The aim of this study was to determine the changes of body weight, organ weight, hematological values and biochemical parameters by testosterone (Testos) on the orchidectomized (Orch) rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. Orch group received operation and no treatment. Orch+Testos received operation and testosterone. The body weights of each group increased, but that of Orch+Testos group was significantly lower in Orch+Testos group than in all the other groups. There were significant differences (P<0.05, P<0.001) of body weights between Orch+Testos group and all the other groups. Also, organ weights such as heart, liver, spleen and kidney were measured. The heart weights were significantly lower (P<0.001) in the Orch+Testos group than in all the other groups. The liver weights in the Orch+Testos group were significantly differences in comparison with those in the Sham (P<0.001) and Orch group (P<0.05). On the other hand, there were no significantly differences in the organ weights of spleen and kidney between the Orch+Testos group and the any other groups. The hematological values of white blood cell (WBC), red blood cell (RBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were no significant differences in any other groups. The concentrations of serum total protein and albumin increased significantly (P<0.05) in the Orch+Testos group as compared to that in the Orch group. However, there were no significant differences in Ca, IP and Mg in any other groups. We conclude that testosterone was significantly decreased the body weight in the orchidectomized rats. Our findings suggest that testosterone may influence the process of lipid packaging and absorption in the orchidectomized rats.

기존의 연령별 얼굴정서 인식 비교 연구에서는 정서별로 연령 간에 어떤 차이가 있는지 밝혔다. 이에 Kim(2021) 연구에서는 개별 정서가 아닌 정서공간에서 표상된 정서를 연령 간 비교하였다는 점에서 의의가 있으나, 기술적(descriptive) 비교만 시행하였을 뿐, 통계적 유의미 검증을 하지 않았다는 한계가 있다. 본 연구에서는 표상 유사성 분석(representational similarity analysis) 방법을 통해 연령간 실제 데이터 및 정서 모델 유사성행렬을 직접적으로 비교하였다. 또한 개인차 다차원척도법(individual differences multidimensional scaling)을 통해 연령간 정서 차원에 대한 비중을 비교하였다. 그 결과 실제 데이터 비교에서 노년 집단은 청년 및 중년 집단과 가장 유사하지 않았으며, 쾌불쾌 차원이 포함된 정서 모델과의 유사성 비교에서도 가장 유사하지 않았다. 또한 노년 집단은 각성 차원에 대한 비중이 청년 및 중년 집단과 유사하지 않음이 발견되었다. 본 연구는 실제 데이터, 정서 모델, 그리고 정서 차원 비중이라는 세 가지 측정치에 대해 노년 집단과 청년 및 중년 집단과의 차이를 통계적으로 검증하였다는 점에서 의의가 있다.

This paper compares a cross-cultural and gender differences and similarities about consumer ethical perceptions and behaviors, and ethical ideologies between Korean and the US college students. It also examines the relationships between consumers' ethical perceptions and behaviors, and the relationships between consumer ethics and ethical ideologies. This research provides some evidence that supports the premise that consumer ethics is influenced to an extent by consumers' nationality and gender. The differences are not universal, however, and could perhaps be described as situational. The American college consumers were found to be more idealistic and relativistic than the Korean college consumers. But the differences were minor The American male college consumers were found to be more idealistic than the American female college consumers. The ethical consumer groups were found to be more idealistic and less relativistic than were the unethical consumer groups. Perceptions were positively related to behaviors in the consumer ethics. But the magnitude of impacts is different between the nations and in the dimensions of consumer ethics.

This study explores the effects of various factors on the use of nutrition information on food away from home (FAFH). Consumer groups were classified into groups according to their perception of being overweight and obese (correctly perceiving, underestimating and overestimating weight). For this, frequency analysis, a chi-square test, and an ANOVA were conducted to determine any differences between factors, and a logit analysis (SPSS 18.0) was conducted to identify those factors influencing the use of information. Information recognition, intentions to use information and the use on FAFH showed significant differences across the groups. In addition, health inspection, the perception of the intrinsic quality of restaurants, labeling, FAFH expenditure, and some individual characteristics showed significant differences between groups. The information recognition of FAFH had a significant positive effect on information use in all groups. In all groups, labeling had a significant positive effect on information use, and family health concerns had a significant positive effect on information use in the group correctly perceiving weight. The price of domestic food items, household head and household income had significant positive effects on information use in the group overestimating weight.

The effects of brisk walking & muscle strengthening exercise on pain, fatigue, physical function & disease activity were examined in 28 patients with rheumatoid arthritis. Research design was a quasi-experimental study of non-equivalent control group pretest-posttest design. 14 for the experimental group and 14 for the control group were selected from the out patients on rheumatoid arthritis clinic of Dong-A University Hospital. The experimental group underwent 16 weeks of brisk walking and muscle strengthening exercise using Thera-Band. Pain, fatigue, physical function & disease activity was measured before and after 16 weeks of exercise. At baseline test, Fatigue & physical function score between groups were significantly different. So differences with in experimental group(baseline versus follow up) were compared with differences within the control group by Mann-Whitney test. There were significant differences between groups in the difference score on pain (U=6.50 p<.001) and fatigue (U=26.5 p<.01). For the experimental group, the score on the pain & fatigue was significantly decreased but no changed for the control group. Also there was a significant differences between groups in the difference score of the physical function (U=22.5 p<.001). For the experimental group, the score of the physical function has been significantly in creased. However, for the control group, it has been no changed. But there were no significant differences between groups in the ESR (erythrocyte sedimentation rate) and the CRP (C-reactive protein)level. In summary, brisk walking & muscle strengthening exercise led to significant improvements in pain, fatigue, and physical function without exacerbating disease activity in patients with rheumatoid arthritis.

This study was undertaken to examine the extent to which tooth size and jaw size each contribute to dental crowding. Two groups of dental casts were selected on the basis of dental crowding. One group, consisting of 94 pairs of dental casts (46 males and 48 females) with normal occlusion. A second group, consisting of 84 pairs of dental casts (98 males and 46 females) with crowding. The results were as follows. 1. Means and standard deviations of the two groups were used to compare the two groups. 2. Significant differences were observed between two groups on the basis of tooth size, arch dimension and arch perimeter. 3. Between noncrowded group and crowded group, was crowded group was found to have large troth size than noncrowded group, while smaller arch dimension and perimeter. 4. Significant differences were observed between males and females on the basis of tooth size, arch dimension and arch perimeter. 5. Author found ideal arch shape of normal occlusion.

Dexterity is defined in the present study as interdigital manipulative skill or the fine manipulative movements of objects held between the thumb and fingers. The Grooved pegboard test has been used to evaluate dexterity requring visual-motor coordination. The purpose of this study was to standardize the completion time of the Grooved pegboard test in different age groups and gender. Normative values for the Grooved Pegboard Test was developed on the sample of 282 healthy volunteers (89 men and 183 women). Subjects were stratified according to gender and dominant hand and were subdivided into six groups by blocking. The results of this study were as follows: 1) There was a significant difference in completion time between dominant and nondominant hand in both men and women groups (p<.05). 2) There were significant differences in completion time between men and women group (p<.05) 3) There were significant differences in completion time among age groups (p<.05).

Objective : To evaluate the risk factors that may be responsible for the development of contralateral reherniations from ipsilateral ones after open lumbar microdiscectomy (OLM), and to compare surgical outcomes of revision OLM for contralateral reherniations with those for ipsilateral ones. Methods: Seventeen patients who underwent revision OLM for contralateral reherniation were enrolled into Group I, and 35 patients who underwent revision OLM for ipsilateral reherniation were enrolled into Group II. Using medical charts and imaging study results, the differences in the clinical and radiological factors were evaluated between the two groups. Clinical outcomes of each group were compared between the two groups. Results: Significant differences were found in the interval to reherniation from initial surgery (33 months for Group I and 18.6 months for Group II, p=0.009), as well as in the incidences of both protruded disc (35.3% for Group I and 8.6% for Group II, p=0.045) and mild disc degeneration (29.4% for Group I and 5.7% for Group II, p=0.031) at initial surgery. On binary multi-logistic regression analysis, significant differences were found in the interval to reherniation (p=0.027, Odds ratio=1.051) and incidence of mild disc degeneration (p=0.025, Odds ratio= 12.03) between the two groups. There were no significant differences in the improvement of clinical outcomes after revision OLM between the two groups. Conclusion: The interval to reherniation from initial surgery and the grade of disc degeneration at initial surgery were key factors that distinguished the development of contralateral reherniations from ipsilateral ones. Surgical outcomes of revision OLM were similar in both groups.

Background: Thera-Band, Narrow squats, Kinesiology taping helps in the reduction of loading on the knee joints. Despite the fact that the varus knee negatively affects the alignment of the lower extremities, most of the studies have analyzed each independently. Objectives: To investigate the effects of a complex exercise program consisting of elastic band exercises and squat exercises on the distance between the inner knees and balance in young adults with genu varum. Design: A cluster randomized controlled trial. Methods: The complex exercise group performed resistance exercises using an elastic band. The taping group used kinesiology tape on the vastus lateralis and biceps femoris. To select those to be included in the study, we measured the distance between the knees using digital Vernier calipers and to measure the balance ability, we used a balance training system. The data were analyzed with the independent t-test and paired t-test. Results: The study indicated a significant difference in the distance between the knees between the two groups, but no significant differences in the dynamic balance between the groups. Also, the static balance comparison between the groups according to the intervention method included the trace length, C90 area, C90 angle and velocity. There were no significant differences in the static balance between the groups. In addition, the complex exercise program was more effective than taping. Conclusion: The results of this study demonstrate that the complex exercise program and taping decrease the between both the knee and increase the balance.
