As employment changes quickly in structure, enterprises put more and more stress on basic vocational competency skills. This study aimed to grasp the basic vocational competency skills of S College Department of Radiological Technology students and present the basic data. The gathered data was analyzed using T-Test and Oneway ANOVA. The analysis showed that the students mostly had average or higher levels in the seven areas of basic vocational competency skills. Reading and writing skills among communication skills were the lowest, followed by the skills of understanding global culture and using foreign languages among organization understanding skills, and then by numeracy skills. On the contrary, interpersonal relationship skills were the highest in level. This indicates that the students will establish good interpersonal relationships with hospital patients and members. There were also statistically significant differences in reading and writing skills among communication skills, numeracy skills, and the skills of understanding global culture and using foreign languages among organization understanding skills. This study measured the basic vocational competency skills of S College Department of Radiological Technology students, which might somewhat restrict the application of its results to the students of all universities. The results show that students should be instructed to improve the skills of communication, numeracy, organization understanding, self-management skills, etc. Therefore, it seems necessary using various programs customized to school years and student levels and performing education properly connected to industrial establishments to foster the workforce with excellent basic vocational competency skills.

The aim of this study analyzed the important level (IL) and understanding level (UL) including the Borich's need for students preparing of the national examination for radiological technologists at online open chatting room. A total of 254 survey were collected from a total of 1,016 students who used open chatting room from December 13 to December 16, 2022. A general characteristics were the age, gender, curriculum (3 or 4 years), grade and area. The IL, UL, learning satisfaction (LS), learning achievement (LA) and intention to continue using (ICU) were analyzed by using the 5 point Likert scale. There was no significant difference the LS, LA, and ICU according to general characteristics (p>0.05). There was a statistically significant difference a total of sixteen subjects based on the t-test results of the response values from the IL and UL (p<0.05). The total of ten subjects with the highest priority in the Locus for Focus models were the Ultrasonography, Human anatomy, Magnetic resonance imaging, Radiation therapy, Cardiovascular and intervention, Computed tomography, Human physiology, Radiographic imaging, Fluroscopic radiography, and Nuclear medicine) that the Borich's need was also the same as the top 10 ranked subjects. The LS (4.23±0.72), LA (4.18±0.73), and ICU (4.15±0.78) for open chatting room were high. This study identified the subjects most needed by college students by the Borich's need analysis. First, it is necessary to provide intensive education on subjects with high scores that are most needed by college students. Second, it is necessary to improve the teaching method for subjects with low need and low level of understanding.

The Purpose of this study is to compare the bone marrow density measured by quantitative ultrasonometry (QUS) between men and women. Questionnaires for general characteristics were obtained from 104 participants, and then their both calcaneus was measured by using QUS. Sex differences for bone marrow density (BMD) were analyzed by an Independent t-test using the SPSS 19.0 program. Of 104 participants, women and men were 69(66.3%) and 35(33.7%), respectively. T-value of left calcaneus was high significantly in women than that in men(0.443 vs. 0.031, p=0.161) as well as that of right calcaneus(0.555 vs. 0.049, p=0.093). T-value of right calcaneus was high than that of left calcaneus in women and men (not significant, p>0.05). T-value of both calcaneus was increasing with physical activity. T-value of calcaneus was no statistically significant with age and body mass index. The BMD of women is high significantly more than that of men, and BMD is relation with physical activity.

The bone mineral density built in adolescence and college term is formed to the highest level between 25 years old and 35 years old and the formed bone mineral density is decreasing in the middle years and senescence. Decrease of the bone mineral density causes Osteopenia and an increase of dangerousness of a bone fracture which become social health problems. This research is to give guidance for the right living style by surveying the relation between the bone mineral density and college students' life. The result is like below. First of all, most objects of the research were insufficient of quantity of motion and the diet they have was consisted of instant food. It was far from the right living habit and exercise and the bone mineral density was also low. Second of all, male students showed more osteopenia than female students in this research and the smokers' bone mineral density was lower than nonsmokers, which proved that smoking in adolescence was related to the bone mineral density. Finally, the opportunistic eating and living style and the excessive diet and unequal caloric intake caused by the notion of preference for a slim person are considered to be the main reasons for the decrease of the bone mineral density.

The decrease of bone mineral density gives rise to the outbreak of osteopenia and makes the possibility of a bone fracture. It makes health problems in society. It's very important to prevent osteopenia in advance. Also it's critical to prevent and take care of it in adolescent because it's the most developing period comparing to middle ages because that bone mineral density decreases. There are genetic, physical and enviromental factors that affect bone mineral density. Recently, a lifestyle and eating habits are also changing as the society atmosphere is gradually doing. This study have shown that 134 women and 75 men was chosen and responded to the survey of measuring bone mineral density and investigating a lifestyle. The measure of bone mineral density is to use Dual energy X-ray absorptiometry(DEXA) and check femoral neck and lumbar spine. Also questionaries was required to pre-made survey about their lifestyles. Analysis of data was done with SPSS program. Multiple regression analysis was used for the relation of bone mineral density, the heigths and BMI. The sample of Groups are checked for drinking, smoking or excercising about differences by t-test. The results of the experiments were; first, there is statistically significant differences in the comparisons between BMD and BMD. But there isn't any special correlation between drinking, smoking and BMD. Secondly, bone mineral density becomes low related to an intake of caffeine. Particularly, this is statically significant on women. Also there is statically significant correlation between femoral neck and quantity of motion for both men and women. Third, there is significant relation between eating habits and bone mineral density on women's lumbar spine. However, there is no significant relation between men's lumbar spine and women's one. Therefore, to prevent osteopenia, it's good to abstain from intaking caffeine within an hour after a meal. In addition, it's helpful to walk or run regularly and have a balanced meal.

The purpose of this study was to measure maximum bite force and to investigate its relationship with anteroposterior, vertical, and transverse facial skeletal measurements. From among the dental students at the College of Dentistry, forty subjects (26 male and 14 female) were selected. With two sets of strain gauge, maximum bite force at the right and left first molars and anterior teeth was measured in the morning and afternoon. After taking lateral and posteroanterior cephalograms, fifty and nineteen variables were evaluated, respectively Paired t-tests and an independent t-test were done and correlation coefficients were obtained. 1. The maximum bite force at the first molars was $68.0\pm13.9kg$. in males and $55.6\pm10.5kg$ in females (p<0.05) while the force at the anterior teeth was $8.4\pm4.9kg\;and\;1.1\pm3.4kg$ respectively (p<0.05). 2. Some tendency for a greater value of maximum bite force at the preferred side was observed but not statistically significant (p>0.05). 3. Significant difference was observed between the strong bite force group and the weak bite force group in some cephalometric and other measurements (p<0.05). N-S-Ar, S-Ar-Go, FH-Hl, IMPA and MMO showed a significant difference in posterior maximum bite force (P). N-S-Ar and FH-H1 also showed a significant difference in anterior maximum bite force (A). 4. Several cephalometric variables showed some correlation with maximum bite force (p<0.05). N-S-Ar, S-Ar-Go, UGA, FH-H6, FH-H1, body weight and MMO were significantly correlated with posterior maximum bite force (P). Go-Me, P-1 and IMPA were significantly correlated with anterior maximum bite force (A).
