  • Objectives: In recent years, pregnancy rate among female adolescents has increased and caused a variety of physical and social problems. Therefore, this study aimed to investigate sexual behavior, delinquent behavior, and pregnancy rate among Korean female adolescents. Methods: In light of the growing interest in adolescent pregnancy, this study conducted a web-based survey, titled "The 2006 Youth Health Risk Behavior Survey." The Korean Center for Disease Control (KCDC) collected questionnaire responses from 34,200 young women. The collected data were analyzed through chi-square test and logistic regression using SPSS Win 14.0 version. Results: This study analyzed main factors, which can predict pregnant experience. The statistic results showed two types of the predicting factors: (1) personal factors: sexual relations after drinking (odds 25.1), Narcotic drug taking (odds 13.0), sexual violence act (odds 7.0), part-time job(odds 2.5), drinking, smoking ; and (2) environmental factors: stepfather(odds 4.2) and natural mother. Conclusion: The influential factor identification for predicting pregnancy rate is important to develop an effective education program for preventing the adolescent pregnancy. The education programs with referring to the identified factors can contribute to reducing the unwilling pregnancy rate of young woman.

  • The present study is aimed at evaluating the economic effectiveness of Abalone, haliotis discus hanai Releasing Project(ARP) conducted in the fishing ground owned by a fishing village in Ulsan, Korea. The results were summarized as follows: First, an average ratio of released abalones in the total landing after releasing is shown to be 85.0%. Second, the recapture rate of released abalones is 46.8%, exceeding the recapture rate of BEP(Break-Even-Point), 22.9%. Third, it is evaluated that total economic effectiveness of the ARP is 6.7-6.8 times, net effectiveness is 2.2-2.3 times, and the NPV(Net Present Value) discounted by a 8% interest rate is 474, 635 thousand wons, indicating the project is profitable. Considerable parts of the positive results on the ARP are based on some beneficial conditions, including the selection of favorable releasing sites, best self-regulation system of a fishing village for preservation of seaweed facilities and continued activities for protecting small abalones and their rearing. These results imply that the success of the ARP would be primarily dependent upon the selection of releasing site and effective management system after releasing.

  • Ultra-short laser pulses are effective, when high requirements concerning accuracy, surface roughness and heat affected zone are demanded for surface structuring. In particular, picosecond laser systems that are suited to be operated in industrial environments are of great interest for many practical applications. This paper focused on inducing optimum process parameters for higher volume ablation rate by analyzing a relationship between crater diameter and optical spot size. In detail, the dependency of the volume ablation rate, penetration depth and threshold fluence on the pulse duration 8 ps and wavelength of 515 nm was discussed. The experimental results showed that wavelength of 515 nm resulted in less threshold fluence ($0.075J/cm^2$) on copper than IR wavelength ($0.3J/cm^2$). As a result, it was possible that optimum fluence for higher volume ablation rate was achieved with $0.28J/cm^2$.

  • In this study, the interest of female high school students's(N=500) for weight control, as well as nutrient intake status, were analyzed. The mean age, height, and weight of the subjects were, 19.3 years, 162.2 cm and 55.4 kg respectively. Mean BMI was $21.1 kg/m^2$. According to BMI, the percentage of underweight, normal weight, overweight, and obese were 18.5 %, 60.3%, 11.3%, and 11.3% respectively. By the BMI criteria, 60.3% of the subjects were normal weight while the rate of self-recognition was 41.5%. The degree of satisfaction regarding self-body image was only 17.1% and 60.9% showed an interest in weight control. The reason for weight reduction were appearance(65.1 %) and health(24.2%). The body areas where subjects wanted to lose weight included the thighs(32.9%) and whole body(29.3%). They believed the most effective weight control strategy was exercise(81.1 %) and the strategies they used were diet(59.1 %) and exercise(40.4%). Energy intake was 1,733.4 kcal which was 86.7% of the estimated energy requirements(EER). Calcium, vitamin $B_2$, and vitamin C intakes were less than EAR by 34.4%, 40.4%, and 59.6% respectively. The intake of dietary fiber was 5.1 g only 21.1 % of the adequate intake(AI). In summary, high school females interested in weight control have significantly less calcium intake than their peers. The correlations between interest in weight control and weight and BMI were significant(p<0.001). The results of this study suggest that to achieve optimal growth, improved diets that include calcium, vitamin $B_2$, and vitamin C are recommended. High school females interested in weight control should especially be targeted for education on calcium intake.

  • Trigger finger is a common cause of hand disability that results in finger catching, clicking, or locking. Conventional treatment options such as medication, injection, and surgery have limitations. Studies have indicated that acupuncture and acupotomy can be effective in treating trigger finger. However, no review regarding these treatment modalities has been published yet. This review included randomized controlled trials published until January 2023, investigating acupuncture-related interventions. The primary outcomes of interest included the effectiveness rate (ER) and pain intensity, measured using a visual analog scale (VAS) and Numerical Rating Scale (NRS), and secondary outcomes were the Quinnell grade (QG) and recurrence rate (RR). Adverse events (AEs) have also been reported wherever available. Overall, 19 studies were included, and results demonstrated that arcedge acupuncture improved the ER and QG and reduced NRS, and acupuncture was effective in reducing VAS. Compared with conventional surgery, acupotomy alone improved the ER and QG and lowered VAS and RR, with relatively fewer AEs. Acupotomy add-on treatment was more effective than conventional treatment; however, careful interpretation is needed for VAS. Acupotomy add-on treatment was more effective than acupotomy alone. However, the overall results must be interpreted with caution because of study quality, small sample size, and heterogeneity of the results.

  • This study in order to seek for a more effective teaching method, I am to propose a measure that the career education material for female middle school students a program produced already could be applicable on the class and to understand the efficiency by examining practically it to the student. The research method was to make up a questionnaire and gaze two kinds of educational effect. The procedure was that, after surveying the general features in order to help them known their consciousness on the career education Researcher practiced common theorectical teaching on comparative class and moduling teaching on comparative class through making a guiding data. Then Researcher analysed the changing o consciousness on career, knowledge on kinds and numbers of jobs, and the results and rate of interest in the teaching with persentage and t-test. The results are as followed; First, on the consciousness on career, both group showed little change on their wishful job between before and after teaching. On the purpose to get a job, consciousness on work and job, and fixed idea of job on gender, there were some changes, but both groups had few defferences in the changing rate. Second on the consciousness on work and job experimental group recognized the variety of job more than comparative group and wrote more hind of job. Third on the evaluating result, the record of experimental group was higher. Fourth, on the rate of interesting in learning the rate of experimental group was higher. As observed the class applied by the module of female career education is effective, since experimental group showed more consciousness on work and job, evaluation of record after teaching and the rat of interesting in learning, through there was no difference in the consciousness of the career.

  • Purpose - This paper aims to analyze the impact of the terms of trade, export price, and import price on the Korean economy (that is, real GDP, CPI, money market rate, and real effective exchange rate), and vice versa in the simple vector autoregression. Design/methodology - We impose two assumptions, i.e., diagonality and bloc exogeneity, to correctly identify the impact of a factor to the others in the structural equation. With two contemporaneous assumptions in the structural VAR, this paper investigates the impacts of the terms of trade on the Korean economy and vice versa. Findings - Impulse responses to the shocks in the terms of trade and Korean economy show that 1) an impact of the terms of trade on the economy is different in export prices and in import prices. A higher export price is beneficial to the economy while a higher import price hurts the economy, and 2) an increase in real effective exchange rate and in interest rate constrains domestic production and lowers consumer prices. Originality/value - Unlike the conventional perception that a depreciation of a currency would promote exports and domestic production at the price of inflation, our result shows the opposite, and 3) real GDP and consumer prices are positively correlated. That is, an increase in real GDP does not only cause inflation, but an increase in consumer prices also promote domestic production. Yet, the only difference is that export prices and import prices end up higher with an increase in real GDP, but lower with inflation.

  • Korean medicine has traditionally provided a lot of medical care for the treatment of infertility. The combination treatment of Korean medicine and Western medicine can be effective for infertility to improve the problems caused by the extremely low fertility rate and the aging of pregnant women. In relation to female infertility, we reviewed the evidence for Korean medicine treatment for polycystic ovary syndrome, which has recently been increasing interest in female infertility, and the evidence for the collaboration between Korean and Western medicine in the treatment of polycystic ovary syndrome and infertility. Because polycystic ovary syndrome is closely related to metabolic diseases related to endocrine abnormalities, hormone treatment alone has limited therapeutic effects and has side effects. In domestic and international research, herbal medicine and acupuncture in the treatment of infertility have shown good clinical effects based on the hypothesis of various mechanisms of effect, and many cases of successful pregnancy have been reported. Although continuous research through large-scale randomized clinical studies is needed to prove efficacy, the importance of combined treatment of Korean medicine and Western medicine in infertility treatment is increasing in order to solve the extremely low fertility rate. Combining artificial insemination or in vitro fertilization with Korean medicine treatment is highly likely to be effective in increasing pregnancy success and fertility rates. In women with polycystic ovary syndrome, which is recognized as a metabolic disease due to endocrine abnormalities among the causes of female infertility, Korean medicine treatment can increase the pregnancy rate with herbal medicines and acupuncture, etc. Although well-designed large-scale clinical studies are currently lacking and meta-analysis has not provided sufficient evidence, the combination treatment of Korean medicine and Western medicine is more active to increase the pregnancy rate for solving the problem of low fertility.

  • The study investigates the effectiveness of the macroprudential policy on credit growth in Vietnam. The authors use the logic of the transmission mechanism of macroprudential policy on credit growth. Research variables include economic growth, inflation, interest rate, and quarterly bank-level data from 28 commercial banks in Vietnam during 2011-2018. The results reveal that: (i) GDP growth had a positive impact on credit growth of small banks but had no impact on large banks, (ii) Domestic Systemically Important Banks (D-SIBs) and small banks respond differently to macroprudential measures of imposing different credit growth targets for different bank groups, (iii) Restrictions on foreign currency loans are found to be effective in curbing credit growth for the full sample and small banks, (iv) Inflation and economic cycle have significantly impacted credit growth at bank-level in Vietnam and (v) Interestingly, a significant positive relationship between interest rates and credit growth is found for the full sample and D-SIBs in Vietnam. The findings suggest that a stable macroeconomic environment should be good conditions for financial stability, and monetary authority should pay more attention to small banks' behaviors than D-SIBs behavior, toward such "administration" tools since small banks tend to prefer "breaking the rules" to make profits.
