The purpose of this study was to understand how participants' experiences of participating in self-sufficiency projects were. To do this, we analyzed phenomenological methods using in-depth interview data of 48 participants from the Central Self-Sufficiency Foundation, which is qualitative data of the "Project for Strengthening Self-Support for the Working Poor". The study revealed 214 meaningful statements and general re-statements, 24 themes, 9 themes cluster, and 5 categories. Participants' experience was found to be forced work, felt alienated from the self-sufficiency business, and could not receive a clear vision for the future. At the same time, the experience of participating is an opportunity for motivation for change in one's own life, and the essence of becoming a stepping stone to move forward for self-reliance has been derived. Based on the results of this study, we proposed a practical policy task to create a positive expectation effect.

Recently, due to global warming, the average temperature of the earth has risen, and the glaciers in the Antarctic and Arctic melt, leading to a rise in sea level, which is accompanied by powerful natural disasters such as strong typhoons and tsunamis around the world. Accordingly, a precipitation in summer in Korea also increased, and changes in the form of precipitation were showed with the increase. Compared to the past, the frequency of localized heavy rain is increasing, and the damage from flooding and flooding is increasing day by day. In this study, based on the precipitation data measured in hours from May to September from 2016 to 2021 according to the change in the precipitation form, according to the nature of the torrential rain investigated the change in the summer precipitation form. In addition, the trend of localized heavy rain from 2016 to 2021 was confirmed by classifying them into two types: localized heavy rains caused by cyclones and weather front, and by typhoons and large-scale cyclones. Through this, the change in precipitation due to the climate crisis should not be viewed as a single phenomenon, it should be reflected and discussed on our life focused on scientific and technological development, and it should be used as a stepping stone for realizing a humanistic.

The Soswaewon Garden, which was constructed by Yang San-Bo around 1520, is a private traditional garden in Korea. Soswaewon Garden has long been and still is the focus of continuous research. However, relatively few studies have been conducted on the restoration of buildings that were lost in the past. The Goam-Jeongsa and Boohwondang buildings, which were lost in 1597 during the Japanese invasion, were restored in 1614 and depicted in a picture of Soswaewon Garden in 1755. However, they eventually disappeared and no longer exist in the present. Therefore, the restoration of these two buildings is considered an urgent task. This research aims to search for the original location of these buildings and estimate their size and shape in terms of physical space. Several years ago, an estimation of the building site was carried out, providing a stepping stone on this matter. This can be studied through "Soswaewon's 48 quatrains with five Chinese characters in each line," "Soswaewon-sasil," and "Soswaewon's drawing." Some parts of the shape of Soswaewon also appear in the "Yuseoseokrok," which is helpful. Thus, in this research, information on the Goam-Jeongsa and Boowondang buildings appearing in research results and literature to date are collectively analyzed. The location and architectural features of both buildings are identified by focusing on excavations. Also, for the purpose of restoration planning, base data on the location, size, and shape of both buildings are presented. In line with this process, a valid restoration plan is presented by analyzing the abovementioned historical research materials and comparing empirical data, such as excavation results.

Smart Grids are intelligent next generating Electric Power System (EPS) that provide environment-friendliness, high-efficiency, and high-trustworthiness by integrating information and communication technology with electric power technology. Smart grids help to supply power more efficiently and safely than past systems by bilaterally exchanging information between the user and power producer. In addition, it alleviates environmental problems by using renewable energy resources. However, smart grids have many cyber security risks because of the bilateral service, the increase of small and medium-sized energy resources, and the installation of multi-sensors or control devices. These cyber risks can cause critical problems within a national grid through even small errors. Therefore, in order to reduce these risks, it is necessary to establish a cyber security strategy and apply it from the developmental stage to the implementation stage. This thesis analyzes and recommends security strategy in order to resolve the security risks. By applying cyber security strategy to a smart grid, it will provide a stepping-stone to creating a safe and dependable smart grid.

Two dominant phenomena in modern world; population ageing and digitalization, have led public sector organizations to heavily rely on B2C(Business-to-Consumer) mobile applications. Yet, fatal concerns and complaints have often been raised by the mobile application users, notably from social welfare sector. With the continual expansion of digital landscape as well as the growth of life expectancy, usage of mobile applications has become prevalent across the stakeholders involved in social welfare sector. 'Smart Long-Term Care (SLTC)', inter alia, is a primary example of such mobile applications, designed to support Long-Term Residential Care (LTRC) service. The main goal of SLTC is to serve more convenient and practical LTRC service for both caregivers and care receivers. To examine user satisfaction of SLTC mobile application, this study investigates existing challenges and means to improve user satisfaction. Hence, we conducted this study using two methods: in-depth interview and topic modeling. Interestingly, two research outcomes commonly indicated that 5 factors (stability, accessibility, usefulness, responsiveness, and ease of use) were found significant in affecting user satisfaction of SLTC. Our findings suggest that the aforementioned factors can be seen as potential causes of the genuinely low user satisfaction. Eventually, this work will be a stepping-stone to elevate the overall quality level of LTRC service along with the user satisfaction degree of SLTC mobile application.

Mokpo is a port city in the southwest of the Korean Peninsula. The popular song "Tears of Mokpo" is a song planted in the hearts of the entire nation. In this content, there are Yudalsan Mountain and Samhakdo Island in Mokpo, and people vaguely know this area, but it is a familiar place. In particular, Samhakdo Island is a representative brand that symbolizes Mokpo and is a place with regional identity. Mokpo City is creating many facilities infrastructure to develop Samhakdo Island. It is a stepping stone for converting the local economy into a tourism industry. However, the development of performance contents for the soft power of local culture is weak. In this respect, this study presented performance contents for Samhakdo Island, Mokpo's representative brand, for local tourism attractiveness. The research progress is a study on planning and researching performance contents using the location of Samhakdo Island in Mokpo. First, the background of the theory of performance content planning based on local placeability was examined. Next, Samhakdo Island in Mokpo proposed planning for performance contents.

Objectives: An appropriate level of cost support is being proposed to maximize the participation rate. In addition, as the amount of support is highly concentrated at the level of the limit under the current level of supports, the level of cost support is low when the actual level of cost of measuring the working environment exceeds the limit. This paper describes the adjustment of an appropriate cost support rate. Methods: First, this paper analyzes the current cost support status using data from the KOSHA. Second, an alternative for adjusting the cost support rate is presented in consideration of the incentive aspect. Third, we present simulation results for the average cost support rate, the impact of each alternative on finance, and more. Fourth, the most desirable adjustment method is presented after comparing and analyzing the results of various alternatives. Results: In this paper, we present a new scale model. This model is a mixture of flat-rate, fixed rate, and subside cap. It is expected that the new model will not only facilitate participation in businesses with low measurement costs, but also have the effect of controlling measurement costs for institutions that incur greater costs. It is also expected that setting a cap will have the effect of considering government finances and inducing excessively costly institutions to reduce costs. Thus, the new model is likely to be superior to others. If the fourth plan is applied to new businesses and the fifth plan is applied to sustainable businesses, the average cost support rates will be 87.68 percent and 65.18 percent, respectively, and the needed finances will be 2.5 billion won, 18.8 billion won, and 21.3 billion won in total. Conclusions: It seems most desirable to introduce a new model that combines flat-rate, fixed-rate, and subsidy cap systems and achieve an appropriate cost support rate through this model.

The importance of interoperability between weapon systems is continuously increasing. Usually it is implemented by data exchange. The existence of information heterogeneities between systems decreases the efficiency and quality of the implementations enterprise-widely. Many other developed countries increase the efficiency and quality of the implementations by using information exchange model commonly. However, Korean military is still not aware of the importance and necessity of the model. This study explains the necessity of development and adaptation of the Korea command and control information exchange model(KC2IEM), and presents the methodology for the development of the model, and verifies and improves it through a prototype model development. The completion of the information exchange model could not be possible by academic research, therefore this study contributes as a motivation and a stepping stone for the following developments.

Open Data is an essential resource for the data industry. 'Act On Promotion Of The Provision And Use Of Public Data', enacted on July 30, 2013, mandates public institutions to manage the quality of Open Data and provide it to the public. Via such a legislation, the legal basis for the public to Open Data is prepared. Furthermore, public institutions are prohibited from developing and providing open data services that are duplicated or similar to those of the private sector, and private start-ups using open data are supported. However, as the demand for Open Data gradually increases, the cases of refusal to provide or interruption of Open Data held by public institutions are also increasing. Accordingly, the 'Open Data Mediation Committee' is established and operated so that the right to use data can be rescued through a simple dispute mediation procedure rather than complicated administrative litigation. The main issues dealt with in dispute settlement so far are usually the rights of third parties, such as open data including personal information, private information such as trade secrets, and copyrights. Plus, non-open data cannot be provided without the consent of the information subject. Rather than processing non-open data into open data through de-identification processing, positive results can be expected if consent is provided through active rights processing of the personal information subject. Not only can the Public Mydata Service be used by the information subject, but Open Data applicants will also be able to secure higher quality Open Data, which will have a positive impact on fostering the private data industry. This study derives a plan to establish a rights processing platform to enhance the usability of Open Data, including private information such as personal information, trade secrets, and copyright, which have become an issue when providing Open Data since 2014. With that, the proposals in this study are expected to serve as a stepping stone to revitalize private start-ups through the use of wide Open Data and improve public convenience through Public MyData services of information subjects.

Objectives This study was conducted to observe physiological changes when the function of spleen was extremely deteriorated, and to make an animal model with spleen deficiency. Methods The Normal group (Nr group) was not administered with Senna Folium extract. The SFE group(Senna Folium extract group) was administered with Senna Folium extract every day for the first 2 weeks and then every other day for another week. And the SFE_G group(Senna Folium extract_Ginseng group) was also administered with Senna Folium for 3weeks like the SFE group and fed with ginseng in the third week. Results The score of spleen deficiency was significantly higher in SFE group than in the Nr group and significantly lower in the SFE_G group than in the SFE group. The total weight gain was significantly lower in the SFE group than in the Nr group, and the average daily weight gain was significantly lower in the SFE group than in the Nr group. The difference in stool weight before and after the process of drying was significantly higher in the SFE group than in the Nr group, and significantly lower in the SFE-G group than the SFE group. There was no significant difference in the outcomes related to cold and heat among the three groups. Conclusions Through this study, the animal model with spleen deficiency was developed to prepare a stepping stone for animal tests to verify the efficacy and safety of constitutional prescriptions.
