The purposes of this study were to compare pelvic tilt. range of motion(ROM) of hip rotation, and leg length difference before and after manipulation and to investigate correlation between changes of each variables after manipulation of sacroiliac pint in 31 low back pain patients(11 males, 20 females) with sacroiliac pint dysfunction. The sacroiliac pint of patients was manipulated on the side of anterior pelvic tilt, using the technique described by Stoddard(1962) and Greenmann (1996). I used this technique because it usually eliminated sacroiliac Pint dysfunction in one treatment session. SPSS for window computer system was used to analyze the data. Also t-test was performed for comparison of the variables before and after manipulation, and Pearson product-moment correlation analysis and regression analysis were performed for changes of each variables after manipulation. The result were as follows: 1. The pelvic tilt after manipulation was significantly decreased(mean=$2.79^{\circ}$) compared with the pelvic tilt before manipulation(p=.001). 2. The PROM of hip internal rotation ipsilateral to anterior pelvic tilt after manipulation significantly decreased (mean = $1.88^{\circ}$) compared with hip internal rotation before manipulation (p=.008). The PROM of hip internal rotation ipsilateral to posterior pelvic tilt after manipulation significantly increased(mean = $1.29^{\circ}$) compared with hip internal rotation before manipulation (p=.029). 3. The PROM of hip external rotation ipsilateral to anterior pelvic tilt after manipulation significantly increased(mean=$2.42^{\circ}$) compared with the hip external rotation before manipulation(p=$2.42^{\circ}$) compared with the hip external rotation ipsilateral to posterior pelvic tilt after manipulation significantly decreased(mean = $1.84^{\circ}$) compared with the hip external rotation before manipulation (p=.008). 4. Leg length difference after manipulation significantly decreased(mean=2.15 mm) compared with leg length difference before manipulation (p=.008). Regression analysis revealed that a fair correlation was found between change in leg length difference and change in anterior pelvic tilt after manipulation(p=.009). 5. Pearson product-moment correlation coefficient was used to assess differences of the variables after manipulation. A fair correlation was found between change in leg length difference and change in anterior pelvic tilt after manipulation(r=.462, p<.01). A fair correlation was found between change in anterior pelvic tilt and change in hip internal rotation ipsilateral to anterior pelvic tilt(r=.397, p<.05) and between change in anterior pelvic tilt and change in hip external rotation ipsilateral to anterior pelvic tilt(r=.516, p<.01). A fair correlation was found between change in posterior pelvic tilt and changes in hip internal rotation ipsilateral to posterior pelvic tilt (r=.441, p<.05) and between change in posterior pelvic tilt and change in hip external rotation ipsilateral to posterior pelvic tilt(r=.361, p<.05). A fair correlation was found between change in hip internal rotation ipsilateral to anterior pelvic tilt and change in hip external rotation ipsilateral to posterior pelvic tilt(r=.388, p<.05) and between change in hip internal rotation ipsilateral to posterior pelvic tilt and change in hip internal rotation ipsilateral to anterior pelvic tilt(r=.426. p<.05).

Background: The objective of this study is to determine knowledge about lung cancer among secondary school male teachers in Kudat, Sabah, Malaysia. Materials and Methods: A cross-sectional study was conducted among three secondary schools located in Kudat district, Sabah, Malaysia during the period from June until September 2012. The protocol of this study was approved by ethics committee of Management and Science University, Malaysia. The aims were explained and a consent form was signed by each participant. Respondents were chosen randomly from each school with the help of the headmasters. Self-administrated questionnaires, covering socio-demographic characteristics and general knowledge of lung cancer, were distributed. Once all 150 respondents completed the questionnaire, they passed it to their head master for collecting and recording. All the data were analyzed using Statistical Package for the Social Sciences (SPSS) version 13. ANOVA and t-test were applied for univariate analysis; and multiple linear regression for multivariate analysis. Results: A total of 150 male secondary school teachers participated in this study. Their mean age was $35.6{\pm}6.5$ (SD); maximum 50 and minimum 23 years old. More than half of the participants were Malay and married (52%, 79%; respectively). Regarding the knowledge about lung cancer, 57.3% of the participants mentioned that only males are affected by lung cancer. Some 70.7% mentioned that lung cancer can be transmitted from one person to another. More than half (56.7%) reported that lung cancer is not the leading cause of death in Malaysian males. As for risk factors, the majority reported that family history of lung cancer is not involved. However, 91.3% were aware that cigarettes are the main risk factor of lung cancer and more than half (52%) believed that second-hand smoking is one of the risk factor of lung cancer. More than half (51.3%) were not aware that asbestos, ionizing radiation and other cancer causing substances are risk factors for lung cancer. Quitting smoking, avoiding second-hand smoking and avoiding unnecessary x-ray image of the chest (53.3%, 96.0%, 87.3%; respectively) are the main preventive measures mentioned by the participants. For the factors that influence the participants knowledge, univariate and multivariate analysis showed that only race was significant. Conclusions: Overall, the knowledge of school male teachers about lung cancer was low. However, few items were scored high: cigarettes are the main risk factor; avoiding second-hand smoking; and avoiding x-rays. Interventions to increase lung cancer awareness are needed to improve early detection behavior. Increase the price of pack of cigarettes to RM 20 and banning smoking in public places such as restaurants are highly recommended as primary preventive measures.

The introduction of a team system to any organization is usually to improve that organizations dynamics, by increasing the proper adaptation to rapidly changing environments, by reducing approval procedures, and by promoting power authorization. In this regard, this study was carried out in an attempt to determine (1) whether or not the introduction of a team system can be as effective in hospital organizations as it has been in business organizations, and (2) what behavior factors influence such effectiveness. For the current study, questionnaires were distributed to the employees of a university hospital in Pusan. Four hundred eighty three of them(94.7%) were retrieved and analyzed through statistical processes. The three types of variables that were found to influence team effectiveness were: (1) independent variables of team organization characteristics, such as communication, organizational atmosphere, leadership and team knowledge, (2) intervening variables of team organization characteristics. such as job autonomy, technological variety, task subjectivity, task feedback and task importance, and(3) the dependent variables of team level effectiveness, such as job satisfaction and commitment to team organization. The gathered data were processed by using the 6.12 version of the statistical program SAS(Statistical Analysis System), and the reliance coefficient of those measured variables was then evaluated as an average of 0.78. The influence of team level effectiveness was analyzed by using multiple regression analysis. These differences in effectiveness were then analyzed on the basis of related mean values, while the differences among demo-sociological characteristics were analyzed by using the dispersion analysis(ANOVA) and the t-test. The results of the study can be summarized by the following. First, regarding the relationship between team organization characteristics and team level effectiveness, all of the factors including communication, organizational atmosphere, leadership and team knowledge were found to have a significant influence on effectiveness. Second, the factors of team job characteristics, such as technological variety, task importance and job autonomy, had significant effects on job satisfaction and organizational commitment among the teams members. Team level effectiveness was generally high, while team job satisfaction was higher the teams organizational commitment. Third, regarding the demo-sociological characteristics, team level effectiveness was found to be higher among those who were older, who had more job experience, and who had a higher position. Comparing the differences among job types, the effectiveness was relatively higher in the fields of nursing and administration/management then in other fields. Further study should be done towards the setting of variables for characteristics of hospital organization, developing suitable methods of measurement, and researching individual level effectiveness.

The Natural Science High School is specialized in vocational education or training related to natural sciences such as biology or chemistry. Therefore, natural science high school students are expected to possess a high level of science learning motivation. This study aims to explore natural science high school students' level and structure of science learning motivation by comparing students in general high school. One hundred ninety three students from a natural science high school and 208 from a general high school participated in this study. We administered a questionnaire that consisted of seven science motivation components: 1) career motivation; 2) science grade motivation; 3) understanding the relevance of scientific knowledge; 4) need for learning science; 5) self-determination; 6) self-efficacy; and 7) attitudes toward science class. We employed independent t-test, path analysis, bivariate correlation, and stepwise multiple-regression for the statistical analyses. Our findings illustrated that the natural science high school students' levels on all seven variables were significantly lower than the general high school students.' The path analysis illustrated that career motivation and science grade motivation had relatively stronger influence on self-determination and self-efficacy in the natural science high school student sample than in the general high student sample. The explanatory powers of four independent variables (career motivation, science grade motivation, understanding the relevance of scientific knowledge, and need for learning science) predicting self-determination and self-efficacy were 30% higher in the natural science high school student sample than in the general science high student sample. These results suggested that natural science high school students' science learning motivation may be easier to change by extrinsic motivations such as career and science grade motivation.

The increased demand and consumption of coal has intensified problems associated with disposal of solid waste generated in utilization of coal. Major utilization of coal by-products has been in construction-related applications. Since fly ash accounts for the part of the production of utility waste, the majority of scientific investigations have focused on its utilization in a multitude of use, while little attention has been directed to the use of bottom ash. As a consequence of this neglect, a large amount of bottom ash has been stockpiled. However, the need to obtain safe and economical solution for its proper utilization has been more urgent. The study presented herein is designed to ascertain the performance characteristics of bottom ash, as autoclaved lightweight foamed concrete product. The laboratory test results indicated that tobermorite was generated when bottom ash was used as materials for hydro-thermal reaction. According to the analysis of variance, at the fresh state, water ratio affects on flow and slurry density of autoclaved lightweight foamed concrete, but foam ratio influences on slurry density, while, at the hardened state, foam ratio affects on the density of dry and the compressive strength but doesn't affect on flexural and tensile strength. In the results of response surface analysis, to obtain target performance, the most suitable mix condition for lightweight foamed concrete using bottom ash was water ratio of 70$\sim$80% and foaming ratio of 90$\sim$100%.

The purposes of this study were to investigate the eating status and to analyze expenditures of the traditional fermented foods. A structured questionnaire survey was conducted from 370 housewives in Jeonbuk province and there were 300 usable samples(81.1%) valid for analysis. For the statistical analysis, the data was analyzed by $x^2$-test using SPSSIPC 12.0 for windows. The results of this study were as follows : 1. In the investigation on the eating status of the traditional fermented foods, Kimchi showed highest intake frequency(over once a day) and next Doenjang, Gochujang, Ganjang were consumed $2\;{\sim}\;3$ times per week. Jeotgal and Jangajji consumption showed the significant difference frequencies between the age groups(p < 0.001). The frequencies of using the home-made fermented foods were either similar or decreased, while the manufactured products were either similar or increased. The reasons behind the decreasing consumption were 'because of appetite change(47.0%)', 'the effect of western food(25.2%)' and 'dislike of salty food(17.4%)'. 90.7%(Kimchi), 54.9%(Doenjang), 54.8%(Gochujang), 53.2%(Cheongkukjang) of respondents knew the methods of preparation, while 62.5%(Ganjang), 41.1%(Jeotgal,) 31.2%(Jangajji) of respondents didn't know the methods of preparation. 2. In the analysis of the expenditure for the purchasing of the traditional fermented foods, most of the respondents procured Kimchi, Doenjang, Gochujang from their families or relatives, but they bought Ganjang, Jeotgal, Jangajji in the markets. And most of the respondents bought the fermented foods in the general merchandise stores or the department store except Kimchi. The places of buying Kimchi were specialty stores(34.6%), general merchandise stores or department stores(25.0%). Overall scores of satisfaction for the quality of manufactured fermented foods showed 3.29 of 5 - point scales. The average cost per month of Kimchi was 19,550won and Gochujang 7,878won, Doenjang 5,764won, Jeotgal 5,439won, Jangajji 5,412won, Ganjang(for soup) 4,714won, Cheongkukjang 4,677won, Ganjang(for seasoning) 4,464won, and total cost was 20,920won. The reasons behind purchasing the traditional fermented foods were 'because of convenience(58.4%)', 'no time to make by oneself(23.0%)' and 'for not knowing the making methods(12.8%)'. The problems of the manufactured traditional fermented foods were 'worry about safety of the raw materials or additives(71.2%)', 'lack of sanitation(12.0%)'. The most important thing considered in purchasing was 'materials and origins(86.6%)' and next 'quality(64.1%)' was another important thing.

The purpose of this research is to study the cause of obstruction in various knit pattern structures by understanding the needs of the customers, and to develop knitted fabric goods that satisfy the individual taste of consumers and that reflecting the latest fashions. Actual conditions of the manufacturer's designing processes must be examined. In addition, a comparison analysis of fashion sensibilities and preferences between producers and consumers had been made in order to study developing knit pattern structures. Questionnaires and interviews had been used as research methods. The research involved two groups: one group consisted of 57 producers, which included designers, programmers, and merchandisers working for a knit manufacturer in Seoul, while the other group consisted of 74 consumers, which included students with knitted fabric design as their major and those who have working knowledge of knitted fabrics. For a more accurate evaluation, 28 out of 150 patterns have been selected through a preliminary study conducted by 24 designers. On the 28 knit patterns, a sensibility evaluation had been made through the use of the sense of sight and sense of touch, which was followed by a frequency analysis, cluster analysis, and t-test using SPSS 12.0. The results are as follows: the fashion sensibility evaluation on knit patterns showed that structures, such as racking II or lace II, are typically elegant ('elegance'), while structures, such as links I or racking I, are typically 'active.' Furthermore, a 'country' image was displayed in structures such as cable I, cable II, and miss II. Links I appeared as 'sophisticated'. Miss I and milano were said to have 'modem' images. Lace II was regarded as 'ethnic', while racking II was said to have a 'romantic' image. 2:1 rib and milano were generally thought to be manly ('manish'). The fashion sensibility scale for each knit pattern has been made based on the above results. Based on producer and consumer responses, the sensibility evaluation on knit pattern structures showed that the two groups had similar preferences in knit pattern structures. Therefore, the fashion sensibility scale developed in this study can be used as a basic data for structure development when designing knitted fabric goods.

Introduction: This study evaluate the soft tissue changes to the upper lip and nose after Le Fort I maxillary posterosuperior rotational movement. Materials and Methods: Twenty Skeletal class III patients, who had undergone bimaxillary surgery with a maxillary Le Fort I osteotomy and bilateral sagittal split ramus osteotomy, were included in the study. The surgical plan for maxilla was posterosuperior rotational movement, with the rotation center in the anterior nasal spine (ANS) of maxilla. Soft and hard tissue changes were measured by evaluating the lateral cephalograms obtained prior to surgery and at least 6 months after surgery. For cephalometric analysis, four hard tissue landmarks ANS, posterior nasal spine [PNS], A point, U1 tip), and five soft tissue landmarks (pronasale [Pn], subnasale [Sn], A' Point, upper lip [UL], stomion superius [StmS]) were marked. A paired t test, Pearson's correlation analysis and linear regression analysis were used to evaluate the soft and hard tissue changes and assess the correlation. A P value <0.05 was considered significant. Results: The U1 tip moved $2.52{\pm}1.54$ mm posteriorly in the horizontal plane (P<0.05). Among the soft tissue landmarks, Pn moved $0.97{\pm}1.1$ mm downward (P<0.05), UL moved $1.98{\pm}1.58$ mm posteriorly (P<0.05) and $1.18{\pm}1.85$ mm inferiorly (P<0.05), and StmS moved $1.68{\pm}1.48$ mm posteriorly (P<0.05) and $1.06{\pm}1.29$ mm inferiorly (P<0.05). The ratios of horizontal soft tissue movement to the hard tissue were 1:0.47 for the A point and A' point, and 1:0.74 for the U1 tip and UL. Vertically, the movement ratio between the A point and A' point was 1:0.38, between U1 tip and UL was 1:0.83, and between U1 tip and StmS was 1:0.79. Conclusion: Posterosuperior rotational movement of the maxilla in Le Fort I osteotomy results in posterior and inferior movement of UL. In addition, nasolabial angle was increased. Nasal tip and base of the nose showed a tendency to move downward and showed significant horizontal movement. The soft tissue changes in the upper lip and nasal area are believed to be induced by posterior movement at the UL area.
