The characteristics of carcass and meat yields of fattening pigs by production steps were investigated with Landrace (LL, n=41), Yorkshire (YY, n=33), and Duroc (DD, n=30), $F_1$ (LY, n=25), the Crossbred of LYD (n=48). Duroc had more weight loss in carcasses weight than that of the other breed(p<0.05). Yorkshire and $F_1$ had higher production weight in retail cut than that of the other pure or crossbred. Carcass from Landrace and $F_1$ were significantly longer in length than the other breed(p<0.05). $F_1$ produced wider carcass than the other breed. Carcass thickness at aitch bone was higher for $F_1$ and Crossbred than the other breed(p<0.05). Landrace, Yorkshire and $F_1$ produced more loin and tenderloin in weight than the other breed (p<0.05). Yorkshire and $F_1$ produced more picnic shoulder when compared to the other breed. The hind legs produced from Yorkshire and $F_1$ were higher in weight and the fore legs produced from the Crossbred were higher in weight. Duroc produced the lowest weight of belly among the breeds. The acceptance level of loin were extremely low for all breed. Landrace had the highest acceptance level for tenderloin. Yorkshire had the highest acceptance level for picnic shoulder and ham when evaluated by export standard of Japan. In conclusion, The introduction of pure breed and establishment of mating steps are necessary to produce highly accepted pork with high acceptance in carcass and meat yields.

As a number of new college students is dramatically decreasing, each college is trying to find various solutions for gathering many students and operating a school. In specialty, information such as entrance examination and matriculation status data is very important for a college to decide a direction of admission and public relations policy, and increase welfare of the school. Therefore, it is seriously needed for a school to introduce a matriculation management system that can do the effective analysis through various entrance examination and matriculation status data and decision factors of school. In this study, I developed a matriculation management system which can analyze information of applicants, successful candidates and registrants based on national framework data, and was able to analyze applicants, successful candidates, registrants by regional groups and the ratio of successful applicants against applicants and the change rate of applicants in the last 3 years. It is expected that the developed system can provide appropriate and rational information for public relations policy and operation to a college.

In line with the recent job insecurity, the preference for teaching jobs has been increasing for private and educational colleges. However, the T.O., announced by the Ministry of Education in tandem with the decreasing number of people, is decreasing every year, while the competition rate is rising steeply due to the increase in the number of students. As a result, the university is becoming a huge hagwon for teacher-nominee competitive tests as it tries to concentrate on the recruitment exam at the same time as entering the university. In this study, we will present a blueprint for school life to students enrolled in private universities by identifying the connection between the overall use of school life and study groups by students using deep learning.

The gated RapidArc may produce a dosimetric error due to the stop-and-go motion of heavy gantry which can misalign the gantry restart position and reduce the accuracy of important factors in RapidArc delivery such as MLC movement and gantry speed. In this study, the effect of stop-and-go motion in gated RapidArc was analyzed with varying gating window time, which determines the total number of stop-and-go motions. Total 10 RapidArc plans for treatment of liver cancer were prepared. The RPM gating system and the moving phantom were used to set up the accurate gating window time. Two different delivery quality assurance (DQA) plans were created for each RapidArc plan. One is the portal dosimetry plan and the other is MapCHECK2 plan. The respiratory cycle was set to 4 sec and DQA plans were delivered with three different gating conditions: no gating, 1-sec gating window, and 2-sec gating window. The error between calculated dose and measured dose was evaluated based on the pass rate calculated using the gamma evaluation method with 3%/3 mm criteria. The average pass rates in the portal dosimetry plans were $98.72{\pm}0.82%$, $94.91{\pm}1.64%$, and $98.23{\pm}0.97%$ for no gating, 1-sec gating, and 2-sec gating, respectively. The average pass rates in MapCHECK2 plans were $97.80{\pm}0.91%$, $95.38{\pm}1.31%$, and $97.50{\pm}0.96%$ for no gating, 1-sec gating, and 2-sec gating, respectively. We verified that the dosimetric accuracy of gated RapidArc increases as gating window time increases and efforts should be made to increase gating window time during the RapidArc treatment process.

In this paper we survey the career awareness, demand, and preparation of the students of the department of mathematics education and provide basic data for establishment of career diversification strategies. For this we examined the followings: (1) department selected time and motivation, (2) satisfaction with the selection and training courses, (3) hope and change for a career after graduation, (4) related jobs and career awareness. As a result, most of the students over the course of the high school and middle school chose a career in mathematics education, the biggest motivation appeared to be due to selection was deemed suitable for individual aptitudes. Due to this reason he/she is satisfied with the selection and training process and the curriculum of mathematics education appeared to think it would be helpful to his/her career. It can be observed that the number of students increased to think of another job, depending on the grade ascent. Mostly due to the difficulty of major study as grade up, high competition and low success rate of teacher employment test, employment reduction in the number of teachers.

This study conducted preliminary study to identify effective ways to use ChatGPT in traffic policing by analyzing ChatGPT's responses to the driver's license test and the road traffic accident appraiser test. I collected ChatGPT responses for the driver's license test item pool and the road traffic accident appraiser test using the OpenAI API with Python code for 30 iterative experiments, and analyzed the percentage of correct answers by test, year, section, and consistency. First, the average correct answer rate for the driver's license test and the for road traffic accident appraisers test was 44.60% and 35.45%, respectively, which was lower than the pass criteria, and the correct answer rate after 2022 was lower than the average correct answer rate. Second, the percentage of correct answers by section ranged from 29.69% to 56.80%, showing a significant difference. Third, it consistently produced the same response more than 95% of the time when the answer was correct. To effectively utilize ChatGPT, it is necessary to have user expertise, evaluation data and analysis methods, design a quality traffic law corpus and periodic learning.

The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.

The information of university entrance examination is important information to examinees as well as each universities. And this information can be used various fields. By using this information, examinees can choose the university which is most suitable regions through oneself's grade, and universities can decide the entrance policy and public relations of university. Furthermore, this information can be used important data to promote student's welfare. Therefore the introduction of College Matriculation System which can share between examinees and universities is keenly required. This study has developed the College Matriculation System which is Web2.0- based by using Naver Map API. By using this system, the information about candidates, and successful candidates and registrants for admission can be analysed, also the ratio of successful candidates in comparison with candidates and the change ratio of candidates during these three years can be analyzed. Besides, it can be supported the entrance public relations policy of universities by managing the public relations history, and it can be provided the information of university by grade to examinees on matriculation information based. Therefore, it was possible that manage and practical use of various data through connected with map based on web 2.0 which is opened. And it is considered possible to express more various information based on map constructing GIS system of user center that is not GIS system of existent offerer center.
