Background: Adults with forward head posture (FHP) often suffer from thoracic hyperkyphosis and thoracic dysfunction, and including reduction of the craniovertebral angle (CV angle) and tightening of the superficial neck muscles. In order to treat thoracic dysfunction, interventions aimed at improving thoracic mobility are necessary. Objectives: To examine the effects of maitland manual mobilization therapy on the thoracic spine in adults with FHP. Design: Single-blind randomized controlled trial. Methods: Thirty adults with FHP who met the selection criteria were randomized to the thoracic multiple joint mobilization (TMJM; n=15) group and the thoracic general joint mobilization (TGJM; n=15) group. Joint mobilizations were performed for 23 minutes a day for 4 weeks continuously, two times per week. Outcome measures were ImageJ, BTS FREE EMG 1000, neck disability Index (NDI). Results: Although changes in the left sternocleidomastoid muscle activity and NDI scores over time between the two groups differed, other variables were noted only changes observed over time. Muscle activity in the right sternocleidomastoid increased again in the TGJM group post-intervention and 2 weeks after the end of the experiment, but changes in other variables were retained or improved, confirming the lasting effects of thoracic joint mobilization. Conclusion: Thoracic multiple joint mobilization may be recommended as a more effective intervention for adults with FHP.

Background: For generations, cigarette smoking has presented an important public health concern. This study aimed to compare the health-promoting behavior, exercise capacity, physical activity level, health literacy, and knowledge level of smoking-related diseases between smokers and non-smokers. Methods: The study included 71 smokers (mean age, 32.69±8.55 years) and 72 non-smokers (mean age, 31.88±9.94 years) between the ages of 20 and 60 years. Assessments included a 6-minute walking test (6MWT), Godin Leisure-Time Physical Activity Questionnaire, Health-Promoting Lifestyle Profile II (HPLP-II), Cardiovascular Risk Factors Knowledge Level Scale (CARRF-KL), Asthma/COPD Awareness Questionnaire, the World Health Organization Quality of Life-Bref questionnaire (WHOQoL-Bref [TR]), and Health Literacy Questionnaire (HLQ). Results: The results from the study show that the number of coronary artery disease risk factors measured significantly higher among the smoker group members when compared to that of the non-smoker group members (p=0.001). Smokers had significantly lower %6MWT distance than non-smokers (84.83±4.72 and 93.45±7.16, respectively; p<0.05). However, there were no significant differences between the smokers and non-smokers in terms of physical activity, CARRF-KL, HLQ, WHOQoL-Bref, and HPLP-II subscales or total scores (p>0.05). Additionally, while only forty-one smokers (57.7%) were active, 48 of the non-smoker group was active (66.7%). Conclusion: Smokers suffer greater negative effects to their exercise capacity in comparison to non-smokers. Although smokers and non-smokers have similar levels of health literacy and similar levels of knowledge about cardiovascular disease risk factors and obstructive lung diseases, health professionals could continue to further increase individuals' awareness of smoking-related risk factors and continue to emphasize the importance of physical activity and exercise for protecting cardiopulmonary health.

This study was carried out to investigate the effectiveness of active biotelemetry to monitor stress response, and the effects of acute stressor (raising a hind foot of a standing animal) on body temperature (BT) and heart rate (HR) in comparison heifer group (n=4) with cow group (n=3). Both parameters were recorded by active telemetry. Cortisol assay was used to compare the result of active biotelemetry. The stressor consisted in restraining the cows for hoof treatments. Body temperature and heart rate were measured at 0, 10, 20, 30, 40, 50, 60, 90, 120, 180 and 360 minutes during the experiments, and also cortisol assay at 0, 0.5, 1, 2, 3, 12 and 24 hours. Base line for these animals was set in there accustomed environment at -24hrs and -30 mins before the beginning of experiments. The results obtained in this study were as follows: 1. In the BT, heifer group showed no significant difference from cow group, but were observed slightly higher BT than cow group during restraint stress for 30 minutes. 2. The both groups showed directly significant increase of HR immediately after the beginning of the restraint stress (P<0.01), but in the required time for the recovery of HR after finishing the stress, heifer group was 40 minutes and cow group 60 minutes. 3. In the cortisol assay, the both groups increased from 30 to 120 minutes after the beginning of experiment (i.e, from 0 to 90 minutes after finishing the restraint stress), showing significant difference from before the beginning of the stress (P<0.01), but heifer group showed great increase of the cortisol level from 30 to 60 minutes after the beginning of the stress, while cow group was observed at 60 minutes. In conclusion, we suppose that care is required to decrease psychological stress in cattle when they suffer from a series of procedures for diagnosis and treatment, especially in heifers rather than in cows. Also BT and HR obtained by active biotelemetry are reliable indicators of stress in cattle.

Purpose: To investigate the efficacy and safety of Javanica oil emulsion injection (Yadanzi$^{(R)}$) combined with pemetrexed and platinum (PP) for treating patients with advanced lung cancer. Patients and Methods: From June 2011 to June 2013, we recruited 58 patients with advanced lung cancer, and divided them into two groups. Twenty eight patients received Yadanzi$^{(R)}$ (from ZheJiang Jiuxu Pharmaceutical Co., Ltd.) together with PP chemotherapy (combined group), while the others were given only PP chemotherapy (control group). After two cycles of treatment, efficacy and safety of treatment were evaluated. Results: The overall respnse rate [(CR+PR+SD)/(CR+PR+SD+PD)] of the combined group was higher than that of control group (89.7% vs. 86.2%, p>0.05). Regarding rate of life improvement, it was 82.8% in combined group, and 51.7% in the control group (p<0.05). In terms of side effects, leukopenia in combined group was less frequent than that in control group (p<0.05). More patients in the control group were found to suffer liver toxicity. Conclusions: Javanica oil emulsion injection combined with chemotherapy could be considered as a safe and effective regimen in treating patients with advanced lung adenocarcinoma. It can improve the quality of life and reduce the possibility of leukopenia. Further clinical trials with a large sample size should be conducted to confirm whether addition of Yadanzi$^{(R)}$ to chemotherapy could increase the response rate, reduce toxicity, enhance tolerability and improve quality of life for patients with advanced lung cancer.

This study was performed from March to June 1994 in ANsung Medical Center. We investigated serum components of 78 diabetics in the center, in addition to the nutrient intake status and anthrophometric status of 60 diabetics among them. We separated the latter into 2 groups(ⅰ) less tan 5 years of diabetic duration and ⅱ) more than 6 years of diabetic duration) and analyzed the clinical characteristics of each group. The results are as follows : \circled1 The average ages of male and female subjects were 57.1 and 58.9 years, respectively. The average diabetic duration of male subjects was 4.8 years and that of female subjects was 5.9 . The major occupational field of both male and female subjects was agriculture(33.3%, 36.1%). 50% of male and 75% of female subject's monthly incomes were less than 600, 000 won and 75% of male and 94.4% of female subjects had weekly food expense less than 40, 000 won. The nutrient intake status of the subjects was lower than RDA on the whole. There was no big differences between 2 the male groups of different diabetic duration , but calorie, protein , fat carbohydrate, phosphorus, iron and Vit B$_1$intakes of the above 6 year female group were appearently higher than those of the under 5 year female group (p<0.05). There were different intake tendencies between male and female subjects . For females. the longer the diabetic duration, the less intakes of calorie, protein , fat carbohydrate, phosphorus, iron Vit B$_1$, Vit B$_2$, and niacin were observed. Furthermore, the longer the diabetic duration in females , the more intakes of energy and nutrients, except Vit C were observed. Fasting blood glucose levels were 155mg/dl and 164mg/dl and Postprandial glucose levels were 242mg/dl and 247mg/dl for males and females respectively. Hb of both males and females , and Ht of males met the lower limit of normal status, The serum TG level was higher than normal , so that they seemed to suffer from hyperlipidemia ; their high HbAIC status indicated that the management of diabetes mellitus was poor. The total protein level of female subject was higher when compared with that of males(p<0.05). All subjects blood pressure were higher than normal , and the longer the diabetic duration, the higher was the blood pressure. The serum HDL-cholesterol levels of the above 6 year group male subjects were lower(p<0.05) than those of the under 5 year male group subjects, and the former group's systolic and diastolic blood pressures were higher than those of the latter(p<0.05). Levels of serum total protein, albumin and TG of the above 6 year female group were lower than those of the under 5 year female group(p<0.05). As the diabetic duration was extended, HDL-cholesterol and LDL-cholesterol levels showed a tendency to increase, while Hb, Ht, total protein, albumin, and A/G, which represent the nutrients state of iron and protein, were inclined to decrease. This result showed that serum lipid components went bad. To summarize the results, the longer the diabetic duration, the worse were the male subjects nutrient intake status, but those of the female subjects were good. With respect to serum components and serum lipid subjects Fe, protein, nutrition status and serum lipid component got worse as the diabetic duration was extended , implying the possibility of diabetes mellitus complication grows.

배경: 다한증환자에서 교감신경 절단술은 효과적인 치료방법으로 수술직후에는 만족도가 높으나 시간이 경과함에 따라 만족도가 떨어지는데, 그 원인은 보상성 다한증이 주원인이라 할 수 있다. 보상성 다한증은 일상생활에 아주 불편한 질환으로 그나 유발인자에 대해 많은 연구와 노력이 있었으나, 그에 대해 알려진 바는 없는 실정이다. 대상 및 방법: 계명대학교 의과대학 흉부외과에서 1999년 5월부터 2001년 6월까지 141례의 교감신경 절단술을 시행하였으며, 25례의 안면부 다한증은 두 번째 늑골에서, 116례의 수장부 다한증은 세 번째 늑골에서 교감신경을 절단하였다. 모든 례에서 추적이 가능하였고 보상성다한증의 유무에 따라 두군으로 나눈 후 성별, 나이, 체표면적, 교감신경 절단의 위치, 직업의 유무에 따른 보상성 다한증의 경향을 조사하였다. 결과: 전체 141례 중 보상성 다한증은 91례로 64.5%를 보였다. 보상성 다한증이 있는 군과 없는 군에서 체표면적, 교감신경 절단의 위치, 직업의 유무에 따른 차이는 없었으며, 평균연령은 보상성 다한증이 있는 군은 26.4세, 없는 군은 23.2세로 나타났다(p=0.09). 남녀 비에서 보상성 다한증이 있는 군은 남자 46명, 여자 45명(50.5%, 49.5%)이었으며, 없는 군에서는 남자 19명, 여자 31명(38.0%, 62.0%, p=0.16)으로 나타났다. 결론: 여러 결과에서 통계적으로 유의한 인자는 없었으나, 남녀 비와 평균연령에 있어서는 보상성 다한증의 경향에 근접한다고 볼 수 있었다. 향후 좀 더 많은 환자분석과 가족력, 그리고 정신적인 병력유무 등의 여러 인자들을 고려한다면, 보상성 다한증 발생의 예측인자조사에 도움이 되리라 생각된다.

One of the most important factors in sailing yacht design is an accurate velocity prediction. Velocity prediction programs (VPPs) are widely used to predict velocity of sailing yachts. VPPs, which are primarily based on experimental data and experience of long years, suffer limitations applied in realistic conditions. Thus, in the present study, a high fidelity velocity prediction method using the computational fluid dynamics (CFD) is proposed. Using the developed method, velocity and motion of a 30 feet sloop yacht, which was developed by Korea Research Institute of Ship and Ocean (KRISO) and termed KORDY30, were predicted in upwind sailing condition.

This study was conducted to investigate serum lipids and antioxidant vitamins status of male patients with cerebrovascular disease. The study consisted of 16 hospital patients(57.8$\pm$13.7 years) at 3 General Hospitals in Taegu who suffer from cerebrovascular disease and 21 healthy adults(55.5$\pm$7.2 years). The results were as follows: The systolic blood pressure of the patients(150.0$\pm$13.7mmHg) was sig nificantly higher than healthy control(126.0$\pm$17.4mmHg). In patients the percentages of drinking alcohol(more than 5 times/week) and smoking were also higher. And the patients had more stress than control. Total calorie, protein, carbohydrate, vitamin B1 and niacin intakes were significantly lower in the patients. The energy nutrients consumption reached the recommended level in all subjects who were investigated. HDL cholesterol(24.99 vs 37.86mg/dl) and vitamin E(12.94 vs 20.88mg/L) level showed significantly lower, but triglyceride level(175.50 vs 117.69mg/dl), total cholesterol/HDL cho lesterol(6.22 vs 4.39) and atherogenic index(5.22 vs 3.39) were significantly higher in the patient group. Therefore, it might be expected that refraining from drinking alcohol and smoking, and that having proper exercise and certain other healthy living habits which can decrease stress in addition suitable consumption of antioxidant vitamins can prevent the occurrence of cerebrovascular disease.

Mathematics and science are very closely related. Among the science areas, physic is strongly linked with mathematics. As the related mathematics skills were alloted later than the science contents in the national curriculum, students often suffer from science classes. Accordingly, an opinion have been claimed to teach the related mathematics skills prior to the science classes. However, it would be hard to arrange all science and mathematics contents in order. Instead of that, in this research, we taught students mathematics contents that are crucial for learning speed through science classes. We called that teaching strategy an integrated science and mathematics class. Then, we examined students' achievement in science as well as skills of mathematics to know the effectiveness of the strategy. We found that the average mathematics score of the whole class went up meaningfully. We also found that their science achievement was above than basic level. Moreover, the homeroom teacher of the students observed 3 aspects which showed the students were better than previous students. Finally, we divided the students into 4 groups by their science and mathematics achievement score and interviewed each group. As a result, we knew that interesting and confidence in science and mathematics quite exerted influence on their achievement.
