유저의 일상 스케쥴을 제안하고 예측하는 서비스는 스마트 비서의 흥미로운 응용이다. 전통적인 방법에서는 유저의 행동을 예측하기 위하여, 유저가 직접 자신의 행동을 기록하거나, e-mail 혹은 SNS 등에서 명시적인 일정 정보를 추출하여 사용해왔다. 하지만, 유저가 모든 정보를 기록할 수 없기에, 스마트 비서가 얻을 수 있는 정보는 제한적이며, 유저는 유저의 일상의 routine한 정보를 기록하지 않는 경향이 있다. 본 논문에서는 스케줄러에 적히는 정형화된 일정인 스케줄과 비정형화된 일정을 만드는 일상 행동 패턴들을 동시에 고려하는 접근 방법을 제안한다. 이를 위하여 마코프 의사 결정 프로세스 (MDP)를 기반으로 하는 추론 방법과 역강화 학습 (IRL)을 통한 보상 함수 학습 방법을 제안한다. 실험 결과는 우리가 6주간 모은 실제 생활을 기록한 데이터 셋에서 우리의 방법이 기존 방법들보다 우수한 성능을 보임을 논증한다.

A 25-month-old boy was referred to the hospital due to large head detected on routine physical examination. At visit, dysmorphic facial appearances, including broad nose, prominent forehead, and coarse face, were noted. Nasal obstruction with nasal voice, prominent adenoids, and bilateral middle ear effusions were detected. His abdomen was distended, and liver and spleen were palpated about 3 finger and 2 finger breadths, respectively. He was operated for bilateral inguinal hernias. The motion of both elbow joints was mildly limited on supination and pronation. Urinary level of glycosaminoglycan was elevated and the enzyme activity of iduronate sulfatase in leukocytes was decreased. The mutational analysis of the gene iduronate 2-sulfatase (IDS) revealed c.263G>A (p.Arg88His) mutation. His developmental scale showed delayed development and there was cardiac valvular involvement (tricuspid regurgitation and mitral valve prolapse). After the diagnosis of Hunter syndrome, enzyme replacement therapy started on a weekly basis without progression of any clinical features. Here we report a case of early diagnosed Hunter syndrome detected by large head on routine examination. Thus, it is important to associate Hunter syndrome in the patient with large head especially, if there is the history of bilateral inguinal hernia and prominent adenoids to increase the possibility of early diagnosis and treatment.

Previous studies have investigated stepping over obstacles in treadmill walking training (TWT-OS) and treadmill walking training (TWT) alone for walking capacity not considering real physical activity. As such, we investigated the effects of TWT-OS on physical activity and changes in different levels of physical activity based on community ambulation in stroke patients. Thirty subjects were randomly assigned to either the experimental group or the control group, with 15 and 15 subjects, respectively. However, one subject from the control group was excluded because of inadequate treatment sessions. All subjects underwent routine physical therapy in the form of treadmill walking. The subjects in the experimental group underwent simultaneous training in obstacle-stepping while walking on the treadmill for 30 min/day, five times/week, for four weeks. Subjects were given a three-axis accelerometer to wear at the hip on a belt for one-week pre- and post-training physical activity. Step counts for seven days, average daily step counts, and the average of minutes spent in sedentary, light, and above moderate activity were chosen as outcome measures of physical activity. No significant differences between the groups were found in terms of step counts for seven days, average daily activity, or daily activity spent at sedentary levels after four-week interventions. However, the average daily activity spent at light levels (-42.60 min vs. -6.71 min) was significantly lower in the experimental group than in the controls. Conversely, average daily activity spent at above moderate levels was higher (19.86 min vs. 11.07 min) (p<.05) after adjusting for each baseline value. Significant pre- and post-training differences were found in all variables of the experimental group (p<.05). Thus, TWT-OS could improve physical levels above moderate activity as a community-oriented task more than simple repetitive waking on a treadmill, and it could provide an opportunity for patients ambulatory after stroke to participate in the community again.

This study tried to answer the question : 'How does the human communication happen at the oriental medicine hospital between nurse and patient?' To answer that, a micro-ethnographic research method was used. Researcher visited T university hospital of oriental medicine and observed nurse-patient communication from September 1997 to December 1997. The data was obtained through participant observation, interview, audio-tape recording, home video camera, field note-taking, and related documents. After reviewing the whole data and deliberate analysis, first, I learned that most oriental medicine nurses communicate with their patients for their routine nursing job like recording, hand-over to the next duty, report to doctor, etc. I named this type of communication as 'ritual communication'. Second, I can define major argument as follow : Human communication of oriental medicine between nurse and patient is performed more frequently and variously when nurse contacts the patient for the routine nursing activities than for the incidental activities. As a result of these understandings, I suggest that oriental nursing need to develop the body of knowledge and expand its role and independent nursing activity. Also the bureaucratic hospital management centered doctors must be changed reasonalbly.

This study is designed to positively transform a teacher's emotional state whilst teaching their classes and be able to create happier lessons for preschool children. To do this, a teacher needs to reflect upon current problems and take steps to deal with them. The data for this study was collected from participatory observation and in-depth interviews, making use of photos, a reflective teacher's journal and interview records from Mar. 28, 2011 through Oct. 7, 2011. The problems identified were, (1) teacher centered classes, (2) a daily routine filled with large group activities, (3) disruptive students, and (4) repetitiveness. The routes to greater classroom "happiness" are (1) rearranging seats, (2) "story sharing activities" in small groups, (3) making a separate "story sharing activity" area, (4) using small groups instead of large groups, (5) changing the daily routine. The role of the teacher in finding greater "happiness" are (1) meaningful, 'real observation', (2) discovering genuine change from small points, (3) power sharing, and (4) growing and developing with children.

As the society is superaging, the number of patients with movement disabilities due to musculoskeletal or nervous system illness is rapidly increasing. To improve public health and reduce medical expenses, it is essential to develop rehabilitation systems that allow patients to resume their daily-life activities. However, the existing musculoskeletal illness diagnosis and rehabilitation method is limited in terms of precision and efficiency because it is based on an empirical diagnosis and prescription without regard for individual characteristics. To overcome these limits, it is critical to design a novel concept of routine rehabilitation therapy device that is capable of inducing musculoskeletal balance by the precise analysis of musculoskeletal usage patterns via the motion and the muscle activity tracking of linked muscles. This study introduces the trend of on-skin sensor device technology for routine musculoskeletal monitoring and therapy. For on-skin rehabilitation systems, skin-adhesive and stretchable motion/posture, electromyography, pressure sensors, small-size and low-power wireless sensor interfaces, and user-friendly rehabilitation contents based on new algorithms are combined.

Alteration of the mGluR5 density is closely related to various brain diseases including schizophrenia, depression, Parkinson's disease, and Alzheimer's disease. Therefore, mGluR5 is considered as a valuable imaging biomarker for brain disease and many radiopharmaceuticals have been developed so far. Among them, [¹⁸F]FPEB has favorable pharmacokinetic characteristics, and this is the most frequently used radiopharmaceutical for preclinical and clinical studies. In the present study, we want to introduce the optimized radiosynthetic method for the routine production of [¹⁸F]FPEB using a GE TRACERlabTM FXFN pro module. In addition, the entire process was monitored with a webcam to solve the problems arising from the synthetic process. As a result, [¹⁸F]FPEB was prepared by nucleophilic substitution from its nitro- precursor at 120℃ for 20 min in dimethyl sulfoxide. Radiochemical yield was 13.7 ± 5.1% (decay-corrected, n = 91) with the molar activity of 84 ± 17 GBq/µmol at the end of synthesis. The radiochemical purity was determined to be above 96%. The manufactured [¹⁸F]FPEB injection for quality controls were carried out in accordance with an KIRAMS approved protocol, as per ICH and USP guidelines.

Purposes: The purposes of this descriptive correlational study were to assess knowledge and attitude toward smoking and smoking cessation counseling activity among nurses in a community, and to identify predictors of their smoking cessation counseling activity. Method: Nurses employed by institutions such as university hospital, hospital, clinic, and health department in a community were surveyed using a structured questionnaire. Of the nurses invited to participate in this study, 760 (88.5%) responded with completed questionnaires. Results: Nurses had relatively positive attitude toward their roles and responsibilities about smoking cessation counseling activity. However, smoking cessation counseling activity was not a routine part of their nursing practice. Moreover, the level of engagement with smoking cessation counseling activity was significantly different by working place. Nurses who were working at the university hospital, hospital, and health department were more actively engaged with smoking cessation counseling activity than nurses who were working at the clinic. Smoking cessation counseling activity was significantly correlated with knowledge of smoking. attitudes toward smoking-related issues, and self-efficacy for smoking cessation counseling activity. In the final stepwise multiple regression, smoking cessation activity was predicted by the nurses' working place, attitudes toward smoking-related issues, and self-efficacy for counseling knowledge and skills. Conclusion: In conclusion, nurses need to participate routinely and actively in smoking cessation counseling activity. To help nurses counsel and intervene patients regarding smoking cessation more effectively, it is essential to integrate educational information on smoking cessation intervention into curriculums of nursing schools as well as to offer smoking cessation intervention as a continuing education program available for currently practicing nurses.

Objective: To determine the energy consumed and muscle use during dance compared to different standard exercise devices. Design: Longitudinal study. Methods: Fifteen female subjects were evaluated to assess the energy cost and muscle activity during a 20 minute dance video compared to treadmill, elliptical track and bicycle ergometry. The later 3 forms of exercise were accomplished in four, 5 minute bouts at different intensities of exercise. Subjects were in the age range of 22-24 years old, were free of cardiovascular disease and did not have any neurological injuries. They were not sedentary and exercised at least twice a week. During the exercise, muscle activity was measured by the electromyogram recorded by surface electrodes on 6 muscle groups. A Cosmed metabolic cart was used to measure oxygen consumption during the exercise. Results: The aerobic dance video that was tested here was equivalent to a hard workout on any of the 3 exercise modalities. The dance routine was equivalent in terms of energy consumed to running at 225 watts of work or running for 20 minutes at a speed of 2 meters per second (4.47 miles per hour). Compared to the bicycle, it was equivalent to cycling at 112 watts for 20 minutes (2.25 kpm), and for the elliptical trainer, dance was equivalent to 435 watts. Concerning muscle use, the dance routine was the most balanced for upper, core and lower body muscles. Although the elliptical trainer was close, it required muscle less muscle use. Conclusion: A good dance video can be more effective than standard exercise equipment.
