The mean residual function is the expected remaining life of an item at age x. The problem of trend change in the mean residual life is great interest in the reliability and survival analysis. In this paper, we develop a family of test statistics for testing whether or not the mean residual life changes its trend. The asymptotic normality of the test statistics is established. Monte Carlo simulations are conducted to study the performance of our test statistics.

This study is devoted to suggesting the norm of detection abnormal users who are inferior to the other users in the recommender system compared with estimation accuracy. To select the abnormal users, we propose the pre-filtering method by using the preference ratings to the item rated by users. In this study, the experimental result shows the possibility of detecting the abnormal users before the process of preference estimation through the prediction algorithm. And It will be possible to improve the performance of the recommender system by using this detecting norm.

In this study, we questioned what assessment types and scoring methods of science performance assessment(SPA) were being used in middle and high school, and how much these SPA scores were reliable(generalizable). To answer these questions, SPA data obtained from the seven schools were classified according to assessment type and scoring method. Based upon this classification, we analyzed the reliability by applying generalizability theory. The result, from the classification of assessment type and scoring method, showed that SPA types of the seven schools were divided into two types: paper-pencil type and task type. Paper-pencil type included answer(content)-restricted essay-type test solely. Task type has two parts: process and outcome assessment. As the results of analyzing scoring methods of the seven schools, there were two cases in the way of scoring methods: one case is scoring all essay-type items and performance tasks by one teacher, the other is scoring assigned performance tasks by two teachers. But the case of scoring assigned essay-type items or the case of cross scoring by two or more teachers were not found. The findings of the reliability analysis are as follows: (1) Effect of essay-type item to SPA score was larger than that of performance task. (2) There was remarkable difference among the seven schools' interaction effect of person and rater in scoring performance tasks. (3) Most of generalizability(reliability) coefficients of SPA for the seven schools were smaller than the acceptable generalizability coefficient(0.80). Therefore, the population of statistical parameters such as number of item, task and rater, should be increased for approaching the acceptable generalizability level.

This study was done to investigate how importantly midwives thought of Lamaze Method of Childbirth, how satisfactorily they performed their Lamaze Method of Childbirth and what inhibited their activities from being performed if not done satisfactorily. The subjects of this study were 76midwives at midwifery in Pusan, Deagu, Kyungnam and Kyungbok. Data were collected by using questionaire from Sep. 1 to Sep.30, 1991. The measurement tools was maded by the researcher based on Kim's scale for prenatal nursing activities. The statistical analysis was done with based statistical values likes frequencies, means, standard deviations and advanced methods such as Pearson's correlation coefficient, 1-test, F-test, F-test by using SPSS package program. The results of this study can be summarized as follows ; 1. The results of Investigating perception according to importance degree and performance degree of Lamaze Method of Childbring showed that midwives were slightly below both perception according to importance(2.17) and performance(2.16) of Lamaze Method of Childbirth 2. Inhibiting factors of Lamaze Method of Childbirth were abscence of husband(3.08), lack of teaching room(2.71), and lack of books or literature of Lamaze Method (2.58). 3. There appears to be a positive relation between perception according to importance degree and performance degree of Lamaze Method of Childbirth (r=0.69, P<0.01). There appears to be a negative relation between perception according to importance degree and inhibit factors of performance (r=-0.38, P<0.01). There appears to be a negative relation between performance and inhibit factors of performance (r=-0.22. P<0.01). 4. The item of highest perception defree in prenatal education is 1st, Consultation about sexual life (2.53), End, illustration of the importance of a bath and perinal cleanliness and Avoidance of excessive respiration method and also its comfortable application during uterine contractility(2.45). The item of lowest perception degree is about pregnant symptom sign and predicted date of birth (E.D.C.). On the other hand, The item of highest performance degree is education about nurtrition during pregnacy. 2nd, Illustration of the Importance of a bath and perineal cleanness(2.45). The lowest one is leaching the pregnant woman and her family about the role of husband and her family and also teaching the couple to learn exercise and respiration method (1.84). Though importance perception degree and performance degree is low. Midwives who wert subject in this research shoves that they perform general items concerning prenatal education well. 5. In the relationship between perception according to importance degree of Lamaze Method of Childbirth and the general characteristics of subjects, the differences in mean number of visiting pregnacies for 1 month. 6. In the relationship between performance degree of Lamaze Method of Childbirth and the general characteristics of subjects, the differences in age, marriage, and mean number of visiting pregnancies for 1 month. With the above information we see the importance of midwife prenatal care education and high correlation between performance degree and perception degree. When Lamaze prenatal education is well performed the number of pregnant woman who have follow-up, check-ups increase. Therefore in this research we can validity that there is a relation between Lamaze prenatal education and patient follow-up. This research showes in a situation where if one does not maximally perform a prenatal education there is a possibility that the popular use of midwife activities may encounter obstacles so the education to save new knowledge and training for prenatal education is needed as a function of Lamaze prenatal education, when a special Lamaze education is well performed for the pregnant woman, who follows-up at amidwife clinic. With the above conclusion we can suggest : 1. Continued research which minimized obstacles to Lamaze prenatal education is needed. 2. The official method of midwives is necessary.

This study investigated the current status of foodservice management and the importance and performance of foodservice management according to the level of knowledge of workers. A survey was conducted between February 2015 and March 2015 for 329 foodservice workers at Community Child Centers in Chungbuk Area. Of these respondents, the majority (78.4%) of them were females. Most of them were in their 40s (40.4%) or 50s (33.4%). If the respondent's correct answer rate of knowledge was 0~50% or 51~100%, the respondent was classified into a 'Low Group (LG, n=175)' or a 'High Group (HG, n=154)'. Among a total of 14 foodservice management questions, 6 items (personal hygiene: 1 item; food material: 2 items; and food processing: 3 items) had relatively higher performance scores for workers in HG than for workers in LG. As a result of Importance-Performance analysis, 'Use different knives and cutting boards for fish, meat, and vegetables' was a variable of high importance but low performance. It was found that improvement was most urgently needed. Results of this study can be used to derive important items for improving foodservice management and policy development for foodservice workers at Community Child Centers.

Background: The present study was performed to examine the factors required for active engagement of participants in exercise therapy by surveying the frequency of participation, fidelity of performance, and supporting materials and rewards provided to encourage participation in the study. Design: Cross-sectional study. Methods: The survey was conducted in a population of 103 participants in at least one exercise treatment study. A 12-item questionnaire was designed to determine the frequency of exercise participation and fidelity of participant performance. Results: The results were subjected to frequency analysis and Pearson's correlation analysis. The subjects were less likely to exercise with the therapist and less likely to exercise at home. In addition, the provision of supplementary materials, to be considered when exercising at home, was insufficient. A strong positive correlation was found between the frequency of exercise in the presence of a therapist and the fidelity of participant performance (r=0.812, p=0.001), whereas a weak negative correlation was found between the frequency of unperformed exercises and the fidelity of participant performance (r=-0.523, p=0.023). Conclusion: The results of the present study suggested that it is necessary to increase the number of times that exercises are performed with the therapist to motivate increased frequency of exercise participation and fidelity of participant performance. In addition, appropriate rewards and periodic management are required.

Objective : There are four possible explanations for the sexual dysfunction of schizophrenics. The first is the possibility of a real structural aspect. The second possibility is that sexual function changes secondary to the illness. The third possibility is that there are medical and sociocultural barriers to sexual expression for chronic schizophrenics. The fourth possibility is that sexual dysfunction due to antipsychotic medication. However, we didn't know the precise cause of sexual dysfunction in schizophrenics. Therefore, the purpose of this study was to explore the mechanism of illness itself and antipsychotics on sexual dysfunction in male schizophrenics. Methods : The serum prolactin(PRL), testosterone(TST), and the plasma serotonin(5-HT) concentrations were measured by radioimmunoassay and high performance liquid chromatography method for 100 healthy male schizophrenics according to the DSM-IV. Concomitantly, the severity of psychotic symptoms using Clinical Global Impression(CGI), Brief Psychiatric Rating Scale(BPRS), Positive and Negative Syndrome Scale(PANSS), and the severity of side effects for antipsychotics using Extrapyramidal Side Effects Scale(EPSE), Anticholinergic Side Effects Scale(ACSE), the cognitive function using PANSS-Cognitive Function(PANSS-CF), Mini Mental State Exam-Korean(MMSE-K), and the sexual dysfunction using Sexual Functioning Questionnaire(SFQ), Questionnaire for Sexual Dysfunction in Men were assessed. The PRL, TST, and 5-HT levels of 50 healthy male controls who had no medical, neurological, and psychiatric illnesses were evaluated. The sexual function using SFQ(items FGa, FNa) were also assessed. Furthermore, the correlation with age, education, religion, economic status, age at onset, duration of illnesses, duration of admission, levels of PRL, TST, 5-HT, antipsychotic dosages, potency, benztropine, total duration of medication, EPSE, ACSE, CGI, BPRS, PANSS, PANSS-CF, MMSE-K and sexual dysfunctions were identified in male schizophrenics. Results : 1) The frequencies of sexual dysfunctions for schizophrenics(80%) were significantly(p<0.001) higher than those for controls(42%). The sexual dysfunctions according to sexual response cycle were 'low sexual desire' 76%, 'impairment of achieving erection' 75%, 'impairment of maintaining erection' 75%, 'impairment of obtaining orgasm' 32%, 'impairment in the quality of orgasm' 61%, 'impairment in quantity of ejaculate' 44%, 'premature ejaculation' 15%, and 'delayed ejaculation' 50%. 2) The PRL, 5-HT levels of schizophrenics($28.5{\pm}20.6ng/ml$, $298.5{\pm}89.1ng/ml$) were significantly(p<0.001) higher than those of controls($10{\pm}5.6ng/ml$, $169.2{\pm}37.8ng/ml$), while the TST levels of schizophrenics($4.3{\pm}1.5ng/ml$) and controls($4.5{\pm}1.2ng/ml$) were not significantly different. The sexual dysfunctions of schizophrenics who had abnormal 5-HT levels($4.7{\pm}1.3$ scores) were significantly(p<0.05) higher than those of who had normal 5-HT levels($3.8{\pm}1.6$ scores) on item D7. 3) The sexual dysfunctions of unmarried schizophrenics were significantly(p<0.01 : p<0.05) higher than those of married schizophrenics($6.1{\pm}2.8$ scores, $4.7{\pm}1.3$ scores on item FGa : ${\beta}$=-0.211 on item FNa). The sexual dysfunctions were positively correlated with the rise of 5-HT levels(r=0.209, p<0.05 on item D4 and r=0.241, p<0.05 on item D7), the higher age at onset(r=0.275, p<0.01 on item FNa : r=-0.202, p<0.05 on item FDa), the longer duration of illnesses(r=0.237, p<0.05 on item D6), the longer duration of admission(r=0.234, p<0.05 on item D4 : r=0.328, p<0.05 on item D6), the longer total duration of medication(r=0.237, p<0.05 on item D6). However, age, education, religion, economic status, PRL, TST levels, antipsychotics dosage, potency, benztropine, ACSE, CGI, BPRS, PANSS, PANSS-CF, MMSE-K scores were not correlated with increased sexual dysfunctions. Conclusions : Male schizophrenics have significantly more sexual dysfunction to compare with controls. The higher frequencies of sexual dysfunctions were low sexual desire and erectile disorder. The unmarried, higher age at onset, and longer duration of diseases were positively correlated with increased sexual dysfunctions. Also high 5-HT levels were positively correlated with increased sexual dysfunctions. This means that studies of plasma 5-HT levels, albeit questionable indicators of central 5-HT function, offer some additional support for the association of sexual dysfunction with excess 5-HT activity as primary pathology of schizophrenia. Our findings suggest that excess 5-HT activity seems to affect the patient's sexual function.
