This study suggests a method for making a system of basic materials for the restoration of the 3X3 Kan central hall remains of a Buddhist temple from the Joseon Dynasty. Because there are both an extant hall and remains from the Joseon Dynasty, the basic material can be constructed through comparison with the floor plan. Multi-step comparisons were found to be the most suitable example for restoration. For this study, five parts of the 3x3 Kan remains were compared with 70 extant halls for a case study. For the first comparison, the limit of collection makes four examples in the whole examples. There are many relationships with the area and the length ratio of the front to the side as the comparison articles, so there are examples that satisfied both comparison articles. However, there is little relationship between the length ratio of the front Eokan to the front Hyeopkan and the length ratio of side Eokan to the side Hyeopkan. The construction method of the basic material shows the possibility of expansion with various directions that have pros and cons.

According to the expansion of the Internet use and the utilization of e-business, there are an increasing number of studies of intelligent-based systems for the preparation of ubiquitous environment. In addition, expert systems have been developed from Stand Alone types to web-based Client-Server types, which are now used in various Internet environments. In this paper, we investigated the environment of development for web-based expert systems, we classified and analyzed them according to type, and suggested general typical models of web-based expert systems and their architectures. We classified the web-based expert systems with two perspectives. First, we classified them into the Server Oriented model and Client Oriented model based on the Load Balancing aspect between client and server. Second, based on the degree of knowledge and inference-sharing, we classified them into the No Sharing model, Server Sharing model, Client Sharing model and Client-Server Sharing model. By combining them we derived eight types of web-based expert systems. We also analyzed the location problems of Knowledge Bases, Fact Bases, and Inference Engines on the Internet, and analyzed the pros & cons, the technologies, the considerations, and the service types for each model. With the framework proposed from this study, we can develop more efficient expert systems in future environments.

Nous distinguons l'image-mouvement et l'image-temps qui sont les $cat{\acute{e}}gories$ essentielles chez $Cin{\acute{e}}ma$. C'est surtout sur ce point que nous insistons. Dans ce cas, nous discutons aussi de la question des spectateurs du film qui conduit. Cette question permet susciter de la $mani{\grave{e}}re$ $d^{\prime}{\hat{e}}tre$ des spectateurs entre le film qui est $compos{\acute{e}}$ de l'image-mouvement dont G.

The aim of this study was to analyze the levels of learners' participation and interactions both quantitatively and qualitatively based on the learners' choices of topic patterns in a process of online debate of a general subject and to explore the effects in order to suggest the ways for activating online debates. For this, it quantitatively analyzed the messages and the patterns in the online debate boards and supplementally implemented a post survey in order to investigate the participants' recognition on the factors of the learners' interactions and the effects. The given topic patterns were 'the presentation of one's opinion' and 'the presentation of pros and cons.' As a result of the analysis, the participating degree was higher in the pattern of 'the presentation of one's opinion' apart from the previous study. This study surveyed and, based on the result, it proposed the teachers should refer to the participants' tendency in advance. Also, it presented the deeper meanings on the interactions extracted by the results of the survey. The learners showed the strong dependence on the teacher' lectures or his materials and a variety of interactions with diverse objects. Besides, it is revealed that debates are helpful factors for enhancing learners' argumentative thinking, writing skills, and the knowledge about the subject in terms of the participants' recognition. Based on the findings, this study emphasized the teachers' educational roles and suggested the educational effects of the online debates in each class should be activated in this era of distance education.

This research suggests video solutions and efficient implementations for low-budget performances. This study adopts Millumin as a mapping server, which reflects the character of small theatres with a lower budget that doesn't use more than four projectors in a show. By comparing pros and cons of media servers, the study discovers how to employ an appropriate server as well as to participate in a pre-video production stage, which increases the artistry of directing and reduces unnecessary graphics. Meanwhile, with the participation of an interpretive programmer, this study suggests a way to manage the rehearsal time and to increase the artistry of directing. In addition, this study analyses the relationship between the video's visual motive source in the story's development, crisis, climax, twist and the provided narrative based on "Trace U the musical (2018)", by this analyzation, the relationship between storytelling and the video is fully shown. A visual motive is related to the action of actors, the movement of dancers, the music, the lyrics and the lines. Furthermore, the provided narrative confirms that the existence of an actual relationship with the turning point of the plots, characters' emotion, suggestions of sub-plot and the twists of own story. In conclusion, it implies a video of small theatres can not be separated from the probability of the narrative.sh an efficient ad execution strategy that reflected the characteristics of mobile devices.

The purpose of this study is to investigate the opinions of non-health science college students of Korean dental hygienists in the category of medical personnel. A self-reported questionnaire was conducted on 265 non-health science major students without information about a health and medical service personnel. The collected data were analyzed using frequency, percentage, descriptive statistics, chi squared and multinomial logistic regression analysis. About 40% of the respondents answered that dental hygienists should be medical personnel, while 17.7% think that they should not distinguish health and medical service personnel between medical personnel and medical service technologist. As the respondents' oral health management ability improved, they approves the Korean dental hygienists in the category of medical personnel(p=.022). As the longer the period of dental regular visits, they answered that dental hygienists should be medical service technologist. Presence or absence of dental regular visits, scaling experience, oral health education did not no significant difference on the opinions of Korean dental hygienists in the category of medical personnel of the pros and cons. This study can be used as a basic data for establishing the policy of medical personnel for dental hygienists.

Today, with the spread of smartphones and the development of social networking services, structured and unstructured big data have stored exponentially. If we analyze them well, we will get useful information to be able to predict data for the future. Large amounts of data need to be collected first in order to analyze big data. The web is repository where these data are most stored. However, because the data size is large, there are also many data that have information that is not needed as much as there are data that have useful information. This has made it important to collect data efficiently, where data with unnecessary information is filtered and only collected data with useful information. Web crawlers cannot download all pages due to some constraints such as network bandwidth, operational time, and data storage. This is why we should avoid visiting many pages that are not relevant to what we want and download only important pages as soon as possible. This paper seeks to help resolve the above issues. First, We introduce basic web-crawling algorithms. For each algorithm, the time-complexity and pros and cons are described, and compared and analyzed. Next, we introduce the state-of-the-art web crawling algorithms that have improved the shortcomings of the basic web crawling algorithms. In addition, recent research trends show that the web crawling algorithms with special purposes such as collecting sentiment words are actively studied. We will one of the introduce Sentiment-aware web crawling techniques that is a proactive web crawling technique as a study of web crawling algorithms with special purpose. The result showed that the larger the data are, the higher the performance is and the more space is saved.

Cancer is genetically, metabolically and infectiously induced life threatening disorder showing aggressive growing pattern with invasive tendency. In order to prevent this global menace from jeopardizing human life, enormous studies on carcinogenesis and treatment for chemotherapy resistance have been intensively researched. Hinokitiol (${\beta}$-thujaplicin) extracted from heart wood of cupressaceous is a well-known bioactive compound demonstrating anti-inflammation, anti-bacteria and anti-cancer effects on several cancer types via apoptosis and autophagy. This study proposed that hinokitiol activates transcription factor EB (TFEB) nuclear translocation for autophagy and lysosomal biogenesis regardless of nutrient condition in cancer cells. Mitophagy and ${\beta}$-catenin translocation into the nucleus under treatment of hinokitiol on non-small cell lung cancer (NSCLC) cells and HeLa cells were investigated. Hinokitiol exerted cytotoxicity on HeLa and HCC827 cells; moreover, artificially induced autophagy by overexpression of TFEB granted imperfect sustainability onto HeLa cells. Taken together, hinokitiol is the prominent autophagy inducer and activator of TFEB nuclear translocation. Alternative cancer therapy via autophagy is pros and cons since the autophagy in cancer cells is related to prevention and survival mechanism depending on nutrition. To avoid paradox of autophagy in cancer therapy, fine-tuned regulation and application of hinokitiol in due course for successful suppressing cancer cells are recommended.

The identity of public libraries in Japan is a social education institution under the 「Social Education Act」 and the 「Library Act」. For these identities, the local government's board of education has operated and managed public libraries, and some have managed by the Management Outsourcing System to public organizations. Then, in 2003, the 「Local Autonomy Act」 was revised to introduce the Designated Manager System in form of administrative disposition, and expanded the scope of application to private institutions and organizations. As of the end of 2018, 18.0% of public libraries introduced the DMS, but the pros and cons surrounding it are sharply opposed. This study outlined the overall status of the DMS and the introduction of public libraries, and critically reviewed major issues. As a result, As a result, there was much controversy over the expected cost reduction, service improvement, employee professionalism, business continuity, and cooperation network establishment when DMS was introduced. The reasons were due to downsizing-based personnel management, contract-oriented employment, short periods of designation, lack of multiple competitive markets, and declining service capabilities of irregular workers. The public library is a knowledge and cultural infrastructure that enhances human values and social dignity based on faithful collection and active service, and is a local public goods that emphasizes non-exclusion and non-competitiveness. Given the increasing number of cases in which public libraries are recently contracting out to cultural foundations in Korea, DMS is not a fire across the river. We need to be wary of the possibility that Japan's unbearable institutional lightness will be applied to public libraries in Korea.

The authors had presented two previous papers[1,2] on Helicopter/Rotorcraft develoment in Europe and US. Meanwhile, the next generation rotorcrafts, currently under development in US and Europe, have new configurations (tilt-rotor, coaxial, compound) of rotor-type vertical takeoff/landing rotorcrafts to overcome the disadvantages of traditional helicopters. For developing these new types of rotorcrafts, the upgraded conceptual design/comprehensive programs are required. In US and Europe, they are already developing new program tools with their technologies and database obtained during more than last half centuries. For us, many academia, research institutes and industrial engineers have experienced and developed core technologies on rotorcrafts (aerodynamics, structural analysis, flight dynamics, and noise analysis etc.) comparable to US and Europe during last couple of decades of developing helicopters and various configurations of rotorcrafts. In this paper, the pros and cons of conceptual design/comprehensive tools currently used in US and Europe have been summarized. Furthermore, the possibilities and problems to develope our own design and analysis tools have been studied.
