This study was conducted to examine the morphological characteristics of those Azalea Cultivars(hereinafter, Azalea Cultivars) that are mainly used for landscaping in Korea in order to prepare classification criteria. As testing materials, major Azalea Cultivars cultivated in large quantities by its producing companies were collected. Thereafter, the qualitative and quantitative characteristics of the traits of Azalea Cultivars were investigated in the way of characteristic investigation for new cultivars of azalea used by the Korea Seed and Variety Service in order to classify them and prepare the classification criteria. Since cultivar names have not been established for Azalea Cultivars for landscaping thus far, the data were compiled using the names used by cultivating companies. According to the results, Azalea Cultivars cultivated in Suncheon, Jeonnam mainly for landscaping were 10 in number; Beni, Daewang, Three, Zasanhong, Hancheol, Sancheoljuk, Gyeobsancheoljuk, Baekcheoljuk, Akado, and Seok-am. Among them, the cultivars Beni, Daewang, and Three could not be easily distinguished from each other because they are commonly called Yeongsanhong by cultivating companies and the shapes of their leaves and flowers are similar to each other. In particular, the flower color of Beni was 'bright red', that of Daewang was 'vivid purple', and that of Three was 'bright purple'. In addition, Zasanhong and Hancheol were similar to each other in shape the degree of expression of spots on the flowers and the gloss on the front side of the leaves of Hancheol were higher and stronger compared to that of Zasanhong. Sancheoljuk flowered in early April, earlier compared to other Azalea Cultivars. Gyeobsancheoljuk is an elementary species of Sancheoljuk and it had double flowers although all other traits were similar to those of Sancheoljuk. Although Baekcheoljuk was easily distinguished because it had white flowers, its leaves were similar to those of Akado the reason why these two cultivars could not be easily distinguished from each other. The cultivar Akado flowered early May later compared to other Azalea Cultivars and its flowers were relatively large in diameter as with Baekcheoljuk and Sancheoljuk. Finally, the cultivar Seok-am was easily distinguished because it had smaller leaves compared to other cultivars and it flowered late as with the cultivar Akado.

Darangnon in Gachon Village, Namhae-gun, Gyeongsangnam-do, is the first designated environment among Korea's industrial-based historical and cultural sites and is still the only one that involves agricultural activities. Although the stonework, which is the infrastructure environment here, has limitations that inevitably lead to natural and artificial deformation due to its nature, there has been no research to consider the situation so far. As of the end of May 2020, this study investigated and analyzed the damage in the sub-area of the survey, which is approximately 30% of the scope of the designation of the scenic spot, from a quantitative and qualitative perspective. As a result of the study, the state of loss, which reveals the physical damage of the arctic rice paddy stone retaining wall in the environment under investigation, was particularly serious around the coast, in the northern area with high slopes, and near tourist information centers and parking lots. On the other hand, the qualitative aspect of the damage to the stonework was noticeable in the repair of heterogeneous materials on the stone retaining wall adjacent to the village and parking lot, and the landscape damage caused by the cladding of plants was found in an environment far away from the residence. In addition, natural environmental factors such as slopes, elevations, and soil showed a close relationship with the degree of physical damage of the stone retaining wall, the higher the slope, the higher the elevation, and the better the soil drainage, the greater the impact. These results suggest that humanities environmental factors such as cultivation activities and management entities have important factors in the physical damage and management of stone retaining wall. Therefore, it is deemed essential to find management measures with local residents along with improving the agricultural environment, such as securing agricultural water and soil improvement, for the preservation of tuna paddies and stone retaining wall in the future.

Background: Breast cancer is the most common cancer in Iranian women and usually features delayed presentation and late diagnosis. Interpretation of symptoms, as the most important step, has a significant impact on patient delay in seeking treatment. There is a dearth of studies on symptom appraisal and the process leading to seeking help in breast cancer patients. This study explored the perceptions and experiences of Iranian women with self-detected possible breast cancer symptoms. Materials and Methods: A qualitative method was conducted involving in-depth semi-structured interviews with 27 Iranian women with self-discovered breast cancer symptoms. Participants were purposefully selected from women who attended Cancer Institute of Tehran University of Medical Sciences during June 2012 to August 2013. The audiotaped interviews were transcribed and analyzed using conventional content analysis with MAXQDA soft ware version 10. The trustworthiness of the study was verified by prolonged engagement, member validation of codes, and thick description. Results: The main concepts emerging from data analysis were categorized in four categories: symptom recognition, labeling of symptoms, interactive understanding, and confronting the fear of cancer. Symptom recognition through breast self-examination, symptom monitoring and employing prior knowledge distinguished normal from abnormal symptoms and accompanied with perception of being at risk of breast cancer led to symptom labeling. Social interaction by selective disclosure and receiving reassurance from a consultant led to confirmation or redefinition of the situation. Perceived seriousness of the situation and social meanings of breast cancer as a stigmatized and incurable illness associated with loss of femininity were reasons for patient worries and fear. Conclusions: This study emphasized that entangled cognitive, emotional and socio-cultural responses affecting understanding of symptom seriousness require further investigation. It is suggested that programs aimed at shortening patient delay in breast cancer should be focused on improving women's knowledge and self-awareness of breast cancer, in addition to correcting their social beliefs.

The subway is one of the representative urban public transportation systems. Since its being opened in 1974, the Seoul Subway has been continually extended, and new lines are being added in the metropolitan and outskirt areas, even at present. As a result, the numbers of transfer stations and transfer sections have been significantly increased, making the usage of the subway system more and more complicated. In the transfer stations with big floating population and overlapped flows of traffic in the subway, passengers want their movements to be more precise and faster, without taking the wrong trains by mistake. Therefore, the visual information system for the subway inside the stations is extremely important. At the same time, the visual information system is required to be easy to understand and use, even if the passengers do not have previous experience of using the subway. In this research we studied the problems existing in the visual information system which is currently working in the subway system, and suggest the direction of the improvement of the subway service based on our studies. This research was mainly performed at Sindorim Station, one of the busiest stations in Seoul Subway with huge floating population and complex transfer sections. The purpose of this research is the investigation of behavioral and recognitive characteristics of passengers in the transfer sections through preceding research and qualitative analysis, to draw the direction for future improvement of the current system and suggest the improved experience of using the subway system.

The purpose of this study was to analyze trends in conceptual change research in the field of Earth Science education conducted in Korea and to provide them as basic data of future concept change research. The trends of conceptual change research were analyzed in terms of keywords, year of publication, source of research, purpose of research, subject, area of research, and research method. This study was carried out on a total of 126 conceptual change papers of Earth Science education published from 1989 to July 2017. This study showed the following conclusions: First, the conceptual change research papers used more the term 'conceptual change' than 'misconceptions' and 'preconceptions'. Second, the conceptual change paper has achieved a large amount of growth in the 2000s. Third, conceptual change research tended to proceed to the subject of master's dissertation. Fourth, there were a lot of researches to find out the misconceptions and change them into the right concept, the conceptual change paper used free response test for misconceptions, and cognitive conflict instruction model and CAI (Computer Assisted Instruction) teaching strategy for misconceptions. Fifth, elementary school students were studied the most. Sixth, the study of conceptual changes in the field of Earth Science was high in the astronomical and atmospheric areas. Finally, although quantitative analysis methods were used in the early days of research, in the 2010s, qualitative analysis methods were widely used. In this paper, we proposed research on conceptual change for pre- and in-service teachers, expansion of research on conceptual changes in various fields such as geology, oceanography, atmosphere in Earth Science, investigation of causes of misconception in Earth Science and research on individual's affective factors, and so on.

The present investigation was carried out to determine the qualitative difference between 4 varieties of perilla leaves cultivated Miryang area, particularly focusing on the amino acid composition and flavor compounds. Aspartic acid, glutamic acid, glycine, alanine, arginine, and threonine were the major amino acids, and tyrosine and cysteine and methionine containing sulfur were detected as little amount in protein of all perilla leaves. All perilla leaves contained about 34 kinds of free amino acids, and the major free amino acids were same as the protein bound amino acids. However, no significant difference among 4 varieties of perilla leaves was observed in the profiles of protein bound and free amino acids composition. Flavor compounds analyzed by GC-MSD following to extraction of flavor by SDE (Simultaneous Steam Distillation-Extraction) were detected as 51 kinds from 'Leafy perilla 1', 47 kinds from 'Yupsil perilla', 46 kinds from 'Miryang 9' and 'YCPL. The major volatile compound was perilla ketone, its concentration was $145.75\;{\mu}g/g$ in 'Miryang 9', $187.00\;{\mu}g/g$ in 'YCPL', $301.59\;{\mu}g/g$ in 'Leafy perilla l' and $551.42\;{\mu}g/g$ in 'Yupsil perilla', but the other flavor compounds, 3-hexen-l-ol, trans-2-hexenal, $\beta-caryophyllene,\;\alpha-farnesene$ and etc, were less than $20\;{\mu}g/g$.

This article aims to identify organizational factors that influence the performance of implementation of the U.S. Freedom of Information Act (FOIA) and to investigate the strength and direction of their effects. Explanatory variables include administrative resources, organizational culture, litigation cost, and the complexity of FOIA requests. The study will analyze quantitative secondary data from official statistics of federal agencies and the 2006 Federal Human Capital Survey as well as qualitative data from semi-structured interviews of FOIA officers. The results of statistical analyses are as follows : FOIA funding significantly affects median processing time and number of requests pending. There is a significant relationship between bureaucratic culture and number of requests pending, but not between bureaucratic culture and number of requests pending. There exists a significant relationship between the cost of FOIA litigation to federal agencies and the performance of FOIA implementation. There exists a significant relationship between the complexity of FOIA requests and the performance of FOIA implementation. This study also has important implication in South Korea, which has been under a sharp confrontation with North Korea for more than 50 years. As illustrated by the conflict between people's right to know and national security during the investigation of recent Sinking of the ROKS Cheonan, efforts should be made to prepare legal and institutional mechanism for freedom of information policy which can maintain a balance between conflicting values as well as efficient information disclosure in Korea.

Sustainable development brings many potential advantages to the society and environment. As such, many educational communities have concentrated on incorporating this concept into their educational programs for the K-12 classrooms. The K-12 technology educators have also exerted efforts to infuse the sustainable development concept into the K-12 national-curriculum level. The purpose of this study was to investigate the high school students' attitudes towards sustainable development. The study participants were 1,073 high school students from six high schools in Gyeonggi province. A self-reported instrument was used to obtain the students' demographic information and to come up with an attitudinal scale towards sustainable development. This study employed statistical ways of exploring the attitudinal level of the South Korean high school students and of describing the subcategories of the sustainable development. The findings described the high school students' attitudes towards sustainable development with regard to three components: (1) cognition of sustainable development; (2) practices in pursuit of sustainable development; and (3) perception of the education for sustainable development. The exploratory factor analysis supported three perspectives of the students' attitudes towards sustainable development. Also, the qualitative data collected and analyzed from the students' responses to the open-ended question posed to them indicated two domains of the students' cognition of and practices in pursuit of sustainable development. These findings were made on the bases of several recommendations regarding the research on and implementation of Education for Sustainable Development(ESD).
