Objectives : The Aim of this study was to investigate the clinical characteristics of male and female patients who have been suffered from headaches. The investigation was undertaken based on Qi-section(Methods of prescribing oriental herbal medicine) from DongEuiBoGam(東醫寶鑑). Methods: A statistical survey was conducted to compare the difference in clinical characteristics between male and female patients experiencing headaches. Oriental medical Diagnosis was used to classify all parients under the following categories Qi-deficiency (氣虛), Jing-dificiency (精虛), Food-stagnation (食積), Damp-accumulation (痰飮), Qi-stagnation (氣滯). Patients were treated using acupuncture therapy and herbal medicines. Results : 1. The ratio between male and female patients was about 1:3. 2. It showed that periods of illness were longer in female patients than in male patients. 3. The total number of treatments received was higher in female patients than in male patients. 4. Statistically, most female patients had Metopodynia and Migraines(Rt.), while male patients suffered mostly from Laryngalgia. 5. Male patients had feelings of strain in the head and female patients had splitting headaches. 6. Musculo-skeletal System and General Symptoms were frequently observed in male patients. Digestive System and Nervous System were frequently observed in female patients. 7. Results from oriental medical Diagnosis showed that male patients mostly had Qi-deficiency, ling-deficiency while the majority of female patients had Food-stagnation, Damp-accumulation, Qi-stagnation. 8. The recovery time for male patients was shorter than it was for female patients. The recurrence rate of the headaches were higher for female patients. Prognosis was better than in female patients in comparison to male patients. Conclusions : The statistical survey conducted was based on Qi-section of DongEuiBoGam. It had significant differences in clinical characteristics between male & femal patients.

Dust explosion hazards are always present when combustible dusts are manufactured or handled in the process. However, industries is experiencing difficulty in establishing chemical accident prevention measures because of insufficiency of information on dust explosion characteristics of combustible dust handled in industry. In this study, we investigated experimentally dust explosion characteristics of two kinds of multi-walled carbon nano tubes (MWCNT) different in particle size distribution and examined classification of dust explosion hazardous area for MWCNT manufacturing or handling process by applying the NFPA 499 code. As a result, $P_{max}$, $K_{st}$, LEL, MIE and MIT of MWCNT 1 having $124.2{\mu}m$ median diameter are obtained 6.3 bar, $56bar{\cdot}m/s$, $125g/m^3$, over 1000 mJ, and over $650^{\circ}C$. $P_{max}$, $K_{st}$, LEL, MIE and MIT of MWCNT 2 having $293.5{\mu}m$ median diameter are 6.2 bar, $42bar{\cdot}m/s$, $100g/m^3$, over 1000 mJ, and over $650^{\circ}C$, respectively. MWCNT 1, 2 are not categorized as combustible dust listed in the NFPA 499 Code for classification of dust explosion hazardous area because explosion severity and ignition sensitivity of MWCNT 1, 2 are below 0.35 and 0.01, respectively.

Today freeway is thought to be a very important transportation facility carrying tremendous traffic flow as the main corridor within the area of between the areas. However freeway is experiencing severe congestion and accidents by increased entrance ramp flow especially at peak time period. Ramp meters on the freeway entrance ramps that supply traffic to the freeway in a measured or appropriately regulated amount are needed for alleviating freeway congestion. Because ramp meters can be operated to discharge traffic at a measured or regulated rate thus maintaining more uniform speed on the mainline section maximizing the throughput to the freeway within the capacity of a downstream bottleneck and reducing the congestion related accidents. Thus the objectives in this study were to analyze the traffic characteristics on the freeway I-94 with ramp metering system before/after ITS technology in Detroit (Michigan) area compare shifts of the traffic characteristics on the freeway I-94 before/after ITS technology and finally suggest a better ramp metering strategy for the freeway system The following results were obtained: i)Flow occupancies and speeds on the mainline merge section of freeway were shown to be a big difference depending on the peak periods areas and directions based on the distribution of traffic flow characteristics on the freeway. ii)Reduced speed was shown to be more than 5 mph and ramp flow was also shown to be more than 240 vph at peak periods if there was the ramp metering system constructed on the freeway. iii)Ramp metering system was shown to be optimally operated on the freeway if ramp flow could be maximized within the range of over 900 vph and reduced occupancy could be also maximized by no more than 2 percent at peak periods. iv)The average flows on the freeway after the ITS technology were shown to be a decrease of over 20% depending on the peak periods areas and directions when compared with those flow on the freeway before the ITS technology. over 20% depending on the peak periods areas and directions when compared with those speeds on the freeway before the ITS technology. vi)The average metering rates on the freeway after the ITS technology were shown to be an increase of over 10% depending on the peak periods areas and directions when compared with those metering rates on the freeway before the ITS technology.

This study explored the role and characteristics of music that contributed to experiences of catharsis in music. An empirical phenomenological study was conducted to explore catharsis with 12 adults. Phenomenological reduction, change of attitude, literature interpretation, and hermeneutic circle were used for data collection and analysis. As a result, three categories, five themes, and 11 sub-themes were identified. The first category, here and now in music consisted of two themes: aesthetic experiences and expansion of musical novelty. The second category, inner connection through music consisted of one theme, re-experience of internal emotions. The third category, immersion and engagement in music consisted of two themes: ventilating or deepening of emotions and internal dynamics. Based on these results, the cathartic characteristics of music are discussed. First, the aesthetics and novelty of music kept participants fully stay in music. Second, music induced a re-experiencing of emotions by triggering memories or stimulating unresolved emotions. Third, the elements of music promoted emotional ventilation, deepening, and internal dynamics. This study is meaningful because it qualitatively examined the roles and characteristics of music that contribute to cathartic experience in the general adult population.

Because of various societal changes, such as the recent improvement in income levels and extension of the flexible work system, the demand for forest recreation activities and their use patterns are undergoing a change. Accordingly, it is necessary to identify the characteristics of each type through the segmentation of the overall forest recreation and welfare markets and to plan differentiated policies for each market type. This study classifies the forest recreation and welfare activities according to four types of users (i.e., passive usage type, ordinary type, active lover type, and indifferent type) using the Latent Class Analysis and examines their demographic and socioeconomic characteristics to explain the differences between the groups. Three policy implications were derived from the results obtained: 1) the group experiencing forest recreation welfare is subdivided; 2) the socioeconomic characteristics that distinguish the groups undertaking forest recreation activities were identified; and 3) the policy targets and characteristics that can increase the experience of forest recreation welfare were identified. This study is insightful as it suggests differentiated policies for each group and proposes policy measures to move to the desirable group.

Large-scale earthquakes are occurring globally, especially in the South Asian crust, which is experiencing a state of tension in the aftermath of the 2011 East Japan Earthquake. Uncertainty and fear regarding the possibility of further seismic activity in the near future have been on the rise in the region. The National Disaster Management Research Institute has previously studied and analyzed the overflow characteristics of a tsunami and the rate of flood forecasting through tsunami numerical simulations of the East Sea of South Korea. However, there is currently a significant lack of research on the Southern Coast tsunamis compared to the East Coast. On the Southern Coast, the tidal difference is between 1~4 m, and the impact of the tides is hard to ignore. Therefore, it is necessary to analyze the impact of the tide propagation characteristics on the tsunami. Occurrence regions that may cradle tsunamis that affect the southern coast region are the Ryukyu Island and Nankai Trough, which are active seafloor fault zones. The Southern Coast has not experienced direct damage from tsunamis before, but since the possibility is always present, further research is required to prepare precautionary measures in the face of a potential event. Therefore, this study numerically simulated a hypothetical tsunami scenario that could impact the southern coast of South Korea. In addition, the tidal wave propagation characteristics that emerge at the shore due to tide and tsunami interactions will be analyzed. This study will be used to prepare for tsunamis that might occur on the southern coast through tsunami hazard and risk analysis.

The contemporary age is a period of PR for the self. Regardless of how good the quality of goods or services offered is, if it is not made known to the buyers, a sell is impossible. As a result, the contemporary man is flooded with advertisements and is living in a time of over-saturated information. This is not much different in the medical services sector, as it too is experiencing an overflow of information due to the expansion of advertisement approaches to include not only the previous positive-method, but also the negative-method. In tandem, recent advancements in electronics and information technology has made possible a rapid increase in then number of internet advertisements. However, outmoded medical law, which was created to regulate newspapers and billboards, is still being applied to regulate today's modem medical advertisements. At the same time, collateral ordinances such as "corrective statutes for signs and advertisements" are not sufficient in providing the necessary regulatory countermeasures. In the midst of all this, as IPTV is scheduled to be broadcast nationwide starting next year, and with the market for search advertisements and internet advertisements annually growing at a rapid pace, it has become evermore urgent to come up with an adequate regulatory measure. Consequently, it is necessary to look into the possibility of restricting the medium and content of internet medical advertisements as well as realistic schemes for its realization. In particular, regulatory measures that take into consideration the special characteristics of internet advertisements should be found, and the necessity of an prior deliberation procedure and the likelihood of introducing a certification system should be examined.

Objectives : The multimodal telepresence systems have been adopted in a variety of applications, such as telemedicine, space or underwater teleoperation and videoconference. Multimedia, one of the telepresence systems, has been used in various fields including entertainment, education and communication. The degree of subjective telepresence is defined as the probability that a person perceives to be physically in the remote place when he/she experiences a multisensory feedback from the multimedia. The current study aimed to explore the neural mechanism of telepresence related to multisensory feedback in patients with schizophrenia. Methods : Brain activity was measured using functional magnetic resonance imaging while fifteen healthy controls and fifteen patients with schizophrenia were experiencing filmed referential conversation at various distances (1 m, 5 m and 10 m). Correlations between the image contrast values and the telepresence scores were analyzed. Results : Subjective telepresence was not significantly different between the two groups. Some significant correlations of brain activities with the telepresence scores were found in the left postcentral gyrus, bilateral inferior frontal gyri, right fusiform gyrus, and left superior temporal sulcus. There were no main effects of group and distance. Conclusion : These results suggest that patients with schizophrenia experience telepresence as appropriately as healthy people do when exposed to multimedia. Therefore, patients with schizophrenia would have no difficulty in immersing themselves in multimedia which may be used in clinical training therapies.

The purpose of this study was to investigate the characteristics and the current condition of musculoskeletal pain sufferers among fitness center users. The investigation used self-reporting questionnaire with the 797 subjects. On average, the subjects were 30.6 years old, 168.8 cm in height and 65.2 kg in weight. Among them, 423 were male (53.1%) and 374 were female (46.9%). Out of them, 276 suffered from pain, (35.2%). More men felt muscle aches than women (p<.05). In terms of pain, lower back area topped the list with 44.9%, followed by the lower extremities (30.1%), the neck (17.8%) and the upper part of the body (17.8%). Dieters suffered the most from pain (86.2%) while those exercising to build strength suffered the least with 26.8%. There was a significant relationship between the purpose for exercising and the amount of pain suffered (p<.05). By kind of exercise, pain stroke aerobic exercisers disproportionately with 42.4% while it almost steered clear of exercisers for strengthening with 26.9%. There was significant relationship between the kind of exercise and pain suffered (p<.05). The type of suffering differed by body shape. A significantly higher number of overweight people experienced pain than underweight people (p<.05). 32.8% of pain sufferers commented that the pain affects their workout, and on this issue there was no gender difference (p>.05). The pain caused more difficulties in doing activities of daily living for overweight or obese peoples than underweight peoples (p<.05). More than a third of health club and fitness center users are experiencing musculoskeletal pains. Measures such as professional training or information provision is required to prevent injury or disorder caused by improper exercise.

Objective: This study was to investigate the perception gap between preceptors and pharmacy students on community pharmacy experiential education. Methods: The online survey was performed for 55 preceptors and 215 pharmacy students separately from April 1 to April 30, 2014. The preceptors were who completed community pharmacy practice experience at least a session and the students were who involved in community pharmacy practice for more than 21 days. The questionnaires were prepared based on the lesson contents guideline of Introductory Pharmacy Practice Education of Community Pharmacy by Korea Association of Pharmacy Education. The survey questions were consisted with demographic characteristics, evaluation of student and preceptors, benefits and disadvantages of pharmacy practice for both groups. Results: A total of 27 (49.1%) preceptors and 103 (47.9%) pharmacy students responded to the survey questionnaires. Preceptors indicated that students lacked face-to-face communication ability with patients, caregivers, and physicians. One of the Benefits of participating in pharmacy practice education as a preceptor included the improvement of self-esteem (70.37%). Disadvantages were identified as workload burden due to teaching and preceptor responsibilities at the same time. All students responded that benefits of experiencing pharmacy practice education were helping them determine their career, and they would consider working in community pharmacies (68.93%). However, handling over-the-counter drugs and communicating with doctors or nurses were identified as barriers. In addition, preceptors and pharmacy students expressed necessity of the standard text books and curriculums. Conclusion: This study identified the perception gap on community pharmacy experiential education between preceptors and pharmacy students. For the successful implementation of pharmacy practice experience, the effective and appropriate methods should be developed.
