  • 2004년 1월부터 12월까지 부산 주변해역에서 채집된 참돔의 식성을 조사하였다. 참돔의 체장분포는 8.5~44.6 cm SL의 범위였다. 참돔의 주요 먹이생물은 집게류 (Anomura), 단각류 (Amphipoda), 게류 (Brachyura), 새우류 (Caridea), 갯지렁이류 (Polychaeta), 극피동물 (Echinodermata), 어류(Pisces) 등 매우 다양했다. 그 외, 복족류(Gastropoda), 이매패류(Bivalvia), 갯가재류(Stomatopoda), 두족류(Cephalopoda) 자포동물(Cnidaria), 등각류(Isopoda) 등도 소량 섭이하였다. 참돔은 성장함에 따라 먹이생물 조성에 있어 변화를 보였는데, 체장 8~15 cm SL에서 새우류의 점유율이 높았으며, 15~25 cm SL에서는 집게류와 갯지렁이류의 점유율이 높았다. 그리고 25 cm SL 이상에서는 극피동물류와 어류의 점유율이 높게 나타났다.

  • Purpose: This study was conducted to investigate academic self-efficacy, metacognition and major satisfaction which influence learning flow in nursing students. Method: The subjects of this study were 239 nursing students in D college. Structured questionnaire was self-administered from May 3 to 30, 2021. The date was analyzed by t-test, ANOVA, Pearson'correlation coefficients, stepwise and multiple regression using SPSS/WIN 22.0. program. Results: In academic self-efficacy, there were significant differences in age. In metacognition, there were significant differences in age, school record. There was a statistically positive correlation between learning flow and academic self-efficacy(r=.211, p=.001), metacognition(r=.357, p<.001), major satisfaction(r=.281, p<.001). The factors influencing learning flow were metacognition(t=.682, p<.001), major satisfaction(t=2.147, p=.023)Multiple regression analysis description is 61.2%. Conclusion: To improve the learning outcomes for nursing students, it is necessary to develop teaching program and curriculum for increasing, metacognition and major satisfaction.

  • The aim of this study was to assess the cytotoxic effects of various concentrations of miltefosine on Leishmania major (MRHO/IR/75/ER) and L. tropica (MHOM/IR/02/Mash10) promastigotes and to observe the programmed cell death features. The colorimetric MTT assay was used to find L. major and L. tropica viability and the obtained results were expressed as 50% inhibitory concentration (IC50). Also, 50% effective doses (ED50) for L. major and L. tropica amastigotes were also determined, Annexin-V FLUOS staining was performed to study the cell death properties of miltefosine using FAGS analysis. Qualitative analysis of the total genomic DNA fragmentation was performed by agarose gel electrophoresis. Furthermore, to observe changes in cell morphology, promastigotes were examined using light microscopy. In both strains of L. major and L. tropica, miltefosine induced dose-dependent death with features of apoptosis, including cell shrinkage, DNA laddering, and externalization of phosphatidylserine. The IC50 was achieved at 22 ${\mu}M$ and 11 ${\mu}M$ for L. major and L. tropica after 48 hr of incubation, respectively. ED50 of L. major and L. tropica amastigotes were 5.7 ${\mu}M$ and 4.2 ${\mu}M$, respectively. Our results indicate that miltefosine induces apoptosis of the causative agent of cutaneous leishmaniasis in a dose-dependent manner. Interestingly, L. major did not display any apoptotic changes when it was exposed to miltefosine in concentrations sufficient to kill L. tropica.

  • Purpose : The purpose of this study was to identify the self-efficacy, major satisfaction, and degree of adjustment to college life of nursing students and the relationships among the foregoing. Methods : This study was conducted with 319 nursing students in B city from May to June 2019. The collected data were analyzed with frequency, percentage, mean and standard deviation, t-test, ANOVA, Scheffe's test, and Pearson Correlation Coefficient using the SPSS /WIN 22.0 program. Results : The self-efficacy score of nursing college students was shown to be 2.95±0.32 points, major satisfaction score was shown to be 3.83±0.55 points, and college adjustment score was shown to be 3.52±0.55 points. The degrees of adjustment to college life were significantly different according to general characteristics of nursing students as follows; grade (F=6.614, p=.000), health condition (F=13.384, p=.000), club activities (t=4.557, p=.000), happiness index (F=32.094, p=.000), part-time job (t=2.781, p=.006), and motive of major selection (F=7.300, p=.000). The adjustment to college life of nursing students showed a weak negative correlation with self-efficacy (r=-.196, p<.001) and a strong positive correlation with major satisfaction (r=.782, p<.001). Major satisfaction and self-efficacy showed a weak negative correlation (r=-.185, p<.001). Conclusion : Through the results of this study, it can be seen that repetitive studies are necessary in relation to the self-efficacy, major satisfaction, and college adjustment of nursing students, and that interest in effort for the development of programs that can improve nursing students' major satisfaction and college adjustment are necessary.

  • 본 연구는 간호대학생의 전문적 자아개념, 학업적 자기효능감 및 전공만족도의 정도를 파악하고 이들 간의 관계를 확인하는 서술적 조사연구이다. 연구대상은 J도의 4년제 간호대학생 137명을 대상으로 하였으며 자료수집은 2017년 10월 19일부터 23일까지 이루어졌으며, 수집된 자료는 기술통계, 상관분석 및 다중회귀분석을 사용하여 분석하였다. 간호대학생의 전문직 자아개념은 학업적 자기효능감(r=.598, p<.001) 및 전공만족도(r=.598, p<.001)와 유의한 상관관계가 있으며, 학업적 자기효능감은 전공만족도(r=.470, p<.001)와 유의한 상관관계를 나타내었다. 간호대학생의 전공만족도에 영향을 미치는 요인은 전문직 자아개념(${\beta}=.479$, p<.001)으로 36.0%의 설명력을 보였다. 본 연구 결과 전문직 자아개념이 전공만족도에 긍정적인 영향요인으로 확인되었으므로 간호학생의 전공만족도를 높이기 위해 전문직 자아개념을 향상시킬 수 있는 교육내용을 잘 구성하는 교과목과 프로그램 개발이 필요할 것으로 사료된다.

Western astrology is transmitted from China and developed, it influenced on the study of the Four Pillars(四柱學). Comparing assemble, gathering, punishment, destruction, collision, impair of Di-zhi(地支) in the study of Four Pillars with Xing-gong theory(星宮論) in the western astrology, can get the result that the Pillars study has close connection with astronomy and astrology. When we compared Jung's psychological types with astrology, the five elements(五行) and the four major factors, can be summarized like this.

  • This study focuses on a comparative study of 1960s'retro look mode in terms of the past and present in order to find out in detail how it in the past is readjusted after it was appeared in the present. For such a study, in the first place the contents of the dress and its ornament of a retro-look fashion was refined through some literature, and then, some works of the dress and its ornament of a retro-look fashion was refinded through some literature, and then, some works of eh dress and its ornament revived in 1960's mode were analysed, based on some fashion magazines at home and abroad like Bazaar, Fashion etc News in 1990s. After 1960s'retro-look mode which reappeared in 1990s was researched in terms of silhouette, detail, texture, color, and pattern, differences between those tow periods of 1960s and 1990s and their causes are summarized as follows: 1. In the aspect of silhouette, it appears that the silhouette in 1960s is that of somewhat stiff, charming image in which Body is excluded and the silhouette in 1990s is that of an soft, feminie image in which Body is emphasized. It was understood that the cause of such a delicate difference comes from the influences of the change in aesthetic senses or awareness, naturalism and neo-feminism. 2. In the aspect of detail, it appears that the detail in 1990s is of an attempt to express in diverse images, compared to that in 1960s, and new images are created new image in 1990s by means of presenting entirely ill-matched images. The major cause of that is because of Antistandard fashion. 3. In the aspect of textures, it appears that a great feature is that the texture in 1990s is of that introduced, being changed in natural and high-class looks, compared to that of 1960s. It was reviewed that the major cause of this is because of a result from the influence of naturalism and the technical growth in various fields which has brought the development of dress material. 4. In the aspect of color, it appears that the color in 1990s is of an image of primary color which is far more sensual and feminie than that of 1960s. It was studied that the major cause of ti comes from the influence of neo-feminism, etc. 5. In the aspect of pattern, it appears that the pattern in 1990s is of that of symbolism, transposition, and the ecletic feature of various modes which appear more deeply than that of 1960s. It was studied that the major cause of such changes is because of a trend of postmodernism which has brought the change of the spiritual structure different from that in the age of modernism. In conclusion, it was understood that the retro-look fashion is of an expression technic of dress and its ornament in that o dress in the pst is simply imitate, but new reconstitution is done by using the elements in the past. at the same time, ti was clarified that even though the elements in the past are revived as they were, dress and its ornament is governed by the social and cultural environments of he day, and with this proof it can be said that the fashion in each age is of a reflection of social phenomena of that age.
