The Korean government is attempting to promote technology-based start-ups and venture firms that can lead to new national growth engines being developed. Although government support policies focus on improving survival rates, strategic tools for sustainability management based on a continuing company's assumption are also relevant. Previous studies indicate corporate social responsibility (CSR) as an important strategic tool for the management of corporate sustainability. This research is an exploratory study that seeks to empirically analyze the applicability of such CSR to venture firms. Existing previous studies have been carried out by large companies and surveys, and there are limitations that do not reflect the characteristics of companies. To complement the shortcomings of previous studies and propose practical consequences, this study conducted an empirical analysis using raw data from government approval statistics to identify the growth stages of venture firms. Using the 2018 Survey of Korea Venture Firms, we identified the growth stages of domestic venture firms and used the data envelopment analysis (DEA) to investigate the effect of CSR activities on managerial efficiency. The analysis found that CSR during start-up and early growth cycles did not affect managerial performance. The organization that conducted enthusiastic CSR activities performed better than those that did not perform CSR activities since the rapid growth era. Ultimately, the scale efficiency of venture business was the highest from the rapid growth era when the CSR was not done. This study is a pioneering study that found that after the period of high growth, venture firms' CSR activities can affect managerial performance. Therefore, it is important to advise applicable policies and business decision-makers that CSR practices can be a tactical resource for improving performance of management.
This study was conducted to seek improvements by correcting problems of the qualification system of theatrical art technicians, which has a relatively weak foundation, compared to other national industrial qualifications. Through the previous researches, this study attempted to seek main issues and development plans in the field of theatrical art technology, while carrying out in-depth interviews for theatrical art technicians. With the results of this study, problems of the existing system can be largely divided into two kinds. Firstly, the existing system is mostly focused on performance places, especially large-sized public performance halls. Secondly, as a problem in terms of management, the existing system has non-professional management subjects and non-convenience regarding the number of qualification tests and places only in Seoul and once a year. This study grasped problems based on practical demands of the related industry through in-depth interviews with experts, thus seeking proper solutions. What matters most is that the present system should be converted from performance place-centered management to performance-centered management. In other words, by expanding qualification-acquired experts into all the performances, the system should practically contribute to improving the quality of performances and expanding the treatment of experts, which is the fundamental purpose of this system. Moreover, it is needed to seek a plan to expand the convenience of applicants for the procedures and methods of acquiring qualifications.

Gynura procumbens (Family Asteraceae) is a medicinal plant commonly found in tropical Asia countries such as China, Thailand, Indonesia, Malaysia, and Vietnam. Traditionally, it is widely used in many different countries for the treatment of a wide variety of health ailments such as kidney discomfort, rheumatism, diabetes mellitus, constipation, and hypertension. The objective of this study was to select the natural growth media for hydroponic cultivation of Gynura procumbens. The commercially available thirty four different organic nutrient solutions were analyzed for growing Gynura procumbens. After analysis, two organic nutrient solution were selected, mixed (pH 5.5~6.5 / EC 0.5~1.0 ds/m) and then used as organic fertilizers. Thirty day old seedlings were planted and the environmental conditions of the rhizosphere were also examined to select the natural media composition. The minimum temperature of rhizosphere by type of natural media was highest in cocopeat media and lowest in perlite media. Furthermore, plant growth was examined from 50 days old seedlings, and vermiculite was observed to be most effective and perlite was the least effective component as natural media. The total polyphenol content of the studied plant material was also higher in vermiculite in comparison to other growth media. The Gynura procumbens yields were also higher in vermiculite in comparison to other growth media. Thus, vermiculite can be used to improve Gynura procumbens plant growth as a natural growth media.

As the innovation of computer and communication technology, IT has played a role of increasing the business efficiency and offering new business opportunities. Many organizations have tried to launch IT projects, and the investment scale has been getting bigger. However, a lot of IT projects have been failed because of the difficulties of project management. Therefore, the purpose of this study is to know how the roles of project governance affect the project performance and what role of the project governance will be affected to solve the problems which might be taken place while developing the project. As the results of this study, the roles of project governance - linking, coordination, control, strategic direction, support, societal embedding, highly affect the project performance. To solve the problems which might be occurred while implementing the project, the control and the societal embedding roles playa crucial role compared to the other roles of the project governance. In other words, the roles of project governance should be utilized for the success of IT project, and the control and the societal embedding of the project governance should be modified and complemented to solve the problems which might be occurred while developing the project.

Water mains underground facilities are essential components to make up urban infrastructure. In order to manage these water mains underground facilities systematically and scientifically, GIS (Geographic Information System) had been constructed. For the sake of construction of GIS for water mains underground facilities, an exact underground detection and the construction of DB (Data Base) for buried water mains underground facilities should be preceded. In this study, in order to find out the ways to improve exact detection rate of data, the statistical analysis for the causes of detection raw degradation was done, and standardization methods of detection through a case study were suggested, When water mains underground facilities were measured, the detection of non-metallic water pipes was not carried out. The reason was that the results of detection was uncertain and detection was difficult because the assessment of public measurements was vulnerable. Moreover, due to the absence of standardized operating regulations for detection, systematic surveys weren't conducted. In this study, methods to standardize works over the detection of water mains underground facilities were presented so that we can improve the detection rate when we are doing that. As the proposals to improve detection rate, effective performance assessment over non-metallic pipes were presented, and related issues to supplement work regulations of public survey were described systematically.
The advancement of network & application technology causes a major change for the use of IT(Information Technology) equipment, including computer and mobile system. In the process from beginning with main frame in the 1960s and 70's, through the server-client paradigm in the 1980s and toward the development of network computer since 90's, computer systems are now evolutioning from isolated physical system to complementary network based virtual system[1][2]. In network based computer system, application and data required for operation are stored at not client as local system, but at server[1]. User can use application & data on a server as if those are on a local client, and a client is now toward a developing thin and network friendly system. In this paper, we discuss possible ways for the efficient implementation of thin-client. For the use of remote application & data as if in local environment, we make use of X protocol. Unlike formal simple Client - Server paradigm, we design a Proxy for middle-tier server for the improvement of QoS and session persistence. X server, Xvfb(X virtual frame buffer) are implemented on thin client and Server, respectively and we applied XSMP(X Session Management Protocol) to our framework for session management. In the end, beyond simple transfer of server display, we suggest thin client framework for the transfter of remote server application over internet.

Recently, recognizing user resource for personalized service has been needed in digital content service fields. Especially, to analyze user taste, recommend music and service music related information need recognition of user music file in case of online music service. Music related information service is offered through recognizing user music based on tag information. Recognition error has grown by weak points like changing and removing of tag information. Techniques of content based user music recognition with music signal itself are researched for solving upper problems. In this paper, we propose user music recognition on the internet by extracted feature from music signal. Features are extracted after suitable preprocessing for structure of content based user music recognition. Recognizing on music server consist of feature form are progressed with extracted feature. Through this, user music can be recognized independently of tag data. 600 music was collected and converted to each 5 music qualities for proving of proposed recognition. Converted 3000 experiment music on this method is used for recognition experiment on music server including 300,000 music. Average of recognition ratio was 85%. Weak points of tag based music recognition were overcome through proposed content based music recognition. Recognition performance of proposed method show a possibility that can be adapt to online music service in practice.
The aim of this study is to develop and construct the elements of a new evaluation tool to assess the effectiveness of a horticultural therapy. Delphi method was applied to classify the realms of evaluation and specify their components and constituting items. Delphi process was performed through three rounds and 24 professionals attended all the rounds as panel members. Some of the items were revised or removed according to the results of such tests as content validity ratio, agreement rate, convergency and stability of each item. On the contrary, a few new items were added by accepting the opinions of the professional panels. Previous to the Delphi, the realms of evaluation were classified into physical, cognitional, psycho-emotional and social ones on the basis of literature review, professionals' consultation and in-depth interview with practitioners. At the first round, 112 items constituting four realms were reviewed. The numbers of items to be reviewed were reduced to 107 at the second round and to 102 at the third round. As a result, 98 items in 4 realms were decided as proper evaluation points of horticultural therapy. The compositions of the four respective realms are as follows: 5 components and 27 items in physical realm; 4 components and 25 items in cognitional realm; 2 components and 24 items in psycho-emotional realm; and 4 components and 22 items in social realm. These realms, components and specific items derived from this study constitute indices to evaluate the effectiveness of horticultural therapy. In addition, they might be utilized as good guidelines for planning horticultural therapy programs.
