Free sugars are known to be effective to the quality changes of foods including brown pigment formation through amino-carbonyl reaction and also known to play an important role in the genetic or biological mechanism of formation and breakdown of carbohydrates. Furthermore, the change of free sugars are directly related to the cooking quality of foods containing large amount of carbohydrates. The present study was designed to utilize a kinetic approach to analyze the effect of temperature and water activity on the sucrose decrease in rice. The rice was controlled at a?? of 0.44, 0.52, 0.65, 0.75 using saturated salt solutions and then stored at 30, 40 and 50℃. Another portion of the sample of which the water activities were controlled was stored 30 and 50℃ alternately with 7days interval. Simplified kinetic models were used to obtain the various kinetic parameters for sucrose decrease in rice subjected to accelerated shelf-life tests(ASLT). The reaction of sucrose decrease was first order. The activation energies calculated from Arrhenius plot ranged 5.61-12.86 Kcal/moles and Q?? values were between 1.33 and 1.94. These kinetic parameters were then used to predict starch quality loss under the non-steady storage. Assessed from the above parameters the shelf-lives at 25℃, time to reach 50% loss in sucrose ranged 63 days to 300 days and showed decrease higher than in a??. The predicted shelf-lives at water activities tested were a little with increase actual values.

경기 K대학 치위생과 재학생들의 대학 진학시 학과선택 요인을 알아보고, 학과 만족도를 분석하여 치위생과 학과 경쟁력을 높이고 학생지도의 기초자료를 제공하고자 한다. 치위생과 입학 결정시 영향을 준 요인으로는 전반적으로 본인이 가장 높게 나타났으나 학년별로는 2학년이 77.5%로 가장 높았으며, 치위생과 선택이유로는 취업보장, 주위권유, 적성·흥미 순으로 조사되었다. 치위생과 학과만족도에서 강의실환경에 대해서는 전체 조사대상자 중 9.4%가 만족하다고 응답했고, 실험·실습기자재는 36.0%가 만족한다고 응답하였으며, 학우관계에서는 74.0%, 학과지도방침 38.9%, 치과위생사 직업만족도는 79.4%가 만족하고 있었다. 특히 조사대상자 중 다른 학년보다 2학년 학생들에게서 직업만족도를 제외한 다른 항목의 만족도가 가장 높게 나타나고 있다. 직업만족도는 1학년이 85.4%로 가장 높게 조사되었다. 휴학·자퇴를 고려한 경험유무에 대한 질문에서는 있다고 응답한 학생이 47.8%이었으며, 그 이유로 1학년은 경제적이유를, 2, 3학년은 적성이라고 응답하였다. 입학결정요인과 만족도와의 관계에서는 본인이 입학을 결정했을 때 재학만족도, 직업만족도, 학과지도방침, 전임교수에 만족한다고 응답한 경우가 가장 많았으며 진로계획에서는 취업이 가장 높았다. 학우관계와 만족도와의 관계에서는 학우관계에 만족한다고 응답한 경우 재학만족도, 직업만족도, 학과지도방침에 대한 만족도가 높은 것으로 분석되었다. 구강보건교육이 치위생과 선택에 미친 영향력에 대한 조사에서는 학년별 유의성은 보이지 않았으나, 전체조사대상 중 89.5%가 영향력이 보통이상이라고 응답해 높은 비율을 차지하는 것으로 나타났다. The purpose of this study is to identify the factors affecting selection of a major and the department satisfaction for improving the competitiveness of the dental hygiene department and providing the data for students guidance. The most influential person and factor in selecting a major is the person oneself(77.5% of the second-year students responded to the question) and the percentage of employment. The reaction of satisfaction with the classroom and practice facility indicates 9.4% and 36.0% in favor. 74.0% of surveyees is satisfied with classmates. In satisfaction with a course of department and profession, 38.9% and 79.4% of respondents answer in the affirmative. The second-year students of the respondents shows higher rate than other grades in .satisfaction with items above, except the satisfaction with profession. It appears that the freshman answered the most in that question. From the survey related to the experience of thinking over temporary absence from school or voluntary resignation, 47.8% of surveyees responded they had experienced thinking about that. The freshman answered the reason is financial difficulty and the second- and third-year students selected an aptitude. In the correlation coefficient of determinants for selection of college with the department satisfaction, when the determinant is oneself, the satisfaction with being at college, profession, a course of department, and teaching staff is high. In the correlation coefficient of classmates with department satisfaction, the students responding in the affirmative on classmate satisfaction had a high degree of satisfaction with being at college, profession, and a course of department. The experience of oral health education is not statically significant by grades to select the major, but 89.5% of the students majoring dental hygiene at K-college responded over average.

Eledctrophysiological phenomena of pyramidal cells in the CAI area of the dorsal hippocampus were recorded from and filled with neurobiotin in anesthetized rats. The electropharmacological properties of membrane as well as the cellular-synaptic generation of rhythmic slow activity (theta)were examined. The intracellular response characteristics of these pyramidal cells were distinctly different from responses of inteneurons. Pyramidal cells had a high resting membrane potential, a low input resistance, and a large amplitude action potential. A afterhyperpolarization was followed a single action potential. Most of pyramidal cells did not display a spontaneous firing. Pyramidal cells displayed weak inward rectification and anodal break excitation. The slope of the frequency-current relation was 53.4 Hz/nA for the first interspike interval and 15.9 Hz/nA for the last intervals, suggesting the presence of spike frequency adaptation. Neurobiotin-filled neurons showed pyramidal morphology. Cells were generally bipolar dendritc processes ramifying in stratum lacunosum-moleculare, radiatum, and oriens. Commissural stimulation discharged pyramidal cells, followed by excitatory and inhibitory postsynaptic potentials (EPSPs and IPSPs). The frequency of theat-related membrane potential oscillation was voltage-independent in pyramidal neurons. At strong depolarization levels (less than 30 mV) pyramidal cells emitted sodium spike oscillation, phase-locked to theta. The observations provide direct evidence that theta-related rhythmic hyperpolarization of principal cells is brought by the rhythmically discharging interneurons. Furthermore, the findings in which interneurons were also paced by rhythmic inhibitory postsynaptic potentials during theta suggest that they were periodically hyperpolarized by their GABAergic septal afferents.

Tetrahydroberberine-13-one was treated with ethylchloroformate to give the C_8-N bond cleaved product 1. On the treatment with Lawesson's reagent (LAS), chloroketone 2 derived from the hydrolysis of 1 afforded the thioketone 3. On the other hand, spirotype-chloroketone 4 was transformed to diaziridine 8 by a reduction, chlorination and aziridine introduction. Also, spirotype-chlorothioketone 6 was obtained from chloroketone 4.

Thrombohemorrhagic complications in chronic myeloproliferative disease(CMPD) including chronic myelogenous leukemia(CML) are not rare. Lower incidence of disordered hemostasis is reported in CML compared with other CMPD. The mechanism of thrombohemorrhagic complications might be a consequence of qualitative platelet abnormalites and prolonged bleeding time rather than that of thrombocytosis. Although defect of platelet function has been extensively investigated, there was no established consistent correlation between clinical bleeding and number and function of platelet. The most common site of bleeding complications in the CMPD is superficial mucosa. Bleeding in deep tissue and viscera is very unusual. We report a case of CML which developed a huge spontaneous retroperitoneal hematoma.

Chronic neutrophilic leukemia(CNL) is a very rare myeloproliferative disease, characterized by sustained mature neutrophilic leukocytosis with granulocytic bone marrow infiltration, high NAP(neutrophilic alkaline phosphatase) score and absence of philadelphia chromosome, It is frequently accompanied by hepatosplenomegaly, elevated serum vitamin B_12 and uric acid level. For the diagnosis of CNL, the leukemoid reaction, especially secondary to neoplasia, infection and autoimmune diseases, should be excluded. Since Tuohy's first description in 1920, more than 50 cases fullfilling the above criteria have been reported worldwide, and 4 cases in Korea. Several authors have demonstrated the defect of intracellualr killing in the mature neutrophil and this finding correlates well with the very high incidence of fatal infection, The hemorrhagic diasthesis in CNL is caused by functional abnormality of the platelet. This disease has tendency to transform to blastic crisis and acute leukemia as in other myeloproliferative disease, but characteristically shows frequent coexistence with multiple myeloma. Until now , the therapeutic trials in CNL have been disappointing. Hydroxyrea and busulfan can control hyperleukocytosis. On the basis of functional defect in neutrophil, alpha-2b-interferon has been tried and several reports have demonstrated the clinical and functional effect of interferon on CNL. CNL is very rate hematologic disease and there are few report about general aspect of disorder. We report here a typical CNL case presenting with splenomegaly and leukocytosis with a review of the literature.

남상순(Nam, Sang-Soon),홍정화(Hong, Jung-Hwa),차진화(Cha, Jin-Hwa) 한국회계정보학회 2016 한국회계정보학회 학술대회발표집 Vol.2016 No.2

본 연구는 가업승계 의사결정에 직접 영향을 미치는 요인에 관하여 검증하였으며, 또한 이해관계인 만족도의 매개효과 여부를 검증하였다. 이러한 연구목적을 달성하기 위하여 문헌적 연구방법과 설문지를 이용한 조사연구방법을 적용하였다. 설문대상자는 서울특별시와 경기도 일원의 세무사. 공인회계사 등 전문적인 지식을 갖춘 세무대리인과 가업승계 대상기업 근무자로서 이들에게 34개 설문항목을 리커트 7점 척도로 측정하는 설문지 800부를 배부하여 233부를 연구자료로 회수 및 활용하였다. 설문조사를 통하여 수집된 자료에 대한 신뢰성 및 타당성 검증에 이어 변수간 상관관계분석을 실시하였으며, 독립변수인 환경특성요인(사회 환경 특성, 구성원 특성, 상속세제 특성)이 가업승계 의사결정에 미치는 영향을 검증하기 위하여 다중회귀분석과 매개회귀분석을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 가업승계 관련한 환경요인별 특성이 가업승계 의사결정에 미치는 영향을 살펴보면, 사회환경 특성에서 외부환경과 내부환경, 구성원 특성에서 경영자 특성과 근로자 특성, 상속세제 특성에서 상속요건과 사후관리요건 모두 가업승계 의사결정에 유의한 영향을 미치는 것으로 나타났다. 구체적으로 가업승계 관련한 사회환경 특성에서는 기업의 내부환경 특성이 외부환경 특성보다 가업승계 의사결정에 미치는 영향이 큰 것으로 나타났고, 구성원 특성에서는 경영자 특성이 근로자 특성보다 가업승계 의사결정에 더 큰 영향을 미치는 것으로 나타났다, 또한 상속세제 특성에서는 상속요건보다 사후관리요건에 더 큰 영향을 받는 것으로 나타났다. 둘째, 가업승계 관련한 환경요인별 특성과 가업승계 의사결정간의 관계에서 이해관계인 만족도의 매개효과 여부를 살펴보면 사회환경 특성, 구성원 특성, 상속세제 특성 등 독립변수 모두 종속변수인 가업승계 의사결정에 이해관계인 만족도가 매개변수로서 유의하게 영향을 미치는 것으로 나타났다. 본 연구는 다음과 같은 한계점을 가지고 있다. 첫째, 본 연구의 응답자들이 가업승계대상기업과 세무대리인 모집단의 대표성을 확보할 수 없다는 한계가 있다. 주로 수도권에 소재하는 모집단을 대상으로 선정하여 전국적인 분포현황에 비례하여 설문을 시행하지 못한 한계가 있다. 또한 복잡한 세제상 요건에 관한 설문을 응답자들이 정확히 이해하고 응답하였는지 의문이 있어 연구결과를 일반화하는데 한계가 있다. 둘째, 가업승계 의사결정에 영향을 미치는 요인에 관하여 본 연구에서 채택한 변수 이외에 후계자 양성과정이나 가업상속재산을 포함한 상속재산 분배 등 다양한 변수들이 있을 수 있으나, 이러한 변수들을 포괄하지 못한 한계가 있다. There are some purposes of this study. First, how the environmental characteristic affects the decision making in family business successions. Second, how the satisfaction in interests affects both decision making and environmental characteristics related to family business successions. In order to attaining the study purpose, It considers the theoretical background and the precedent study through literature analysis by using the questionnaires. The study objects are corporations and tax delegates interested in the family business successions in Seoul and Gyeonggi Province. Their responses are used into the study though statistical analysis. The survey has 34 questions about the decision of family business successions, satisfaction in interests and environmental characteristics related to family business successions. Also, they are set by Likert 7 points. The study sums it up in a word just like below. First, in the affection of decisions in family business successions to environmental factor characteristics, the social environmental, members, inheritance tax characteristics have similar affection to decisions of family business successions. Second, it is found that the satisfaction of interests in independent variables, the three above characteristics, has significantly affected to a family business successions by looking into the mediated affects or not. This study has some limitation as shown below. First, it cannot make sure that the response of our questionnaires is the representative of tax agency and corporation which is trying to succeed the business to their family. Also, there could make the mistake of hasty generalization for that the responses do not understand exactly to complicated tax requirements. Second, What does family business inheritance decision makes cause and effect that family business inheritance was able to investigation which found differences between the object of company and Tax agency from survey. However, the investigation was not enough to found limits of causes. Third, the research show bounded of family business inheritance decision to cause and effect such as, training successor or succession to a family occupation property which include distribution of family occupation. Finally, the study try to found that what family business inheritance affect decision in relation of environmental family business by logical reason. However, the study need to provide advanced research which need to base on specific relation.
