The locus of a camshaft supported on camshaft bearings has been investigated using transient method. Forces applied to camshaft are composed of two components, one is transfer force between cam and tappet, the other is frictional force. These forces have been calculated using lumped mass model and EHL theory. ADI method has been used for numerical analysis of Reynolds equation, and 4th order Runge-Kutta method has been used for transient journal locus analysis. The effects of various load conditions are presented in the form of journal locus. As the result of analysis, it is found that camshaft bearings exist in the hydrodynamic lubrication condition.

This paper gives a review on three illumination issues of face tracking on smart phones: dark scenes, sudden lighting change and backlit effect. First, we propose a fast and robust face tracking method utilizing continuous adaptive mean shift algorithm (CAMSHIFT) and CbCr skin locus. Initially, the skin locus obtained from training video data. After that, a modified CAMSHIFT version based on the skin locus is accordingly provided. Second, we suggest an enhancement method to increase the chance of detecting faces, an important initialization step for face tracking, under dark illumination. The proposed method works comparably with traditional CAMSHIFT or particle filter, and outperforms these methods when dealing with our public video data with the three illumination issues mentioned above.

Based on King's goal attainment theory, this research deals with applying nursing intervention of mutual goal settings to gastrectomy patients. It tests the effects of nursing intervention, according to the patients' health locus of control, suggested as external boundary criteria for the theory by employing a quasi-experimental design which consists of a pretest-posttest non-equivalent control and experimental groups. The subjects of this research were 62 gastrectomy patients hospitalized at Y medical center and the experimental and control groups consisted of 31 subjects. The experimental group received nursing intervention at the mutual goal setting of 5 times from the day before the surgery to the 5th day after the surgery, while the control group received only routine nursing care. Recovery indicators of both groups were measured and compared. Measurement variables included patients' characteristics, health locus of control, forced vital capacity, forced expiratory volume in one second, peak expiratory flow, bowel movement recovery, mobility recovery, level of pain, patients' stress and patients' satisfaction. Data were analyzed using SPSS statistical package and the hypotheses were tested by ANOVA and ANCOVA. Results of the analyses are summarized as follows : 1) Internal health locus of control had higher effects of the nursing intervention of mutual goal setting than external health locus of control on pulmonary ventilatory functions of forced vital capacity, forced expiratory volume in one second, and peak expiratory flow. 2) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the bowel movement recovery between the internal and external health locus of control. 3) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the mobility recovery between the internal and external health locus of control. 4) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of pain between the internal and external health locus of control. 5) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of stress between the internal and external health locus of control. 6) There was a statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of satisfaction with provision of nursing information between the internal and external health locus of control, and there was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of satisfaction with outcome of nursing between the internal and external locus of control. On the basis of the research results, the following are recommended : 1) Repeated research on responses to health locus of control is necessary. 2) Not only the effectiveness of nursing intervention in acute recovery periods, but also the long term effects are to be investigated. 3) The development of instruments is needed to accurately measure mutual goal setting regarding postoperative deep breath, coughing, early ambulation, etc. so that the relationship among the postoperative recovery indicators may be explored. 4) It is required that an instrument be developed to measure perception which facilitates goal attainment in the interactive setting between patients and nurses.

These experiments were carried out to find genetic polymorphisms of Serum protein like Pre-albumin(Pr), Albumin(Al) and Transferrin(Tf), and establish preservation of pure pedigree in Korean Native Goats(KNG). Their serum was collected and examined from the total of 74 KNG that raised in Tang Jin district, Chungnam-province. They were biochemically analysed by polyacrylamide gel(7.5%) electrophoresis(PAGE) in order to estimate the frequencies of genotypes and alleles existing on each trait locus. The results obtained in these experiments were summarized as follows ; 1. In the serum Pre-albumin(Pr) locus, the frequencies of genotypes for hetero AB and homo BB observed were 55.4%, and 44.6%, respectively. While homo AA was not found in the Pr locus. The frequencies of gene in PrA and PrB were 0.723 and 0.277, respectively. Accordingly, the Pr loci were assumed to be controlled by alleles PrA and PrB. 2. The frequencies of genotypes of homo BB and hetero AB detected in Albumin(Al) locus were 75.7% and 24.3%, respectively. However, AA type was not observed in the Al locus. The gene frequencies of AlA an AlB were 0.879 and 0.121, respectively. Also, the Al loci were considered to be controlled by alleles AlA and AlB. 3. The frequencies of genotypes for hetero AD and homo DD found in Transferrin (Al) locus were 79.7% and 20.3%, respectively. Whereas, homotype AA was not detected in this locus. The gene frequencies of TfA and TfD were 0.399 and 0.601, respectively. Therefore, the serum Tf loci were assumed to be controlled by alleles Tfa and Tfd.

Background: Breast cancer is one of the most common cancers among women in the world. Early detection is necessary to improve outcomes and decrease related costs. The aim of this study was to assess the predictive power of health locus of control as a modifying factor in the Health Belief Model (HBM) for prediction of breast self-examination. Materials and Methods: In this cross- sectional study, 400 women selected through the convenience sampling from health centers. Data were collected using part of the Champion's HBM scale (CHBMS), the Health Locus of Control Scale and a self administered questionnaire. For data analysis by SPSS the independent T test, Chi square test, logistic and linear regression modes were appliedl. Results: The results showed that 10.9% of the participants reported performing BSE regularly. Health locus of control did not act as a predictor of BSE as a modifying factor. In this study, perceived self-efficacy was the strongest predictor of BSE performance (Exp (B) =1.863) with direct effect, while awareness had direct and indirect influence. Conclusions: For increasing BSE, improvement of self-efficacy especially in young women and increasing knowledge about cancer is necessary.

The purpose of this study was to examine effect of locus of control and self-efficacy on stress of selected dental hygiene students. This study provides basic data to develop a method to reduce stress. The students of A women's college in Kyungi province majoring in dental hygiene were asked to answer the locus of control scale, self-efficacy scale, and stress level. As a result, this study concluded the following findings: 1. Locus of control scale was 8.77 and it meant the students used internal control. Self-efficacy scale was beyond median. In stress level category, mean of stress was 2.32, stress with friends was 2.05, stress with money was 2.33, stress with course in life was 2.29, stress with family members was 2.24, stress with study was 2.95. 2. Stress had negative relations with locus of control and self-efficacy. There was a positive relation between locus of control and self-efficacy. 3. Effect of self-efficacy on stress was significantly negative but effect of locus of control on stress was insignificant. In subscale, effect of self-efficacy and locus of control on stress with study was insignificant. 4. Indirect effect of locus of control on stress was statistically significant. The students with internal locus of control showed high self-efficacy and the students with high self-efficacy showed low stress level. In conclusion, educators should make an effort to reduce stress of students and understand the factors related to stress.

'Control of Locus of Reinforcement(LOCR)' is considered one of the main important factors on responsible environmental behaviors(REB). It is defined as 'an individual's perception of his or her ability to bring about change through his or her behavior'. This phychological construct is divided in two, external locus and internal locus. Internal locus of reinforcement is important as predictor for REB. Lately, 'The Environmental Action Internal Control Index:EAICI' was developed. It is a valid and reliable instrument to measure relationships of two variables. The purposes of this study were to analyse the orientation of LOCR in high school students and relations with LOCR to REB. By the results, EAICI scores of total students, males, females are 99.83, 95.10, 104.56, respectively. LOCR of females was stronger and more internal than one of males. The item scores for behaviors that reduce the amount of household trash by reusing and recycling and convince someone to do this are 4.31, 4.05, respectively. The item scores for behaviors that convince someone to sign a petition regarding on environmental issues, convince someone to reuse envelopes by putting a label over the old address and convince someone to keep car tires properly inflated are 3.09, 3.09, 3.04, respectively. It shows that EAICI scores are dependent upon the degree of the chances and experiences to meet the various environmental events.

Simple sequence repeats (SSR) are widely dispersed throughout eukaryotic genomes, highly polymorphic, and easily typed using polymerase chain reaction (PCR). The objective of this study was to determine the polymorphism of different Chlamydomonas reinhartdtii strains and to determine the mode of inheritance of the SSR locus in Chlamydomonas. A genomic DNA library of C. reinhardtii was constructed and screened with a radiolabeled $(AC)_{11}$ probe for the selection of (CA/GT)n repeat clone. Selected clone was seqeuenced, and PCR primer set flanking (CA/GT)n sequence was constructed. PCR was used to specifically amplify the SSR locus from multiple isolates of C. reinhardtii. The locus was polymorphic in some of the C. reinhardtii isolates. However, the locus was amplified only 4 of 6 isolates of C. reinhardtii, not in other 2 isolates of C. reinhardtii, suggesting that this locus is not extensively conserved. A simple Mendelian inheritance pattern was found, which showed 2:2 segregation in the tetrads resulting from a cross between C. reinhardtii and C. smithii. Our results suggest that this simple sequence repeat DNA polymorphism will be useful for identity testing, population studies, linkage analysis, and genome mapping in Chlamydomonas.

We describe tests for detecting and locating quantitative traits loci (QTL) for traits in Hanwoo. Lod scores and a permutation test have been described. From results of a permutation test to detect QTL, we select major DNA markers of BMS941 microsatellite locus in Hanwoo chromosome 17 for further analysis. K-means clustering analysis applied to four traits and eight DNA markers in BMS941 resulted in three cluster groups. We conclude that the major DNA markers of BMS941 microsatellite locus in Hanwoo chromosome 17 are markers 80bp, 85bp 90bp and 105bp.
