The purpose of this study was to analyze whether seawater has positive effects on appearance characteristics, such as CIE a^*, and to determine the gas composition concentration that is suitable for maintaining it. Pork hind meat was cured with four types of curing agent for 5 d at 4℃. The different curing agents comprised the control salt, control nitrite pickling salt (CN), treatment brine, and treatment bittern (BT). The cured hams were cooked at 65℃ for 4 h and packaged at O₂:N₂ gas ratios of 7:3, 8:2, and 9:1 for 3 wk. The physicochemical properties were assessed immediately after heating the sample, and the color properties were measured after a 3 wk storage period. Based on the correlation results of the physicochemical properties, BT had a higher curing and cooking yield than the other treatments, owing to its high salinity. Results of color properties for BT (7:3) and CN (8:2) showed similar color CIE L^*, CIE a^* chroma, and hue angle values. Therefore, BT can be said to be a sous-vide curing agent suitable for preserving the color of ham, and a high nitrogen concentration of 30% helps to maintain the appearance of seawater sous-vide ham.

Objective : Several reports have found abnormal levels of androgen in post-traumatic stress disorder (PTSD) patients. This abnormality in androgen is hypothesized to due to chronic psychological stress effects on the hypothalamic-pituitary-gonadal (HPG) system. The present study was conducted to estimate serum testosterone levels in PTSD patients in comparison with normal subjects. Methods : Seventy-five male Korean veterans of the Vietnam War volunteered for the study, of which eleven were excluded because of incomplete psychological assessment. To measure basal serum testosterone, blood samples were collected between 8.00 and 9.30 a.m. The clinician administered PTSD scale (CAPS), the structured clinical interview for DSM-IV (SCID), Hamilton Anxiety Rating Scale (HAM-A), Hamilton Rating Scale for Depression (HAM-D), Mini International Neuropsychiatric Interview Plus (Korean version of MINI-Plus), CES-K (Korean version of combat exposure scale). Results : The serum testosterone level of PTSD patients ($5.4{\pm}2.5ng/mL$) was higher than that of a control group ($3.1{\pm}1.7ng/mL$, p<0.001). Testosterone levels were significantly correlated with CAPS (r=.38, p<.01), HAM-A (r=.35, p<.01) and HAM-D (r=.28, p<.01) in all subjects. Conclusion : The results of the present study suggest that chronic psychological stress affects the HPG system.

The objective of this study was to investigate the effects of mixed starter cultures isolated from kimchi on physicochemical properties, functionality and flavors of fermented ham. Physicochemical properties, microbial counts, shear force, cholesterol contents and volatile compounds of fermented ham were investigated during processing (curing and ripening time). Curing process for 7 d increased saltiness, however, decreased hunter color values (L, a, and b values). Ripening process for 21 d increased most parameters, such as saltiness, color values, weight loss, shear force and cholesterol content due to the drying process. The mixed starter culture had higher lactic acid bacteria than the commercial one. While eight volatile compounds were identified from fermented hams during curing process, total fiftyeight volatile compounds were identified from fermented hams during ripening process. The main volatile compounds were alcohols, esters and furans. However, no differences in volatile compounds were observed between two batches. Fermented hams (batch B) manufactured with probiotic starter culture (LPP) had higher sensory score in texture, color and overall acceptability than counterparts (batch A), while the opposite trend was observed in flavor. Therefore, mixed probiotic starter culture isolated from kimchi might be used as a starter culture to be able to replace with commercial starter culture (LK-30 plus) for the manufacture of fermented ham.

We designed a low cost optical structure of transflective LCD that uses only a half number of retardation films compared to general active matrix transflective LCD. The prototype embodied by this design shows reasonable reflective and transmissive performance. This design would provide us thinner, lighter and cheaper product due to its reduced retardation film structure.

On the half area of a pixel, pretilt angle was decreased by UV radiation and two domain TN was induced by the pretilt difference. In this structure, ITO slit was made inside pixel electrode on the TFT substrate to stabilize domain boundaries. The result shows that this structure is more resistant to outside stress and unwanted domain deformation is prevented.

목 적 : 가정폭력에 노출된 여성은 우울증, 불안장애, 외상 후 스트레스 장애 등 다양한 정신 질환에 이환되기 쉽다. 심박변이도 검사는 자율신경계의 활성도와 균형을 평가하는 검사로 비침습적이고 재현성이 높아 정신 질환에 대한 연구에서도 폭넓게 활용되고 있다. 그러나 폭력 피해 여성에 대한 심박변이도 연구는 아직까지 부족한 실정이다. 본 연구는 국내 폭력 피해 여성의 인구사회학적 특징 및 심리학적 특징을 살펴보고, 한국인과 외국인 폭력 피해 여성의 임상적 특징과 심박변이도 검사 결과의 차이를 비교해보고자 하였다. 방 법 : 여성쉼터에 입소한 폭력피해 여성 중 2011년 12월 부터 2015년 12월까지 건강검진을 위해 서울의료원에 방문한 대상자 중 한국인 166명, 외국인 44명, 총 210명 대상으로 HAM-D, HAM-A, IES-R 등 임상 척도 평가와 심박변이도 검사를 실시하였다. 폭력 피해 여성 중 한국인과 외국인의 인구사회학적 특징, 심리적 특징, 심박변이도를 비교하기 위하여 카이제곱 검정 및독립 표본 t-검정 등을 시행하였다. 결 과 : 한국인과 외국인 폭력 피해 여성은 거주지, 유년시절폭력의 경험, 폭력의 지속기간에서 유의한 차이가 있었다. 한국인과 외국인 폭력 피해 여성 두 군 간의 HAM-A, HAM-D, IES-R 점수에는 유의한 차이가 없었다. 심박변이도의 세부지표에서는 ApEn 수치가 외국인 폭력 피해 여성군이 한국인보다 유의하게 높았고, RMSSD 수치는 외국인 폭력 피해 여성 군이 한국인보다 유의하게 낮은 결과를 보였다. 기타 HRV 세부지표에서는 한국인 폭력 피해 여성 군과 외국인 폭력피해 여성 군 두 군 간에 유의한 차이를 보이지 않았다. 결 론 : 국내 폭력 피해 여성은 우울, 불안, 외상 후 스트레스장애 증상을 가지고 있는 비율이 높았고 한국인과 외국인 간의 차이는 유의하지 않았다. 그러나 심박변이도 검사에서 외국인의 ApEn 값이 유의하게 높고 RMSSD 값이 유의하게 낮았다. 이는 한국인과 외국인의 인종 생리적 또는 이민 생활 등 환경적 영향의 차이일 수 있으며 향후 충분한 수의 외국인 대상자와 한국인을 비교, 추적조사를 통하여 요인간의 인과관계를 파악하는 연구가 필요할 것으로 보인다.
