The purpose of this study was to examine how the vocational high school teachers perceive the direction of the ideal high school vocational education when suggesting mutual contrast positions on the desirable direction of high school vocational education. 1253 teachers from 25 specialization high schools nationwide participated in the survey. Through the review of previous research, we confirmed the axis of new vocationalism, vocationalism, and humanism on the purpose of vocational education. As a result of investigating the perception of vocational high school teachers about the purpose of vocational education, they tended to recognize the purpose of high vocational education toward vocationalism. In other words, rather than acquiring transferable skills, it is important to acquire concrete skills in specific areas, and it is more important to acquire specific skills that can be utilized immediately after graduation rather than coping with the changing job world. Teachers also recognized that it is more important to organize the contents of education according to the needs of industries and companies than to construct education contents for student 's holistic development. There was also a tendency for teachers to recognize that it is important to prepare them for work immediately after graduation rather than preparing them for as wide a career choice as possible. There was a tendency for the male teacher to perceive the purpose of vocational education more pro vocationalism than the female teacher. In addition, professional subject teachers recognized more pro vocationalism than general subject teachers. As a result of the regression analysis, it was found that gender and subject(professional subject vs. general subject) were significant variables related to vocationalism. And suggested that a careful approach is needed in the policy decision making process when considering the limitations of overly vocationally oriented education and the risks of frequent changes in the purpose and direction of high school vocational education.

This study examined the physicochemical water quality and evaluated the ecological health in 14 sites of Geum River (upstream, mid-stream, and downstream) using the fish community distribution and guilds and eight multi-variable matrices of FAI (Fish Assessment Index) during June 2008-May 2009. The analysis of the water quality variables showed no significant variation in the upstream and mid-stream but a sharp variation due to the accumulation of organic matter from the point where the treated water of Gap and Miho streams flew. The analysis of physicochemical water properties showed that BOD, COD, TN, TP, Cond, and Chl-a tended to increase while DO decreased to cause eutrophication and algae development from the downstream where Miho and Gap stream merged. The analysis of fish community showed that the species richness index and species diversity index increased in the mid-stream area but decreased in the downstream area, indicating the stable ecosystem in the upper stream and the relatively unstable ecosystem in the downstream. The analysis of the species distribution showed that the dominant species were Zacco platypus that accounted for 20.9% of all fish species and Zacco koreanus that accounted for 13.1%. The analysis of the fish tolerance and feeding guild characteristics showed that the sensitive species, the insectivore species, and the aquatic species were dominant in the mid-stream point. On the other hand, contaminants from the sewage water treatment plant of Miho stream had a profound effect in the downstream to show the dominance of tolerant species, omnivorous species, and lentic species. Therefore, it is necessary to improve water quality by reducing the load of urban pollutants and to pay attention to the conservation and restoration of aquatic ecosystems.

The Administration of Labor was responsible for the technical and practical functions like policy-making of labor matters and implementing the relevant laws. However, there has been a few record transferred to the National Archives to help find out the labor policy-making process. This is one of the typical examples that shows the discontinuity and unbalance, and disorderly filing of the administrative records in Korea. Naturally it is almost impossible to retrieve the appropriate content through the records file-name. Users should be at the trouble to compare the record items and their content one by one. For the re-organization of the Administration of Labor' records, this research suggests the four-level analysis of functions of the Administration. The Administration of Labor' survived records could be linked to each level function. And the publication of the 'Records Abstract Catalog' providing users with more information about the records would pave the way for easier access to the records. In addition, it also suggests the logical re-filing of the survived records of which we cannot find the order or sequence. This re-organization of the survived records would help to establish the acquisition and appraisal policy of the labor records as well as the new way of description and finding tool hereafter. Drawing up labor history map is a starting point for the acquisition strategy of the labor records, which could allow users to gain systematic access on the survived records. Of course, extensive investigation and research on the survived records is a prerequisite for the map. It would be required to research on the survived records of the other government agencies, including economic-social area ministries and investigation agencies and the National Assembly as well. It is also needed to arrange and typify the significant incidents and activities on thematic and periodic frames in the labor history. If possible to understand or connect the survived records and these accomplishments comprehensively, it would be of great help for the acquisition of the labor records and the related oral records projects.

The purpose of this study is to propose the rational mountain stream management strategy considering the natural conditions and social needs of the Republic of Korea. We reviewed domestic and overseas studies related to mountain streams, identified the study areas by text mining and co-word analysis using the VOSviewer program, and then analyzed the spatial and temporal study trends and topics of each study area. The results showed that domestic studies on mountain streams are still in an initial stage compared to overseas studies. Overseas studies on mountain streams can be classified into four groups: (i) habitat and species composition of fish and invertebrates, (ii) hydrological phenomena and nutrient migration, (iii) transport of sediment and organic materials and the relevant morphological changes by runoff flows, and (iv) plant species composition in mountain streams. Of these study subjects, domestic studies belonging to the (i) group mainly focused on macroinvertebrates while domestic studies belonging to the (iii) group regarded transport of sediment and organic materials as not the ecological disturbance but the source of sediment-related disasters. We then analyzed the rate of each research group to all papers by period and country. The results showed that the overseas studies belonging to (iii) and (iv) groups have increased with time, and the increase was mostly due to the studies in the United States, Brazil, Canada, and China. On the other hand, domestic studies belonging to (i) and (iii) groups increased somewhat with time, but there was a slight lack of correlation between the two subjects. Therefore, the hybridity studies to complement the shortage is necessary for the future.

Off-Site Construction (OSC) is a new construction method based on factory production. OSC (Off-Site Construction) is a new construction method based on factory production. Researches such as OSC-related design and production standardization, transport methods are actively conducted in the U.S., UK and other parts of the world as this new method has an edge over existing methods in terms of productivity, economy and quality. As the emergence of this new area requires reasonable management, an analysis of the scope of construction project management is required accordingly. Therefore, this research analyzed the study trends and relationships at the CM/PM range's "Operation level" to identify areas of study, relationship between studies and deficiencies in current research. This study carried out a comprehensive literature review of the OSC (CM/PM) research by analyzing 94 papers in Operation level as of September 3, 2018, and the analysis results are as follows. (1) Working stage level researches have been increasing rapidly since 2006. (2) Non-volumetric type is contributing most significantly at work stage level. In the building sector, it has been identified that problems such as residential: living, quality issues, non-residential: economic difficulties, factory: productivity problems have been addressed. (4) The Non-volumetric pre-assembly type dealt with the economic feasibility of residential and non-residential buildings, whereas the modular type was studied in regards to assembly quality. (5) From 2006, project management areas (e.g., quality, human resources, risks) have been expanded. It is expected that this research will help find new areas of research for OSC. If the analysis is carried out to the level of the industrial, corporate and project phases in the future, it is deemed that the overall research flow and area of the OSC industry can be identified.

This study was conducted to investigate 106 grassland farms in six provinces including Chungcheongbuk-do, Gangwon-do, Gyeonggi-do, Gyeongsangbuk-do, Gyeongsangnam-do, Jeju-do, and Jeollanam-do to present their problems and causes by surveying the actual state of grassland farms during three years(2014~2016). The grassland survey was divided into three categories; used as the perennial grasses and annual forage crops (Complied with Grassland Act), not used as the perennial grasses and annual forage crops (Not complied with Grassland Act) and failed to meet the farmer and some items are missing or inaccurate (Insufficient contents). Among the surveyed grassland farm, 68 farms (64.2 %) were complied with Grassland Act but 30 farms (28.3 %) were not complied with Grassland Act. Especially, the 8 farms (26.7 %) not complied with Grassland Act used the grassland as other purposes such as tree growing, golf club and swine farm etc.. Therefore, strict on-site investigation by local governments is required to prevent the grassland from being used by illegal purposes. And there's a strong likelihood that 5 farms (62.5 %) avoided the survey violate the positive law. Grassland grades used by the local administrative agencies were not influenced by the factors affecting the yield (existence and non-existence of overseeding and fertilization by grassland grade, soil pH and organic matter content). This results suggest that there is a fundamental problem on the current grassland grade system based on the yield and the irregular time of investigation and lack of on-site investigation are another causes for inaccurate grassland grade. Therefore, the new method evaluating grassland grades which is not based on yield and the thorough on-site investigation by local administrative agencies are necessary when the grassland grade is evaluated.

Purpose: The purpose of this study was to explore about 2-year-old infants' attachment security to a child care teacher and peer play process through a case study. For this purpose, the attachment security was assessed with attachment Q-set to 2-year-old five infants at a day care center in Seoul. Participants of this study are four infants included two infants attached securely to their child care teacher and two infants attached insecurely to their child care teacher. Methods: Participant observation was conducted from April 12 to July 19 in 2018 through 36 observations in free play activities. The Data collected from the transcriptions of video shoots and teachers' interviews, child care plans, and reflexive journal was analyzed and interpreted. Results: The main results of the research were as follows: The beginning of peer play, when infants invited their peers to play, secure attachment infants selected suitable play partners and asked for a specific play behaviors. However, insecure attachment infants invited unsuitable play partners and asked uncertainly play actions to peers. In addition, when infants entered in-progress play, secure attachment infants understood the context of play but insecure attachment infants did not understand the context of play. In the progress of peer play, secure attachment infants cooperated with peers, shared play objects, but insecure attachment infants did not cooperate complementally with peers and express only their opinions. As well, insecure attachment infants could not play harmoniously without child care teacher's interventions. In the end of the peer play, secure attachment infants finished in collaboration with peers but insecure attachment infants failed to finish with the peers and was turned into play with the child care teacher because of peer conflict. Conclusion/Implications: This study has implications for basic resources to think about the role of child care teachers by helping them understand about the relation 2-year-old infants' attachment security to them and peer play process.

This study aimed at examining the suitability of $Tenax^{(R)}$ for the migration testing of food packaging materials, which is currently approved in the EU as a dry food simulant. The results are used as a basis to examine the feasibility of introducing $Tenax^{(R)}$ to Korean regulation. The OMVs of test specimen into various solvents (diethyl ether, ethanol, pentane, and acetone) after exposure to $100^{\circ}C$ for 1 hr were compared. Diethyl ether showed the highest OMV ($1.33mg/dm^2$) among the solvents tested. When the tests were conducted with different amounts of $Tenax^{(R)}$ of 2, 4, or 8 g per specimen, the OMVs were 0.75, 1.33 and $1.40mg/dm^2$, respectively. The OMV obtained with a closed system after wrapping with aluminum foil showed a significantly higher OMV ($1.61mg/dm^2$) than that without aluminum wrapping ($1.318mg/dm^2w$) and an open system without lid ($1.06mg/dm^2$). The specific migration rates of surrogates spiked in the polyethylene test film and paper samples into $Tenax^{(R)}$ were compared with those into liquid food simulants including 95% ethanol and n-heptane, and actual foods such as starch, skim milk, and sugar. In general, the specific migration levels of surrogates into $Tenax^{(R)}$ were similar compared with n-heptane, however those were significantly higher than into actual foods. These results suggest that $Tenax^{(R)}$ may be used as a food simulant for the long-term preservation of dried foods and paper products. However, more studies need to be conducted to investigate the factors influencing the migration into $Tenax^{(R)}$, such as the types of foods and packaging materials tested, migration conditions, and surrogates properties etc.

This study examines differences in perception between applicants and admissions committee members regarding evaluation criteria for admission to career and technical high schools in Seoul. This investigation, based on "The survey on policy for career and technical high school admissions," seeks to explore and consider the various criteria for selecting and evaluating students. The target populations of the survey were the educators in charge of admission and freshmen in Seoul career and technical high schools. We report three major findings, with the first pertaining to the existing criteria and policies for admission to career and technical high schools. While educators agreed with the intent and reasoning behind the school's competitive spots, they were overall dissatisfied with the selection method and the lack of a requirement for academic transcripts. Matriculated students, in comparison, expressed greater satisfaction with the existing criteria for admission. Secondly, when assessing the importance of various evaluation components in an application, educators viewed the interview and attendance record as the most valuable components of the application, followed by future plans, personal statement, volunteer work, and portfolio, in order of decreasing importance. Students ranked attendance record, interview, personal statement, portfolio, future plans, and volunteer work as most to least important components of their application. Thus, students regarded the personal statement and portfolios as being of higher priority than did the educators. The last major finding pertained to students' rationale for applying and educators' selection criteria. At the time of application, students focused on aptitude and job prospects after graduation, while educators valued personality and competence. In summary, the applicants' viewpoints and actions aligned much more closely with the mission of the Seoul Metropolitan Office of Education than did those of the educators in charge of admission. Thus, in order to establish a consensus between the policy and mission of career and technical high schools, each career and technical high school should clarify the exact criteria for their ideal candidate. There is also a need to bridge the gap in perception between the applicants and educators regarding selection strategy, to establish a harmonized evaluation criteria. These goals are necessary to attract and recruit talented, bright individuals who will meet the demands of today's society.

Consumers demand that corporates fulfill their social responsibility by exerting influence over not only economical values but also social values in markets. Given such a social mood, most corporates are actively engaging in Corporate Social Responsibility(CSR) activities, and marketing scholars continue to study the effects of such CSR activities. Numerous such studies examined the relationship between CSR activity and brand equity. Moreover, virtually, a majority of these studies focused on consumer responses to CSR activity from an individual brand perspective. In a situation in which brand management must consider the spillover effects of brands, firms holding various brands should consider these spillover effects when they establish CSR activity strategies. Therefore, we examine the effects of CSR activity using a comprehensive approach that considers the hierarchy of brands. Additionally, we develop a new perspective on fit that has been used as a major influence on the effects of CSR activity. We argue that the mixed results of the impact of fit regarding the effect of CSR activities is attributed to the influence of connections among brands based on the hierarchy of brands. We then examine the effect of two types of CSR activity strategies that reflect the relativity of fit. The results reveal that there was no difference in impact of the two strategies based on unique roles and traits of corporate brand and effects of low fit. Also, we found that the corporate brand focused strategy creates a greater change in consumers' attitudes than does an individual brand focused strategy in the case of a particular brand. This finding is meaningful because it indicates that a hierarchy of brands may relatively reduce the impact of the role of fit, unlike general arguments from previous related research. Second, the spillover effects from the CSR activities of individual sub-brands belonging to the same corporate brand were confirmed. Therefore, we clearly verified the role of the hierarchy of brands. Although both strategies cause changes in consumer attitude toward brands engaged in CSR activity, overall, a corporate brand focused strategy turned out to be more effective than an individual brand focused strategy because of the spillover effects of brands. Third, this study verified the effect of a corporate brand focused strategy through a moderating effect analysis of the degree of association between individual brands and corporate brand. Given these results, we identified a moderating role in the degree of association and the changes in consumer attitudes toward both main brands engaged in CSR activities and other different individual brands, which were caused by the spillover effects of brands. Finally, this study addresses implications and limitations.
