Recently in Korea, integration of F.P. & MCH programs for effective and efficient implementation of the health programs has been discussed actively. In fact, categorical health workers in fields have been trained and changed as an integrated health workers by government. But one of the most important problems that had to be solved for successful integration of F.P. and MCH programs, is that there must be a common indicator for the evaluation of the two health services (integrated indicator). We regarded reproductive efficiency (=R.E.) that had been proposed by Charlotter M$\ddot{u}$ller et al, as the good integrated indicator. The object of this brief article is to introduce the meaning of reproductive efficiency and to illustrate the usefulnesses of R.E. as the integrated health indicator by applying this indicator to the data from preliminary survey of Seosan demonstration project for integration of F.P. & MCH service supported by WHO. The results and conclusions are as follows 1) Definition of R.E. is the percentage of pregnancies that succeed in production normal, surving children after taking into account the frequency of all measurable types of adverse outcomes (End point for evaluation of survival is one year of age). 2) On the basis of the past pregnant history, reproductive efficiency of the 2,484 eligible women (15-44 years) was roughly 75% (But, in the concept of good births, it is not regarded whether the survived infant is normal health or not). 3) Compared with the results of the other two surveys of the rural area in Korea, reproductive efficiency has been slightly decreased than before, in spite of family planning and MCH services for past 20 years. Because the quantity of increased abortion rate overwhelmed that of the decreased infant mortality rate. 4) Reproductive efficiency has the object for measure many events during the period from the conception (Wanted pregnancy) to an normal surviving children as an 1 year of age. So these heterogenous adversities, ie, induced abortion, still births, spontaneous abortion, neonate & infant death, are aggregated as R.E. However, if the information of these important events and reproductive efficiency were given, R.E. is used as the comprehensive evaluation indicator for F.P. and M.C.H. after meticulous analysis the various components of R.E. 5) Economic loss for adverse outcomes of preg were pregnancy were calculated applying the medical cost at the relatively small sized hospital of small city. Economic loss for 100 cases of adverse outcome is 10,420,000 won, and economic loss for infant death is 46.1% of the total loss. So, it is rational to invest much more effort and than before to MCH programs.

This study was a descriptive research on the level of self-care available to continous ambulatory peritoneal dialysis patients (hereinafter referred to as 'CAPD patient') related to the specific area of infection management. The method employed for the collection of data was a modified instrument of the self-care survey essentially based on Young Sook Choi's instrument. The relevant data was collected from september 1, 1996 to september 30, 1996. The subjects were provided with an open-ended question regarding the reasons behind why they did not seek self-care. The answers provided about self-care compliance were analyzed by SPSS for frequency, percentage, mean, t-test, ANOVA. Reasons for non-compliance were analyzed by content analysis. The results of the study were as follows : 1. The percentage of patients engaging in self-care were according to the following self performed tasks : preparation of dialysis : 30.58 points Dialysate exchange procedures : 49.40 points - Two bag type : 50.50 points - Spike type : 48.80 points - Neo type : 48.90 points Catheter exit site care : 25.13 points More specifically, in relation to the preparation of dialysis as referred to above, those patients engaging in self care was relatively high with respect to the cleaning of the dialysis before use and for the preservation of peritosol. However, in dialysate exchange procedures, data revealed that those patients engaging in self-care are relatively low with respect to putting on a mask during the performance of peritosol exchange. Similary in peritosol exchange procedure and catheter exit care, low levels of self-care performance were found in the area of putting on a mask during the peritosol exchange procedures and catheter line testing procedures, respectively. 2. In general characteristics, there appeared to be no distinction in self-care compliance among CAPD patients. 3. The main reasons for non-compliance were based in the following factor : intellectual, attitude, enviromental surrounding and physical. As a result of the foregoing finding, nurses should provide adequate assistance to promote self-care compliance by CAPD patients by checking the preparation of dialysis, dialysate exchange procedure, and catheter exit site care which recieved low point in this research.

The effects of inner liquid sloshing on vessel motions are a well-known factor. It was investigated experimentally and numerically. In this regard, the study of many efforts to reduce natural phenomena of vessel motions by adopting special devices especially for roll motions. Among many devices, inserting baffles in the inner liquid tank is very common. In this study, one investigated the vessel motions with inner sloshing tanks with baffles inside. For the numerical simulation, one employed a dynamically coupled program between boundary-element-method-based vessel motion analysis program and a particle-based computational fluid dynamics program. Comparing corresponding experimental results validated the dynamically coupled program. The validated coupled program was used to simulate vessel motions, including sloshing effects with various lengths of inner baffles. The simulation results show that not only the filling ratio of inner liquid, but also the length of clearance due to baffles influenced the vessel motions. The significant point of this study was that the natural frequency of vessel motions can be maintained irrespective of the amount of filling ratio through adjustment of the clearance. In a future study, the effects of various numbers of baffles with various clearances would be conducted to percuss the possibility of vessel motion control with inner liquid sloshing effects.

In this paper, the effects of a metamaterial slab with negative permeability in a magnetically coupled wireless power transfer system (WPT) in the overall performance are analyzed quantitatively in terms of the effective quality factors of the loop resonators and coupling coefficient considering the slab losses, based on an equivalent circuit. Using the ideal metamaterial slab(lossless slab), the WPT efficiency is improved considerably by the magnetic flux focusing. However, the practical lossy slab made of RRs or SRRs limits the significant enhancement of WPT efficiency due to the relatively high losses in the slab consisting of RRs or SRRs near the resonant frequency. For the practical loop resonator, other than a point magnetic charge, using the practical lossy metamaterial slab in order to improve the transfer efficiency, the width of the slab needs to be optimized somewhat less than the half of the distance between two loop resonators. For the low-loss slab with its loss tangent of 0.001, the WPT efficiency is maximized at 93 % when the ratio of the slab width and the distance between the two resonators is approximately 0.35, compared with 53 % for the case without the slab. The efficiency in case of employing the high-low slab(loss tangent: 0.2) is maximized at 61 % when the slab ratio is 0.25.

The increasing rate of obesity in school aged children has become a conspicuous social phenomenon in Korea. This has been linked to greater economic growth, increasingly westernized dietary habits, and a consumer driven society. Given that obesity can lead to social exclusion or unfavorable attention by other students in a school setting, the design of plus-size garments have become important for effective appearance management skills. This research aimed to establish a somatotype database for obese school boys, aged 10 to 12, in order to develop a sizing system for plus-size upper garments. In order to measure somatotype of average and obese school boys, five categories were recorded; height, obesity, length of trunk, thickness of neck and chest. For obese boys, subcutaneous fat thickness and position of B.P/shoulder point factors were recorded. Obesity factor was subdivided into overall and specific ones, and while the deviation of obese body types was severe compared to the average type. Obese body type showed significantly higher measurements in width, girth, thickness. This is linked to the fact that the frequency ratio of obesity increases with age. Stature and chest were chosen as control dimensions for boys' wear. As crosstabulation of stature(5cm interval) and chest girth(2, 3 and 4cm), and stature(5cm interval)/chest girth(3cm interval) sizing system showed, the most effective cover ratio and adaptability to the data distribution $25{\sim}75$ quartile. Based on the findings, 10 sizes were formulated for average body type, while 18 sizes were formulated for obese type, whose size cover ratios were 48% and 62.9%, respectively. The primary ranges of stature were $145cm{\sim}150cm$, while those of chest girth were $79{\sim}82cm$. Each size was declared as "chest-somatotype{A(average)/O(obesity)-stature". This study proposed a plus-size upper garment sizing systems for obese boys, accompanied with reference measurements for suit, casual wear and underwear. The finding showed that the two systems were totally separate and not overlapping, meaning that plus-size sizing system is essential for obese school boys. The obesity type system had more size and wider range specs.

The purpose of this study was to examine the relationship among perceived health status, self-esteem, self-efficacy and health promoting behavior, and to determine the predictors of health promoting behavior in post-mastectomy patients. The study, a descriptive correlational study, was done with structural questionnaires. A total of 51 post-mastectomy subjects from C university hospital in Kwang-ju, South Korea completed mail-in self-reporting questionnaires during a three month period from March to June, 1999. The data were collected using Lawstone's(1982) perceived health status scale, Rosenberg's(1965) self-esteem scale, the modified self-efficacy scale(Shere et al, 1982), and the modified health promoting lifestyle profile (Walker et al, 1987). The data obtained were analyzed according to percentage, mean and standard deviation, principal component analysis, varimax rotation, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression. The results were as follows: 1. The health promoting behavior measurement resulted in six factors. Each factor was labelled as follows: self-actualization, nutrition, stress management, exercise, health responsibility and interpersonal support. The total percent of variance explained by the six factors was 58.4%. 2. The mean score of health promoting behavior was 85.92(range 58~117). The scores of six factor were nutrition 3.20, self-actualization 2.59, stress management 2.58, interpersonal support 2.58, health responsibility 2.49, and exercise 2.34 on a four point scale. 3. When the score of health promoting behavior factors were compared by general characteristics. Factor I: self-actualization, differed significantly by the frequency of pregnancy (F=3.06, p=.037). Factor II: nutrition differed significantly by drinking experience(t=-2.26, p=.028) and the pre- or post stage of menopause(F=2.69, p=078). FactorIII: stress management differed significantly depending on regularity of mensturation(t=-2.12, p= .042). FactorIV: exercise differed significantly by type of religion (F=2.49, p=.072), marital status(F=5.03, p=.010), and feeding type (F=2.64, p=.036). Factor V: health responsibility differed significantly by regularity of mensturation(t=2.18, p=.037). 4. The total health promoting behavior score was significantly related to self-esteem and perceived health status(r=.610, p.006; r= .378, p=.006). The score of selfactualization also corresponded with selfesteem and perceived health status(r=.556, p=.001; r=.343, p=.013). 5. The predictor to explain the score of health promoting behavior was self-esteem, which accounted for 37.1% of the total variance. The predictor to explain the score of self-actualization was self-esteem, which accounted for 30.9% of the total variance. The score of nutrition was primarily affected by both premenopause and drinking experience, which accounted for 13.1% and 9.5% respectively. Finally, the score of exercise was dictated by marriage, Buddhism, no experience of breast feeding, which accounted for 17%, 9.8%, & 5.2% respectively. In conclusion, self-esteem is the main predictor for health promoting behavior in post-mastectomy women. These findings suggest a need for nursing strategies which promote self-esteem in such patients.

This study purposed to analyze dental hygienists' job satisfaction according to their clinical career as an effort to enhance their job satisfaction and quality and to provide basic materials for dental hygienists' effective job performance. For this purpose, we surveyed 120 dental hygienists working at dental hospitals and clinics in Busan during the period from the $1^{st}$ February to $31^{st}$ March 2009 by using a self administered questionnaire. Job satisfaction was measured using a 5 point Likert scale ranging from 'Absolutely yes' (5 points) to 'Yes' (4), 'So so' (3), 'No' (2), and 'Not at all' (1), and a high score indicates high degree of satisfaction. When it testd the reliability of the job satisfaction scale was tested, Cronbach's Alpha (${\alpha}$) was 0.85 which indicates the instrument is sufficiently reliable. Data collected were analyzed with SPSS. We performed frequency analysis in order to examine the subjects' demographical characteristics, and Chi square and one way ANOVA to examine their perception of their job, job satisfaction, and their aptitude and status as a dental hygienists' according to clinical career. The results of this study were as follows. 1. The longer clinical career the dental hygienists had, the more they thought that they had aptitude as a dental hygienist (p<0.05). 2. The dental hygienists' turnover intention was different according to clinical career (p<0.01). 3. The longer clinical career the dental hygienists had, the more satisfied they were when they were working at a dental hospital or clinic equipped with convenience facilities (change room, lounge, etc.) (p<0.01). 4. The longer clinical career the dental hygienists had, the more power to make decisions they had and the more acknowledgement and trust they received from dentists (p<0.01). 5. Satisfaction with duty coordination was low in general, but it grew higher with increase in clinical career (p<0.01). 6. The longer clinical career the dental hygienists had, the more satisfied they were with patients' appreciation of their treatment (p<0.01). In addition, their time and opportunities to discuss with dentists were different according to clinical career, and their satisfaction with the items was higher when their clinical career was long (p<0.01). 7. As to their perception of dental hygienists' potential for development, they generally believed that they had potential for future growth with the expansion of their work scope (M=3.73). The longer clinical career the dental hygienists had, the more satisfied the more power to make decisions they had and the more acknowledgement and trust they received from dentists and their time and opportunities to discuss with dentists when they were working at a dental hospital or clinic equipped with convenience facilities (change room, lounge, etc.). The longer clinical career the dental hygienists had, the more they thought that they had aptitude as a dental hygienist. In conclusion, the longer clinical dental hygienists' Career had, satisfaction was able to take a highness to a dental hygienist occupation.
