Seasonal population changes in Laodelphax striatellus Fallen (small brown planthopper), percentage of rice black-streaked dwarf virus (RBSDV) viruliferous L. striatellus, and RBSDV infection of 11 corn hybrids were observed at various locations and years. The population size of L. striatellus was relatively small in the middle parts of Korea, but it was much greater in the southern areas. The population size of the first generation of adult L. striatellus emerged from late April to early May was similar or smaller compared with that of the second generation emerged in middle June in the middle parts of Korea. However, in the southern areas the population size of second generation was much greater than the first generation. The percentage of RBSDV viruliferous L. striatellus differed depending on the years, locations, and testing methods. The percentage of viruliferous vector was highest in southern plain areas and it tended to decrease with distance from the areas. The percentage of viruliferous vectors tested by enzyme-linked immunosorbent assay was higher than that tested by rice seedling test. The RBSDV infection rate of corn hybrids was highest at Daegu and ranged from 9 to 39% probably due to both a higher L. striatellus population and a higher percentage of viruliferous vectors. However, it was significantly lower in other areas and ranged from 0 to 13%.

This study aims to provide data on attitudes towards the use of Homecare beauty devices in correlation to narcissism of women between ages 30-59. Through statistical analysis of 563 survey questions, data displayed that respondents' age, level of education, marital status, economic status, and career status showed a strong correlation with implicit narcissism, while explicit narcissism only showed a correlation with age and career status. The most popular skincare location was shown to be 'self-provided at home', and the most popular item purchased being 'galvanic devices'. Secondly, attitudes towards the use of homecare beauty devices in correlation towards implicit narcissistic respondents were only to the consideration of its use, while explicit narcissists displayed a strong correlation between the purchase of a product and the recommendation of others. While this is the first study on attitudes towards homecare beauty devices in relation to a personality-based trait like narcissism and it displayed meaningful results, a more in-depth study in the future dealing with a larger region and respondent groups of a wider age and gender group should be undertaken.

본 연구에서는 고향의 개념을 의미론적 측면과 지리학적 입장에서 정의하고, 한국 사람들이 고향이라고 지칭하는 고향의 공간적 대상, 고향에 대한 감정과 선호, 고향의 지리적 특징 및 이미지 등을 조사하여, 이를 중심으로 한국인의 고향에 대한 애착의 본질과 정서(ethos)를 밝히려 하였다. 그 결과는 다음과 같다. 첫째, 한국인의 고향에 대한 애착은 본질적으로 고향 의식과 회귀본능과 같은 고향에 대한 인류의 보편적 정서로부터 나온 것이다. 둘째. 이러한 보편적 정서 위에 한국의 사회적 배경에서 나오는 고유한 고향의식이 첨가되었다. 사회적 배경에서 발생된 고향에 대한 강한 애착은 효에 근본을 둔 유교적 전통, 남북분단, 도시화에 따른 광범위한 실향의 결과에 의해서 형성된 정서라고 볼수 있다. 섯째, 고향이미지는 이러한 한국의 정서를 반영하고 있으며, 자연환경적, 인문환경적, 감각적 요소가 모두 수렴된 전형적이며, 추상화된 유형으로 나타난다. 넛째, 한국인의 고향에 대한 정서는 인간의 본성으로부터 나오는 보편적 정서와 대체로는 일치하지만 개인이나 집단의 인구.사회적 배경과 공간적 체험에 따라 다른 것으로 나타났다.

Seokchon Lake, and the area surrounding it, have become symbolic with an environment of 'peace', 'delight', 'happiness', and 'healing' due to the large floating yellow rubber duck which sits within the lake. There exists, however, a hidden intention of a large corporation who wishes to make benefit of this installation and its healing properties. Nevertheless, the lake has become a hot destination for people to come and see the rubber duck and take romantic photos with it. The photographs taken and shared further expand the popularity and romantic environment of the duck and lake. This process is a perfectly hermeneutic circle. Self or group mediation through photographic performances with the rubber duck has allowed the lake to take on new meaning to visitors. For families taking photos together it has become a place of family bonding and love while for couples of any age it has been transformed into a place to express their love through pictures together with the duck. Even for selfie generation it has become a destination and muse. Tourists are not merely written upon, but are also enacting and inscribing places with their own stories. Therefore, photographic performances produce rather than consume and reflect geography of Seokchon lake.

It is generally reported that field learning and a class using regional materials motivate learning and give a positive effect on learning of geology unit, science subject. The purpose of this study is to develop and to suggest regional materials for learning of geology unit, science subject at Jaeundo. The results of this study are as follows. Regional materials were developed at three locations (namjin dockyard area, yangsan beach area and dunjang beach area) of the study area. Namjin dockyard area (A site) is composed of terrain of sea cliff, sand beach and mud flat. Sedimentary rocks, weathering phenomenon of rocks and strata of various shape are distributed in sea cliff of A site. Yangsan beach area (B site) is composed of coastal terrain as sea cliff and sand beach about 1.5km long. Sedimentary rocks and rhyolite are distributed in sea cliff of B site. Tafoni formed by weathering process of rocks are developed on sedimentary rock outcrop of B site. Dunjang beach area (C site) is composed of coastal terrain of sea cliff, sand beach about 2km long and sea stack. Stratified sedimentary rocks are distributed in sea cliff of C site. Sea stack located in near halmi island on the west side of dunjang beach area is a good sample showing erosion process of sea cave for a long time. Unique geomorphology and geology phenomena distributed in 3 sites at Jaeundo can be used as regional materials for learning of geology unit, science subject. And, Regional materials shall be used in conjunction with the text book data of geology units. These 3 sites of the study area are worth using as field learning course for elementary and middle school students.

In this paper, we propose a barrier-free course route navigation service named "Theme Road" aimed at improving the mobility and convenience for elderly electric wheelchair users with walking disabilities. To achieve this goal, we conducted a user survey through shadowing and in-depth interviews to gather insights on the challenges experienced by elderly electric wheelchair users. We identified potential solutions for each inconvenience through co-creation workshops, resulting in a set of design considerations and app functionalities. Using persona development and service scenarios, we designed and implemented the "Theme Road" service as a dedicated navigation application for barrier-free course navigation. Unlike conventional route navigation and mapping services, our study stands out by offering a unique approach that combines recommended destinations and safe routes based on experiential analysis from elderly electric wheelchair users.

This article examines the sexualization of place under conditions of the compressed modernization and reflexive cosmopolitanism. In particular, I adopt Michel de Certeau's spatial didactic model of strategy and tactic to investigate the dynamics at play in the gay labelling of a Coffee Bean & Tea Leaf (Coffee Bean) in South Korea, and explore the 'gaying' that takes place within preconceived heteronormative space. Using interview data, I additionally explore the negotiation tactics and coping mechanisms at work when gays compete with heterosexuals for non-gay place. The results illustrate how gays gay in heteronormative space and how heteronormative space harmoniously embodies gay men. The findings suggest that spatial location and tactic play important roles in stimulating compromise of sexual territory. Gay Bean benefits from being nestled between locations with histories of tolerance, while it also prospers from reflexive cosmopolitan ideals of diversity and acceptance of others. Gay identity and gaying is interpreted as foreign in Korea, which buttresses gay performativity in spaces welcoming of foreigners and so-called "deviance." However, how gaying functions within place relies not only on spatial histories of tolerance outside, but also on the tactics of identity negotiation within. The findings suggest that spatial and tactical conditions induce gay individuals to police other gay-identified individuals when gays gay in so-called heteronormative places.

동굴은 우리의 옛 조상들이 강 가까운 동굴 속에 살면서 바닷가나 냇가에서 물고기를 잡아먹으며 살아가는 등 먼 옛날 석기시대에는 혈거생활의 주거지로 이용되어 왔을 뿐만 아니라 그 후 인류가 발전함에 따라 다양하게 이용되어 왔다. 즉, 때로는 은신처로 이용되어 왔고 때로는 묘지로, 작전기지로, 그리고 물자의 저장고로도 이용되었고 그밖에 수양터와 신앙의 장소 등으로 사용되었었다. 이러한 증거로서 인골화석, 생활을 위해 선조들이 사용하였던 다량의 도구 등 일상용품이 아직도 보존되어 남아있는 것이 발견되고 있다. 우리 나라에서 가장 독특한 문화를 갖고 있는 제주도에서도 여러 개의 동굴이 발견되었다. 이들은 성인상으로는 모두 제주도의 화산 폭발과 관련된 것이어서 용암동굴로 분류되고 있다. 그 중에서 삼성혈은 제주도의 삼성신화, 즉 부족 형성과 관련 있는 것이고, 빌레못동굴은 구석기시대에도 재주도가 주거지로 이용되었음을 인증 받는 중요한 자료로 활용되고 있다. 또한 김녕사굴의 설화는 재주도 설화의 하나로서 제주도 정부와 주민들간의 일치단결에 대한 예를 보여주고 있으며, 산방굴은 제주도 여인들의 기개에 대한 예를 나타내 주는 곳이고, 세계에서 가장 긴 동굴군계인 만장굴은 여인의 한을 전설로 담고 있다. 이렇듯이 동굴은 인류와 매우 밀접하게 관련되어 있음을 확인할 수 있다. 따라서 이제 동굴은 그 학술적ㆍ문화적 가치로서는 물론 최근에 붐이 일고 있는 관광적 측면에서도 그 보전 및 연구ㆍ개발이 시급하다 하겠다.
