As the individual participation in online news sites proliferates, the importance of online news comments has been increasing. Social comment services which help people leave comments on news articles using their own SNS (social networking site) accounts have gained popularity recently. Using data gathered from an online news site, this study, therefore, (1) identifies factors differentiating social comments from general comments, (2) examines how social comments are significantly different from general comments in terms of each factor, (3) and further validates how the social comments' characteristics vary among different type of SNS. Then, we investigated this study by applying t-test, ANOVA, and Duncan test of SPSS Statistics. Our results provide insights on the significant differences in all the factors between general and social comments. We also found that there is a significant difference between Facebook and Twitter groups among three types of SNS. The findings of this study would help assess the actual benefit of social comment services as they may provide us with several valuable leads to solve the malicious comments issue. Moreover, they would suggest the need to apply this service to other areas, such as online environments in private and public sectors.

Summary. Most of American pop music, which are dominating the hegemony of the global pop music market, have been derived from the culture of African Americans, most of whom were slaves of European immigrants. The music of black slaves must be the one of the greatest undisputed achievements that have most influenced the American history. Indeed, All of the mainstream pop music works around the world, including those in America, are the descendants of the black music with the gene of the black people. We can say, therefore, the music born through the Afro-American culture has become the music that every person around the world enjoys in the present. Accordingly, K-Pop music culture, centered in idol group, is also based on the black music. This fact suggests that the K-Pop culture can be spread into people in different customs or traditions with little resistance. The success factor of Motown, at the very center of the black music, which integrated the whole global music, is not only their incredibly outstanding music works, but also the self-consciousness the musicians have that they are strongly reluctant to settle down to present reality. This shall lead to the necessity of self-reflection for the Korean music market, which are obsessed with present popularity and only taking advantage of teenager market, and for those engaged in music business in Korea, who are lack of the artistic value and the consciousness as artist.

This Study has limited our scope to the study of satisfaction factor. Due to the extensiveness of fun factors of games. We had identified satisfaction factors through investigating various theories based on funology. Then, we have directly applied the satisfaction factors to games in order to define the satisfaction factors of online FPS game. Then, we have applied the satisfaction factors on to four online games, at the first phase of the study. We interviewed a group of online FPS game experts to identify the constituent elements of the factors and concluded the second phase of our investigation based on the results from the first and second phases, we have conducted a survey to verify the hypothesis. We have verified the reciprocal relationship between the satisfaction factors and game popularity by conducting a multiple regression analysis on the survey results. To conclude, there is a correlation between online FPS games and the satisfaction factors; the satisfaction factors cause the users to be absorbed into the game and to enjoy it for a long period of time.

Since a movie is an experience goods, purchase can be decided upon preliminary information and evaluation. There are ongoing researches on what impact online reviews might have on movie revenues. Whereas research in the past was focused on the effect of online reviews. The influence of online reviews appears to be significant in products like a movie because it is difficult to evaluate the feature prior to "consuming" the product. Since an online review is regarded to be objective, consumers find it more trustworthy. Contrary to prior research focused on movie review ratings and volume, we focus moves on movie features related specific reviews. This research proposes a predictive model for movie revenue generation. We decided 15 criteria to classify movie features collected from online reviews through the online review mining and made up feature keyword list each criterion. In addition, we performed data preprocessing and dimensional reduction for data mining through factor analysis. We suggest the movie revenue predictive model is tested using discriminant analysis. Following the discriminant analysis, we found that online review factors can be used to predict movie popularity and revenue stream. We also expect using this predictive model, marketers and strategic decision makers can allocate their resources in more parsimonious fashion.

Nowadays, short distance communication systems with low power energy (LPE) are developed for identification and monitoring of site identification of vessel crews and passengers (SIVCP). LPE communication modules, such as Bluetooth low energy (BLE) and Zigbee, are used for short distance communications with LPE. These modules enable 1:N communications and their popularity is growing since the modules can be mounted on movable objects, such as mobile devices and human body. When these modules are used, the important factor that affects their operation time and design are the capacity and size of battery. Therefore, they must be made as small as possible, and the battery should be selected to be slightly smaller than the module. In this study, we calculate the theoretical life of batteries used in SIVCP BLE modules using data sheet and discharge characteristic graph under the condition of a 1/250 transmission-ratio (TR). We thus calculate experimental life by measuring transmission current for the same TR, and low speed mode current for a 1/5000 TR and measure long-term experimental life using 1/25 TR for days. Through these experiments, we verify experimental methods for the prediction and extension of battery life that would enable us to select appropriate sizes of batteries based on vessel usage and passenger types. The selections of the module TR and battery size are important factors affecting the cost reduction of module design, the battery maintenance, and passenger convenience.

This study suggests a macroscopic method of evaluating forest recreation function based on physical characteristics of forests. The method was verified by a correlation between forest recreation function in popular top 45 mountains and popularity among them, with using data-mountain area, height, distance between mountain and cities, population around mountain, and size of public service. According to analysis of the forest recreation function, it is shown that top 8 mountains, including Jirisan and Seoraksan, provide over 64% of total recreation function, while they serve the function relatively lower than mountains near mega cities-Bukhansan in Seoul-do, in terms of the function per unit area ($km^2$). It is because, in a case of national and provincial mountains, the size of mountain is likely a critical factor for determining recreation function and the distance influences on it relatively lower. These findings implicate that a large size of forests bring the recreation function to visitors on nationwide level, whileas forests in suburban provide intensively it to near population to near population.

During the Joseon period, the East Sea would be called 'Gyeonghae' due to a large number of whales. In the Republic of Korea, whaling was locally permitted in 1946. However, the number drastically dropped because the hunting of the marine mammal had already been carried out in Russia, the U.S. and Japan since 1800s. Before a moratorium on commercial whaling was introduced by the International Whaling Commission(IWC) in 1986, whale populations in the East Sea had plunged. Furthermore, Korean gray whales and fin whales weren't found anymore in that area. With the suspension, whale hunting was banned in Korea as well. Even so, accidentally caught whales have been allowed to be distributed on the market with respect for local food culture. With the establishment of Whale Museum and hosting of the 57th Annual Meeting of the International Whaling Commission(IWC) at Jangsaengpo in 2005, whale tourism was facilitated in earnest. This whale tourism has been operated by Nam-gu Office and Nam-gu City Management Corporation in Ulsan. However, the popularity of whale tourism has increased a demand for whale meat. At the same time, there has been concern over decrease in whale populations because of illegal whaling. In addition, a conflict between the use and protection of whales has caused confusion in tourism identity. Actually, there is a serious doubt on the sustainability of whale tourism due to the decade-long deficit and excessive investments. This study attempts to define a concept of whale tourism and propose a future direction for the sustainable growth and development of Korea's whale tourism industry after developing such comprehensive assessment indicators as a basic research for the introduction of sustainable whale tourism. To achieve the aim of this study, AHP(Analytic Hierarchy Process) was chosen as a main research tool and the factors were ranked by a comprehensive analysis of principal factors and detail factors. The current study showed the following results. First, ecological environment(0.430) was indicated the most important factor of whale tourism assessment indicators. Moreover, Population(0.1302), Action for Cetacean protection(0.1031), Governance(0.0898) were critical factors. On the other hand, Accommodations(0.0085), Whale meat(0.0088) were unimportant factors than others.

Hanok (a traditional Korean-style house) has recently become a popular attraction for tourists all over the world. Jeonju Hanok Village, for example, attracted about 10 million visitors for 2 consecutive years. Observing Hanok's popularity, many local governments drew up plans to improve tourism dynamics by strengthening the advantages of Hanok. Emotionally rich experience is required to offer a greater satisfying experience that meets the demands of tourists. However, very few studies yet have addressed how to measure those emotions felt by users while experiencing Hanok. As an attempt to improve this situation, 182 emotional words were collected from earlier studies and classified into 33 groups with the Delphi method. Among the emotional words in each of the 33 groups, those of overlapping concepts on the characteristics of Hanok were re-grouped, and extracted the most appropriate 68 words. Additionally, a survey was conducted with 325 people who had experienced Hanok to gather 30-most representative emotions for measuring emotions felt from Hanok. The factor analysis of the 30 representative emotions resulted in classified 6 factors based on common features of emotional words: senses of aesthetics, happiness, novelty, ownership, balance and relaxation. The 30 representative emotions and six emotion categories found out by this study can help measure how much people feel certain emotions while experiencing hanoks. Further study will explore the degree of emotions hanok users feel about objects of hanok, such as roof materials and shapes, and body shapes.

Oocyte donation program developed to reach the pregnancy in those patients suffering from premature ovarian failure or surgery induced menopause, particularly in their reproductive age. With technical advances and popularity of ART (assisted reproductive technology), the indication of oocyte donation program extended to low responders, and even to naturally menopaused patients that has led them quite successfully to getting in pregnancy. The purpose of this study was to evaluate which one is involved in the decline of fertility between the oocyte and uterine factor. One hundred five cycles of oocyte donation program were performed in 84 patients from Jan., 1993 to Dec., 1996. Oocytes were donated from healthy, young, fertile anonymous donors or relatives or infertile patients with supernumerary oocytes. The study population was divided into 3 groups according to the age of recipients. Group 1 was less than 35 years old, Group 2 was between 35 to 39 years old, and Group 3 was more than 39 years old. The results were as follows: The mean age of oocyte donor was $31.5{\pm}3.3$ (range; 25-36). The mean concentration of basal serum FSH and peak serum estradiol were not different among groups. The mean number of oocytes retrieved from donors, embryos transferred to recipients, and fertilization rate were not different among groups. The clinical pregnancy rate was 37.3% in Group 1, 31.6% in Group 2, and 31.6% in Group 3, respectively. The spontaneous abortion rate was 16.0% in Group 1, 16.7% in Group 2, and 16.7 in Group 3, respectively. The multiple pregnancy rate was 20.0% in Group 1, 16.7% in Group 2, 16,7% in Group 3, respectively, The implantation rate was 11.3% in Group 1, 10.3% in Group 2 and 10.0% in Group 3, respectively. All of the pregnancy outcomes were not different statistically among groups. In conclusion, endometrial receptivity does not seem to be impaired as age increases with transfer of good quality embryos and adequate endometrial preparation.

Raquel, the representative work of Vicente García de la Huerta, an 18th century Spanish playwright achieved theater box-office success and popularity during staging. It has been evaluated by many scholars and critics as the ideal drama that faithfully followed the norms of neoclassicism, which pervaded the aesthetic mainstream at the time. However, the factor that enabled the popular success of this theater production was its ability to harmonize the themes or contents with a traditional play to meet the unique trends and tastes of Spanish viewers who were still appreciated earlier Baroque theater, rather than complying with external norms of neoclassicism such as principle of three unities or exclusion of comic figures etc. That is, Spanish viewers of the time thoroughly rejected theater of neoclassicists who attempted to unilaterally enlighten them while regarding the Baroque theater of earlier times as full of superstition and irrationality, illogic and disorder, regardless of their own dramatic taste. In this situation, Huerta's tragedy Raquel, achieved the harmony of neoclassical tragedy and Spanish theatrical tradition. It thus emphasizes the importance of public support and sponsorship in dramatic success. Traditional dramatic elements shown in Raquel can be summarized as honor, poetic justice and love and these elements are major dramatic codes penetrating the entire Baroque theater of Spain.
