The development of information and communication technology and the improvement of the development and dissemination of smart devices have caused changes in the form of tourism, and the concept of smart tourism has since emerged. In this regard, researches related to smart tourism has been conducted in various fields such as policy implementation and surveys, but there is a lack of research on application reviews. This study collects Trip Advisor application review data in the Google Play Store to identify usage of the application and user satisfaction through Latent Dirichlet Allocation (LDA) topic modeling. The analysis results in four topics, two of which are positive and the other two are negative. We found that users were satisfied with the application's recommendation system, but were dissatisfied when the filters they set during search were not applied or that reviews were not published after updates of the application. We suggest more categories can be added to the application to provide users with different experiences. In addition, it is expected that user satisfaction can be improved by identifying problems within the application, including the filter function, and checking the application environment and resolving the error occurring during the application usage.

Objectives : As the side effect brought up by internet game addiction, many reports come out, but most of past articles are for middle or high school students. There is seldom a poisoning game treatise to a primary school student, if there is treatise, it is real condition that treatise for lead pipe with psychological reasons is seldom discussion about physical symptoms. This research searches high grade elementary students' game use actual conditions and when divide to general user group, latent danger use group, high dangerous use group, according to serious illness degree of game poisoning, three groups and game poisoning happens, recognized about body symptoms that happen much. Methods : Target population of these questionnaire are fifth and sixth grade elementary student of Seoul city 2 school. Chose 263 elementary students, 144 men, 119 women who understand purpose of research and admit participation is 25 October, 2006 since 1 September, 2006 Results : As poisoning serious illness degree is high, there are many number of game times, much more boys are addicted to internet game than girs, insomnia is apt to happen frequently in game poisoning danger group, and correlation is high by megrim, shoulder ache, digestive trouble. Insomnia, symptoms that show next even if some symptoms show first because there is high correlation between megrim, shoulder ache, digestive trouble is high possibility to happen among four symptoms. Insomnia, megrim, shoulder ache, digestive trouble that happen by internet game poisoning, is apt to increase by increasing addiction. Symptoms treatment can divide by internal treatment that treat insomnia, megrim, digestive trouble, external treatment that is typical symptoms of VDT syndrome shoulder ache, headache, fatigue persimmon. Root treatment is mind symptoms treatment. Game addiction treatment is relationship method 'seven emotions injury treatment' in oriental medicine. 'promote the normal flow of qi' and 'adjustment of suitable emotion' can talk as pivotal point of treatment.

The PingMaiFa chapter, which is the second chapter of SongBon ShangHanLun, is the scholarly description(專論) of the pulse and pathological mechanism but has not been studied and published yet. This study is about article 1-13 which is the first part of The PingMaiFa chapter. We compared the original texts within the editions, comparing and analyzing the annotations of successive dynastic medical group. The articles of The SongBon ShangHanLun PingMaiFa chapter 1-13 is consisted as is shown: article 1 states about the general features of normal pulse (平脈) and its physiological mechanism and the morbid pulses (病脈) caused by wind, cold, retained fluid, pain and heat vexation, article 1,10 state about the normal pulses of Five viscera (lung, heart, spleen, liver and kidney) and their manipulations in pulse taking, article 2 states about the differentiations of deficiency and excess syndrome according to pulse conditions, article 3, 4 state about the estimation of good prognoses and a factitious disorder by the combination of pulses and symptoms, article 6 states about Latent qi (伏氣) and its diagnostic features, article 5 states about inspection and listening examination as co-diagnostic methods of the pulse diagnosis, article 7, 8, 9 state that the emotions, such as fear and shame, and the dietary are important factors to consider for making diagnosis, article 11 states about the overwhelming pulse (相乘脈) which indicates the abnormal correlations between five phases and appears in four patterns as the dissolute(縱), the unrighteous(橫), the unfavorable(逆) and the favorable(順), article 12 states about 6 harmful pulses(殘賊脈), which are string-like pulse(弦脈), tight pulse(緊脈), floating pulse(浮脈), slippery pulse(滑脈), sunken pulse(沈脈), rough pulse(澁脈), article 13 states about "JaeGoe"(災怪) which is an unexpected response after treatment and it comes because of the formulas that had before. Throughout all these articles, The PingMaiFa chapter not only offers great value for Pulse-taking diagnosis, but also leads to a better understanding of clinical applications.

Monthly mean surface heat fluxes in the southeastern Yellow Sea are calculated using directly observed airsea variables from an ocean buoy station including short- and longwave radiations, and COARE 3.0 bulk flux algorithm. The calculated monthly mean heat fluxes are then compared with previous estimates of climatological monthly mean surface heat fluxes near the buoy location. Sea surface receives heat through net shortwave radiation ($Q_i$) and loses heat as net longwave radiation ($Q_b$), sensible heat flux ($Q_h$), and latent heat flux ($Q_e$). $Q_e$ is the largest contribution to the total heat loss of about 51 %, and $Q_b$ and $Q_h$ account for 34% and 15% of the total heat loss, respectively. Net heat flux ($Q_n$) shows maximum in May ($191.4W/m^2$) when $Q_i$ shows its annual maximum, and minimum in December ($-264.9W/m^2$) when the heat loss terms show their annual minimum values. Annual mean $Q_n$ is estimated to be $1.9W/m^2$, which is negligibly small considering instrument errors (maximum of ${\pm}19.7W/m^2$). In the previous estimates, summertime incoming radiations ($Q_i$) are underestimated by about $10{\sim}40W/m^2$, and wintertime heat losses due to $Q_e$ and $Q_h$ are overestimated by about $50W/m^2$ and $30{\sim}70W/m^2$, respectively. Consequently, as compared to $Q_n$ from the present study, the amount of net heat gain during the period of net oceanic heat gain between April and August is underestimated, while the ocean's net heat loss in winter is overestimated in other studies. The difference in $Q_n$ is as large as $70{\sim}130W/m^2$ in December and January. Analysis of long-term reanalysis product (MERRA) indicates that the difference in the monthly mean heat fluxes between the present and previous studies is not due to the temporal variability of fluxes but due to inaccurate data used for the calculation of the heat fluxes. This study suggests that caution should be exercised in using the climatological monthly mean surface heat fluxes documented previously for various research and numerical modeling purposes.
