DNA sequences of nrITS regions obtained from 49 accessions representing 12 species and one variety within the section Adonanthe of the genus Adonis were analyzed to test the previous intra-sectional classification system and to determine their phylogenetic relationships. The results showed that the seven accessions of A. amurensis Regel et Radde included in the present study did not form a monophyletic group, as some of the accessions showed a close relationship with the Japanese endemic species A. ramosa Franch., which implies that the current species delimitation and identification of A. amurensis is problematic. Adonis pseudoamurensis W. T. Wang, which is frequently misidentified as A. ramosa in Korea, formed a segregated group, which suggests that they should not be considered as conspecific taxa. Accessions from A. shikokuensis Nishikawa et Koji Ito, A. multiflora Nishikawa et Koji Ito, and A. pseudoamurensis formed a clade, but monophyly of each species was not evident. The nrITS data did not support the classification system proposed by Wang, who classified sect. Adonanthe into four series, as most of these were found to be either polyphyletic or paraphyletic.

신정부의 탈원전 정책에 의해 급속하게 원자력계를 둘러싼 환경이 변하고 있다. 지금까지의 정부가 추진해온 원자력 중심의 전원계획이 신재생에너지 확대를 위한 계획으로 변화되어 가고 있다. 그리고 이러한 정부 정책 추진의 중심에는 매우 높은 대통령 지지율이 기반이 되고 있다. 하지만 여러 여론 조사 결과를 살펴보면 대통령은 약 65% 내외의 지지를 기록함에도 불구하고 원자력 활용에 대해서는 찬반 의견이 매우 팽팽하다. 즉, 원자력에 대한 이슈가 최근 에너지, 경제 문제가 아닌 정치 이슈가 된 상황에서도 원자력에 대해 지지를 보여주는 집단이 존재한다는 것을 뜻한다. 하지만 원자력을 지지하는 일반인들이 정치권과 탈핵 시민단체에서 원자력 분야를 소위 '적폐'로 규정하고 '원자력 마피아'로 명명한 상태에서 원자력에 대해 드러내놓고 지지하는 것은 쉽지 않다. 따라서 본 연구는 우리나라의 어떠한 계층에서 원자력을 지지하는지, 즉 'Shy Nuclear'를 찾고 이 지지층들의 특징에 대해서 분석하였다. 지지층 분류를 위해서 머신러닝의 분류분석 기법인 Decision Tree Analysis(의사결정나무) 방법론을 활용하였다. 분석 결과 Shy Nuclear를 결정하는 주 요인은 거주지역으로 나타났다. 아울러 수도권에 거주하고 있는 사무/관리/전문직/퇴직자 집단이 가장 원자력에 높은 호감도(긍정 76.1%)를 보여주었다.

The purpose of this study is to determine the self-image of fathers who have younger children. For this purpose, this researcher conducted profound interviews with 6 fathers residing in P city who have young children in order to identify images that they were having about themselves. The interviews were conducted from Aug. 7th to 30th, 2012 over a total of 3 sessions for each of the subjects on the basis of 1 session a week and 1 or 1 and a half hours per session. The findings of this study showed that the subjects were having different self-images that could be largely classified into five categories, 'father who can't do for family as much as he wants', 'father who has not yet been successful', 'father who feels lonely under his own duty and responsibility, 'father who sacrifices himself for family' and 'father who is different from fathers of the past'. Based on the analysis and discussions of these findings, this study suggested how fathers having younger children should do to have a better image about themselves.

As a part of integrated study for technical communication between consumer and manufacturer of functional clothing, functional clothing consumers were categorized based on their perception of the functional outdoor jacket and the differences in the source of information and use of hang-tag were examined according to the groups. Questionnaire survey was conducted on 472 males and females in their 20s to 60s, who have experience of purchasing functional outdoor jackets. Perception of functional outdoor jackets was classified into four factors ('functionality', 'price', 'experience/knowledge' and 'brand/design') and the respondents were categorized into three groups according to the factors: 'unconversant/brand & design pursuing group', 'conversant/function pursuing group' and 'high-priced products preferring group'. 'Unconversant/brand & design pursuing group' was composed of high rate of office workers and students in their 20s and 30s who use internet most frequently as source of information while 'conversant/function pursuing group' was composed of high rate of professionals in their 40s and 50s who make the most frequent use of information on hang-tag. 'High-priced products preferring group', which has high rate of the elderly in their 60s and housewives, obtain their information mainly from salespersons. 'Unconversant/brand & design pursuing group' was satisfied with functional information more than other two groups and 'conversant/function pursuing group' concerned for the hang-tag and required more explanation of terminology used in hang-tag. The results effectively explained the features of consumer groups and their different responses toward the information of functional outdoor jacket.

The purpose of this study is to try to structuralize the perception of the mothers of science-gifted elementary students using the concept mapping approach. The mothers who participated in this research had children who were 5th and 6th graders selected as science-gifted by a regional education office, a science high school and two national universities in a city. One of the authors interviewed 26 mothers, and extracted 50 general statements of their perceptions about the career path of their children. Ten mothers who participated in interviews sorted a shuffled pack of statement cards. The categorization of the statements into the dissimilarity matrix was carried out by SPSS multidimensional scaling analysis and hierarchical cluster analysis to generate a conceptual diagram. After that 140 mothers rated each statement using a Likert-type response scale from one to five. The result showed six clusters of parental views such as were 'Burden of private education, grades and going to the next grade,' 'Thinking about career guidance in gifted education and school,' 'Parental roles in child career education,' 'Difficulties in career guidance at home,' 'Demand for strengthening the parental capacity for career guidance,' and 'Demand for social support.' 'Demand for social support' obtained the highest sympathy from mothers of elementary science gifted.

In this study, radiation exposure doses were measured in the course of clinical practice of radiation workers, radiological technologists in the radiation-related worker group, and preliminary-radiological technologists who were classified as frequent visitors. Radiological technologists who worked in the radiation area of C University Hospital in Incheon for a year from January 2021 and 121 students who completed clinical practice at the same medical institution from July 1 to August 31 were the subjects of the study. The nominal risk factor based on ICRP 103 was used to evaluate the probability of side effects due to the exposure dose to the lungs, which are organs at risk of damage due to radiation exposure dose. During the clinical practice period, radiology students, who were classified as frequent visitors, had a surface dose of 0.98 ± 0.14 mSv and a deep dose of 0.93 ± 0.14 mSv. In other words, 6.7 per 1,000,000 for shallow dose and 6.4 per 1,000,000 for deep dose were found to have side effects due to exposure to the lungs. This is a value in terms of exposure dose in one year. Considering that the radiation (science) education course is 3 or 4 years, systematic management and attention to prospective radiation workers who are going to clinical practice are required, and the stochastic effect of radiation In relation to this, it is considered that it will be used as basic data for radiation safety management.

Delayed treatment of acute cardiovascular and cereb-directrovascular diseases is related to poor prognosis and sequelae. For rapid and adequate treatment, role of prehospital emergency dispatchers for adequate triage and selection of hospital is important. In several advanced countries, emergency dispatchers use standardized protocols for decision of rescuer resources or distribution of patients at each hospital. ut, there has not been developed standardized protocol for emergency dispatchers in Korea. We developed standardized protocol based on NHS-direct and CTAS system for triage of symptoms of chest pain and Stroke. Groups with standardized protocol and without protocol was compared to triage result at emergency department which patient visited. The accuracy of triage on chest pain was 70.0% in group A, 94.0% in group B(p<0.01). The accuracy of triage in stroke symptoms was 64.2% in group A, 84.6% in group B(p<0.01). Conclusion: In this study, the accuracy of telephone triage with the protocol was more accurate than without the protocol. But, more studies are needed to generalize the protocol in South korea.

Many persons, both children and adults, suffer from impaired hearing. The handicaps that arise from this are economic, educational and above all, social. These persons need help, both medical and educational. In order to plan facilities for the medical treat ment, the rehabilitation, and the special education required by those with impaired hearing, we must know how many persons with hearing problems there are and the severity of their handicaps. The first step in knowing these is to devide hearing impairent into categories of handicap. Historically, since Beasley (1940) proposed progressive stages of deafness in terms of social disability, there was no well organized classification. of hearing handicap except related material from Huzing (1959) and Silverman (1960). In 1965, Goodman advocated a guide hearing threshold levels and degres of relating hearing impairment. During recent one year, on the bases of Goodman classification of hearing impairment and the report from Illinois Comission on children (1968), we have studied about hearing handicaps and speech life for the 180 cases, who visited to our otolaryngology department with hearing impairment. Now, we report the results of study with the referred references.

Purpose : This report is the result f retrospective analysis for children who received prophylactic cranial irradiation combined with intrathecal chemotherapy. Materials and Methods : Ninety children with ALL who had got bone marrow remission after induction chemotherapy received PCI. All but 3 children were treated with a dose of 1800 cGy as a standard regimen. While the PCI was given, all patients received intrathecal chemotherapy. Results : Nine of 90 patients experienced CNS relapse during the duration of follow-up ranged from 36 to 96 months (median 60 months). Three children experienced BM relapse prior to CNS relapse. Therefore, CNS relapse rate as the first adverse event was $6.7\%$. Median time interval of CNS relapse was 16 months from the first day of hematologic complete remission. Eighty-nine percent of patients who had CNS relapse were associated with hematologic relapse. and $78\%$ of CNS relpase occurred during maintenance chemotherapy (on-therapy relapse). The CNS RFS at 2 and 5 years are $68\%$ and $42\%$, respectively with median of 43 months. The Prognostic factors affecting CNS RFS are initial WBC count (cut-off point of 50,000/ul), FAB subtype and CALGB risk criteria. The DFS at 2 and 5 years are 61 and $39\%$, respectively with median of 34 months. The prognostic factors affecting DFS are initial WBC count (cut-off point of 50,000/ul), FAB subtype, POG and CALGB risk criteria. Conclusions : In our study, $6.7\%$ of CNS relapse rate as a first adverse event was comparable with other studies. Various risk criteria was based on age at diagnosis and initial WBC count such as POG and CALGB criteria, had prognostic significance for CNS RFS and DFS. Prospective randomized trial according to prognostic subgroup based on risk criteria and systematic study about neuropsychologic function for long term survivors, are essential to determine the most effective and least toxic form of CNS prophylaxis.
