In this study, we prepared ACFs with a high specific surface area from various precursors (rayon, pitch, and oxidized polyacrylonitrile-based fibers) by a steam-activation technique and investigated the effects of the micropore and mesopore fraction on 2-CEES adsorption behaviors. The activation time was precisely controlled so that the activation yield was in the range of 35–40% to ensure the mechanical properties of the ACFs. The N2 adsorption isotherm characteristics at 77K were confirmed by Brunauer–Emmett–Teller, Barrett–Joyner–Halenda and non-local density functional theory equations. The adsorption capacities of the ACF were measured by breakthrough experiments in the gas phase (750 μg/mL of 2-CEES in N2 flow). The removal efficiency of the ACFs was evaluated and compared with that of AC. From the results, specific surface areas and total pore volume of the ACF were determined to be 1380–1670 m2/g and 0.61–0.82 cm3/g, respectively. It was also observed that various pore characteristics of ACF were found to be dependent on crystallite structure of each precursor. The break through time (C/C0 = 0.10) was in the order of Oxi-Pan-H-9-2 < Saratoga AC < Rayon-H-9-3 < Pitch-H-9-4. This indicates that 2-CEES adsorption capacity could be a function not only of specific surface area or total pore volume, but also of sub-mesopore volume fraction in the range of 1.5–2.5 nm of adsorbents.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

음반자료에 기록된 삼현육각 음악에 대한 연구 -악곡 및 연주자를 중심으로-

강혜진(Kang, Hye-jin) 한국음악문화학회 2019 한국음악문화연구 Vol.13 No.-

본 연구는 1996년 임혜정이 조사한 삼현육각 음반 목록과 _한국음반학_, _국악연감_의 음반 목록 중 삼현육각 관련 악곡을 대상으로 진행되었다. 유성기․LP․CD 음반에 실린 삼현육각 음반 목록을 정리하고 수록된 악곡과 연주자들을 중심으로 삼현육각 음악을 연구하였다. Columbia 유성기 음반에는 서울 경기 지역의 삼현육각 악곡과 평양과 봉산의 탈춤에 사용된 삼현육각 악곡이 수록되어 있었고, Victor 유성기 음반에는 무용 반주 음악으로 사용된 삼현육각 악곡이 주로 수록되어 있었다. 한편, 1906년 녹음되어 1907년 발매된 Victor 음반에 실린 최초의 삼현 육각 악곡이 2015년에 발굴되었는데 이는 삼현육각 악곡이 실린 최초의 음반으로 음악사적으로 큰 가치를 가진다. LP 음반에는 모두 경기 지역에서 연주했던 삼현육각이 무용곡으로 사용된 것만 녹음되어 있음을 확인할 수 있었다. 1990년대 후반부터는 개별 연주자를 중심으로 주로 무속 음악에 사용된 삼현육각 CD 음반이 다수 발매되었다. 2000년대에 들어서는 국립문화재연구소와 국립국악원을 중심으로 전통음악의 보존과 전승을 위한 시리즈 형식의 음반 중에 삼현육각 음반이 활발하게 제작되었다. 2010년대에 와서는 CD 음반을 따로 발매하기 보다는 디지털 음원만 발표하는 경우가 많아지면서 삼현육각 CD 음반의 발매수도 현저히 줄어들었다. 삼현육각 음반에 대한 연구는 삼현육각 음악의 변천 과정과 지역별 삼현육각 음악의 특성 파악, 궁중과 민간․무속음악인들의 음악 교류 양상 파악 등을 위해 필요하다. 앞으로 삼현육각 음반에 수록된 악곡과 연주자들에 관한 더 심층적인 연구가 이루어지길 바란다. This study was conducted on music related to Samhyun-yukgak record list among the 1996 Im, Hye-jung"s study and the _Korean discography_ and _Gugak-yearbook_. It compiled a list of Samhyun-yukgak on the phonograph records, LP and CD records and studied Samhyun-yukgak music based on the music pieces and musicians. Columbia phonograph records contained Samhyun-yukgak music pieces of the Seoul, Gyeonggi and Samhyun-yukgak music pieces used for mask dance of the Pyongyang, Bongsan. Victor phonograph records contained Samhyun-yukgak music pieces used for dance accompaniment. On the one hand, the first Samhyun-yukgak music peices in Victor record, recorded in 1906 and released in 1907, was unearthed in 2015. These are the first Samhyun-yukgak music records and great value in music. The LP records showed that the Samhyun-yukgak, all played in the Gyeonggi area, were recorded only used dance accompaniment. Since the late 1990s, individual performers have been released a number of Samhyun-yukgak CD records, mostly used in shaman music. In the 2000s, Samhyun-yukgak records were produced actively as the series-type records for the preservation and transfer of traditional music by the "National Research Institute of Cultural Heritage" and "National Gugak Center". Come in 2010s, the number of CD releases feature Samhyun-yukgak is significantly reduced with increasing Digital Sound. A Study on the Samhyun-yukgak records are necessary for understanding the transition process of Samhyun-yukgak, the regional characteristic of Samhyun-yukgak, and the music exchange aspect among court, folk and shaman musicians. I hope that in the future, more in-depth research will be done on the music pieces and the musicians in Samhyun-yukgak records.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

Objective:We studied the effect of Hyu-Sig-Gong-Gan and Hye-Ah-Rim on several evaluations and compared the two programs. We then investigated factors associated with the difference between pre- and post-ratings. Methods:Thirty-six patients were randomized to Hyu-Sig-Gong-Gan (n=23) or Hye-Ah-Rim (n=13). We tested for the effect of each program on several evaluations and compared the two programs through Zarit Burden Interview (ZBI), Center for Epidemiologic Studies-Depression Scale, Dementia Attitude Scale (DAS)-intelligence, DAS-comfort and DAS-total. We then investigated whether the difference between pre- and post-rating depends on other factors. Results:We observed significant positive effect of Hyu-Sig-Gong-Gan on DAS-comfort (t=1.843, p=0.039) and significant positive effect of Hye-Ah-Rim on ZBI (t=-2.327, p=0.019), DAS-comfort (t=2.241, p=0.022), and EuroQol-5 Dimensions-Visual Analogue Scale (t=2.537, p=0.013). For comparing the two programs, we found a lack of evidence for the difference in any of the five commonly observed evaluations. In the secondary analysis, we observed a strong trend that the two programs were particularly effective for caregivers with negative pre-ratings. Conclusion:The two programs showed positive effects on the various evaluations, but some evaluations could not reach statistical significance. The programs appear to be particularly helpful for those who are in need before the program participation.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.
