The purpose of this study is to analyze the penalty types and characteristics of world judo players. Using a total of 19,889 penalties in 9,737 matches at the World Judo Grand Prix, the team draws a difference in the types and time of fouls according to gender, weight class and time. Results Both foul play and warning showed gender differences, and both men and women affected warning rates in weight class and time classification. In addition, fouls caused by non-combat behavior and camouflage attacks have a forward direction of time, and a low time of fouling by heavyweight athletes. Judo athletes and leaders expect to be used as basic data based on scientific data, such as training, skills, tactics and motivation, taking into account the characteristics of the foul type. Requires follow-up studies of scoring relationships and winning factors.

This study is to analyze the physical environment and conduct spatial data for bicycle road system in changwon. Index for evaluation index was developed based on literatures. Then the level of importance and weight have been modified through experts review. Finally, index with eight categories such as greenness(40% over), bicycle road connectivity(1.8, 9.8%), road type bike(bicycle lane, 24.4%), pave type(asphalt 72.5%), illegal parking(none, 93.9%), bike road surface visibility(exist, 46.8%), vehicle speed limits(30km, under), vehicle traffic(500/hr under, 44.3%) have been applied to empirical investigation. Collected data has been hierarchically classification by ArcGIS Program. The Highest grades(score 31-35, level 1) occupied 35% of target destination. High level of greenness and load type has contributed to high score. In addition, average level of greenness of those destination was 35% and higher, which provide high degree of security and freshness for bicycle riding. Meanwhile, lowest level(level 5, which earned 15 point or less) occupied 24.5%. illegal parking, low level of greenness, and no surface sign caused low score.

The authors studied anxiety, using Zung's Self-Rating Anxiety Scale(SAS), in the subjects of 3,499 male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of SAS during the periods from January to February, 1986, and applied ANOVA and t-test on anxiety scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total anxiety scores between male and female students: male students scored $32.91{\pm}7.70$, female students scored $34.48{\pm}6.00$, (P<0.001). The anxiety scores relating to the items of sweating, apprehension, restlessness, and insommia were relatively higher in both groups. The anxiety scores relating to the items of faintness, mental disintegration, tremors, dizziness were lower in both groups. Thirty-nine male students(1.1%) showed seriously high anxiety scores of 50 or higher, while twenty-one female students(1.6%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but female showed more various symptoms and higher level of anxiety than males. Male students attending in pharmacy showed higher level of anxiety scores(P<0.01). There was a strong tendency toward higher anxiety scores in the students who were dissatisfied with their home atmosphere, colleges, department and familiarity of parents, and those who had pessimistic views of self image in the past, present, or future, in both groups(P<0.001).

To establish a suitability grouping system of paddy soils for multiple cropping of rice with other upland crops, the study was carried out after a few basic experiments. In succession to the results on basic experiment prior, the suitability system proposed and the results of application mentioned in this report were summarized as follows; 1. The factors of soil properties in the system were productivities represented by soil texture and drainage class, as well as salinity of surface and sub-soil pH of chemical properties were considered together with slope, warmth index, ground water table, parent materials etc. of soil physical or environmental conditions. The weights of the factors were combined with multiplicatively and additively so as the total marks of ideal soil to be 100. The system was composed with 5 suitability classes; over 91 mark is class I, under 60 mark class V, and each 10 point interval between classes. The limiting factors "P" (in the case that Physical properties or Productivity marks under 24), "S" (Surface slope less than 15) and "C" (Chemical condition below 15) etc. were appended up to two kinds to the classes except a part of soils in class I. 2. The areas where the warmth index exceed 110 in Yeongnam were 19% for class I, 22.7% for class II, 44.7% for class III, 11.5% for class IV, and 2.1% for class V. The rates in class I and II were slightly more than those of the whole country. 3. The points of each soil gained by the system had a positive correlation ($r=.922^{**}$) with the potential productivities.

There was a research to make it sure that among the contributing factors, the cognitive factor affects on TMD(temporomandibular disorders) or not, we used a questionnaire on new TMD patients who visited the Department of Oral Medicine at Pusan National University of Hospital(PNUH). Research was to identify the patients' understanding of the TMD. 120 patients who visited PNUH from 2007 June to August were tested and following are the results. 1. Those who were in Jr. college or had higher scholarship showed higher understanding than those with final graduation of high school or had lower scholarship(p=0.129). 2. Percentage of high scorers(score of $16{\sim}20$) were in Jr. college or had higher scholarship than those with final graduation of high school or had lower scholarship(p=0.098). 3. Both in those who scored higher than average and in those scored lower than average, there was no difference in the rate of previsit to local dental clinic, selection of special treatment(by professor), and attendance to next visit after their conservative treatment. 4. Patients who claimed that their symptom did not change after conservative treatment showed higher rate of pre-visit to local dentist(p=0.107) and selection of special treatment(by professor)(p=0.101) and many of them were in Jr. college or had higher scholarship(p=0.005). 5. The fact the patients who claimed their symptoms did not changed or got worsen had a tendency of higher scholarship showed that understanding of the TMD has little to do with the improvement of symptom and that TMD is a very complicated disease.

Field observations on the spatio-temporal distribution of organic matter of the surface sediment were carried out at 15 stations in the central parts of the South Sea of Korea from April 2002 to January 2003. The range of water temperature and salinity in bottom waters, mud content and water content of surface sediment were $8.06{\sim}23.35^{\circ}C,\;29.20{\sim}34.51\;psu,\;71.2{\sim}99.9%$ and $38.7{\sim}68.9%$, respectively. Measured parameters on the surface sediments of ignition loss (IL), chemical oxygen demand (CODs), phaeopigment, particulate organic carbon (POC) and particulate organic nitrogen (PON) also ranged in $3.9{\sim}l2.5%,\;9.60{\sim}44.05\;mgO_2/g-dry,\;1.58{\sim}29.51\;{\mu}g/g-dry,\;3.12{\sim}13.01\;mgC/g-dry$ and $0.49{\sim}2.00\;mgN/g-dry$, respectively. The spatio-temporal distribution of organic matter demonstrated higher concentrations offshore than at lesions near the coastal line. Higher concentrations occurred in the summer and spring. The results indicated that the origin of organic matter in surface sediments in the central part of the South Sea was autochthonous rather than allocthonous because the organic matter had an average C/N ratio of 6.44 (${\pm}0.51$). However, the composition of autochthonous organic matter was mainly derived from detritus rather than living phytoplankton, which was Indicated by the results of the POC/phaeopigment ratio. A principal component analysis (PCA) indicated that 73.2% of the variability in the data was described by two factors: 1) an 'environmental factor concerning the accumulation of materials (57.3%)' and 2) 'origin of organic matter and the composition by primary production (15.9%)'. The sedimentary environment in the central part of the South Sea was divided into four regions from the factor score of the PCA by the concentrations of organic matter and the composition ratio of organic matters from phytoplankton in surface sediments.
