Objectives : Spontaneous intracerebral hemorrhage(S-ICH) is generally considered to be a mon-ophasic event. But some patients with ICH continued to bleed even after hospitalization. In order to evaluate the rebleeding and growth factor of hematoma in small volume S-ICH, 125 cases of S-ICH were reviewed retrospectively. Methods : We assesed age, sex, initial mental state, location of hemorrhage, systolic and diastolic blood pressure, blood pressure patterns, hematologic profile, trauma and stroke history, alcohol consumption and smoking history. Two subgroups-rebleeding groups versus no rebleeding groups-were compared, in terms of data analysis, with student T-test and chi-square test. Results : Substantial growth in the volume of S-ICH occurred in 21 cases(16.8%)-putamen(7 cases), thalamus(6 cases), subcortex(5 cases), cerebellum(2 cases), pons(1 case)-of the 125 patients. There was no significant difference in any of the parameters except initial systolic blood pressure(p=0.037) when patients with and without rebleeding were compared. Conclusion : The rebleeding and growth of the small volume S-ICH was related to the markedly elevated initial systolic blood pressure(${\geq}180mmHg$) and labile pattern of blood pressure.

Consumption of vegetables and fruits is associated with a reduced risk of stroke, but it is unclear whether their protective effects are due to antioxidant vitamins or folate and metabolically related B vitamins. The purpose of the study was to test the hypothesis that intake of fruits and vegetables, which are major sources of antioxidant and vitamin B complex vitamins, reduces the risk of stroke. Cases consisted of patients diagnosed with first event of stroke (n = 69). Controls (n = 69) were age-, sex-, and body mass index-matched to cases. Multivariable-adjusted regression analysis showed that subjects who ate four to six servings of vegetable per day had a 32% reduction in the risk of stroke, and those with more than six servings per day had a reduction of 69% after adjusting for age, sex, BMI, and family history of stroke. Intakes of total fat, plant fat, calcium, potassium, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, and folate were significantly and negatively associated with the risk of stroke. Although the trend was not significant, stroke risk was reduced in the second quartile (1.21-2.66 servings per week) of fish intake. However, intake of fruits (average daily intake of 1.0 serving) and antioxidant vitamins such as carotene, vitamin C, and vitamin E was not associated with the risk of stroke. In conclusion, our observational study suggests that intake of fat and vegetables, rich sources of vitamin B complex, calcium, and potassium may protect against stroke.

Objectives: The present study reports case of an advanced gastric cancer patient who did not receive resection and was treated with Korean Medicine (KM) monotherapy. Methods: A 59-year-old female patient diagnosed with advanced gastric cancer visited the Dunsan Korean medicine Hospital of Daejeon University on April 15, 2018 for the Korean medicine treatment. The patient was treated with KM for approximately 1 year, from May, 2018 to May, 2019. Computed tomography (CT) was used to follow-up of the tumor site. Laboratory analysis and National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), version 5.0 were used to evaluate the safety of our treatment. Results: The patient's quality of life (QOL) and related symptoms improved during the treatment. Conclusion: This study suggests that KM may help to improve QOL of advanced gastric cancer patients. This is a valuable report that shows the natural history of Korean gastric cancer invasion to deeper layers over time.

An evaluation is presented of the response of a 3-storey R/C structure during the destructive Lefkada earthquake of 14/08/2003. Key aspects of the event include: (1) the unusually strong levels of ground motion (PGA = 0.48 g, $SA_{max}$ = 2.2 g) recorded approximately 10 km from fault, in downtown Lefkada; (2) the surprisingly low structural damage in the area; (3) the very soft soil conditions ($V_{s,max}$ = 150 m/s). Structural, geotechnical and seismological aspects of the earthquake are discussed. The study focuses on a 3-storey building, an elongated structure of rectangular plan supported on strip footings, that suffered severe column damage in the longitudinal direction, yet minor damage in the transverse one. Detailed spectral and time-history analyses highlight the interplay of soil, foundation and superstructure in modifying seismic demand in the two orthogonal directions of the building. It is shown that soil-structure interaction may affect inelastic seismic response and alter the dynamic behavior even for relatively flexible systems such as the structure at hand.

Purpose: Many studies have examined the mechanisms of impaired glucose homeostasis after organophosphate (OP) exposure, however no study has evaluated the clinical utility of blood glucose measurements in patients with OP poisoning. The current study was conducted to evaluate the initial glucose level at presentation and the glycemic variables during the first 3 days after admission as a predictor of mortality. Methods: This retrospective observational case series included 228 patients with a history of OP poisoning. Among other clinical data, information on the initial glucose level at presentation and mean glucose level, delta glucose level, and the presence of a hypoglycemic event during the first 3 days of admission, was collected. Results: Survivors had lower initial glucose levels at presentation and glucose variability during the first 3 days of admission compared to non-survivors. The frequency of hypoglycemic events was higher in non-survivors. In multivariate analysis, the initial glucose level (> 233 mg/dl) was an independent predictor of mortality, along with age. Conclusion: The initial glucose level at presentation can be helpful in prediction of mortality in cases of OP intoxication at bedside. The physician should pay attention to patients with a glucose level >233 mg/dl at presentation after ingestion of OP.

Purpose: The purpose of this study is to provide basic data to improve prehospital emergency care for patients with labor pain, vaginal bleeding and rape experience by analyzing the reports of 119 emergency medical technicians. Methods: Data were prehospital reports of 190 patients having chief complaints of labor pain, vaginal bleeding and rape in Chungcheongnam-do from January 1, 2012 to December 31, 2012. Data were analyzed using SPSS 21.0 descriptive statistics and $x^2$-test. Results: From the 190 cases of labor pain, vaginal bleeding and rape, labor pain accounted for 57.9% including 75.5% of normal delivery; vaginal bleeding accounted for 35.8% including 26.5% of postpartum hemorrhage; and rape victims accounted for 6.3%. Cases with more than one vital sign accounted for 94.2%, but cases without primary assessment of the obstetrics and gynaecology accounted for 38.4% from gestation weeks, 78.0% from parity, and 87.4% from history taking relating to event. Patient care including emotional support was the first priority care accounted for 78.4% and 60% of care was keeping the patients warm. Conclusion : In order to handle various emergency situations properly, the records must be supplemented by obstetrical and gynaecological rape checklist and rape victims supporting system should be established.

The DYLAM-3 code which overcomes the limitation of event tree/fault tree was applied to LOOP (Loss of Off-site Power) in the mid-loop operation employing HEPs (Human Error Probabilities) supplied by the ASEP (Accident Sequence Evaluation Program) and the SEPLOT (Systematic Evaluation Procedure for Low power/shutdown Operation Task) procedure in this study. Thus the time history of core uncovery frequency during the mid-loop operation was obtained. The sensitivity calculations in the operator's actions to prevent core uncovery under LOOP in the mid-loop operation were carried out. The analysis using the time dependent HEP was performed on the primary feed & bleed which has the most significant effect on core uncovery frequency. As the result, the increment of frequency is shown after 200 minutes duration of simulation conditions. This signifies the possibility of increment in risk after 200 minutes. The primary feed & bleed showed the greatest impact on core uncovery frequency and the recovery of the SCS (Shutdown Cooling System) showed the least impact. Therefore the efforts should be taken on the primary feed & bleed to reduce the core uncovery frequency in the mid-loop operation. And the capability of DYLAM-3 in applying to the time dependent concerns could be demonstrated.

Due to the imbalanced vibration of the adjacent buildings, the pounding phenomenon occurs as a result of an insufficient gap between them. Providing enough gap between adjacent structures is the most efficient approach to preventing the pounding effect. This paper calculated the required separation gaps between adjacent buildings, including two, four, eight, twelve and twenty stories steel moment-resisting frames, and investigated their related influencing parameters such as time periods, damping ratios, and the number of bays. The linear and nonlinear dynamic time-history analyses under real seismic event records were conducted to calculate the required separation gaps by obtaining relative displacement and velocity functions of two adjacent frames. The results showed that the required separation gap increased when the time periods of adjacent frames were not the same. The resulting separation gaps values of linear and nonlinear analyses were similar only for two and four stories frames. In other frames, the resulting separation gap values of linear analyses surpassed the corresponding nonlinear analyses. Although increasing the damping ratios in adjacent frames causes a decrease in the required separation gaps, the number of bays had no significant effect on them.

노동시장에서 성별직업분리의 연속성을 설명하는 주요한 논의들은 여성들의 직업선택에 성역할분화가 뿌리깊은 영향을 미치고 있음을 지적하고 있다. 즉, 여성들은 어머니로서의 역할을 보다 수월하게 병행할 수 있는 직업--그것이 모성역할에 보다 호의적이건, 또는 노동시장의 진입과 이탈에 보다 우호적이건--을 선택하는 경향이 강하다는 것이다. 그리고 이러한 여성들의 자녀양육의 책임에 따른 직업선택이 결과적으로 성별직업분리를 영속화시키는 주요한 원인이라는 점을 강조하고 있다. 이러한 이론적, 경험적 논의를 바탕으로, 여성들의 임신과 자녀양육의 영향에 초점을 두고 본 연구는 성별 직업분리가 여성들의 직업연속성에 미치는 효과를 분석한다. 본 연구는 미국의 National Longitudinal Survey of Youth (NLSY) 1979-1998 데이터를 이용하여 시간연속적 사건사 분석 방법(continuous time event history models)을 적용하여 여성들이 직업을 이탈하는 다양한 유형과 과정을 분석한다. 본 연구결과에 따르면 여성직종에 근무하는 여성들은 비 여성직종에 근무하는 여성들보다 직업을 이탈할 가능성이 더 낮은 것으로 나타났다. 더욱이, 이러한 직업분리도와 여성직업 연속성의 관계는 여성의 자녀양육에 의해 영향을 받지 않는 것으로 나타났다. 자녀를 둔, 또는 임신한 여성들이 직장을 떠날 가능성은 더 많지만, 여성직종에 근무하는 여성들은 비 여성직종에 근무하는 여성들보다 노동시장을 완전히 이탈할 가능성은 오히려 낮은 것으로 본 연구결과는 나타내고 있다. 이러한 결과는 기존의 이론적 논쟁점 여성들의 여성직종 선택은 여성성의 표현이고 그들의 모성역할을 수행하기 위하여 전략적으로 여성직종을 선택한다는 것과 일치하지 않는 것이다. 결론적으로 본 연구결과는 성별 직종분리가 임신과 육아책임을 수행하기 위한 여성의 경제적 합리성에 근거한 자발적 선택이라는 이론적 논의는 다시 고찰되어야 한다는 점을 강조한다. 것으로 판정되었다.때문에 오히려 낮은 파괴강도를 보였다. 경도는 입계에 존재하는 coalesced Mo 입자들과 matrix의 입성장 때문에 더욱 감소하였으나 반면에 파괴인성은 더욱 증가하는 경 향을 보였다.과 향을 적당하게 평가함으로써 전반적인 기호도에서 가장 좋게 평가된 것으로 사료된다. 또한 23시간의 가열 농축은 31시간에 비해 경제적인 면에서도 바람직할 것으로 사료된다. 결론적으로 떫은감을 가열 농축하여 제조한 23시간 농축액은 자연적인 강한 단맛을 제공할 수 있고 동시에 항산화성과 탄닌성분을 많이 함유함으로써 식품조리와 식품가공에 유용하게 활용될 수 있을 것으로 사료된다. 가졌으며 이는 Silymarin(93%) 보다도 우수하였다. 2종의 박하 추출물 투여군들 사이에는 혈청 GPT 활성에 대한 유의적인 차이가 나타나지 않았다. 7.과산화물질 (TBARS)의 함량은 정상군에 비해 음성대조군에서 약간의 함량 증가가 관찰되었으나 유의적인 수준은 아니었으며 대부분의 박하 추출물 투여군과 Silymarin 투여군에서 과산화지질이 비슷한 수준으로 증가하여 박하는 알콜에 의한 과간화지질생성에 대한 저해효과가 낮은 것으로 확인되었다. 8. 상대간장중량은 각 실험군별로 상대간장중량에서의 차이는 다소 있었으나 유의성은 없었다.mg/ml로 한 EtOAc 분획물은 26의 돌연변이 유발성을 보였다. 이상의 결과로 부터 뽕나무를 이용한 식용 제품생산을 고려할 때 추출물들의 제조와 선택을 가름하는 자료로서의 활용이 기대되며 앞으로 in vivo test 등 더욱 연구할 필요가 있을 것으로 사료된다.0^{-4}\;pg/cell$로 60 kHz로 병행 추출한 복분자 water 분획층의 $19.5{\times}10^{-4}\;pg/cell$보다 높은 분비량을 나타내었다. 당귀와 마황에서도 40 kHz의 초음파로 병행 추출한 것이 더 높은 분비량을 나타내었다.
