Objective: The aim of this study was to investigate the effect of insulin sensitizing agents on hormonal and metabolic parameters as well as menstrual patterns in women with polycystic ovary syndrome (PCOS). Methods: One hundred and twenty-three patients with PCOS were included. Metformin was administered to patients at 1,500 mg or 1,700 mg daily for 3 months. If the patients had no improvement of the menstrual cycle or metformin-related adverse effects developed, the patients changed medication to a daily dose of either 15 mg pioglitazone or up to 45 mg. Then resumption of a regular menstrual cycle or recovery of ovulation was evaluated. Hormonal and metabolic profiles were compared between the response and non-response group to insulin sensitizing agents. Results: One hundred and five patients with PCOS were treated with metformin for 3 months. Forty-eight patients (45.7%) showed improvement of menstrual cycle regularity after 3 months of metformin use, whereas 57 patients (54.3%) had no change. The mean free testosterone measured after 3 months of treatment was significantly lower in metformin responders than in non-responders. The other parameters did not differ between the groups. Of the 23 patients who used pioglitazone for 3 to 6 months, 19 patients (82.6%) showed improvement in their menstrual cycles. Conclusion: Metformin treatment seems to be effective for the improvement of menstrual cyclicity irrespective of insulin resistance in women with PCOS. When metformin related adverse effect occurred, pioglitazone would be effective for aiding the resumption of the menstrual cycle.
This study aims to analyze whether both childcare subsidy and childcare leave policies have moderating effects on the relationship between Korean women's value of children and their intentions for subsequent childbirth. The data are used from the 2015 National Survey on Fertility and Family Health and Welfare. Both hierarchical multiple regression analysis and moderated regression analysis are used for statistical analysis. The findings from the study are as follow. First, the ideal number of children, instrumental values, and emotional values have positive effects on the intentions for subsequent childbirth after controlling for background variables(level of education, income, age, and number of children). Second, childcare leave policy has no significant effect on the intentions for subsequent childbirth while childcare subsidy policy has the negative effect. Third, only childcare subsidy policy has moderating effects on the relationship between instrumental, emotional values, and the intentions for subsequent childbirth. These results suggest that policies enhancing the value of children should be implemented in addition to traditional birth rate policies. Furthermore, new birth rate polices are needed for those married women who have a high possibility of subsequent childbirth.
This study attempts to review the increasing trend in international marriage of Koreans since 1990 and explore the pattern of socio-demographic characteristics of the married couples. This paper develops a conceptual scheme for changing pattern of nuptiality including an increase in international marriage. As the key forces behind the recent increase in international marriage of Koreans, the effects of rapid decline in fertility, rise in sex ratio at birth, urbanward migration of young women, expansion of gender-equity norms, and globalization are stressed. Micro-data from the marriage registration for the period $1990{\sim}2004$ and the divorce registration for the period $2000{\sim}2004$ are utilized. This study focuses on analyzing age at marriage, previous marital experience, education, occupation, and residence of the married couples. Attention is also focused on demographic characteristics of the divorced couples. Results of analyses reveal that there exists a great deal of diversity in international marriage of Koreans. A notable aspect is the profound differences between Korean men and women in the characteristics of their foreign spouses and themselves as well. Another prominent factor emphasized in the analysis is the nationality of foreign spouse. It is indicated that the stereotype of international marriage facilitated by marriage squeeze can be mainly applied to marriages between Korean men and foreign wives from China, southeast Asian countries and the CIS of the old Soviet Union. On the other hand, direct effects of value transformation and globalization are emphasized in the explanation of marriages between Korean men and foreign wives from more developed countries as well as marriages between Korean women and foreign husbands.
Objectives: The purpose of this study is to collect and analyze the KCD codes applied to the treatment of 27 postpartum women who had been treated with Korean traditional medicine in a Korean medicine hospital, so that this study may be used as a basic data for setting the direction of postpartum Korean medical treatment research. Methods: It was approved by the Institutional Review Board (IRB) of ${\bigcirc}{\bigcirc}$ University medical center (IRB approval number : WSOH IRB H1708-02-01). Twenty-seven postpartum women who had been treated at ${\bigcirc}{\bigcirc}$ University medical center were received outpatient treatment for two weeks (from September 27, 2017 to January 5, 2018), and the KCD codes applied to the mothers were collected after obtaining the consent. On the day of registration of the study, the fertility, obstetric history and high-risk pregnancies were identified through an interview. Results: 1. The mean age of the 27 subjects was $33.33{\pm}3.99\;years$ old. Among the subjects, 17 mothers (63.0%) were high-risk pregnancy and 10 mothers (37.0%) were normal. 2. Among the 22 major disease categories, 8 categories were used. M code (musculoskeletal system) was used 243 times (70.85%), followed by R code (unclassified symptom) of 51 times (14.87%) and U code (special purpose code) of 23 times (6.71%). 3. The most commonly used code among the ten frequently used codes was M25.57 (joint pain, ankle and foot), a total of 47 times. Of the remaining nine codes, except for R60.1 (systemic edema) and U68.4 (The deficiency of yang in Bi), all codes were M codes (musculoskeletal system). 4. The M code (musculoskeletal system) was the most used major disease category in high-risk group, a total of 159 times. But in specific categories, the most commonly used code was R60.1 (systemic edema), a total of 28 times. 5. In normal group, the M code (musculoskeletal system) was the most used major disease category, a total of 84 times. Also, in specific categories, the most commonly used code was M25.57 (joint pain, ankle and foot), total 29 times. 6. The U code, corresponding to 'the diagnosis of childbirth and other obstetrical medical use', was used 23 times (6.71%), O code three times (0.87%) and Z code two times (0.58%), which was less than 10% of the total number of codes used. Conclusion: When analyzing KCD codes related to Korean medicine treatment for postpartum diseases, it is important to select the KCD codes that reflect the actual clinical state.
This study compared and analyzed the effect of the burden of household expenditure in the metropolitan and non-metropolitan areas on the intention to childbirth intention to married women using a panel logit model. To this end, this analysis targeted married women aged 25 to 39 who are highly likely to be fertile. The main results are as follows; First of all, it was confirmed that the economic power of spouse can be an important factor in the childbirth intention regardless of region. Second, it was found that the higher the satisfaction of marriage had a positive effect on the childbirth intention, and also higher the value that children must have, the higher the childbirth intention. Third, it was confirmed that the burden of household expenditure is the most important factor in the willingness to childbirth intention, excluding factors such as the number of existing children. In particular, the burden on education spending in both the capital region and non-capital region was found to be a key reason for the decrease in the childbirth intention. Lastly, the burden of household expenditure showed different effects on childbirth intention on depending on the region. Specifically, in the capital region, medical spending and loans had a greater impact, while, in the non-capital region, transportation and communication costs had a greater impact on childbirth intentions. Through the results, this study confirmed the implication that easing the burden on household expenditure is continuously necessary to enhance childbirth, and that discriminatory policy approaches are required depending on the area of residence.
Gestational trophoblastic disease (GTD) is a condition of uncertain etiology, choriocarcioma, or placental-site hydatidiform moles, invasive moles, choriocarcinoma, and placental-site trophoblastic tumors. It arises from the abnormal proliferation of trophoblastic tissue and spreads beyond the uterus hematogenously. The early diagnosis of GTD is important to ensure timely and successful management and the preservation of fertility. We report the unusual case of a metastatic choriocarcinoma that formed bullae on the lung surface and presented as recurrent pneumothorax in a 38-year-old woman with elevated beta-human chorionic gonadotropin (hCG) levels. She underwent thoracoscopic wedge resection of the involved lung and four subsequent cycles of consolidation chemotherapy. No other evidence of metastatic disease or recurrent pneumothorax was noted during 22 months of follow-up. GTD should be considered in the differential diagnosis of spontaneous pneumothorax in reproductive-age women with an antecedent pregnancy and abnormal beta-hCG levels.

Tropical tasar silkworm Antheraea mylitta Drury experiences extreme temperature stress conditions during its life cycle particularly during diapauses and first crop. The present study witnessed the impact of high temperature on some biochemical profiles and egg production (fecundity) of semi-domesticated Daba and Shorea robusta (Sal) based wild ecorace Laria during seed cocoon (pupa) preservation. Cocoons of Daba and Laria were treated with high temperature at $40^{\circ}C$ for 10 days in a BOD incubator. The protein profile and carbohydrate content in the hemolymph and fat body and total haemocyte count (THC) in the hemolymph of pupa were investigated. Further, the fecundity and fertility of egg was assessed. Significant increase in the protein concentration was observed in the hemolymph with reduction in the fat body (p<0.05). The difference in protein concentration was highly significant between the semidomesticated Daba and wild ecorace Laria (p<0.05). High pupal mortality (20%) and reduced fecundity (10-15%) in Daba was noticed compared to wild Laria. Also an increased THC (>28000) was recorded in Laria. The study infers the potentials of wild ecoraces in sustaining the extreme temperature conditions and need of adopting suitable package of practices for the preservation of diapause seed cocoons during extreme summer conditions. There is possibility to introgression thermal stress resistant traits in the semi-domesticated races of tasar silkworm by resorting to conventional breeding plans with wild races and keeping the thermal stress induced response as markers.
This paper investigates the effects of changes in household structure on service demand. The structure of households in Korea has been quickly changed due to low birth rate and population aging as well as increasing women's participation in the workforce. Their consumption patterns may have been altered by the structural changes. This paper focuses on the additional demand for market services replacing household activities such as household chores and care services. First, using a 3-sector time allocation model, we theoretically analyze the mechanism that marketization of household production can lead to the expansion of service industries. Next, in order to analyze the effects of changes in household structure on consumption demand, we estimate the Engel curves according to the QUAIDS model. For empirical work, the Survey of Household Finances was used. According to the results, structural changes in Korean households, such as an increase in single-person households, a decrease in families with a spouse or children under 6 years old, and an increase in dual-earner households, have caused an increase in medical expenses, education and training costs, and expenses for household services, which are typically substitutes for household production services.
In this study, we investigate the current status of family friendly management and determinants of its level. We choose measures about family friendly management and use their results from ESG evaluation model by Korea Corporate Governance Service. We find that firms with larger size, lower leverage and higher firm value are more family friendly. And in contrast to previous studies, firms are more family friendly when they have less women to total employees. But firms with higher largest shareholder holdings are less family friendly. These results show that listed firms in Korea should be more family friendly considering their level of woman employment. Also the interest and support from top management are needed for activating family friendly management, but largest shareholder of korean firms are not active yet.
Change in intracellular $Ca^{2+}$-concentration ($[Ca^{2+}]_i$) is an essential event for egg activation and further development. $Ca^{2+}$ ion is originated from intracellular $Ca^{2+}$-store via inositol 1,4,5-triphosphate receptor and/or $Ca^{2+}$ influx via $Ca^{2+}$ channel. This study was performed to investigate whether changes in $Ca^{2+}$/calmodulin dependent protein kinase II (CaM KII) activity affect $Ca^{2+}$ influx during artificial egg activation with ethanol using $Ca^{2+}$ monitoring system and whole-cell patch clamp technique. Under $Ca^{2+}$ ion-omitted condition, $Ca^{2+}$-oscillation was stopped within 30 min post microinjection of porcine sperm factor, and ethanol-induced $Ca^{2+}$ increase was reduced. To investigate the role of CaM KII known as an integrator of $Ca^{2+}$- oscillation during mammalian egg fertilization, CaM KII activity was tested with a specific inhibitor KN-93. In the eggs treated with KN-93, ethanol failed to induce egg activation. In addition, KN-93 inhibited inward $Ca^{2+}$ current ($I_{Ca}$) in a time-dependent manner in whole-cell configuration. Immunostaining data showed that the voltage-dependent $Ca^{2+}$ channels were distributed along the plasma membrane of mouse egg and 2-cell embryo. From these results, we suggest that $Ca^{2+}$ influx during fertilization might be controlled by CaM KII activity.
