  • Cycling that transform human energy into mechanical energy is one of the man-machine systems out of sports fields. Benchmarking means "improving ourselves by learning from others', therefore benchmarking toward dominant cyclist is necessary on field. The goals of this study were to provide important factors on multi-disciplines (kinematics, physiology, power, psychology) for a tailored-training program that is suitable to individual characteristics. Two cyclists participated in this study and gave consent to the experimental procedure. One was dominant cyclist (years: 21 yrs, height: 177 cm, mass: 70 kg), and the other was non-dominant cyclist (years: 21, height: 176, mass: 70). Kinematic data were recorded using six infrared cameras (240Hz) and QTM (software). Physiological data (VO2max, AT) were acquired according to graded exercising test with cycle ergometer and power with Wingate test used by Bar-Or et. al (1977) and to evaluate muscle function with Cybex. Psychological data were collected with competitive state anxiety inventory (CSAI-2) that was devised by Martens et. al (1990) and athletes' self-management questionnaire (ASMQ) of Huh (2003). It appears that the dominant's CV of ankle joint angle was higher than non-dominant's CV and dominant's pedaling pattern was consistent in biomechanics domain, which the dominant's values for all factors ware higher than non-dominant's values in physical, and physiological domain, and their values between cognitive anxiety and somatic anxiety were contrary to each other in psychology. Further research on multi-disciplines may lead to the development of tailored-optimal training programs applicable with key factors to enhance athletic performance by means of research including athlete, coach and parents.

  • The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings deal with their materials and external appearance as an important factor, making up the urban image. But it was nearby impossible to evaluate the value of visual landscape with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. Such kinds of estimation can in some cases include arbitrary interpretations. In relation to this kind of problems, it is tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watch the urban landscape scenery constructed in a visual reality. The tested persons were 20 adult male and female with no color blindness and intact cognitive function. Light source with color filter was used for color environment in a dark soundproof chamber. The signal of EEG is analysed digitally and grouped into the ${\alpha}$ and ${\beta}$ waves. The result showed that relative power of ${\alpha}$ wave ratio increased in the natural landscape scenery with blue and green color. From these results it was possible to evaluate the human response, which is affected by urban and natural color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

  • Purpose: Adolescence is viewed as a critical period in the formation of health behavior and many health behaviors developed during this era persist into adulthood. Social-cognitive theory, self-efficacy as a central construct, has been used to predict and intervene the health behavioral patterns in adolescent. Previous research demonstrated that the attachment in childhood and self-esteem as psychosocial factors are predictors of the health efficacy in adolescent and it is viewed as solely an antecedent for the lifelong health behavior. Method: To investigate the path pattern of attachment in childhood, self-esteem and health efficacy in adolescents, 381 adolescents in high school from two urban cities in Korea were recruited for cross-sectional sample. Attachment in childhood was measured using Mother-Father-Peer Scale. Self esteem was measured with Hare self esteem. Perceived self efficacy in Health was measured by the School Health Efficacy Questionnaire. The path analysis revealed a significant relationship between attachment in childhood and self-esteem, self-esteem and health efficacy in adolescents. Self esteem was the strongest contributing factor for health efficacy in adolescent. The results suggest that attachment in childhood may aid in formulating positive self -esteem in adolescents and self-esteem played a major role in predicting health efficacy in adolescents. Conclusion: Therefore, self-esteem enrichment should be incorporated with adolescent health promotion and certainly should be a component in any health education program in school health program and interventions. These results have implications of psychosocial and family related factors on health promotion and health education for the health care provider with regard to primary and secondary prevention in adolescent population.

  • This study started with concerns for corporate philanthropy that is emerging as an alternative for resource development of social work field in Korea. However, corporate philanthropy is not operating as an accomplished conception yet, but as a type of the practical discourse. Therefore corporate philanthropy is interpreted a multiplicity of meanings is used ambiguously in social work practice field. This is because theoretical reviews on the conceptual thinking of corporate philanthropy are scant and is in need of empirical inquires into conceptual perception of social workers who uses this concept as a stakeholder to corporate philanthropy. After analyzing the data using Q methodology, the result shows that social workers' major perception patterns on corporate philanthropy perspective consists of three patterns; Win-Win Partnership, Social-obligation, Strategic Materialism. These patterns are classified by the dimension of 'classical view', 'socio-economic view', 'modern view' and 'philanthrophic view'. This result will attribute to develop theories, social work practice program and social worker' training program related corporate philanthropy. And to give facilities for lucid communication among practice and theory in social work field as it materializes the explicit conception of corporate philanthropy that is understood ambiguously in Korea.

  • Objective:Event-related potentials(ERPs) are electrical changes recorded at the surface of the scalp in response to stimulus presentation, and their latency and amplitude change according to cognitive processes. Through past studies of the auditory ERP in schizophrenia, the P300 has been reported to be statistically smaller and delayed in schizophrenia than comparison groups. However, studies of the visual ERP have not been systematically examined. The present study was designed to investigate the visual P300 in patients with schizophrenia and normal controls and to compare the pattern of P300 between them. Methods:The subjects were composed of patients(N=22) with schizophrenia by DSM-IV and normal controls(N=22). The visual ERPs were measured by the visual continuous performance test. P300 amplitude and latency measured on 5 scalp electrodes(Fz, Cz, Pz, $T_7$, $T_8$) were compared between patients and controls. Results:The P300 latencies measured on Fz, Cz, Pz, and $T_7$ electrodes were significantly longer in patients than controls(p<0.05). The P300 amplitudes in patients were smaller than controls. However, the difference between them was not statistically significant. Conclusion:Analysis of the visual ERPs showed that the P300 latency is significantly delayed and the P300 amplitude is slightly smaller in patients than controls. These results are similar to established studies of the auditory P300 in schizophrenia.

  • Objectives This study investigated the patterns of psychotropic medications prescribed to patients admitted to an open psychiatric ward. Methods We reviewed 4282 medical records of patients who were discharged from an open psychiatric ward from May 2003 through April 2014. Data were collected on each patient's age, sex, length of hospital stay, number of past admissions, discharge diagnosis, and kinds and dosages of psychotropic medications at discharge. Results Among the 1384 male and 2898 female patients, 3.56 psychotropic medications were prescribed on average, with the number increasing across years, from 3.30 in 2003-2008 to 3.76 in 2009-2014. Prescription rates of antipsychotics, anxiolytics, and hypnotics significantly increased in patients with depressive disorders, bipolar disorders, anxiety disorders, delirium, dementia, and amnestic and other cognitive disorders. Only lithium prescription rates decreased significantly. Prescriptions for two or more anxiolytics and antipsychotics increased during the survey years, while antidepressant polypharmacy rates decreased. Conclusions Recently, there has been a significant increase in the number of psychotropic medications prescribed, including antipsychotics, anxiolytics, and hypnotics. Caution should be exercised when prescribing medications to avoid cost increases and the risk of side effects, with uncertain gains in the quality of care.

  • The current research examines whether pitch contour shapes in North Kyungsang pitch accent contrasts provide a phonetic dimension for phonological discreteness in a mimicry task. Two pitch accent continua resynthesized were created for HH vs. HL and HH vs. LH. To confirm a phonetic dimension for accounting for pitch accent categories in North Kyungsang Korean, the mimicries of speakers of two dialects (i.e., North Kyungsang & South Cholla) were compared. One of the findings showed that, for North Kyungsang speakers, the range of mean f0 peak times was a phonetic dimension undergoing a continuous shift within a stimulus continuum for both HH vs. HL and HH vs. LH. On the other hand, for South Cholla speakers, there were no apparent shifts around categorical boundaries for either HH vs. HL or HH vs. LH. Regarding individual mimicries on f0 peak timing, there are many variations. For HH vs. LH, three North Kyungsang speakers showed a discrete pattern reflecting a shift in phonological categories, but for HH vs. HL, there was no such distinction showing a categorical shift, though there were statistically significant differences for two speakers. Interestingly, one of the North Kyungsang speakers showed a continuous phonetic dimension for both HH vs. HL and HH vs. LH. Lastly, the f0 valley timing did not exhibit a discrete or gradient phonetic dimension for speakers of either dialect. On the basis of these results, what is interesting is that the tonal target such as high tone in North Kyungsang pitch accent categories within the autosegmental-metrical (AM) theory may be realized within individual cognitive systems for representing the interaction of perception and production.

  • Natural sleep pattern and its physiology in childhood are much different from those in adulthood. Several aspects of clinical evaluation for sleepiness in childhood are more difficult than in adulthood. These difficulties are due to several factors. First, excessive sleepiness in childhood do not always develop functional impairments. Second, objective test such as MSLT may not be reliable since it is hard to be certain that the child understand instructions. Third, sleepiness in children is often obscured by irritability. paradoxical hyperactivity, or behavioral disturbances. Anseguently, careful clinical evaluation is needed for the sleepy children. Usual causes of sleepiness in children are the disorders that induce insufficient sleep such as sleep apnea syndrome, schedule disorder, underlying medical and psychiatric disorder, and so forth. After excluding such factors, we can diagnose the hypersomnic disorders such as narcolepsy, Kleine-Levin syndrome, and idiopathic central nervous system hypersomnia. Among the variety of those causes of sleepiness, I reviewed the clinical difference of narcolepsy and obstructive sleep apnea syndrome in childhood compared with in adulthood. Recognition of the childhood narcolepsy is difficult because even severely sleepy children often do not develop pathognomic cataplexy and associated REM phenomena until much later. Since childhood narcolepsy give srise to many psychological, academical problem. Practicers should be concerned about these aspects. Childhood obstructive sleep apnea syndrome is different from adult obstructive sleep apnea syndrome too. Several aspects such as pathophysiology. clinical feature, diagnostic criteria, complication, management, and prognosis differ from those in the adult syndrome. An important feature of childhood obstructive sleep apnea syndrome is the variety of severe complications such as behavioral disorders, cognitive impairment, cardiovascular symptoms, developmental delay, and ever death. Fortunately, surgical interventions like adenotosillectomy or UPPP are more effective for Childhood OSA than adult form. CPAP is a "safe, effective, and well-tolerated" treatment modality too. So if early detection and proper management of childhood OSA were done, the severe complication would be prevented or ever cured.

  • Purpose: The purpose of this research was twofold: to compare the short-term efficacy of once-off education versus repetitive education (RE) of patients suffering from temporomandibular disorders (TMDs) and to determine whether there was any correlation amongst patient demographics, recommendation adherence degree and pain levels. Methods: A total of 848 patients with TMDs were enrolled. The control group consisted of patients who received a standard conservative treatment (STD) over at least 6 visits with education provided only during the first visit. The experimental group consisted of patients who received STD but had also been given RE (STD+RE). The RE was delivered through a standardized self-assessment questionnaire (SAQ) that was completed by the patient during each visit. Pain, which included maximum comfortable opening (MCO) of the mouth and limitation of mouth opening (LOM), was compared between the two groups. Behavior pattern and reported pain level changes in the group who used the SAQ were also analyzed. Results: The LOM was significantly improved in all of the experimental group patients (especially in females under 30 years of age, p<0.05). The MCO was significantly higher in females (p=0.029). All of the patients displayed improvements in their habits following RE, which resulted in a strong correlation with pain reduction. Adhering to the recommendations regarding questions 14 and 15 of the SAQ appeared to have the greatest effect on pain reduction. Conclusions: These results clearly demonstrate that RE is more effective than once-off education for TMD patients who are female or under 30 years of age.
