This study is a sustainability study of K-Music beyond K-Pop through New Media. New media literally means 'new media'. When TV, classified as legacy media, first appeared in the world, it was an innovative new media platform. Of course, it is considered the most traditional legacy media. However, the definition of new media inevitably changes with the times. Most of the media called new media today are based on online and mobile. This thesis focuses on popular music including crossover traditional music genre. And we define popular music exported abroad as K-pop, and propose the possibility of globalization of Korean music using K-pop users and new media, a metaverse based K-pop audition platform, as consumers and suppliers in the global market. Hallyu, the studying of K-Pop through the study of attitudes and economic effects of K-pop, such as reactions to the spread of K-pop and the reactions of fans who like K-pop, are constantly being discussed in various ways. But there has been no case of cultural technology research that linked the sustainability of Gugak as the Korean music through new media to the K-pop business platform. As the overflowing data pours out in the virtual space as an act that gives the meaning of existence, the online is able to become an open market that provides reliable information all over the world. Therefore we would like to propose on the sustainability of Korean music through the 'Korean Traditional Music Broadcasting Metaverse Audition' beyond the K-pop business model as the K-Music content in the cultural technology era.

융합의 개념은 효율과 성능 개선 등을 목적으로 서로 다른 기술이나 산업분야가 결합함으로써 존재하지 않았던 새로운 기능이나 서비스를 창출하는 현상을 말한다. 우리가 사는 지금 이 시대는 기술의 비약적인 발달로 인해 컨텐츠 생산 및 소비 환경이 급격히 변화하고 있으며, 각 분야의 경계가 소멸하는 방향으로 진행되고 있다. 이는 음악에도 적용된다. 1969년 재즈 연주자 마일스 데이비스에 의해 재즈와 록음악의 융합이 시도되었고, 클래식 또한 예외는 아니었다. 장르간의 크로스오버를 통해 엄격하게만 연주되었던 클래식은 그 틀을 벗어나 새로운 형식으로 거듭나게 되었다. 이러한 추세는 전 세계적으로 확산되었으며, 한국에서도 여러 뮤지션들에 의해 크로스오버가 시도되었다. 본 논문에서는 대중음악의 편곡기법을 활용하여 클래식 음악을 연주한 사례로, 1979년에 발표된 사랑과 평화 1집에 수록된 <여왕벌의 비행>, <베에토벤의 운명> 두 곡을 선정하였다. 각각의 곡은 원곡의 악보와 함께 나열하고 클래식과 훵크의 특징을 리듬섹션을 중심으로 분석하였다.

This study aims to find out the effect of ingestion of 3 mg·kg^-1 caffeine on fluid-electrolyte balance and Tty change during exercise under heat environment of 30~32℃ (40-50% humidity). Five trained males who routinely trained for approximately 60 min·d^-1, 3-6 d·wk^-1 (age; 28.20±3.56yrs, height; 174.56±5.46 cm, body mass; 76.13±9.02 kg, body fat(%); 14.24±3.99, VO₂max; 54.00±4.30 mL·kg^-1·min^-1, exercise career; 4.20±1.95yrs) performed 40min of treadmill running in heat chamber. The study was a double-blind, randomized, crossover design. Body mass change following exercise was higher for the PLAC (Placebo) and CAFF (Caffeine) in comparison to the CON (Control), there was no significant difference between the CAFF, PLAC, CON (p= .997). The U_sg not significant differences (p= .731) and Osm_urine not significant differences between the CAFF, PLAC, CON (p= .901). There also were not significant between the CAFF, PLAC, CON for [Na⁺]_urine and [K⁺]_urine (p= .928, p= .469). In the case of Tty, although the increase rate of Tty was the highest for the CAFF on exercise early, exercise the second half in comparison to the CON and PLAC, there was not significant interaction effect between the CAFF, PLAC, and CON of Tty (p= .067), In conclusion, it was confirmed that the 3 mg·kg^-1 caffeine ingestion prior to exercising in heat environment does not impart negative effect on body fluid, electrolyte balance and changes in Tty.

Objectives: We investigated whether asthma attacks in asthmatic children were caused by short-term exposure to particulate $matter(PM)_{2.5}$. Methods: Subjects were 411 patients who received inhalation therapy in National Fukuoka Hospital, from March to May 2013. All subjects were outpatients. We surveyed the air quality measurement results in the stations closest to the address of the patients. Data were used from the City of Fukuoka website data on air pollution. We carried out a case-crossover study and compared $PM_{2.5}$ concentration between 7 days after asthma attack occurred and the day asthma attack occurred and 1, 2 and 3 days before asthma attack occurred. Results: Highest hourly concentration of the day (OR 1.013, 95%CI 1.000-1.025) showed a significant association with 1 day before $PM_{2.5}$ concentration statistically. And 0-1 year-old infants were more vulnerable to the highest concentration of 1 day before $PM_{2.5}$ concentration(P < 0.05). Average concentration of $NO_2$ and $O_3$ and asthma attack also showed a significant association. Conclusions: Maximal daily $PM_{2.5}$ concentrations within 24 hours prior to the attack affect asthma exacerbation. 0-1 year-old infants are particularly vulnerable to $PM_{2.5}$ concentration. Asthma exacerbation is aggravated by $NO_2$ and $O_3$ concentration on the day of the asthma attack.

최근 한반도에서도 크고 작은 지진이 발생하여 더 이상 한국은 지진 안전지대로 볼 수 없으며, 특히 큰 규모의 지진 발생이 잦은 주변국의 영향으로 인해 발생할 수 있는 지진해일에 대한 신속한 대응이 필요하다. 지진해일의 발생은 큰 인명피해를 초래할 수 있으므로 지진 발생에 대비하여 대피소의 위치를 선정하는 것은 매우 중요한 일이다. 기존에 대피소 관련 연구가 다양하게 진행되었지만, 사용한 자료는 대부분 대피소 주변의 정적인 정주인구를 바탕으로 분석되어 현실성이 결여되어있다. 본 연구에서는 긴급상황 발생 시 현실성을 반영하기 위해 유동인구 데이터를 사용하였고, 대피소 위치선정에 다수 활용되고 휴리스틱 알고리즘 중 좋은 결과를 도출해내는 유전자 알고리즘을 이용하였다. 선택, 교차, 변이 과정을 통해 대피 가능 인원을 유전자 알고리즘의 목적함수로 사용하여 최적지를 탐색하였으며, 연구지역으로 선정한 부산 해운대구를 중심으로 연구한 결과, 총 8개의 대피소를 설치하는 것이 가장 효율성이 높은 것으로 최종 도출되었다. 최종 선정된 대피소의 위치는 일반거주지역뿐만 아니라 주요 관광지 주변도 선정되었는데, 이는 정주인구 통계자료만으로는 도출될 수 없는 결과로 본 연구를 통해 유동인구 데이터 활용의 중요성을 확인하였다.

Objectives : The purpose of this study is to assess the effect of Taegeuk acupuncture on reducing mental stress by analyzing heart rate variability in Soeumin. Methods : Six Soeumin-diagnosed men participated in this study. They were randomly divided into group A and group B. Each participant went through 4 sessions every week with 1 week of washout period in between each session. HRV was measured three times at every session; at baseline, after administering mentally stressful circumstances and after applying Soeumin Taegeuk acupuncture or Soyangin Taegeuk acupuncture. This study was designed as a crossover clinical trial. Group A participants were treated with two sets of Soeumin Taegeuk and Soyangin Taegeuk acupuncture treatment in respective order (i.e. Soeumin Taegeuk - Soyangin Taegeuk - Soeumin Taegeuk - Soyangin Taegeuk acupuncture treatment). Group B participants were treated with reverse-ordered acupuncture treatment (i.e. Soyangin Taegeuk - Soeumin Taegeuk - Soyangin Taegeuk - Soeumin Taegeuk acupuncture treatment ). Bayesian analysis was performed by using WinBUGS(Ver. 1.4.3) for comparison between Soeumin Taegeuk acupuncture and Soyangin Taegeuk acupuncture. Results : Overall, Soeumin Taegeuk acupuncture tends to reduce LF/HF ratio, LF, HF, LF(Norm) and increase HF(Norm) more than Soyangin Taegeuk acupuncture, but the difference was not statistically significant. In one participant, however, Soeumin Taegeuk acupuncture reduced LF/HF ratio, LF(Norm) and increased HF(Norm) more than Soyangin Taegeuk acupuncture, and the difference was stastatistically significant. Conclusions : This study suggests that Soeumin Taegeuk acupuncture might be an effective means of stabilizing mental stress-induced imbalance of autonomic nervous system for Soeumin.

There seems to be a consensus among most people that visibility impairment is the most obvious indicator of air pollution. While considerable evidence on the association between air pollution and health outcomes including death and disease have been established, based on industrial complex areas or huge urban cities, time-series, case-crossover and cohort studies, scarce literature exists on the direct evidence for the association between visibility and adverse health outcomes. Our study is assessed the effect of air pollution measured by visibility impairment on respiratory mortality over a period of six years. Relative risks in respiratory deaths were estimated by a Poisson regression model of daily deaths between $1999{\sim}2004$. Daily counts of respiratory deaths as dependent variable was modelled with daily 24-hr mean visibility measurements (kilometers) as independent variable by means of Poisson regression. This model is controlled for confounding factors such as day of weeks, weather variables, seasonal variables and $PM_{10}$. The results in this study is observed the statistically significant association between an inverse health effect and visibility during the study period for respiratory mortality (percentage change in the relative risk for all aged -0.57%, 95% Cl, $-1.01%{\sim}-0.12%$; for $0{\sim}15$ aged -7.12%, 95% Cl, $-13.29%{\sim}-0.51%$; for 65+ aged -0.43%, 95% Cl, $-0.93%{\sim}-0.06%$ per 1 km increased in visibility). The effect size was much reduced during warm season. Visibility impairment resulting from air pollution is strongly associated with respiratory mortality, especially for children may be spent at outdoor. Our result provides a quick and useful indicator for eliciting the contribution of air pollution to the excess risk of respiratory mortality in Seoul, Korea.

최근 대피시설의 위치 적절성, 수용 능력 등을 분석하기 위한 연구가 다양하게 진행되고 있으나, 신규 대피시설의 위치를 선정하는 방법에 관한 연구는 상대적으로 부족하다. 만일의 사태에 대비하기 위해서 대피시설을 지정하는 것이므로, 효율적으로 대피시설의 위치를 선정하는 방법 또한 필요하다. 따라서 본 연구에서는 대피시설의 입지 적절성 분석에 활용되어온 네트워크 분석과 대표적인 휴리스틱 알고리즘인 유전자 알고리즘을 활용하여 대피시설의 위치를 선정하는 방법을 제시하였다. 먼저, 기존의 민방위 대피시설 자료를 토대로 네트워크 분석을 시행하여 연구지역의 대피 취약지를 살펴본 결과, 지역별로 편차가 큰 것을 확인할 수 있었다. 이에 연구지역의 대피 취약지를 최소화하는 것을 목적함수로 유전자 알고리즘을 설계하여 신규 대피시설의 위치를 결정하였다. 대피시설 후보지의 위치로 구성된 초기해를 무작위로 생성하였고, 선택, 교차, 변이의 과정을 통해 목적함수를 최대로 만족하는 해를 탐색하였다. 실험결과, 연구지역 내 대피 취약지역의 비율이 높은 곳이 우선적으로 선정되었으며, 제안 기법의 효용성이 확인되었다. 본 연구의 결과는 향후 새로운 대피시설의 위치를 지정하고 효율적인 대피 계획을 수립하는 데에 기여할 수 있을 것으로 기대된다.

Objectives : We evaluated the risk of fracture associated with hypotension-related adverse drug reaction caused by taking alpha blockers to treat benign prostatic hyperplasia (BPH). Methods : We used the Health Insurance Review and Assessment Service database from January 1st 2005 to June 30th 2006 for this study. The male patients with BPH and who had a prescription for alpha blockers following any fractures were defined as the cases. We set the 20 day long hazard period prior to the index date and the four control periods whose lengths were same with hazard period. After 1:4 matching of the hazard and control periods, conditional logistic regression was used to calculate the odds ratios for the risk of fractures as related to the alpha blocker exposure. Results : Doxazosin and tamsulosin showed the increased risk of fractures, whereas terazosin did not. After stratification using the defined daily doses, a protective effect was shown for the patients who took terazosin at the doses lower than 0.4 DDD and the hazardous effect at the doses higher than or equal to 0.4 DDD. There was no significant difference for the risk of patients taking tamsulosin at the doses higher than 1.0 DDD but there was a statistically significant increase in the risk at the doses higher than or equal to 1.0 DDD. Conclusions : Alpha blockers for BPH may increase the risk of fracture in elderly patients who have comorbidities and take the concomitant medications. Alpha blockers need to be prescribed with caution, although some have high prostate specificity.
