        Polymorphic Phase Transition and Temperature Coefficient of Capacitance of Alkaline Niobate Based Ceramics

        배선,신혜경,손은영,임인호 한국전기전자재료학회 2013 Transactions on Electrical and Electronic Material Vol.14 No.2

        0.95(Na0.5K0.5)NbO3-0.05BaTiO3 + 0.2wt% Ag2O (hereafter, No excess NKN) ceramics and 0.95(Na0.5K0.5)NbO3-0.05BaTiO3 + 0.2wt% Ag2O with excess (Na0.5K0.5)NbO3 (hereafter, Excess NKN) were fabricated by the conventional solid state sintering method, and their phase transition properties and dielectric properties were investigated. The crystalline structure of No excess NKN ceramics and Excess NKN ceramics were shown characteristics of polymorphic phase transition (hereafter, PPT), especially shift from the orthorhombic to tetragonal phase by increasing sintering temperature range from 1,100℃ to 1,200℃. Also, the temperature coefficient of capacitance (hereafter, TCC) of No excess NKN ceramics and Excess NKN ceramics from -40℃ to 100℃ was measured to evaluate temperature stability for applications in cold regions. The TCC of No excess NKN and Excess NKN ceramics showed positive TCC characteristics at a temperature range from -40℃ to 100℃. Especially, Excess NKN showed a smaller TCC gradient than those of Excess NKN ceramics in range from -40℃ to 100℃. Therefore, NKN piezoelectric ceramics combined with temperature compensated capacitor having negative temperature characteristics is desired for usage in cold regions.

      • 흰쥐 하수체 적출이 그 장간막 비만세포에 미치는 영향

        배선,이갑재 中央醫學社 1972 中央醫學 Vol.22 No.4

        Mature male Swiss albino rats, weighing about 200gm each, were divided into groups of normal, hypophysectomy, and sham operation, and the hypophysectomized group was further divided into five subgroups of 1-, 2-, 3-, 5-, and 7-postoperative days. The authors then observed the number as well as the structure of the mast cells in the mesentery with the following results: 1. In the normal group, the number of mast cells appearing in the mesentery was on an average 32.73 per view field of 160X, about 7. 3 percent of which were degranulated cells. 2. In the group of sham operation, the average number of mast cells and the ratio of that of degranulated cells was similar to the value in the case of the normal group. 3. In general, in the group of hypophysectomy no marked change was observed in the number of mast cells, and only the 7-day subgroup showed a significant decrease(17%). The marked change was increase in the number of degranulated cells and this number increased with the lapse of time, finally reaching, in the 7-day subgroup, the level twice as large as that of the normal group. In addition, the shape of a cell took a somewhat irregular form with the passing of time. Furthermore, the size of granules in the cytoplasm became uneven, and the stain ability turned from metachromatic to orthochromatic, showing weak staining in general. Vacuolation was observed to increase. 4. To sum up the above, it can be concluded that the mast cells in the mesentery are not affected in number by hypophysectomy, but undergo notable structural changes due to this operation.

        천국천사들의 수학

        배선복(Bae Sun Bok) 철학연구회 2013 哲學硏究 Vol.0 No.103

        St. Anselm treats in his work Cur Deus Homo, Book 1, Ch.16-18 the possibility of fulfillment of membership of heavenly kingdom through an equal proportional division of fallen angels andfaithful human beings. Anselm argues for the constitution of heavenly membership, but he envisions that the membership of heavenly kingdom as the perfect number is a zero sum game. The perfect number goes neither minus nor plus in its left or right equation, but its membership comes up as long as comes down. (Angels/Humans)are such arithmetical formulas, in which St. Anselm arrives to conclusion, “Φ ∧ Ψ¬) ∨ (¬Φ ∧ Ψ)) ⊇ Ψ*”, where Φ belongs to member of angels, Ψ to human beings, but to Ψ* is required to add extra human beings as arrogant peoples or another angels. This conclusion can be semantical interpreted that rational beings are more than angels in the heavenly kingdom.According to methodological approach by D. P. Henry, D.Walton, S. L. Ukelmann, P. King, etc., who discovered agent logic in Anselm, I try to show a positive argument for the arrogant peoples and another angels who want to enter into the kingdom of heaven. Given two alternative attitudes for agents that they can choose facere esse or facere non esse, we can get q* in Ψ*, when they do truth making p ∧ ¬p or don`t truth making p ∧ ¬p. It means that another angels can get chance to enter into the kingdom of heaven.

        정책의제형성에 있어서 참여자에 관한 연구 - 다문화가족지원법 중심으로 -

        배선,김승일,Bae, Seon-Sik,Kim, Seung-Il 한국정보전자통신기술학회 2015 한국정보전자통신기술학회논문지 Vol.8 No.2

        본 연구는 1980년 이후부터 국제이주의 현상이 세계화, 다변화로 외국인 근로자들의 노동시장의 유입과 여성결혼이민자 증가로 인해 '다문화가족지원법'을 탄생시키게 된다. 다문화가족이라는 사회문제가 공공의제로 부각하여 '다문화가족지원법'의 제정으로 연결될 때 참여자들은 누구인가?를 알아보고자 한다. 또한 사회문제 중에서 정부의 공식의제로 확정하여 추진하는 과정에는 동원형, 외부주도형, 내부접근형의 3유형에서 동원형을 선택하여 설명할 것이다. 사례의 특성을 염두에 두고 기존 이론과 모형을 바탕으로 분석할 것이며, 연구논문과 서적, 신문, 일간지, 선거공약, 시민단체, 인터넷, 세미나자료 등을 사용하는 사례분석방법을 택하여 연구할 것이며, 시간적범위는 2003년 11월 21일 "이주노동자 추방반대 재외동포법 개정하라" 한 시점에서 '다문화가족지원법안(대안)'을 제271회 임시국회 제7차 본회의에서 재석 165인 중 165인 찬성으로 입법되는 2008년 2월 19일까지로 한정짓는다. The phenomenon of international migration since the 1980s comes to be born 'multi-cultural families support law' due to the foreign workers' inflow into labor market and to a rise in married female immigrants caused by globalization and diversification. Accordingly, the purpose of this study is to examine who are participants? given being led to the enactment of 'multi-cultural families support law' by which the social issue called multi-cultural family is highlighted as the public agenda. Also, the mobilization will be selected and explained among three types in mobilization model, outside initiative model, and inside access model in the process of driving by confirming it as the government's formal agenda out of social issues. With having the case characteristics in mind, the aim is to research by choosing a case analysis method that uses research theses & books, newspaper, daily newspaper, election pledges, civic group, internet, and seminar data based on the existing theory and model. The temporal scope is limited to the one from the time as saying "revise the Overseas Korean Act of opposing the banishment of migrant workers" in November 2003 to February 2008 when 'multi-cultural families support bill(alternative plan)' is legislated with agreement by the 7th plenary session for the 271th provisional session of the National Assembly.

        Radiation Treatment in Pathologic N0-N1 Patients Treated with Neoadjuvant Chemotherapy Followed by Surgery for Locally Advanced Breast Cancer

        배선,박원,허승재,최두호,남석진,임영혁,안진석 한국유방암학회 2012 Journal of breast cancer Vol.15 No.3

        Purpose: This study evaluated the treatment results and the necessity to irradiate the supraclavicular lymph node (SCN) region in pathological N0-N1 (pN0-N1) patients with locally advanced breast cancer treated with neoadjuvant chemotherapy (NAC) followed by surgery and radiotherapy (RT). Methods: Between 1996 and 2008, 184 patients with initial tumor size >5cm or clinically positive lymph nodes were treated with NAC followed by surgery and RT. Among these patients, we retrospectively reviewed 98 patients with pN0-N1. Mastectomy was performed in 55%. The pathological lymph node stage was N0 in 49% and N1 in 51%. All patients received adjuvant RT to chest wall or breast and 56 patients (57%) also received RT to the SCN region (SCNRT). Results: At 5 years, locoregional recurrence (LRR)-free survival, distant metastasis-free survival, disease-free survival (DFS), and overall survival rates were 93%, 83%, 81%, and 91%, respectively. In pN0 patients, LRR was 7% in SCNRT−group and 5% in SCNRT+ group. In pN1 patients, LRR was 7% in SCNRT- group and 6% in SCNRT+ group. There was no significant difference of LRR, regardless of SCNRT. However, in pN1patients, there were more patients with poor prognostic factors in the SCNRT+ group compared to SCNRT- group. These factors might be associated with worse DFS in the SCNRT+ group, even though RT was administered to the SCN region. Conclusion: Our study showed the similar LRR, regardless of SCNRT in pN0-pN1 breast cancer patients after NAC followed by surgery. Prospective randomized trial is called for to validate the role of SCNRT.

        새만금지역(서해안)을 중심으로 한 이주노동자들의 문화적응 간 비교 연구

        배선식 ( Bae Seon-sik ) 한국도서학회 2016 韓國島嶼硏究 Vol.28 No.3

        본 연구는 새만금지역(서해안)에 거주하고 있는 중국, 베트남, 캄보디아의 이주노동자들을 대상으로 문화적응의 정도를 규명하고자 하였다. 연구의 목적을 달성하기 위하여 서베이 방식을 채택하였으며, 분석에 사용한 설문지는 인구통계학적 변인 측정 영역, 문화적응 영역으로 총 21문항의 249개이며, 측정도구는 SPSS(Ver.24) 통계프로그램을 이용하였다. 주요 변수들의 특성 및 문화적응 정도를 파악하기 위해 빈도분석과 기술통계분석을 실시하고, 종속변수의 추이를 파악해 보기 위해 t-test와 one-way ANOVA를 실시하였으며, 문화적응에 미치는 영향에 관계를 알아보기 위해서는 다중회귀분석을 실시하였다. 이상과 같은 연구방법 및 절차를 통해 다음과 같은 결론을 도출하였다. 첫째, 이주노동자들의 문화적응에 미치는 영향의 분석결과, 유의확률은 p=0.000으로 통계적으로 유의한 차이가 있는 것으로 나타났으며, 중국(m=3.4373), 캄보디아(m=2.8081), 베트남(m=2.3744) 순이었다. 또한 중국은 3군집 간의 상당한 차이를 보이고 있다. 이와같이 한국에 있는 중국 이주노동자들이 가장 높은 비율을 차지하고 있는 것은 지리적인 접근성이 크다는 이유 때문만은 아닐 것이다. 역사와 문화적 동질성이 같은 조선족 출신 배경과 재중 동포의 이주노동자들이 한국을 선택하는 데 긍정적인 작용을 했을 것으로 추측해 볼 수 있다. 둘째, 이주노동자들의 인구통계학적 특성이 문화적응에 미치는 영향에서 학력, 체류기간의 변수들을 분석한 결과 유의미한 영향관계가 나타났지만, 체류기간과는 영향관계가 없는 것으로 나타났다. 본 연구는 한국사회의 이주노동자는 장기적·영구적 이민이 아닌 일시적·단기적 체류이기는 하지만 이주노동자 집단을 더 이상 잠시 머물렀다 떠나는 노동력으로만 간주해서는 안 되며, 이주노동자들을 한국 사회 구성원으로 받아들이려는 노력이 절실하다. 정주화 현상에 심도 있는 대처를 위한 이주노동자들의 문화적응을 학문적으로 연구해야하는 현실적 동기를 부여하고자 한다. 이주노동자들의 문화적응에도 긍정적인 영향을 미쳐, 한국 사회의 구성원으로 포용이나 통합 될 수 있는 기회가 되며, 공동체적 가치존중과 통합을 위한 책임과 의무를 이행하는 단초가 될 것이다. 또한 사회통합 방안을 위한 이주노동자 정책을 수립하고 집행하는데 유용한 기초 자료에 도움이 될 것으로 기대한다. The purpose of this study was to examine the acculturation of immigrant workers from China, Vietnam and Cambodia who resided in the region of Saemangeum(the west coast). A survey was conducted to serve the purpose of this study. The questionnaires used in this study consisted of two sections and 21 items. The two sections respectively dealt with demographic characteristics and acculturation. Answer sheets from 249 respondents were analyzed. The instrument used in this study was a statistical package SPSS 24. Frequency analysis and descriptive statistics analysis were made to determine the characteristics of the subjects and the degree of their acculturation. T-test and one-way ANOVA were carried out to figure out the trend of the dependent variable. Also, in order to find out the influential relationships between acculturation and related variables, a multiple regression analysis was utilized. The findings of the study were as follows: First, as a result of analyzing the degree of acculturation of the immigrant workers, statistical results at the p=0.000 level of significance were obtained. Immigrant workers from China (m=3.4373) were the best, followed by workers from Cambodia(m=2.8081) and those from Vietnam(m=3.3744). There were great disparities among all three groups of immigrant workers. The rate of immigrant workers from China was highest in South Korea, and it seems that geographic accessibility is not the only reason. Ethnic Koreans living in China and Korean-Chinese people may have been stimulated to choose Korea because of their ethnic background. Second, as for the influence of demographic characteristics on immigrant workers` acculturation, the academic credential and length of stay was analyzed. Academic credential turned to have a significant influential relationship while the length of stay had none. Although immigrant workers stay in Korean just on a temporary basis, they should no longer be viewed as labor force that will leave after a short while. It is urgent that we accept them as members of the Korean society. Thus, coping with the settlement of immigrant workers should discreetly be considered. This study intends to prove the oughtness of academic research on the acculturation of today`s immigrant workers. The research efforts are expected to affect the acculturation of immigrant workers in a positive way, and provide an opportunity for them to be accepted as members of Korean society or at least as those integrated to it. Our final goal is to accelerate the fulfillment of responsibilities and obligations for the realization of community-oriented value and social integration. Also, this study is expected to provide useful information on how to formulate and execute immigrant worker policies and facilitate their social integration.
