A field experiment was conducted to determine the optimal transplanting date for ‘Sukwang’, a high grain quality japonica rice, in the southwestern plain area in South Korea. 25-day-old seedlings were transplanted four times by 15 days interval on May 16, June 1, 16, and 30 in 2013 and 2014. Heading dates were August 12 and August 29 in the first and the last transplanting, respectively. Ripening ratio was highest in June 1 and June 16 plots at range of 93 - 94%, and was lowest in 16 May plot. Milled rice yield was the highest in June 1 and June 16 at rage of 538 - 555 kg/10a, and was the lowest in May 16. Head rice yield showed same tendency to milled rice yield. Protein content was not significantly different among treatments except June 1, however, it was slightly increased in the later transplanting plots. Amylose content was increased in the later transplanting plots. According to the regression curve of transplanting dates and grain yield, the optimal transplanting date of ‘Sukwang’ was June 10 in the southwestern plain area in Korea.

Testicular regression syndrome is representative of a clinical range of 46,XY agonadal persons, in which the testes of the victim`s are irreparably damaged at a critical stage in fetal development. The critical stage of testicular regression syndrome is represented by a range of abnormalities of genital development. Recently, we experienced a case of early fetal testicular regression syndrome with no definite gonad and a cloacal anomaly associated with imperforate anus, so we present it with brief review of literature.

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.

<P>Recently, the American Diabetes Association (ADA) has included glycated hemoglobin A1(c) (A1C) level as a component of diagnostic criteria of 'diabetes' or 'increased risk for diabetes'. This study was conducted to examine the prevalence of and risk factors for 'elevated A1C' (5.7%) in women with polycystic ovary syndrome (PCOS).</P>

Objective: To investigate: the prevalence of vitamin D deficiency in Korean women with polycystic ovary syndrome (PCOS), and the relationship between vitamin D status and clinical or metabolic features in this group. Methods: We recruited 38 women with PCOS using the Rotterdam criteria. A total of 109 premenopausal control women were matched with patients based on age and body mass index. Serum 25-hydroxy vitamin D concentrations less than 20 ng/mL were classified as frank vitamin D deficiency. Since vitamin D may play a significant role in metabolic disturbances in women with PCOS, correlations between clinical or metabolic parameters and vitamin D status were analyzed separately in patients and controls. Results: Women with PCOS showed no differences in the level of 25-hydroxy vitamin D ($19.6{\pm}6.6ng/mL$ in patients vs. $20.1{\pm}7.4ng/mL$ in controls, respectively, p=0.696) or prevalence of vitamin D deficiency (57.9% in patients vs. 56.5% in controls, respectively, p=0.880). In addition, we did not find any correlations between serum vitamin D level and clinical or metabolic profiles in either PCOS patients or controls. Conclusion: Our study found no differences in the absolute level of serum vitamin D between PCOS patients and matched controls. Prevalence of vitamin D deficiency was equally common among both patients and controls. Additionally, we did not find any correlations between serum vitamin D level and clinical or metabolic profiles, suggesting that the role of vitamin D in the pathogenesis of PCOS is not yet clear.

Objective: Metabolic disturbances are well-recognized clinical features of polycystic ovary syndrome (PCOS). Carotid intima-media thickness (CIMT) has been widely used as a surrogate marker of atherosclerosis and cardiovascular disease (CVD). CIMT in women with PCOS has been investigated in many studies, but there has been only one report in the Korean population. The aim of the present study was to compare the presence of subclinical atherosclerosis in young untreated Korean women with PCOS and age-matched controls, specifically by measuring their CIMT. Methods; CIMT was measured by one radiologist in 56 PCOS patients and 56 controls. To compare the CIMT according to PCOS phenotypes, women with PCOS were divided into two subgroups according to the presence of hyperandrogenism. Results; Although PCOS patients were more obese and had higher blood pressure and insulin resistance index than the age-matched controls, the CIMT was not different between the two groups (0.49 ± 0.09 mm in PCOS patients vs. 0.50 ± 0.11 mm in controls, respectively, p = 0.562). When the CIMT in the control group was compared with hyperandrogenic and non-hyperandrogenic PCOS groups, also no significant differences were found. Conclusion; Despite the significant differences in some vascular risk factors between women with PCOS and controls, PCOS patients did not have a significantly higher CIMT (even in the hyperandrogenic subgroups). Although our study did not show the increased risk of subclinical atherosclerosis in PCOS patients, the role of CIMT continues to be investigated considering the importance of screening and monitoring CVD risk factors in women with PCOS.

농약은 농작물이 잡초나 해충, 세균으로부터 받는 피해를 예방하고 농작물의 생산성 증진 등으로 농업에서 중요한 역할을 하는 농자재이다. 친환경 인증 농산물 외 일반 농산물은 허용기준 이내라도 농약이 잔류할 가능성이 있어 소비자들은 농산물 섭취 시 잔류농약 노출에 불안감을 갖고 있다. 이러한 불안감을 줄이기 위하여 과일에 잔류하는 농약을 효과적으로 제거하는 방법을 규명하기 위한 연구를 진행하였다. 본 실험은 친환경 사과를 처리구당 3개씩 3반복으로 나뉘어 살균제(Carbendazim, Trifloxystrobin), 살충제(Acetamiprid, Diflubenzuron)를 살포한 후, 7일 후에 무처리, 껍질 제거(제거), 물 세척(세척), 물 침지 후 세척(침지), 식초물 침지 후 세척(식초), 소다물 침지 후 세척(소다)의 방법으로 처리한 후 잔류농약을 분석하였다. 침지시간은 5분, 세척시간은 20초로 하였다. 잔류농약 분석을 위한 전처리는 균질화 된 시료 10 g을 50 mL 원심분리관에 칭량하여 Acetonitrile을 10 mL 주가한 후 1분간 진탕하고, 4 g MgSO<sub>4</sub>, 1g NaCl, 1g NaCitrate, 0.5 g Disodium citrate sesquihydrate를 첨가한 후 다시 1분간 균질기로 진탕한 다음 3,000 rpm/min으로 5분간 원심분리를 진행하였다. 상등액 1ml를 Dispersive SPE(25mg PSA, 150 mg MgSO4) tube에 넣고 1분간 진탕하고, 10,000 rpm에서 1분간 원심분리하여 상등액을 0.2 μm 시린지 필터로 여과하여 LC/MS/MS, GC/MS/MS 분석시액으로 사용하였다. 분석방법은 「농산물 잔류농약 다성분 분석방법」에 따라 4가지 농약성분을 분석하였다. 분석 결과 Carbendazim(살균제)은 무처리 대비 제거 88%>소다 72%>침지 64%>식초 61%>세척 55% 순으로 제거되는 결과를 나타냈다. Trifloxystrobin(살균제)은 제거 87%>소다 79%>식초 75%>세척 63%>침지 60% 순으로 제거되었다. Acetamiprid(살충제)는 무처리 대비 제거 91%>식초 63%>소다 59%>침지 50%>세척 47% 순으로 제거되는 결과를 나타냈다. Diflubenzuron(살충제)은 소다 87% >제거 80%>침지 78%>세척 76%>식초 67% 순으로 제거되었다. 4가지 성분 모두 껍질을 제거한 방법에서 잔류농약이 효과적으로 제거되었다. 세척에 따른 결과는 소다침지 후 세척이 Acetamiprid 외 3가지 농약에서 제거효과가 가장 좋았다. 농약성분 별로 처리방법에 따른 제거효과가 다른 결과에 대하여서는 추가적인 연구가 필요할 것으로 사료되었다.
