Objectives: The purpose of this study was to investigate the association between sleep status and weight loss among adult women with obesity administered with Gamitaeeumjowee-tang. Methods: We retrospectively reviewed the medical records of 137 patients who were were administered with Gamitaeeumjowee-tang for 3 months for the purpose of weight loss. We divided subjects according to sleep duration and sleep quality. We conducted an independent t-test to compare the differences of weight loss between two groups. Also, a regression analysis was applied to determine which factors affected weight loss. Results: There was no significant difference in weight loss between patients who sleep more than 7 hours regularly and patients who sleep less than 7 hours. There was no significant difference between good sleepers and poor sleepers. Initial body mass index and the number of visits to the clinic were the significant factors in weight loss in 2-4 weeks. Initial weight loss was the significant factor in weight loss in 10-12 weeks. There was no significant correlation of sleep duration and sleep quality in weight loss in 2-4 weeks and 10-12 weeks. Conclusions: This study suggests that weight loss may not be affected by sleep status during Gamitaeeumjowee-tang intervention. ostachys japonicus, THP-1, acute myeloid leukemia, apoptosis, autophagy.

Objective: The relationship between water-holding capacity (WHC) and intermuscular fat (IMF) was studied in Japanese commercial pork. Methods: Longissimus muscles of pigs (n = 62), obtained from two meat packing plants, were analyzed for IMF content, moisture content, drip loss, cooking loss, and pH. Pairwise relationships among these traits were determined using correlation analyses. Results: IMF content was significantly correlated with moisture content (r = -0.88; p<0.01) and pH (r = 0.32; p<0.05), but not with drip loss (r = -0.23; p = 0.07) or cooking loss (r = -0.10; p = 0.42). In contrast, drip loss was significantly (and negatively) correlated with pH (r = -0.57; p<0.01). Conclusion: IMF content was not significantly correlated with WHC in pork, and so ultimately, we consider pH to be one of the most important factors influencing WHC in pork meat.

운동과 식이요법을 병행한 체중감량 프로그램에 참여한 여성 비만인의 체지방량, 안정시대사량, 그리고 갑상선 호르몬 차이를 비교할 목적으로 실험한 결과, 체지방량, 체지방율, 체표면적이 유의하게 감소되었고, 안정시대사량 예측치와 실측치 모두 유의하게 감소되었지만, 갑상선 호르몬의 변화는 나타나지 않았다. 안정시대사량과 신체요인들과의 상관분석 결과, 제지방 체충이 가장 밀접한 관계를 보였으며, 안정시대사량과 갑상선 호르몬들과의 관계에서는 TSH와 가장 밀접한 관계를 나타내었다. 결론적으로 8주간 체중감량 프로그램 참여로 체지방은 효과적으로 감소되었으나, 갑상선 호르몬 차이는 없었고 체중감소에 비해 제지방이 유지됨으로써 안정시대사량의 감소는 최소화되어, 에너지 대사작용에 긍정적인 영향을 준 것으로 사료된다.

본 논문에서는 일종의 멀티코드 시스템인 Binary CDMA의 성능을 향상시키기 위해 상관도 값을 평활화하는 방법을 제안한다. DS-CDMA 방식과는 달리, Binary CDMA 에서는 멀티레벨 신호를 이진 클리핑하여 전송하므로 선형성이 떨어지는 전력증폭기를 사용해도 무방하다. 그러나, 전송신호가 이진 클리핑되는 과정에서 각 채널사이의 직교성이 감소하여 수신부에서의 채널별 상관도 값은 랜덤해지며, 가장 작은 상관도 값을 갖는 채널에 의해 시스템의 평균 BER이 결정된다. 본 연구에서는 수신부 상관도 값이 불균형한 분포를 갖지 않고, 전 채널에 대해 고르게 분포하게 하는 상관도 평활화 방법을 적용하여 시스템의 평균 BER을 개선하였다. 여러 종류의 확산코드를 이용하여 실험한 결과, BER은 낮아지고 가용 채널의 수는 증가하였다.

The purpose of the this study was to research the interrelationship of periodontal status and patient's age between diabetic group and non-diabetic group and compare that of periodontal status according to the blood sugar level and duration of diabetics. The participants of this study were 52 diabetic patients and 51 non-diabetic patients. The diabetic group and non-diabetic group were further divided into four subgroups according to the age(under 35 years old, 36 - 45 years old, 46 - 55 years old, over 56 years old) and the diabetic group was further divided into three subgroups according to the duration of diabetics (under 5 years, 6 - 10 years, over 11 years) and blood sugar level(under 140mg/100ml, 140-200mg/100ml, over 200mg /100ml), respectively. Author evaluated such periodontal status as plaque index and calculus index, gingival lndex, loss of attachment, papillary bleeding index, tooth mobility and missing teeth, and then data was statistically analyzed by SPSS/PC+ using ANOVA, respectively. The results were as follows: 1. The mean value of plaque index, gingival index, loss of attachment, papillary bleeding index, tooth mobility and missing teeth of diabetic patients were significantly higher than that of non-diabetic patients, respectively(p <0.01, p<0.01, p<0.01, p<0.01, p<0.001, p<0.001), but there was no significant difference between diabetic group and non-diabetic group in calculus index(P>0.05). 2. According to the increase of age, loss of attachment and missing teeth were increased in both group, and correlation of each subgroup was statistically significant, respectively(p<0.05, p<0.001). 3. According to the elevation of blood sugar level of diabetics, plaque index, gingival index, loss of attachment, papillary bleeding index, tooth mobility and missing teeth were increased in diabetic group, and correlation of each subgroup was statistically significant, respectively (p<0.05, p<0.05, p<0.05, p<0.05, p<0.001, p<0.001). 4. According to the duration of diabetics, plaque index, gingival index, loss of attachment, papillary bleeding index, tooth mobility and missing teeth were increased in diabetic group, and correlation of each subgroup was statistically significant, respectively(p<0.05, p<0.05, p<0.05, p<0.05, p<0.001, p<0.001).

This study was performed to investigate the role of pH and temperature postmortem, and to demonstrate the importance of these factors in determining meat quality. Postmortem pH_45min (pH at 45 min postmortem or initial pH) via analysis of Pearson’s correlation showed high positive correlation with pH change pH_c24 (pH change from pH_45min to pH_24h postmortem). However, postmortem pH after 24 h (pH_24h or ultimate pH) had a high negative correlation with pH change, pH_c24, CIE L*, and protein content. Initial temperature postmortem (T_1h ) was positively associated with a change in temperature from 45 min to 24 h postmortem (T_c24) and cooking loss, but negatively correlated with water holding capacity. Temperature at 24 h postmortem (T_24h) was negatively associated with T_c24. Collectively, these results indicate that higher initial pH was associated with higher pH_c24, T_1h, and T_c24. However, higher initial pH was associated with a reduction in carcass weight, backfat thickness, CIE a* and b*, water holding capacity, collagen and fat content, drip loss, and cooking loss as well as decreased shear force. In contrast, CIE a* and b*, drip loss, cooking loss, and shear force in higher ultimate pH was showed by a similar pattern to higher initial pH, whereas pH_c24, carcass weight, backfat thickness, water holding capacity, fat content, moisture content, protein content, T_1h, T_24h, and T_c24 were exhibited by completely differential patterns (p<0.05). Therefore, we suggest that initial pH, ultimate pH, and temperatures postmortem are important factors in determining the meat quality of pork.

This paper presents a hardware-efficient auto-correlation scheme for the synchronization of MIMO-OFDM based wireless local area network (WLAN) systems, such as IEEE 802.11n. Carrier frequency offset (CFO) estimation for the frequency synchronization requires high complexity auto-correlation operations of many training symbols. In order to reduce the hardware complexity of the MIMO-OFDM synchronization, we propose an efficient correlation scheme based on time-multiplexing technique and the use of reduced samples while preserving the performance. Compared to a conventional architecture, the proposed architecture requires only 27% logic gates and 22% power consumption with acceptable BER performance loss.

A modified interfacial heat transfer correlation between a dispersed water droplet and ambient superheated steam is proposed and compared with available experimental data and other correlations. Modified one overcomes the inherent deficiencies of Lee and Ryley's interfacial heat transfer correlation that ignored the effects of steam superheating which can not be neglected especially in the reflood situation of a loss-of-coolant accident. Modified one is represented by (equation omitted) In the present correlation the effect of possible subcooling of a water droplet is not taken into consideration. Comparison of the above correlation with currently available measurement data for a water droplet in high temperature gas flow shows that the proposed one correlates well with the measurement data where the degree of superheating is negligible and considerable.

Purpose: The aim of this study was to investigate the impact of survivin expression and the decrease or loss of KAI-1 on the clinical stage and the survival rate in gastric adenocarcinomas. Materials and Methods: Expressions of survivin and KAI-1 were immunohistochemically determined in 40 cases of gastric adenocarcinomas. The survivin and KAI-1 expressions were also analyzed by using western blots in 14 cases among them. Results: Resected gastric cancer specimens from 40 patients (intestinal type: 15 cases and diffuse type: 25 cases) were evaluated immunohistochemically. Survivin protein expressions were significantly higher in diffuse types (P=0.03) and in advanced clinical stages (UICC TNM II and III, P=0.02). In contrast, a decrease or loss of KAI-1 expression had no statistically significant correlation with the Lauren classification or the clinical stage. Survivin protein positivity was associated with an unfavorable prognosis. Decrease or loss of KAI-1 was associated with a shorter disease free survivial rate (P < 0.01). The western blot data (n=14) indicated that neither survivin protein over-expression nor KAI-1 down-expression had an significant correlation with the Lauren classification or the clinical stage. Conclusion: In gastric carcinomas, survivin over-expression and decrease or loss of KAI-1 were associated with unfavorable prognosis, being independent prognostic factors along with the clinical stage and the disease free survival rate.
