      • 無勞動 無賃金이 勞使紛糾에 미치는 影響

        魯淳圭 동국대학교 대학원 1991 東院論集 Vol.4 No.-

        The object of this study is that the principle of no work no pay has an effect labor & management conflicts. Recently the conflicts between labor & management are increasing gradually, specially since 6.29 declaration(1987), the rate of its increase was very high. The concept of no work no pay is that case no work is generously in strike and sabotage. The principle of no work no pay is first derived from work contract of between labors & management, second result from the equity of law. But those who oppse the principle of no work no pay insist that the principle is not resonable because payment is living expense, and because of security of the right, that is to say, the union law. In case of foreign nations, for example, Japanese, American and European, they observe the principle of no work no pay. In search of our country, employer and manager give their approval to the principle (the approval ratio of 55.1%). But the representatives of union raise an objection (the opposition ratio of 82.5%). Now a day, the firms of compliance for the no work no pay increased , for instance, 6% in 1988, 34.2% in 1989, 83.9% in 1990. And the dispute of labor and management is decreased 1,879 in 1988, 1,585 in 1989, 347 in 1990. Therefore, in this study, we can find that the more the principle of no work no pay is observe, the less the conflicts of employer & employees. Hear after the labors and management observe the principle no work no pay, but union must save up the fund union, when they strike, they use the fund, don't depend on their employer.

      • Agrobacterium tumefaciens의 Ti plasmid 재조합에 관한 연구

        주충노,이희봉,김영명 연세대학교 자연과학연구소 1987 學術論文集 Vol.19 No.-

        Crown gall의 병원체로 알려진 Agrobacterium tumefaciens가 함유하고 있는 Tumor inducing(Ti) plasmid가 식물 hormone과 opine의 합성원인이라는 것이 밝혀지고 식물 세포의 crown gall에는 Ti plasmid가 존재하며 Ti plasmid의 일부가 식물세포의 핵 genome에 삽입되어 형질 변화가 일어남이 보고 되었고 Ti plasmid의 식물체로의 gene도입 vector로서의 연구가 최근 활발히 진행되고 있으며 현재 PLGV vector와 PMON vector 등이 개발되고 있으나 조작이 복잡하고 아직은 초보적 단계인 것으로 알려져 있다. 본 연구에서는 원하는 식물 gene을 식물체에 도입하는 유용한 vector개발의 초보단계로서 Ti plasmid의 T-DNA의 일부인 nos gene을 분리하여 pBR322와의 재조합을 기도한 것이다. pBR 322를 포함하는 E. coli로 부터 Horwitz(1979)의 방법으로 pBR 322를 분리하였고 A. tumefaciens C58에서 Kado(1979)의 방법으로 Ti plasmid를 분리한 후 Ti plasmid 내의 nos gene을 분리하였다. 분리된 pBR 322를 Hind Ⅲ로 절단한 후 CIP로 처리하고 T_4 DNA ligase를 이용하여 Hind Ⅲ로 처리한 nos gene fragment와 재조합하였다. 이와같이 하여 얻은 recombinant DNA로 인한 E. coli HB101의 형질 변화를 Mandel과 Higa의 방법에 따라 조사한 결과 pBR 322의 tetracyclin gene 사이에 nos gene이 삽입된 것으로 확인되었다. 즉 ampicillin 배지에서는 92개의 colony가 형성되었는데 그중 59개는 tetracyclin 배지에서 colony를 형성하지 못하였다. 이러한 tetracyclin 감수성이면서 ampicillin 저항성인 colony를 배양하여 얻은 recombinant plasmid를 전기이동법으로 분리한 결과 예상대로 크기가 7.5kb 정도였고 Hind Ⅲ로 절단하였을 때 2개의 band가 확인되었다. 본 연구에서 얻은 nos gene-pBR 322 hybrid plasmid는 원하는 식물 gene을 이것에 삽입하여 A. tumefaciens 내에서 homologous recombination을 행한 후 식물체에 감염시켜 원하는 gene의 발현여부를 검출하는데 이용될 것으로 기대된다. It is mow realized that the tumor-inducing(Ti) plasmid in Agrobacterium tumefaciens is responsible for the induction of crown gall tumors in dicotyledonous plants and it has been demonstrated that a segment of the Ti plasmid, so called T-DNA, is stably integrated into and expressed in the genome of transformed plant cells. Recently, the use of A. tumefaciens Ti plasmid as a vector to introduce a foreign gene has been intensively studied and several vectors such as PLGV vector and PMON vector has been reported. However, their practical use is still at a primitive stage. It was attempted in the present study, therefore, to conduct the recombination of nos gene of T-DNA from A. tumefaciens Ti plasmid and E. coli pBR 322 as a vector it introduce foreign plant gene into dicotyledon plant cells. pBR 322 was isolated from E. coli containing pBR 322 accdrding to Horowitz(1979) and nos gene of T-DNA in Ti plasmid from A. tumefaciens C58 was obtained according to Kado(1979). The isolated pBR 322 was cut using Hind Ⅲ followed by the addition of CIP·pBR 322 fragments and Hind Ⅲ treated nos gene fragments were than recombined using T_4 DNA ligase and the E. coli cells were then transformed by recombinant DNA according to Mandel and Higa(1970). It was confirmed that nos gene was inserted into tetracyclin gene of pBR 322 by the finding that when the transformed cells were incubated in the ampicillin medium, 92 colonies were formed, in which 59 were tetracyclin sensitive. The above tetracyclin sensitive but ampicillin resistant cells were then cultured and the recombinant pBR-nos gene was isolated and subjected to electrophoresis. It was found that size of the recombinant DNA was approximately 7.5 Kb as expected and two bands were appeared on electrophoretogram when the recombinant DNA was treated with Hind Ⅲ. It might be possible to insert the foreign plant genes to the pBR-nos gene hybrid plasmid obtained in the present study and the resultant DNA could be then homolgously recombined with Ti plasmid of A. tumefaciens and the final recombined Ti plasmid could be used for the introduction of the foreign plant genes into dicotyledon plant cells.

        Introduction : No drain technique during parotidectomy had been introduced to reduce postoperative morbidity and to minimize hospital stay in a few previous publications. Since the authors have applied this technique in select patients for several years, we wanted to evaluate the feasibility and usefulness of no drain parotidectomy. Material & Methods : We retrospectively reviewed the medical records of 96 patients who underwent superficial or total parotidectomy by one surgeon from May 2005 to July 2012. The decision on drain insertion was made by the operator at the end of the surgery. The patients were categorized as drain insertion group and no drain group. Results : The patients who have smaller tumors and benign lesions were more frequently chosen into no drain group. Hospital stay was shorter in no drain group than in drain insertion group. Although no drain group showed increased number of acute complications such as seroma and hematoma, the complications were mild and could be controlled easily at the outpatient clinic. Conclusion : No drain technique during parotidectomy could be done relatively safely in select patients and it could reduce hospital stay.

        본 연구는 노사협의회를 중심으로 비노조 근로자대표조직의 경영성과 효과를 실증적으로 분석하는데 기본 목적을 두고 실시되었다. Rreeman-Lazear(1997)의 작업장평의회 성과모형을 기초로 하여 도출된 본 연구의 가설들은 다음과 같다. ⑴ 비노조 근로자대표조직은 노동조합 및 무근로자대표성에 비해 노동생산성을 높일 것이다. ⑵ 비노조 근로자대표조직은 노동조합에 비해 수익성을 높일 것이다. 그리고 탐색과제로서 ⑶ 비노조 근로자대표조직이 무근로자대표성에 비해 수익성을 높일 것인지 여부를 설정하였다. 본 연구는 비노조 근로자대표조직으로서 노사협의회를 유사노동조합형, 협의형, 의견청취형 등으로 구분하고 노동조합 및 형식적 노사협의회(또는 무노사협의회)를 비교 대상 범주로 하여 희귀분석을 실시하였다. 분석결과는 비노조 근로자대표 조직의 여러 유형들이 노동조합이나 무근로자대표조직에 비해 노동생산성을 높이지 않고 있음을 보이고 있다. 그러나 근로자대표조직의 유형들이 노동조합에 비해서는 수익성을 높이고 있어서 본 연구의 분석결과는 부분적으로만 Freeman-Lazear(1997)의 작업장평의회 모형의 예측을 지지하고 있다. 그리고 탐색과제와 관련해서, 비노조 근로자대표성은 무근로자대표성보다 수익성을 높이지 않는 것으로 나타나고 있다. 마지막으로 분석결과의 함의와 한계가 논의되었다. This study examines the firm performance effects of non-union employee representation with a focus on joint consultation committees(JCCs). Th hypotheses that we draw, based on works council models of Freeman-Lazear(1997) are as follows:(1) Non-union employee representations have a positive effect on labor productivity, as compared to trade union and no employee representation, and (2) non-union employee representations have a positive effect on profit, as compared to trade union. In addition, we explore how non-union employee representations affect profit, as compared to no employee representation. This study classifies JCCs as the union-like type, the consultative type and the hearing type, and estimates the regression models of sales per capita and operating incomes per capita on the types against trade union and no employee representations. The results of this study indicate that any type of JCCs does not have a significantly positive effect on sales per capita as compared to either trade union or no employee representation. On the other hand, most types of JCCs have significantly positive effects on operating incomes as compared to trade union. And also all the types of JCCs have a lower effect on operating incomes, as compared to no employee representation. Finally the implications and limitations of this study are discussed.

        Epidemiologic studies of air pollution need accurate exposure assessments at unmonitored locations. A land use regression (LUR) model has been used successfully for predicting traffic-related pollutants, although its application has been limited to Europe, North America, and a few Asian region. Therefore, we modeled traffic-related pollutants by LUR then examined whether LUR models could be constructed using a regulatory monitoring network in Metropolitan area in Korea. We used the annual-mean nitrogen dioxide (NO2) in 2010 in the study area. Geographic variables that are considered to predict traffic-related pollutants were classified into four groups: road type, traffic intensity, land use, and elevation. Using geographical variables, we then constructed a model to predict the monitored levels of NO2. The mean concentration of NO2 was 30.71 ppb (standard deviation of 5.95) respectively. The final regression model for the NO2 concentration included five independent variables. The LUR models resulted in R<SUP>2</SUP> of 0.59. The mean concentration of NO2 of elementary schools was 34.04 ppb (standard deviation of 5.22) respectively. The present study showed that even if we used regulatory monitoring air quality data, we could estimate NO2 moderately well. These analyses confirm the validity of land use regression modeling to assign exposures in epidemiological studies, and these models may be useful tools for assessing health effects of long-term exposure to traffic related pollution.

      • Dye Binding Capacity of Commercial Chitin Products

        No,,Hong,Kyoon,Cho,,Young,In,Meyers,,Samuel,P. 대구효성가톨릭대학교 식품과학연구소 1996 식품과학지 Vol.8 No.-

        Dye binding capacity of different commercial chitins was investigated with two commercial chitin products and two dyes (FD&C Red No.3 and Yellow No.5). Dye binding capacity of chitin increased with increasing dye concentrations and was dependent on the chitin products and the specific dyes used. A slight decrease in dye binding capacity was noted with reduction in chitin particle sizes. Within a pH range of 3-9, dye binding capacity was relatively stable. After 24 h of settling, no dye was released from dyed chitin at pH 2 and 3. Above this range, release of dye increased with pH, up to 1.1 and 5.8% of bound red and yellow dye, respectively, at pH 9. Dye release was less noticeable in 1 h of settling.

        N-nitrosamines are a class of carcinogenic chemicals that can pose significant hazards to the human life. Ultraviolet (UV) light irradiation is considered as one of the effective methods to reduce N-nitrosamines in the aqueous phase. This study aimed to investigate the pH influence on UV photodegradation of N-nitrosamines (i.e., N-nitrosodibutylamine (NDBA) and N-nitrosopyrrolidine (NPYR)) closely related to water treatment. Photodegradation rate constants of NDBA and NPYR remained between 3.26×10-2 L/W-min to 5.08×10-3 L/W-min and 1.14×10-2 L/W-min to 2.80×10-3 L/W-min at pH2-10, respectively. This study also focused on the formation of oxidized products (i.e., primarily NO2- and NO3-). Under slightly acidic and eutral conditions, NO2- formation was more prevalent than NO3- formation, while under strong acidic conditions, NO3- was more prevalent. There was no significant change in total organic carbon (TOC) and total nitrogen (TN), suggesting negligible loss of N-nitrosamines and degradation products from the system. NDBA was easily photodegraded than NPYR. This study also demonstrated that a lower pH is a favorable condition for photolytic degradation of N-nitrosamines in water.

        The effects of nitric oxide (NO) on inhibitory neurotransmitter receptors and some types of inhibitory receptors in dissociated rod bipolar cell (RBC) were investigated. In the whole cell voltage-clamping mode, the gamma-aminobutyric acid (GABA) activated current showed both sustained and transient components. GABA activated transient current was fully blocked by bicuculine, a GABA<SUB>A</SUB> receptor antagonist. The cis-4-aminocrotonic acid (CACA), a GABA<SUB>C</SUB> receptor agonist, evoked the sustained current that was not blocked by bicuculline (BIC). Glycine activated the transient current. These results indicate that the RBCs possess GABA<SUB>A</SUB>, GABA<SUB>C</SUB>, and glycine inhibitory receptors. Sodium nitroprusside (SNP), a NO analogue, reduced the currents activated by GABA<SUB>A</SUB> receptor only, however, did not reduce the currents activated by either GABA<SUB>C</SUB> or glycine receptors. This study signifies further that only NO depresses the fast inhibitory response activated by GABA<SUB>A</SUB> receptor in RBC. We, therefore, postulate that NO might depress the light-on/off transient inhibitory responses in RBCs in the rat retina.

        노은미 ( No Eun-mi ) 한국보건복지융합학회(구 한국노인의료복지학회) 2019 노인의료복지연구 Vol.11 No.1

        This study intends to investigate the effect of subjective oral health status on the social efficacy of the elderly. It was conducted from September 1, 2019 to September 30, 2019 for elderly people over 60 years old in Ulsan, Busan, and Daegu. The final analysis of 329 data was conducted. Social efficacy was higher when males were 70-74 years old and high school graduates, and the social efficacy according to subjective oral health status felt good oral health condition, no food manipulation disorder, no toothache, no periodontal problem, And there was no bad breath, and there was a significant difference (p<0.001). Factors affecting social efficacy were most affected by jaw joint disorder (β= -0.152), oral health status (β= -0.114), bad breath (β= -0.112), and toothache (β= -0.093). , Food manipulation disorder (β= -0.085), dry mouth (β= 0.029), periodontal problem (β= 0.024). In other words, the subjective oral health status of the elderly affects the social efficacy, which is an important factor for the successful aging of the elderly.
