In this paper, we propose a method for estimating a walking direction by which a mobile robots follows a person using TRT (Tensor RT) pose, which is motion recognition based on deep learning. Mobile robots can measure individual movements by recognizing key points on the person's pelvis and determine the direction in which the person tries to move. Using these information and the distance between robot and human, the mobile robot can follow the person stably keeping a safe distance from people. The TRT Pose only extracts key point information to prevent privacy issues while a camera in the mobile robot records video. To validate the proposed technology, experiment is carried out successfully where human walks away or toward the mobile robot in zigzag form and the robot continuously follows human with prescribed distance.

Japanese Give and Receive Verbs are divided into "YARU", "MORAU" and "KURERU". These are influenced by the subject, speaker's viewpoint and meaning. Three verbs are used in a different way depending on who is the giver and who is the taker. I analyze "YARU" and "KURERU" Verbs used in TOUSEISYOUSEIKATAGI. It focus on politeness, gender, and meaning when combined with 'TE'. As an expression of politeness, 'Yaru' is to give to a person of lower social status or an animal or plant. 'Ageru' is to give to an equal ora person of lower social status nowadays. However, 'Ageru' which is treated as elegance of the language remained expression of respect, 'Yaru' is used when the receiver is a person of lower social status and equal social status in TOUSEISYOUSEIKATAGI. 'Kureru' is used when the receiver is a person of lower social status and equal social status, 'kudasaru' is used when a person of higher social status gives the speaker something in TOUSEISYOUSEIKATAGI. Women speakers use 'oyarinasai' 'oyariyo' 'ageru' 'okureru' and men speakers use 'yaru' 'kureru'. Speech patterns peculiar to men are 'kuretamae' 'kurenka'. If the verbs are joined to "TE", they obtain abstract meaning as well as a movement of things. They express some modality for action of the preceeding verbs. The modality has the following meanings ; good will, goodness, benefits, kindness, hopeness, expectation, disadvantage, injury, ill will and sarcasm.

In Korea, respect for the aged and filial devotion is treated as basic ethics for human life, and family takes care of the aged person mainly. Nowadays, family support on the aged person is prioritized than the others. However, number of aged person is growing, and family, which is used to protect the aged, becomes nuclear through industrialization. In addition, social advancement of female induces weakened supporting function of family, and all these issues generate the problem of protection for the aged as significant social problems. Author conducted oral inspection and questionnaire for the aged in some welfare facilities in Gyeongnam location from December 2005 to February 2006 to improve quality of life and oral hygiene of the aged. Through gathered data, the actual condition of oral hygiene management on the aged person in welfare facility was evaluated as fundamental data for project development on oral hygiene of aged person. Through the analysis of inspected data, the following conclusions are derived. 1. Management status of oral hygiene is mostly not good, and toothbrushing per day is 'one time' for the most cases. 2. In free-of-charge facility, monthly allowance is 'under 50 thousand won' for the most cases. 3. Time for visiting oral treatment facility is on 'when toothache is occurred' for the most cases. For treatment content, 'prosthetic dentistry' takes 36.8% in charged facility, and 'tooth extraction' is 27.0% for free-of-charge facility. 4. Average DMFT index of the aged in charged facility is 16.81, and free-of-charge facility is 21.71. 5.

The annual consumption of fishery products, particularly sea squirt (Halocynthia roretzi), per person has steadily increased in South Korea. However, the quantitative risk of Vibrio parahaemolyticus following intake of sea squirt has not been analyzed. This study focuses on quantitative predictions of the probability of consuming sea squirt and getting of V. parahaemolyticus foodborne illness. The prevalence of V. parahaemolyticus in sea squirt was evaluated, and the time spent by sea squirt in transportation vehicles, market displays, and home refrigerators, in addition to the temperature of each of these, were recorded. The data were fitted to the @RISK program to obtain a probability distribution. Predictive models were developed to determine the fate of V. parahaemolyticus under distribution conditions. A simulation model was prepared based on experimental data, and a dose-response model for V. parahaemolyticus was prepared using data from literature to estimate infection risk. V. parahaemolyticus contamination was detected in 6 of 35 (17.1%) sea squirt samples. The daily consumption quantity of sea squirt was 62.14 g per person, and the consumption frequency was 0.28%. The average probability of V. parahaemolyticus foodborne illness following sea squirt consumption per person per day was 4.03 × 10^-9. The objective of this study was to evaluate the risk of foodborne illness caused by Vibrio parahaemolyticus following sea squirt consumption in South Korea.

Background: The use of telemedicine for postoperative visits is increasing, especially in rural areas. Few studies have investigated its use for arthroscopic shoulder patients. This study aims to evaluate patient satisfaction with telemedicine for postoperative clinic visits following arthroscopic shoulder procedures in a rural setting. Methods: Patients were prospectively enrolled using the following exclusion criteria: <18 years, open procedures, and non-compliance follow-up at 6 weeks postoperatively. All patients completed a 13-question satisfaction survey, while telemedicine patients completed an additional, separate seven-question survey. Patients who switched groups completed a four-question prompt to determine the reasons for switching. Differences between groups were evaluated by either Student t-test or Mann-Whitney U-test. Results: The study enrolled 32 patients, with five patients following up by telemedicine and 27 in person. Age and distance from clinic were similar between patients who were assigned to the telemedicine group, completed the telemedicine visit, and opted for in-person visits (all p>0.05). Patient satisfaction did not vary significantly based on care by the surgeon, concerns being addressed, thoroughness of visit, overall clinical assessment at a prior visit, and improvements in pain and physical function (all p>0.05). Among patients who opted out of telemedicine visits, the most common reason was a preference to meet in-person but these patients agreed that telemedicine visits are a good idea. Conclusions: Regardless of type of follow-up, individuals reported similar levels of satisfaction with treatment during the visit and improvements in pain and physical function.

This article analyzes legal meaning and definition of medical practice examining Korean Supreme Court cases. Until now, there is no right answer about the meaning of medical practice and it is also hard to define of it. Moreover, not only Acts and regulations containing medical practice but also many cases ruling a person who practice medicine, the concept of medical practice involves various meanings. So, it has caused confusion. In order to solve this problem, this article divides the medical practice's meaning into range and nature within prohibition article of the Medical Act about unlicensed personnel who practice medicine. After providing a explanation of the meaning of medical practice according to amendment of the Act, this article disputes the meanings of the several cases following the amendment. And then analyzing non-medical person's unlicensed medical practice and medical person's unlicensed medical practice. In order to provide more accurate legal concept of medical practice when Korean government amends the Medical Act or making policies in this field, this classifying analysis approach should be needed. Looking at the result, in general, Korean Supreme Court has interpreted unlicensed prohibition clause of the Medical Act widely; not only non-medical person's unlicensed medical practice but also medical person's unlicensed medical practice. Therefore, this article suggests that the prohibition clause needs to be careful applying to non-medical practice. Because, in fact, even though there are some necessity of non-medical practice, there are no qualificatory or license system of non-medical practitioner in the Medical Acts or regulations forbidding whole non-medical practices. Furthermore, the Supreme Court has decided medical person's unlicensed medical practice too narrowly, thus it does not keep up with rapid change of medical development and people's demands these days. Regarding this subject, in order to take advantage of medical practitioners effectively and cope with increasing people's medical demands, this article proposes that medical person's unlicensed medical practice only to be prohibited in case of endangering our public health.
