception factors related to fashion shows in both periods. In the first-half period, the consumer interests focused on detailed visual stimulants such as model and clothing while in the second-half period, perceptions changed as the value of designers and brands were increasingly recognized over time. The findings of this study can be utilized as a tool to evaluate fashion shows, the apparel industry sectors, and the marketing methods. Additionally, it can also be used as a theoretical framework for big data analysis and as a basis of strategies and research in industrial developments.

Purpose: The purpose of this study was to explore the psychosocial adjustment process in adolescents with epilepsy in the context of Korean society and culture. Method: A grounded theory method was used for data collection and analysis. Participants for this study were 9 adolescents who regularly visited an epilepsy clinic in a university hospital. The data was collected through in-depth interviews during the period from November, 2002 to June, 2003. Data collection and analysis were performed simultaneously. Result: Twenty-three categories emerged including 'suffering', 'psychological stigma', and 'social isolation from one's peers'. Categories were divided into paradigms which consisted of conditions, actions/ interactions, and consequences. 'Reconstructing life' was the core category in this study. The theoretical scheme was described by organizing categories around the core category. Conclusion: This study provides a framework for the development of individualized nursing interventions to care for adolescents with epilepsy.

The study is a phenomenological analysis of the video simulation clinical practice experience recently conducted on nursing students due to the outbreak of corona 19 worldwide. A total of eight students participated in the vSim class who understood the purpose of the study and wanted to participate voluntarily. The data collection conducted a total of three interviews until no new data was available, and the collection period was from June 22, 2020 to July 10, 2020. The collected data were analyzed with the Giorgi's Phenomenological Analysis Method. As a result of the study, three components and 13 semantic units were derived. vSim was difficult for students, but it was an interesting experience that made them feel like nurses, and it was an experience in which they were immersed in learning rather than face-to-face classes, and their skills improved.
