In reference to the ISO-4037 and ANSI N13.11, appropriateness of the shielding and collimating system, and suitability of the irradiation and its environmental conditions of a 20 Ci Cs-137 gamma-ray irradiator installed in Korea Institute of Nuclear Safety(KINS) were investigated. Upon the installation of the irradiator, condition of collimator alignment and virtual beam cross section were examined by use of a portable He-Ne laser. In order to evaluate the fitness of the secondary(scattered) to primary ratio of the collimated gamma-ray beam from the irradiator in light of ISO and ANSI requirement, the measurements of the secondary to primary ratio were performed by use of a cavity type ion chamber which had been calibrated in a calibration laboratory that maintains reliable traceability. For the theoretical assessment of the gamma-ray field the collimated beam were divided into fifteen sectors and for each sector the secondary to primary ratio and the gamma-ray spectrum was simulated by means of Monte Carlo method. The outcomes were compared with the experimental results, and cause of scattering and the existence of alleged modifying factors in the irradiator were examined.

日本語 敎材 硏究(Ⅰ) : Centering Around Sentense Pattern of Conjugation and Declension of Predicates 連用形의 文型을 中心으로

張明俊 慶尙大學校 1979 論文集 Vol.18 No.2

In Japannese sentences and everyday speech Conjugation and declension of predicates are most frequently used. This treatise is concerned with selecting various sentence patterns of conjugation and declension of Japanese predicates from every Japanese teaching material available and analyzing them. And it is also concerned with arranging systematically sentence patterns of conjugation and declension of Japanese predicates whereby it may be of some service to choosing proper teaching materials and compiling teaching materials useful to students. This treatise intends to include all the sentence patterns of conjugation and declension of predicates; and the principal patterns are as follows: 1. Various sentence patterns of conjugation of verbs. 2. Those of declension of adjectives. 3. Diverse sentence patterns of conjugation of adjective verbs. 4. Those of conjugation of auxiliary verbs. In presenting the abundant exemplary sentences, the present writer took much care to give as various kinds of patterns as possible and avoid overlapping of similar patterns. As a result of this investigation the present writer could make clear that the frequency of a particular one in each sentence pattern and that of a particular word in one sentence pattern were too high. And in this treatise the grammatical system of conjugation and declension of predicates in Japanese teaching material is also illustrated.

張明俊 慶尙大學校 1980 論文集 Vol.19 No.2

This study is to analyze sentence patterns in the Japanese text as mentioned above. The text is being widely used in most colleges and institutions for students who want to learn Japanese. the text being most fit for Koreans studying Japanese. And the text is so compiled that it contains correct Japanese grammar in comparatively systmac order. This study is focussed on the analysis of sentence patterns with a special reference to coniugation of each part of speeth attempts to analyze and classify most important sentence patterns which have been selected from the text, and to present other sentence patterns which are relevant to those sentence patterns. Through examining the frequency in use of sentence patterns, it can be shown how far the sentence patterns in the text, compared with those which have been collected by the present author, are useful and how systematically they are arrangde in view of learning efficiency.

日本語와 韓國語의 表現上의 차이에 관한 硏究

張明俊 慶尙大學校 1978 論文集 Vol.17 No.2

The Korean language and the Japnese language must be the same lineage in the view of the historical and geographical relation in the bothe languages. The similarity can be recognized to a certain extent from theuse fo chinese characters, auxiliary words and the order of words, and is all the more in such ways even in grammatical structure. However, We think the Japanese language, as a foreign language to us, may perhaps have dissimilarities much or less. As the both languages have its own meaning and structual characteristics, to inquire into it, there are some cases that the order of words is different, and many dissimiliarities can be found in the use of chinese characters and auxiliary words, and still more we can feel the difference of the expression way in the both languages. This thesis deals with the selection and arrangement of parts which are appeared problems based on the each partof speech in the Japanese language and moreover describes on how it is different in expression with the Korean language. Its important object is to give better studies to the students who learn the Japanese language, and to have the teachers of the Japanese language interested in such matters. Because the parts suggested in this thesis are these which the study the Japanese languge have their questions in their studies. Accordingly, the author desires that the better systemic and efficint method for the study of the Japanese language and a teaching method shall be presented through the thesis.

Keratins are characteristically present in all keratinizing and nonkeratinizing epithelial cells and their neoplasms. They consist of at least 19 different polypeptides ranging from 40 to 69 kilodaltons, which are developmentally related to specific epithelial cell types. Keratins of high and intermediate molecular weights are readily demonstrated in squamous cell carcinomas, which are characteristically rich in tonofilaments and tonofilament-desmosome complexes. Keratins of low molecular weights are expressed in adenocarcinoma including renal cell carinoma, hepatocellular carcinoma, small cell carcinoma, and carcinoid tumor. These tumors do not reveal any tonofilaments and sacrcely show discrete filaments on electron microscopy. An immunoperoxidase technique employing antibody to keratin was used to study distribution and staining pattern of keratin filaments in benign and malignant epithelial tumors (20 squamous cell carcinomas, 20 gastric adenocarcinomas, 20 transitional cell carcinomas and 15 non-neoplastic epithelia). These immunohistochemical results were compared with ultrastructural features of neoplastic diagnosis of squamous cell carcinoma, adenocarcinoma and transitional cell carcinoma, and estimation of degree of differentiation. The results are as follows : 1. The squamous epithelium, glandular epithelium and transitional epithelium disclosed the positive reaction for keratin. 2. Squamous cell carcinoma and transitional cell carcinoma exhibited positive reaction for keratin. 3. Gastric adenocarcinoma showed uniformly negative or weakly positive reaction for keratin. 4. On electron microscopy, heavy bundles of tonofilaments and desmosomes were more frequently encountered in well differentiated squamous cell carcinoma, In poorly differentiated squamous cell carcinoma, a few tonofibrils and desmosome were noted. 5. In the adenocarcinomas, the intermediate filaments were arranged randomly as nonaggregated, short filaments spread throughout the cytoplasm, although occasionally they formed a perinuclear whorl. These filaments did not become aggregated to form tonofilaments. 6. On the immunogold labeling for keratin of low molecular weight areas in gastric adenocinoma, in tense labeling of intermediate filaments for keratin was noted. From the above result, ultrastructural and immunohistochemical study on malignant epithelial cell were useful in differential diagnosis of squamous cell carcinoma, adenocarcinoma and transitional cell carcinoma, and estimation of degree of differentiation. It was also proved that immunogold labeling technique was especially valuable for diagnosis of vague case which showed negative or weakly positive reaction in immunohistochemical stain.

We have experienced of a case of acute renal failure after the administration of rifampicin. The patient was a 23 years old male and had suffered from pulmonary tuberculosis since Aug. 1979 and had been treated with rifampicin, isoniazid and streptomycin for 1 year. When the second dose of rifampicin was given to the patient because of recurrence of Feb. 1981, headache, nausea and high fever developed, and it was discontinud. On Jun. 1981, 4 days before admission, rifampicin was tried again, but 20 minutes after ingestion, headache, nausea and vomiting developed, then oliguria followed. Physical examination and laboratory findings showed the pictures of acute renal failure. Peritoneal dialysis was performed for 3 times. After 10 days of oliguric phase, urinary output increased and general condition improved. He was discharged at 27th HD with complete recovery.

본 연구에서는 산림청을 대상으로 2006년부터 2012년까지 2년을 주기로 정기적으로 조직문화에 어떠한 변화가 일어났는지를 조직문화진단을 통해 실증적으로 분석하였다. 진단을 통해 조직의 건강성을 지속적으로 유지하면서 조직발전이 이루어지기 위해 필요한 전략들을 조직문화에 대한 변화관리전략을 중심으로 모색하였다. 분석결과를 살펴보면 1차 진단에서는 현재 수준의 조직문화 유형에서 시장지향문화가 가장 강한 것으로 나타났고, 상대적으로 혁신지향문화가 가장 약한 문화유형으로 인식하고 있는 것으로 나타났다. 그리고 2차 진단, 3차 진단, 4차 진단 모두 시장지향문화가 가장 강한 것으로 나타났고, 혁신지향문화가 가장 약한 문화유형으로 인식하고 있는 것으로 나타났다. 직급별로 살펴보면 상위직 직원들의 조직문화에 대한 진단을 비교분석해 보면, 상위직의 경우 노무현 정부의 현재수준에서는 관계지향문화를 이명박 정부 때에는 시장지향문화를 가장 강한 조직문화유형으로 인식하고 있었고, 2010년의 3차 진단을 제외하고는 혁신지향문화를 가장 약한 조직문화유형으로 인식하고 있는 것으로 분석되었다. 또한 미래의 바람직한 조직문화유형에 대해서는 관계지향문화가 현재수준과 같이 가장 강한 조직문화유형이 되기를 희망하고 있었고, 가장 약한 조직문화유형은 위계지향문화가 되기를 원하고 있는 것으로 분석되었다. 직의 경우 현재수준에서는 시장지향문화를 가장 강한 조직문화유형으로 인식하고 있었고, 혁신지향문화를 가장 약한 조직문화유형으로 인식하고 있는 것으로 분석되었다. 또한 미래의 바람직한 조직문화유형에 대해서는 관계지향문화가 가장 강한 조직문화유형이 되기를 희망하고 있었고, 가장 약한 조직문화유형은 시장지향문화가 되기를 원하고 있는 것으로 분석되었다. 조직문화에 대한 진단과 분석을 통해 나타난 결과를 바탕으로 하여 조직문화 관리방안을 제시해 보면 다음과 같다. 첫째, 일관성 있는 조직문화의 강도는 조직에 안정감을 가져다준다는 측면과 문화적 동일성으로 인해 정책 및 사업전반에 대한 명확한 의사전달과 의사결정에서의 합의 또는 공감대 형성이 용이하다는 장점이 산림청에서는 아주 긍정적으로 작용하고 있다는 것을 시사해 주고 있다. 둘째, 바람직한 미래문화와 현재문화 사이에 존재하는 차이(gap)의 강도에 대해 확인할 수 있었으며, 이에 대한 처방이 필요하다는 것을 알 수 있다. 셋째, 조직문화를 통해 조직이 발전하고자 하는 방향에 대해서 직원들 모두의 공감대를 형성하는 작업들도 병행될 필요가 있다는 것을 조직의 기관장이 인식하는 것이 필요하다. 마지막으로 조직의 지속적인 발전과정을 확인하기 위해서는 현재시점에서의 조직문화에 대한 연구보다는 여러 해에 걸친 시계열적 관점에서의 조직문화에 대한 연구가 더욱 활성화될 필요가 있다. This study conducts organizational diagnosis and analyzes changes in organizational culture of the head office of Korea Forest Service in the span of 2-year, from 2006 to 2012. Through the diagnosis this study looks for strategies for maintaining the organizational healthiness of KFS, which are centered on managing organizational culture sustainably. Comparative analysis of the first, second, third, and fourth diagnosis results on organizational culture of the public officials of KFS shows that market culture was strongest at the current level of the first diagnosis. On the other hand, adhocracy culture was the least perceived type. In the second, third, and fourth diagnoses, market culture is the strongest and adhocracy culture was the least perceived culture. high-ranked officials perceived clan culture as the strongest culture at the current level during the Roh Moo-Hyun Government and market culture during the Lee Myung-Bak Government. Except the third diagnosis in 2010, they perceived adhocracy culture as the weakest. Comparative analysis on lower position officials’ diagnosis on organizational culture shows that they perceived market culture as the strongest culture at the current level and adhocracy culture was weakest culture. As for future desirable culture, they hoped for clan culture to be the strongest culture and market culture to be the weakest culture. The measures to manage organizational culture based on the results of regular diagnosis and analysis on organizational culture with two years in cycle from 2006 to 2012 targeting the public officials of KFS are presented as follows: First, The consistent organizational cultural strength has an aspect bringing stability to the organization and merits that clear communication on policy and overall business becomes easier, and agreement or sympathy formation in decision making becomes easier, due to cultural homogeneity. Those merits are implied to work positively in KFS. Second, strength of gap between desirable future culture and current culture could be confirmed, and thus it was understood that measures to cope with such a phenomenon are needed. Third, organization’s head to recognize the need for simultaneously shaping sympathy of all the public officials regarding a direction for organizations to develop through organizational culture. Lastly, this study employs time-series analysis to study the change of organizational culture and confirms the continuous effort for organizational development.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

( Jun Ho Myung ),( Hyun Jeong Seo ),( Soo Jeong Park ),( Bo Young Kim ),( Il Sang Shin ),( Jun Hak Jang ),( Yun Kyung Kim ),( An Soo Jang ) 대한내과학회 2015 The Korean Journal of Internal Medicine Vol.30 No.2

Background/Aims: We sought to increase our understanding of the rhinitis-asthma relationship and improve strategies for the treatment of patients with these diseases. The aim of this study was to identify a connection between upper airway inflammation and lower airway responsiveness. Methods: We counted eosinophils on nasal smears, and performed spirometry, allergic skin tests, and methacholine challenge tests in 308 schoolchildren plus a questionnaire on respiratory symptoms. The methacholine concentration causing a 20% fall in forced expiratory volume in 1 second (PC20 < 25 mg/mL) was used as the threshold of bronchial hyperresponsiveness (BHR). Results: In total, 26% of subjects had positive nasal eosinophils on a smear, and 46.2% of subjects had BHR at < 25 mg/mL methacholine PC20. Nasal symptoms were higher in subjects with than without nasal eosinophils (p = 0.012). Asthma symptoms did not differ between subjects with and without nasal eosinophils. Nasal eosinophils were higher in subjects with atopy than those without (p = 0.006), and there was no difference in PC20 methacholine according to atopy (15.5 ± 1.07 vs. 17.5 ± 0.62; p > 0.05). No difference in BHR was detected when comparing subjects with and without nasal eosinophils. There were significant differences in the PC20 between subjects with greater than 50% nasal eosinophils and without nasal eosinophils (11.01 ± 2.92 mg/mL vs. 17.38 ± 0.61 mg/mL; p < 0.001). Conclusions: These findings demonstrated that nasal eosinophilic inflammation might contribute to lower airway responsiveness in schoolchildren, based on an epidemiological survey.
