The purpose of this study was to investigate the contact angles and wettability of conventional dental stones and improved dental stones and newly developed dental stones on several impression materials. Materials included in this study were several dental stones and newly developed dental stone ; 2 type III stones (Snow Rock, New Diastone), 6 type IV stones(Crystal Rock, Vel Mix, Fuji Rock, Tuff Rock, Resin Rock and newly developed dental stone) and 1 type V stone (Die Keen). Contact angles on the impression materials were measured with contact angle measuring device. Ten specimens for each material, total 180 specimens were made on void entrapment model. The two impression materials (Handae, GC) were used to produce 9 groups of die stone casts form void entrapment model. Voids in the stone casts were counted under a stereoscopic microscope. The grad for the reproduction ability of each materials on the void entrapment model was calculated from the casts by one examiner. From the experiment, the following results were obtained : 1. The newly developed stones showed smallest contact angle. Type III dental stone had larger contact angles than type IV and V stones. Contact angle was much affected by the impression materials. 2. Resin containing die materials such as Tuff Rock and Resin Rock had smallest void number than any other groups. 3. In comparing reproduction parameters, Tuff Rock and Resin Rock presented superior results, while Vel Mix showed lowest reproduction ability.

The objective of the study is to review trends of clothing export in important countries of the world and thus to know the present stage of clothing export in Korea. For the purpose, changes of export amount, competitiveness and product life cycle were analysed in the countries from the 1960's to the 1990's. The results are as following: First, on the aspect of export amount, industrialized countries lost the lead to newly industrializing countries from the 1960's. Developing countries, as China, win the lead. Second, on the competitiveness aspect, industrialized countries lost competitiveness to newly industrializing countries before the 1960's. And newly industrializing countries were outpaced by China in the export competitiveness from the early 1990's. Third, on the aspect of product life cycle, industrialized countries go first through each period of product life cycle, introduction, growth, maturity and decline, and they all, excluding Japan, sustained period of Maturity for a long time. newly industrializing countries and developing countries go orderly through each period of product life cycle after industrialized countries. As to Korea, duration of each period was short. Specially characteristics of decline period appeared partly in the early 1990's. From the results, the theory of product life cycle, helping to explain changes in production and trade in new product lines, estimated to applicable to clothing export. The phenomena, Italy, Hong Kong and America sustain high competitiveness in the world clothing market for a long time, is needed to be studied carefully. The study about strong points in their clothing industries and competitiveness drive program be to influence Korean export policy in the future.

Purpose: This study was to identify predictors of drug dosage calculation error risk in newly graduated nurses. Methods: A total of 115 newly graduated nurses who passed their employment examination, but didn't work for hospital yet, were recruited from a university hospital. The data were analyzed by descriptive statistics, $X^2$-test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression using the SPSS 18.0 program. Results: The mean score of 'drug dosage calculation ability' was $0.81{\pm}0.16$ and the mean score of 'certainty of calculation' was $2.95{\pm}0.60$ out of a 5 point scale. The error risk of drug dosage calculation was positively related to anxiety for drug dosage calculations (r=.388, p<.001), but negatively related to interest and confidence in mathematics (r=-.468, p<.001), confidence related to dosage calculations (r=-.426, p<.001). The main predictors of error risk related drug calculations in newly graduated nurses were identified as interest and confidence in mathematics (${\beta}$=-.468, p<.001). This factor explained about 21.9% of the variance in error risk of drug dosage calculation. Conclusion: The strategies used to decrease the error risk related drug dosage calculation such as improving interest and confidence in mathematics should be developed and implemented.

본고는 홈네트워크 시장에 대한 관심이 증대되고 있는 가운데 이미 건축된 주택(기축시장)을 대상으로 영상전화기(비디오폰)의 판매활성화 방안을 찾는데 목적을 두고 있다. 최근 가전, 네트워크장비, 통신서비스업체들은 새로운 시장을 보며 홈 네트워크에 관심을 가지고 있는데 대부분의 홈네트워크 시장은 신축 고급아파트를 중심으로 활성화되고 있다. 신축시장의 경우 최종고객의 선택권이 없기 때문에 건설 회사를 통해 영업.마케팅을 해야 한다. 그래서 신축시장은 개별적인 수요파악이 어려워 판매활성화를 통해 수익을 창출하는데 에는 한계가 있다고 판단하여 기축시장을 대상으로 향후 수요가 서민주택으로까지 확대될 것에 대비해 기능이 단순하고 가격이 저렴한 보급형 비디오폰 시장개척에 더 많은 노력이 요구된다고 할 수 있다. 이러한 이유로 본고에서는 비디오폰의 개념과 시장동향을 분석하고, 유통경로형태와 A/S 처리시스템을 파악하며 기축시장에 적합한 비디오폰 판매활성화 방안을 모색하는데 그 목적이 있다.

Objectives: The objective of this study was to examine the effect of mentoring function on job satisfaction, organization commitment, and turnover intention in the newly employed dental hygienists. Methods: Two hundred and fourteen dental hygienists in Daegu and Gyeongbuk completed a self-reported questionnaire from January to May 2013. The instrument for the questionnaire consisted of mentoring function, mentoring personality, job satisfaction, organizational commitment, and turnover intention. The data were analyzed by frequency analysis, ANOVA, correlation analysis, and multiple regression analysis. Results: The longer duration of the mentoring for the newly employees strengthened job satisfaction and organization commitment. The mentoring function had a positive effect on job satisfaction and organization commitment, and decreased turnover intention. The higher quality of personality overcome the turnover intention. Conclusions: The mentoring is very important to enhance the job satisfaction and organization commitment in the newly employees. Loner duration of work(${\beta}=.268$, p=0.008) explained higher job satisfaction. Higher quality of personality(${\beta}=0.279$, p<0.001) also had higher job satisfaction. The explanation power of the model was 36.5% and the revised model explanation was 35.6%. The effective mentoring is closely related to job satisfaction and organization commitment and it can reduce turnover intention.

We present a catalog of infrared supernova remnants (SNRs) in the Large Magellanic Cloud (LMC). We have searched the Spitzer archival data for infrared counterparts to all 45 known SNRs in the LMC, and identified 21 which is 47% of the known SNRs. Seven of them are newly detected: SNR 0450-70.9, SNR in N4, N103B, DEM L241, DEM L249, DEM L316A, and DEM L316B. All newly discovered SNRs show emission at several IRAC 3.4, 4.5, 5.8, and 8.0 micron bands and/or MIPS 24 and 70 micron bands. Most SNRs show shell structures. We derive infrared fluxes of these newly detected SNRs. The catalog contains general information of each SNR such as location, age, and SN type together with AKARI and/or Spitzer fluxes. For the entire SNR sample, we examine their infrared colors and the possible correlation of the infrared fluxes with the fluxes at other wavelengths. For the newly detected SNRs except the SNR in N4, we also performed follow-up imaging observations of [Fe II] 1.644 micron line using IRIS2 mounted on the Anglo Australian Telescope. Three out of six SNRs show [Fe II] emission corresponding to their infrared shells. [Fe II] knots are also detected in N103B which show good spatial correlation to infrared emission seen at Spitzer images as well as knotty $H{\alpha}$ emission. We investigate the characteristics and origin of the infrared emission in individual SNRs, and discuss the environmental and evolutionary effects.

The purpose of this study was to investigate the prevalence, primary causes, and management of insomnia newly admitted patients in a university hospital. Subjects consisted of 168 adult patients (95 men and 73 women, 88 medical and 94 surgical patients) newly admitted to Gyeongsang National University Hospital from September 7 through September 27, 1996. Sleep patterns of all subjects in the usual nights before admission(UN), the previous night to admission(PN), the night on admission(ON), and the 5th night after admission(5N) were investigated using the Korean version of the St. Mary's Hospital Sleep Questionaire. In addition, all insomnia patients and their doctors and nurses in charge were interviewed by psychiatric residents. Additionally, their medical records were reviewed. Prevalence of insomnia were 22.6% in the UN, 42.9% in PN, 51.8% in ON, and 43.5% in 5N. The prevalence of insomnia was significantly increased immediately before and after admission. There were no significant differences in the prevalence of insomnia by age and sex. The most ammon primary causes of insomnia were somatic symptoms and psychological factors in PN, somatic symptoms and noise in ON and 5n. Only 17 (10.1%) of insomnia patients took medicstions for insomnia control(analgesics in 15, hypnotics in 2). These results shorred that the prevalence of insomnia was significantly increased on hospitalization due to somatic symptoms, environmental factors, and psychological factors, but nearly none were adequately managed.
