Objectives : The objective of this study is to discuss problems and potential improvements of national health insurance fees associated with miniscalpel acupuncture according to Korean medical doctors' workload, material cost and degree of risk. Methods : We researched the change of relative value points, national health insurance fees, the acupuncture process, and Korean medicine doctors' workload related to Miniscalpel acupuncture, as compared to general meridian point acupuncture. We also examined material cost by surveying pharmacies, internet shopping malls and medical appliance shops. Results : Relative value point for Miniscalpel acupuncture decreased from 2010 to 2012, and remained the same from 2012 to 2016. National health insurance fees for Miniscalpel acupuncture increased by a small margin annually for rise of equivalent index. There was no reporting on workload related to Miniscalpel acupuncture. Material cost of Miniscalpel acupuncture was 18.2~20.7 times higher than actual cost of procedure. There were few studies examining medical accidents related to Miniscalpel acupuncture, and thus we could not evaluate degree of risk. Conclusion : We suggest revaluating Korean medical doctors' workload related to including Miniscalpel acupuncture, to consider the material costs of Miniscalpel acupuncture, and investigate its degree of risk by researching medical accidents.

The purpose of this study was to investigate the weight control behaviors, the degree of fatness and dance major on behalf of finding the effects of eating disorders. 779 female high school students, 283 dance major students and 496 general major students, were participated in the study. A self-reporting type of questionnaire survey was conducted during the period from $6^{th}$ May to $18^{th}$ April of 2005. Collected data were processed using SPSSW in 12.0; they were analysed through frequencies, percentages, means and standard deviation, and stepwise multiple regression analysis. The results of this study are as follows : 1. With regard to the level of eating disorders(EAT-26), 33.9% of risk group of eating disorder female dance students, and 13.7% of risk group of eating disorder female general major students. Weight-control behaviors in this research were 1) weight control concerns, 2) weight control trial, 3) weight control methods (prescription of M.D., ways of weight control), 4) eating habits. First, 56.6% of subjects had high concerns about weight control, and 92% of subjects had tried weight control. Second, only 5.1% of subjects were prescribed by M.D. Third, subjects had been using wrong methods(25.7%) of weigh control such as fasting, using drugs, vomiting, wearing laps etc. Fourth, 42.7% of the subjects had bad eating habits. The degree of fatness was as follows: 1) BMI(Body Mass Index), 2) self report about weight 3) distorted body image. Depending upon the BMI, the subjects with obesity were not found in female dance students; Comparatively, 36.9% of dance students were fat and 1.4% of the students were very fat. In terms of distorted body image, only 14.9% of all subjects were the same between the subjective degree of fatness and the objective degree of fatness. 2. As a result of multiple regression, six variables were found significant($R^2=11.6%$, P < 0.01). Concerns about the weight control significantly influenced on eating disorders(EAT-26). At the same time, major(dance), wrong methods of weight control, distorted body image, prescription of M.D, and eating habits had significantly influenced on eating disorders. This results indicates that the risk of eating disorders among female dancer students was very high. Therefore, professional intervention is needed for female dance students to prevent the eating disorders.

Background: Endemic circulation of human-specific hepatitis E virus (HEV) genotypes 1 and 2 may occult the importance of sporadic zoonotic HEV transmissions in Africa. Increasing numbers of studies reporting anti-HEV antibodies in cattle and the discovery of infectious HEV in cow milk has raised public health concern, but cattle exposure has seldom been investigated in Africa. Objectives: This study aimed at investigating the role of cows in the epidemiology of HEV in Burkina Faso and farmers habits in terms of dairy product consumption as a prerequisite to estimate the risk of transmission to humans. Methods: Sera from 475 cattle and 192 pigs were screened for the presence of anti-HEV antibodies while HEV RNA in swine stools was detected by reverse transcription polymerase chain reaction. Data on mixed farming, dairy product consumption and selling habits were gathered through questionnaires. Results: The overall seroprevalence in cattle was 5.1% and herd seroprevalence reached 32.4% (11/34). Herd seropositivity was not associated with husbandry practice or presence of rabbits on the farms. However, herd seropositivity was associated with on-site presence of pigs, 80.7% of which had anti-HEV antibodies. The majority of farmers reported to preferentially consume raw milk based dairy products. Conclusions: Concomitant presence of pigs on cattle farms constitutes a risk factor for HEV exposure of cattle. However, the risk of HEV infections associated with raw cow dairy product consumption is currently considered as low.

Objectives: The purpose of this study was to assess the effect of Yigong-san on anorexia in children by conducting a systematic review and meta-analysis of randomized controlled trials (RCTs). Methods: Eleven electronic databases were searched on May 30, 2022 to collect relevant studies. All studies published up to the search date were considered. RCTs reporting the effect of Yigong-san on the treatment of anorexia in children were included. The primary outcome was an improvement in clinical anorexia symptoms after treatment. In this meta-analysis, continuous and binary outcomes were assessed, and the data were presented as the mean difference and risk ratio with their 95% confidence intervals. The risk of bias was assessed using the Cochrane Collaboration's risk of bias tool. Results: A total of nine studies were included in this systematic review. The treatment group (Yigong-san only or Yigong-san plus conventional treatment) showed a statistically significant effect compared to the control group (conventional treatment only) in total effective rate (Yigong-san only: RR 1.26, 95% CI 1.17, 1.36, I²=0%; Yigong-san plus conventional treatment: RR 1.32, 95% CI 1.18, 1.47, I²=0%), clinical symptoms, some of the anthropometric outcomes, and biological markers related to appetite and growth in children with anorexia. No serious adverse events related to Yigong-san were reported. Conclusions: Yigong-san showed statistically significant effects as a treatment for anorexia in children. However, the number of studies included in the meta-analysis was insufficient, and the herbs contained in the Yigong-san used in the included studies were not standardized. Future research should focus on the implementation of methodologically robust clinical research.

This article discussed the characteristics of several Pareto-optimal incentive contracts between owner and labor, more specifically, four situations: reporting output jointly observable by labor ana owner; reporting both output and effort; incorporating other endogenous elements (like capital) that affect the production process and Pareto-optimal fee schedules; and ascertaining the effects of private pre-decision information private- decision information, and per-contact informational asymmetries. Also presented were several extensions of the basic contractual model, and the different components of agency costs associated with labor-owner contractual relations. In a single-period model, the agency problem exists because the uncertainty prevents the owner from using the cash flow to determine unambiguously the labor's action. Holmstrom(1979) suggests that "when the same situation repeats itself over time, the effects of uncertainty tend to be reduced and dystunctional behavior is more accurately revealed, thus alleviating the problem of moral hazard. " Under these conditions, if the labor selects the first-best level of effect in each period, the cash flow will be independent and identically distributed over time. As the number of periods increases, the variance of the labows average output, if he selects the first-best level of effort in each period, gets smaller. Note that for this diversification effect to occur, it is necessary that the owner evaluate the labor's effort over the entire history of his employment, rather than evaluate each period's performance separately. Radner(1980) and Rubinstein and Yaari(1980) consider the extreme case in which there are an infinite number of observations. They show that the owner can eventually detect and systematic shirking on the part of the labor by comparing the labor's average output with what would be expected if the labor had been selecting the first-best level of effort in each period. In a dynamic model with incentive problems we have demonstrated that the labor's second-period compensation will depend on his first-period performance. This allows the owner to diversify away some of the uncertainty surrounding the labor's actions. In addition, this allows the owner to smooth the labor's income over time by spreading the risk of the first-period outcome over both periods. At least some unexplored avenves in this area invite future accounting research: situations where owner has different incompatible objectives and negotiates a contract with labor; circumstances in which owner deals with multiple objectives and negotiates contracts with several labors simultaneously; the value of costly accounting information systems and communication in establishing, Pareto-optimal incentive contracts, and the value and effects of inside information, Thorough theoretical or empirical research on each of these topics not only would increase our knowledge about the role and significance of accounting information but could also provide explanations of the inherent differences among various organizations and in their economic behavior. behavior.

The aim of this study was to investigate the effect of sleep duration on dietary habits and body composition of university students. Sleep duration has recently been added to the list of risk factors for obesity. However, studies on this topic are fairly limited particularly in Korea. We studied the relationship between the duration of sleep and obesity principally based on body mass index and %body fat in university students. For this purpose, a survey was conducted on a total of 312 university students. The subjects enrolled for this study were divided into two groups: (1) those with sleep duration of <7 hours (148 students) and (2) those with sleep duration of >7 hours (164 students). Based on a self-reporting method, the participants filled up the questionnaires for more than 20 minutes. Based on the overall data obtained, we observed that most students (52.88%) skipped breakfast. This was mainly due to shortage of time (60.58%). We also observed that self-reporting dietary preferences included eating irregular meals (49.04%), overeating (19.55%), imbalanced diet (16.35%), and skipping meals (9.94%). It was found that cookies were the favorite snacks in the majority of the participants (50%). Our data reveal that the body mass index, fat mass, visceral fat, and subcutaneous fat, respectively of the shorter sleep duration group (<7 h/day) were 23.78 $kg/m^2$, 19.13 kg, 2.23 kg, and 11.15 kg. In contrast, in those of the control group (7 h/day), these values were found to be 21.84 $kg/m^2$, 13.88 kg, 1.56 kg, and 12.11 kg. We also observed that there were significant correlations of sleep duration with body mass index (p<0.05), fat mass (p<0.01), visceral fat (p<0.01), and beck depression score (p<0.01). Our data suggest that the body mass index in the shorter sleep duration group was higher than that of the control group; however, %fat, visceral fat, and subcutaneous fat in the shorter sleep duration group were found to be higher than those of the control group. The data obtained through our study suggest that short sleep duration is clearly associated with a modest increase in general and abdominal obesity particularly in university students.
