This study aimed at understanding the experience in deciding for childcare of unmarried lone mother and searching for intervention methods through in-depth examination of the essence of the experience. To achieve this, the Colazzi analysis of phenomenological research was applied. The subjects of study were 7 unmarried lone mothers in early age of the twenties and thirties, who resided in an institution for unmarried lone mothers. An in-depth interview was held individually with them with question of "What is the experience in deciding for childcare as a unmarried lone mother" twice on the average from Nov. 2003 to Feb. 2005. The results found that a unmarried lone mothers' experience in childcare meant 'resurrection' through analyzing 22 themes and 7 theme clusters(confusion due to pregnancy, harsh feeling for reality suffering alone, feeling of love for a baby, mental conflict about childcare, decision toward childcare, firm in decision, hope for resurrection). Although the results of this study have the limitation of generalization due to phenomenological study, it will contribute to accepting and understanding mother-and-child families as one type of family rather than regarding them as being difficult or alienated in family and society, to recognizing the need of taking back their rights, and to suggesting intervention methods for unmarried lone mothers.

This study was carried out to evaluate the rheology of flour doughs containing 0.5% of hydroxypropylmethyl-cellulose (HPMC), methylcellulose (MC), and sodium alginate (SA), respectively. Farinograms, alveograms, a rapid visco analyzer (RVA), and rheofermentometer were employed in the analysis. According to the farinogram tests, the hydrocolloid additions caused changes in water absorption, dough development time, stability, and breakdown. The dough containing HPMC had the highest water absorption at $67.4{\pm}0.12%$. The HPMC dough also had the longest development time ($8.2{\pm}1.04$ min), stability ($12.7{\pm}0.42$ min), and breakdown ($7.9{\pm}1.3$ min). From the alveogram tests, P, G, and PIL values increased, whereas the L value decreased. The W values of the HPMC and SA doughs were increased, but that of the MC dough was decreased. According to the RVA results, the HPMC and SA doughs had reduced initial pasting temperatures whereas that of the MC dough was increased, but the difference was not significant. The peak viscosity of the MC dough also increased. Furthermore, all the doughs had increased breakdown times and decreases in final viscosity and setback. In the rheofermentometer tests, the HPMC dough presented the highest $H_m$, and the SA dough had the largest total volume.

The purpose of this study was to understand the labor division between men's housework and market work and to research the change of men's contribution to housework. And it was also examined what kinds of valuables work on a change in men's market work and housework. The information about men's change in the labor division was collected from the biggest 5 news papers in Korea for last five years for this study. And either men's new participation trend to household work did. Words searched for this study were men, labor, family, home, housewife, work, household work, father etc. Korean men have experienced a overloaded breadwinner role and have worked most in the world since 1960s. But Korean men's working time was continuously decreased a little every year. As Korean Companies had fired many worker during IMP economic crisis period, Korean men had to work more than before because of decreased fellows and they should have concentrated on their work at the sacrifice of private life and family-sharing time. On the other hand, some men were started to participate to do housework as a results of long-unemployment and early retirement after this periods. 5 day working system be in forced gradually since 2003 especially make men come back home and interest on housework. So Korean men's housework participation is gradually increasing by the practical application of sex-equitable politics such as 5 day working system and men's suspension regime for baby care. father's increased participation to children education and care, men's new family-oriented life style, dual-sexuality education system, and socially changed perception to husband housemaker. These interrelated trends demands us to shape a new labor division pattern in the family that make change the breadwinner/homemaker conception by the gender role. Now, all of family, men, women, and children have to join housework. It would help women, men, and all families make more human and equitable relationship.

Under the Korea Building Act, anyone planning to build a building or buildings on a site over $200m^2$ must plant plants over a specific area. In large scale development this rule is adhered to well, but such is not the case in small scale development. Therefore, special attention must be given to small scale development. Thus, the purpose of this research is to analyze the current situation and practice of planting at small scale development sites in Seoul, and then suggest policies for improving them. In this study using the data covering Seongbuk-Gu and Gangnam-Gu, which was surveyed in 2002, the current situation and practice of planting at small scale development sites was analyzed. After a questionnaire survey was conducted with government officers and building owners, the same analysis was made. Then the policies for improvement were extracted. The results are as follows: 1. In superordinate planning stage, because the minimum standards are too low, those must be strengthened. Any district plan does not control planting in private building lots. This requests active application of planting in private building lots as a design control measure in district planning. 2. In the building design stage, there are no guidelines. The obligation of building set-back between adjacent buildings by the Korean Building Act produces mass shaded and inferior planting beds. The act also is blocking landscape architects' participation in small scale development. And wall installations deteriorate the streetscape and growth of plants with shading. Therefore guidelines must be made. 3. In each stage of the building permit, the permit for building completion, and maintenance the Korean Building Act is blocking landscape architects' participation in small scale development, so the planting plan is completely handled by nonprofessional persons. Therefore, the act should be amended in order to make way for landscape architects' participation in each stage of the small scale development process.

This study provides quantitative constraints on Neogene uplift in the Korean peninsula using onshore paleo-shoreline records and seismic data. The eastern margin of Northeast Asia including Korea sits in the back-arc system behind the Western Pacific Subduction Zone, a complex trench triple junction of the Philippine Sea, Pacific, and Eurasian (Amurian) plates. An analysis of seismic data in the subduction zone shows that the pattern of uplift in the peninsula mirrors the extent of deep seismicity in subducting Pacific plate beneath. Combined with previous tomographic studies it is proposed that uplift is partly driven by asthenospheric upwelling caused by a sinking slab during the Neogene. In addition, the SHmax orientations of E-W and N-S trends in the peninsula are consistent with the prevailing in-situ stress fields in the eastern Eurasian continent generated by various plate boundary forces. The uplift in Korea during the Late Neogene is attributed, in part, to lithospheric failure relating to faulting movements, thus providing a link between dynamic effects of mantle upwelling at sinking slab edge and lithospheric responses driven by plate boundary forces.

Sambok (三伏, Three Hottest Days) is the common designation of Chobok (初伏, Early Hot Day), Jungbok (中伏, Middle Hot Day), and Malbok (末伏, Late Hot Day), and widely known to be one of the Korean folk customs. Hence, Sambok is notated in Manseryeok (Ten Thousand-Year Almanac) and in the annual astronomical almanac published by Korea Astronomy and Space Science Institute. In this paper, we investigate the changes of Sambok in Korea based on various documents such as Joseonwangjosilok (朝鮮王朝實錄, Annals of the Joseon Dynasty), Jeungbo-Jakryeoksik (增補作曆式, The Supplement of Manual for Calendar Making), astronomical almanacs, and so forth. According to Jeungbo-Jakryeoksik preserved in Kyujanggak Institute for Korean Studies, Chobok and Jungbok are defined as the third and fourth Gyeongil (庚日, The Day Starting with the Seventh Heavenly Stems in Sexagenary Cycles Assigned to Each Day) after the summer solstice, respectively, and Malbok is the first Gyeongil after Ipchu (Enthronement of Autumn). However, if the summer solstice is Gyeongil, then the third Gyeongil counting from the solstice becomes Chobok. Malbok depends on the time of Ipchu. Ipchu itself becomes Malbok if the time of Ipchu is in the morning, or next Gyeongil becomes Malbok if it is the afternoon. On the other hand, Malbok is defined as Ipchu itself regardless of its time according to Chiljeongbobeob (七政步法, Calculating Method for Sun, Moon, and Five Planets), Chubocheobryeo (推步捷例, Quick Examples for Calendrical Calculations), and so on. To verify the methods used to determine Sambok, we examined the record in the extant almanacs during the period of 1392 to 2100 for which the summer solstice or Ipchu is Gyeongil. As a result, we found a periodicity that if the time of Ipchu is in the morning, in general, the time is in the afternoon after two years and then is back into in the morning after nineteen years, i.e., the 2 + 19 years periodicity. However, we found the 2 + 17 years periodicity in some years. We also found that the Chobok method of Jeungbo-Jakryeoksik has been used since 1712, the thirty-eighth reign of King Sukjong (肅宗). In addition, we supposed that Malbok had been determined by the method like Chubocheobryeo since either 1846, the twelfth reign of King Heonjong (憲宗), or 1867, the fourth reign of King Gojong (高宗). At present, these methods of Sambok are customarily used without any legal basis. We, therefore, think that this study will help conventionalize the method defining Sambok in the future.

Recently, STEM education and improvement in creativity took a lot of attention in local and foreign educational programs, and the robot education is regarded as one of the answers which can achieve the objectives. The robot education is quite active locally in various ways including robot classes for after school program in elementary schools, a number of robot competitions, and education for the gifted. Under these circumstances, the qualification test for robot technology is developed to provide a standard for evaluating professional knowledge on robotics and is currently under consideration to be one of the government-approved qualification tests. However, compared to the robot classes for after school program, this test is not well recognized by most teachers in elementary and middle schools. This paper addresses and analyzes the current status of the test, in particular, backgrounds, qualification standards, organizing committee, intention of presenting questions, examples of problems used in the test, and demands raised by applicants, etc. Base on the analysis, some suggestions are made to establish a solid standard for evaluating robot technologies. It is suggested that the level of difficulty and contents covered should be properly adjusted considering the level of applicants. In addition, it is essential to provide well organized supplementary material for students and wide range of contents on robot technology. Finally, some efforts including cooperating with the robot classes for after school program should be made to invigorate the test.

In the modern era, the elementary schools in the Republic of Korea are advanced with the competitive world. Thus advancement in technology, and other factors in the elementary schools are releases some kind of particulate matter (PM), which causes deleterious effects on school students health, academic program, growth and development. The school students are susceptible to PM particularly, PM₁₀ and PM_2.5. Based on this hazardous effect of PM on school students we conducted the research on the elementary schools class rooms by introducing vertical gardening system to get the schools "ever green". The main aim of this study is to investigate the environmental factors in the educational effect program in the class rooms and indoor air quality changes. For the educational effect, the 4th operation program was applied to 2 schools for 2 hours once a month from September to December 2019. Each school conducted a survey on satisfaction, plant friendliness, and environmental sensibilities, targeting classes that participated in the green school program and those who did not. The environmental effects were monitored by installing indoor air quality facility in the program participating classes and the non-participating classes. From November 2019 to December 2019, three factors were measured: PM10, PM2.5, and humidity. The results were analyzed by T-test using the SPSS 24.0 software program. As a result of the analysis, student's overall satisfaction with the program and their intention to re-engage were high in terms of educational effect. It was also found to be effective in emotional, educational, social, and physical aspects. In particular, it was found that there was a statistically significant effect on improving plant friendliness in terms of plant friendliness and environmental sensitivity. In terms of environmental effects, it was found that there was a significant difference between the program-applied and non-programmed classes in PM10, PM2.5, and humidity. Through this study, it was confirmed that the plant education program using vertical gardens is effective in both the educational effect and the improvement of indoor air quality in the classroom. In conclusion, vertical gardening system in the elementary schools should implement for the beneficial of young generation development and back bone to the nation.

Korean society is a mix of western and traditional cultures. Even though the patients try to recover through both aspects, hospital only utilizes a western approachs. When they have suffered from a chronic disease, especially diabeties meliitus(DM), application of folk medicine is more varied but the nurses are unaware of the practices. This study was done to describe the current use of the folk medicine with which the patients with DM have had an experience and to identify the relationships between the westernized medical care and folk medicine application. The 244 patients with non-insulin dependent diabetes millitus who participated were interviewed at a DM education clinic in a 1500-bed hospital. The results of the study are as follows: 1. 54.1%(N=133) of the participated patients in this study have had a folk medicine. 2. 44 kinds of folk medicine were used for the treatment of DM. Among them 14 items were used by more than two people and the rest were used by one person. Among the used items, 70.4% consisted of various types of plants, 11.4% was animal material and 18. 2% was the mixed group. As a single item, Commelina Communis(Dalgaebi) was the most frequently used(62.8%), followed by the root of Rosa rugosa(Haedangwha) 14.3%, and Youngi mushroom 13.6%. 3. In the analysis of the relationships between the general characters of the patients with regular fol1ow-up(F-U), self blood sugar test(BST) and folk medicine usage: 1) The higher the educational back ground patient had, the lower the folk medicine usage was ($X^2$=14.265, P=.003). 2) The more complex their treatment was($X^2$=24. 016. P=.000). and the longer they had suffered from DM($X^2$=75.739, P=.000), the fewer they visited regular F-U. On the other hand, they did self-BST well($X^2$=7.722, P=.021 : $X^2$=14. 775, P=.002) and had more folk medicine($X^2$=33.382, P=.000 ; $X^2$=43.410, P=.000). 3) If they had suffered many symptoms, they had fewer regular F-U ($X^2$=13.192. P=.001). On the other hand, they had more folk medicine($X^2$=6.070, P=.048). 4) The group of family history($X^2$=6.801. P=.009) and the group of DM education experience($X^2$=15.678, P=.000) carried out self BST well. DM education group used more folk medicine($X^2$=8.680, P=.003). In conclusion, DM education should be grouped according to the treatment type and suffering period. Then the management of DM would be effective and the vague application of folk medicine would be decreased.
