  • 정상잠이 3령의 성식기에 이르렀을때(춘잠기 소잠후약 9일 20시간 경과한 무렵) 불면잠으로 인정되는 것과 같은 잠박에서 정상잠을 재료로 하여 이를 고정하였고 또한 4령의 성식기에 1~2령기의 발육정도 밖에 되지 않은 왜소잠을 수집하여 고정하고 이와 동시에 이때의 정상잠도 고정하였다. 불면잠과 정상잠을 형태학적으로 비교하고 그 조직검사에서 얻은 조사내용을 요약하여 보면 다음과 같다. 1. 정상잠이 3령의 성식기에 이르렀음에도 불면잠으로 인정되는 누에는 마치 소잠후 2일이 경과한 정도의 누에의 크기에 불과하였으며 4령의 성식기에 관찰한 불면잠도 이와 대동소리라하였다. 2. 태피선은 타원형의 편평한 낭상체로서 그 크기는 흉부에 위치하는 것이 작고 복부의 것이 일반적으로 큰 경향을 나타냈다. 3. 흉부에 있는 태피선은 흉지의 기부에 있는 것이 배맥관을 끼고 있는 태피선보다 큰것으로 종내에는 보고되었지만 본실험결과에 었어서는 일정한 경향이 없었다. 4. 정상잠이 3령의 성식기에 이르렀을 때의 태피선의 크기는 전흉에 있는 것이 최소로서 151.3$\mu$(major axis)~94.5$\mu$(minor axis)였고 최대로서는 복부제7절의 것이 568.6$\mu$~495.$\mu$였으며 이때에 불면잠으로 인정되는 것은 최소로서 전흉에 있는 태피선이 57.5~51.3$\mu$이였으며 최대로서는 복부제5절의 것이 91.5~75.5$\mu$으였다(표 1. 참조) 5. 정상잠이 4령의 성식기에 이르렀을 때 정상잠과 왜소잠의 태피선의 크기를 비교해 본 바에 의하면 정상잠에 있어서는 전흉의 것이 최소로서 252.2~131.6$\mu$이였고 복부제7절의 것이 최대로서 691.5~493.4$\mu$이였으며 왜소잠에 있어서는 후흉의 것이 최소로서 71.4~61.5$\mu$이였고 복부제8절의 것이 최대로서 94.6~71.5$\mu$이였다(표 2. 참조) 6. 불면잠에 있어서의 태피선의 형태는 그 공포형태피선이 정상잠의 것과 크게 차이가 있어 공흉의 크기가 정상잠의 것에 비하여 몇배에 달하였다. 7. 불면잠과 정상잠과의 분필세포의 구조에는 큰 차이가 없지만 불면잠의 과립형태피선은 정상잠에 비하여 소형이 었다.

  • Purpose: The purpose of this study was to investigate the effect of nursing education using a CD ROM on the anxiety and knowledge of the patients having minor surgery. Method: Forty patients hospitalized in K hospital in Seoul from April to August 2002 participated in this study. In the experimental group, twenty patients received nursing education on the operational procedures and post-operational care. The control group, received conventional nursing care only. Anxiety experienced by patients was measured by Spielberger's State-Trait Anxiety Inventory, and knowledge was measured by an instrument developed by Rahe et al. The data were analyzed by SPSS statistical program. Result: There were no significant differences in anxiety level between two groups. However, subjects in the experimental group were found to have significantly higher postoperative knowledge levels than those in the control group, and were very satisfied with the CD ROM program. Conclusion: The nursing education program using CD ROM before minor surgery proved to be an effective nursing intervention to increase knowledge of patients and contribute to their self care after discharge. To decrease anxiety of the surgery, the nursing education program should be combined with supprortive emotional nursing intervention, such as touch, and massage.

  • The present study was designed to find out the construction conditions of tight skirt for sale in relation to its brand, target age and length. The 15 tight skirts each from 3 brand groups(designer character, national and minor brand) of 2 target age groups(youth and middle age) and the 15 tight skirts each from 3 skirt length groups(mini, natural line and maxi) of only the minor brand-a total of the 120 tight skirts on the market-were measured. The data were analyzed with use of SAS package. The statistics were based on frequency, percentage, average, standard deviation, one-way ANOVA, two-way ANOVA, Pearson's correlation and linear regression analysis. The main results were as follows. 1. There were significant differences in the construction conditions of tight skirt according to its brand and target age. There was a significant difference particurarly in the difference between hip girth and hem girth according to brand target age. The difference between hip girth and hem girth of designer's character brand skirt was larger than that of national brand & minor brand skirt, and that of skirt targeting the youth was larger than that of skirt targeting the middle aged. 2. There were significant difference particurarly in the differences in the construction conditions of tight skirt according to its length. There was a significant difference particurarly in the difference between hip girth and he girth according to skirt length, and that of maxi skirt was larger than that of mini & natural line skirt. There was a good correlation between skirt length and slit length and between skirt length and skirt length above the slit. The longer the skirt length was, the longer the slit length and the skirt length above the slit were.

  • The pesticide and carcinogen ethylene dibromide(EDB) is metabolized both by cytosolic GSH S-transferase and by microsomal mixed function oxygenase. Cytochrome P-450 IIE1 appears to be major enzyme to metabolize EDB.EDB is activated to a mutagen by enzymatic conjugation with glutathione (GSH). Such activation is an exception to the general mode of detoxification via GSH S-transferase action. The primary DNA adduct (>95) is S-[2-(N7-guanyl)ethyl] GSH and a minor adduct is S-[2-(N7-guanyl)ethyl]cysteine, which is excreted in the urine and may serve as a biomarker of damage.

  • Segmental retaining wall market in Korea has been growing dramatically since late 1990s in both engineered and non-engineered applications. Despite the inherent conservatism in the current design approaches, numerous major and minor structural problems have been reported during and after construction, covering a range of minor structural damage to total collapse. Much still needs to be investigated to fill the gap between the theory and the practice. This paper reviews several design issues with regard to the segmental retaining walls such as the selection of shear strength parameters for backfill soil, local stability, and tiered wall construction. In addition, the effects of shear strength parameters and the fundamental behavior of tiered SRWs are examined based on the results of finite element analysis. Implications of the findings from this study to current design practices were discussed in detail.

  • Necrotizing sialometaplasia (NS) which mimics malignancy both clinically and histopathologically is an uncommon benign, self-limiting inflammatory disease of the mucus-secreting minor salivary glands. The lesion is believed to be the result of vascular ischemia that may be initiated by trauma. Till date, the diagnosis of NS remains a challenge. This report demonstrates a case of NS in a 73-year-old male patient who presented with an ulcerative lesion in his palate. He had a history of local trauma and was long-term user of salbutamol inhaler. An incisional biopsy was carried out and the diagnosis was established through history, clinical examination, histopathology using Hematoxylin and Eosin stain. The patient was given symptomatic treatment and the lesion healed in about 7 weeks.

  • Recently developed technique of measuring minor species concentration by using the modulation dip in broadband CARS has been applied to the flame structure study of methane/air premixed flames in a counterflow. This method used the modulation dip from the cold band CO Q-branch resonant signal superimposed on the nonresonant background. The measured CO concentration profile in a symmetric and unsymmetric methane/air premixed flames together with the velocity and temperature by using LDV and CARS have been compared with the numerical results adopting detailed chemistry modeling. The results show that there is a satisfactory agreement between the experimental data and numerical results for velocities, temperatures and CO concentrations. And the modulation dip technique of measuring minor species, such as CO is a viable tool for a quantitative measurement in a flame.

  • The purpose of this paper is to obtain design method of air-distribution system. Air-distribution system is composed of blower, duct, diffusers and measuring equipment. The air-flow rate from each diffuser is not equal. The air-flow rate is calculated with the combined equations which are Bernoulli's equation, continuity equation and minor loss equations. Inlet condition and outlet condition are adapted in each duct system. Then square difference between function of maximum air-flow rate and minimum air-flow rate is used as an object function. Area of diffuser and velocity are established as constraints. To minimize the object function, the optimization method is used. After optimization the design variables are selected under satisfaction of constraints. The air-distribution system is calculated again with the result of optimized design variable. It is shown that the air-distribution system has the equal air-flow rate from diffusers.

  • Organizations worldwide have implemented quality management system, ISO 9001:2000 and environmental management system, ISO 14001:2004. Researches have been conducted regarding occupational health and safety management system, integration of these management systems, and extension to corporate social responsibility and sustain ability management system, ISO 26000. This paper examines quality and environment management systems for machinery and metal companies using audit results. We perform statistical tests to see if there are any significant differences of minor nonconformities for requirements of ISO 9001:2000 and ISO 14001:2004 based on implementation motive, operating periods, and organization's size. We also present causes and reasons for statistical differences and minor nonconformities to use as references for implementing efficiently quality management system and environment management system.

  • The current study uses longitudinal data, which show secondary school students' responses in a biennial data of surveys from England (n=4,326/boys=2,313;girls=2,413) and Scotland (n=3,528/boys=1,744;girls=1,784), to describe the association between availability of cigarette sales to minor, prosmoking attitudes of family members and drinking/drug use and smoking behaviours amongst adolescents. The findings provided strong evidence suggesting that availability of cigarette sales to minor, lack of familial interest on the child's smoking and other substance use were positively associated with the increased level of smoking behaviour in youth. Girls and boys also differed the likelihood of smoking and being a regular smoker. Boys were found to be more likely than girls to be smoking and to be a regular smoker. The implications of promising prevention programmes for preadolescents and areas for future research are presented
