  • Multi-wavelength variability is a staple of active galactic nuclei (AGN). Optical variability probes the nature of the central engine of AGN at smaller linear scales than conventional imaging and spectroscopic techniques. Previous studies have shown that optical variability is more prevalent at longer timescales and at shorter wavelengths. Intra-night variability can be explained through the damped random walk model but small samples and inhomogeneous data have made constraining this model hard. To understand the properties and physical mechanism of intra-night optical variability, we are performing the KMTNet Active Nuclei Variability Survey (KANVaS). Using KMTNet, we aim to study the intra-night variability of ~1000 AGN at a magnitude depth of ~19mag in R band over a total area of ${\sim}24deg^2$ on the sky. Test data in the COSMOS, XMM-LSS, and S82-2 fields was obtained over 4, 6, and 8 nights respectively during 2015, in B, V, R, and I bands. Each night was composed of 5-13 epoch with ~30 min cadence and 80-120 sec exposure times. As a pilot study, we analyzed data in the COSMOS field where we reach a magnitude depth of ~19.5 in R band (at S/N~100) with seeing varying between 1.5-2.0 arcsec. We used the Chandra-COSMOS catalog to identify 166 AGNs among 549 AGNs at B<23. We performed differential photometry between the selected AGN and nearby stars, achieving photometric uncertainty ~0.01mag. We employ various standard time-series analysis tools to identify variable AGN, including the chi-square test. Preliminarily results indicate that intra-night variability is found for ~17%, 17%, 8% and 7% of all X-ray selected AGN in the B, V, R, and I band, respectively. The majority of the identified variable AGN are classified as Type 1 AGN, with only a handful of Type 2 AGN showing evidence for variability. The work done so far confirms there are more variable AGN at shorter wavelengths and that intra-night variability most likely originates in the accretion disk of these objects. We will briefly discuss the quality of the data, challenges we encountered, solutions we employed for this work, and our updated future plans.

  • 무당벌레 (Harmonia axyridis)는 특이한 초시색상과 분양을 가지고 있으며, 종내에 변이가 심하다. 현재까지 무당벌레 개체군 안에서 이러한 변이의 주요원인은 내적인 요인과 물리적 환경적인 요인들이 작용하고 있다고 알려져 있다. 사실 이러한 변이들이 유전적 또는 환경적으로 일어나는지에 대한 확실한 증거는 찾을 수 없다. 그렇지만, 많은 종류의 색상 패턴들 가운데 유전적인 면이 담겨져 있는 것을 특정한 색상패턴의 개별적인 교배를 통하여 일부 확인하였다. 일부의 교배에서는 초시색상과 문양의 유전적 특정을 일부를 확인할 수 있었고, 변이의 유전적 분석에 도움을 줄 수 있는 결과를 얻은 것에 의미를 부여하고자 한다.

  • Tobacco use is the most readily preventable cause of premature death; it is a worldwide problem, with a significant impact on heath and well-being. In order to design an effective tobacco education program, it is important to understand smoking patterns and the underlying factors associated with smoking in different generations such as adults or young people. Despite a general decline in the prevalence of regular smoking among adults, recent surveys commissioned by the Ministry Heath & Welfare for the Republic of Korea have shown no evidence of any decline in smoking rates among young women and adolescents. The Republic of Korea has the highest adult male smoking percentage (65.1%) in the world and smoking in adolescents is still an increasing trend. Smoking in adolescents and young women is especially more dangerous, thus health education of anti-smoking directed at these groups is an important area that will benefit from using internet content that they can easily access. The purpose of this study is the evaluation of visual perception and effectiveness analysis in smoking cessation websites in promoting smoking cessation in adolescents and young women through Internet content. As a result of this project, at first we evaluated the Internet content of cyber smoking cessation programs by the evaluation criteria of web design interface. The Internet site of http://nosmokeguide.or.kr received the most superior evaluation in the domestic Internet content for smoking cessation and the Internet site of the National Center for Tobacco-Free Kids received the most superior evaluation in the foreign Internet content for smoking cessation. This evaluation was surveyed by an expert in Internet content and user. Secondly, we developed the Internet content for cyber smoking cessation program, namely, "Dr. Smoking" that contained several menus and a database regarding anti-smoking designed in accordance with the results of this evaluation. The domain address of Dr. Smoking is http://www.dmosmoking.com and our webpage has assorted kinds of news, information, self-diagnosis, prescription, consulting, a no-smoking mall etc. In conclusion, this project is designed to develop Internet content for the most effective smoking cessation program and to contribute to eliminating smoking from our society. We also will try to develop and upgrade this web-site in order to help a smoker who want to quit smoking and diminish the physical and socioeconomic harm from smoking.m smoking.

  • 본 연구는 질적 연구를 통하여 의료급여환자들의 의료이용 경험을 이해함으로써 의료급여환자와 건강보험환자 간 의료이용량의 통계적 차이현상의 원인과 과정을 파악하기 위해 수행되었다. 주요 분석결과는 다음과 같다. 첫째, 의료급여환자의 과잉의료는 대체로 존재하지 않으며, 복합적 질병을 가지고 있어서 발생하는 것이다. 그러나 물리치료와 한방 침에 있어서 일부 과잉이용이 발생하고 있는 것으로 판단된다. 둘째, 의료급여환자들은 의료비를 마련하기 위하여 생계급여에서 일부를 활용하거나 주변 가족이나 이웃의 도움을 받고 있었다. 그러나 과도한 의료비 부담으로 비급여 의료서비스와 대형병원 의료이용은 실제 의료필요만큼 이용하지 못하고 있었다. 또한 일부 환자는 아파도 우선 참고 견디고 있었다. 한편, 일부 의료기관에서는 의료급여환자에 대한 차별적 진료행위를 여전히 하고 있었다. 셋째, 공무원과 의료기관 모두는 의료급여환자에게 의료비 지원정책에 대한 미흡한 정보 제공 등 충분한 도움을 주지 못하고 있었다. 넷째, 정부가 수행하고 있는 의료급여정책인 선택병의원제도, 의료급여사례관리제도, 진료연장승인제도 모두는 불필요한 의료이용을 감소시키는데 기여하고 있는 것으로 판단된다. 그러나 의료급여환자들에게 필요한 의료이용을 제한하는 문제를 초래할 수 있어 이에 대한 대책마련이 요구되었다. 이상의 연구결과를 살펴보면 건강보험환자와 의료급여환자의 의료이용량의 차이를 통계적으로 검증한 선행연구와는 달리 의료급여환자들은 의도적인 과잉이용을 하지 않고 있으며, 오히려 필요한 의료서비스 이용에 제한을 받는다고 생각하고 있었으므로, 이에 대한 대책마련이 요구된다.

  • Purpose: Congenital absence of the vagina is a rare case. It occurs as a result of Mullerian duct aplasia or complete androgen insensitivity syndrome. The reconstructive modality includes skin graft, use of intestine and various methods of flap. We report a patient who underwent vulvoperineal fasciocutaneous flap to reconstruct congenital absence of the vagina, while the external genitalia and ovaries are normal. Methods: A 26-year-old woman presented with vaginal agenesis. Under general anesthesia, a U-shaped incision was made between the urethral meatus and the anus. The new vaginal pocket was created up to the level of the peritoneal reflection between the urinary structures and the rectum. Next, the vulvoperineal fasciocutaneous flaps were designed in a rectangular fashion. Flap elevation was begun at the lateral margin which the adductor longus fascia was incised and elevated, and the superficial perineal neurovascular pedicle was invested by the fascial layer. The medial border was then elevated. A subcutaneous tunnel was created beneath the inferior of the labia to rotate the flaps. The left vulvoperineal flap was rotated counterclockwise and the right was rotated clockwise. The neovaginal pouch was formed by approximating the medial and lateral borders. The tubed neovagina was then transposed into the cavity. Results: In 3 weeks, the vaginal canal remained supple After 6 weeks, the physical examination showed normalappearing labia majora and perineum with an adequate vaginal depth. A year after the operation, the patient had a 7 cm vagina of sufficient width with no evidence of contractures nor fibrous scar formation. The patient was sexually active without difficulty. Conclusion: Although many methods were described for reconstruction of vaginal absence, there is not a method yet to be approved as a perfect solution. We used the vulvoperineal fasciocutaneous flap to reconstruct a neovagina. This method had a following merits: a single-stage procedure, excellent flap reliability, the potential for normal function, minimal donor site morbidity and no need for subsequent dilatation, stents, or obturators. We thought that this operation has a good anatomic and functional results for reconstruction of the vagina.

  • Objectives: The purpose of this study was to research learning based on brain science and the learning methodology of Korean Medicine according to disparity of age. Through this, the study aimed to provide a guideline to related Korean Medicine treatments as well as the common nurturing/educational institutions. Methods: All journals and dissertations on brain science based learning methods studied in Korea to date that could be found in the National Assembly Library and the RISS were implemented in the analysis. The terminology used for search was as follows: 1st search, 'Brain'; 2nd search, 'Learning', 'Education'; 3rd search, 'Baby, 'Infant', 'Child'. For the learning methodology of Korean Medicine according to disparity of age, the related contents were extracted from Donguibogam and Liuyi, Sasang constitutional medicine. Results: A total of 30 studies, were collected as data. In the baby stage, the development and myelination of brain neurons are accelerated by experience and learning, highly influenced by social, cognitive and emotional movement. In infancy, the frontal lobe actively develops, so education for development of the prefrontal cortex is suggested. The brain of the infant at this stage can be developed by arts and physical education. In the child stage, the parietal and temporal lobe develop actively. Thus, programs to stimulate brain activity including brain respiration would be helpful in enhancing learning ability, concentration, etc. As evidence for learning and nurturing methodology according to disparity of age from Korean Medicine prospective, the following are listed: Location and time for sexual intercourse before pregnancy, stabilization during pregnancy, baby nurturing methods for nurturing from Donguibogam. Also Liuyi and Sasanag constitutional medicine can be the learning methodology according to disparity of age. And there are acupuncture points on each head section according to age in Donguibogam. Conclusions: Studies on 'brain-science based learning' are continuously being conducted. Based on these studies, diverse new brain-science based learning will be developed in the future. There is also a need to develop the learning methodology of Korean Medicine according to disparity of age in a more systematic and diverse way.

  • This study was conducted for the purpose of identifying the trends of nursing research and to suggest the direction of future research in the graduate levels of the study. The data was collected from 469 abstracts of master's and doctoral rapers from three graduate schools, one in Nursing, another in Education, and the other in Public Health Graduate College. The results of the study are as follows: The number of research was increased from 102 to 286 between the 1970 s and 1980's. The most frequently employed research design was descriptive studies in the master's level, but there was some balance between descriptive and experimental studies along with some qualitative approaches in the doctoral thesis. Patients were the most often studied sample group reaching 42% of the cases, though it Was noted that there was steady shift: toward the non-ratient population. With this shifting of the study sample, the places of the study also have showed some changes moving toward community. The most widely studied area was in clinical practice. Chronic illness, preventive, and health promoting areas of studies also increased in numbers. However, most of them were at the descriptive level of phenomena and only a few were concerned with cost/effective measures of nursing intervention. The number of variables studied repeatedly more than five times was 43. They were not only physical but also psychosocial aspects which imply the efforts to incorporate the whole person in nursing discipline. However, most researches with repeated studies showed little relation to previous studies, and thus little accumulation in knowledge. There was also little evidence of linkage to nursing theory in most studies of master's level. For the doctoral rapers, 17 out of 51 rapers showed specific theories related to the researches. Based on the above findings, the following suggestions were made. Various research design should be employed including case studies, historical studies, as well as qualitative approaches. There should be more effort to establish linkage between theory and research. The areas needing more attention are Korean Nursing History, Ethics in our Culture, Cost/Effective Measures of Nursing Intervention, Concept and Thory Development, and the Strategies for the Implication of the Research Results in clinical practice.

  • 이 글은 <하진양문록>의 남성주동인물 진세백의 행위와 심리를 주로 여성주동인물인 하옥주와의 관계를 중심으로 살펴 진세백의 작품 내적 성격을 정립하고 그 소설사적 위상을 점검하는 것을 목적으로 한다. 이를 위해 애착 이론의 관점에서 진세백을 분석하였다. 진세백은 자신의 감정을 여과 없이 표출하는 인물이다. 하옥주를 처음 본 순간 반하게 되는데 이는 주로 하옥주와의 스킨십으로 구현된다. 하옥주와 헤어지고 난 후에는 슬픔, 우울함, 분노를 표출하고 그리운 나머지 눈물을 흘리기까지 한다. 진세백은 하옥주와 이별과 만남을 반복하는데 일관적인 모습은 하옥주 곁을 떠나지 않으려 한다는 점이다. 하옥주에 대한 절(節)을 견지하며 그녀와 절대로 분리되지 않으려 한다. 감정을 진솔하게 표출하는 진세백의 행위는 당대 남성 유학자에게 요구하던 이념과는 거리가 먼 것으로서 경직되지 않은 발랄한 모습이다. 진세백은 애착 대상이던 부모를 여의고 하옥주를 새로운 애착 대상으로 삼지만, 그녀와의 반복된 이별로 극심한 분리불안 증세를 보인다. 결국 그러한 증세를 해소하는 것도 하옥주의 몫이다. 진세백은 남성영웅소설이나 여성영웅소설의 경직된 남성인물과는 거리가 있다. 대하소설에도 감정을 솔직하게 표현하는 호방형 인물이 등장하지만 진세백처럼 지속적으로 여성인물과 분리되지 않으려 하는 인물은 드물다. 전기소설이나 애정소설에서도 마찬가지로 진세백과 같은 감정선을 지닌 인물은 흔치 않다. 이러한 점에서 진세백은 소설사에서 매우 독특한 위상을 점하고 있다고 할 만하다.
