The paper introduces US Indo-Pacific Strategy and discusses its meanings and implications for international security and our strategy. It tries to look at the Indo-Pacific strategy(IPS) through the lenses of international political theories. The paper provides three important observations. First, the US Indo-Pacific strategy is a declaration of the national identity of the US as an Indo-Pacific nation. The paper argues that the IPS reflects the US leadership that would facilitate the formation of, so called, the Indo-Pacific community. In arguing these points, the paper notes that the IPS has rich elements of constructivist approaches including norms and national identity. Second, the paper observes that the IPS report serves as an effective deterrent strategy. The IPS does not call out China as an enemy. But, it tries to deter against a range of actors including China by warning that whoever violates the rules-based order in the region would have consequences. Third, the paper maintains that the IPS is an effort by the US to mitigate the risk of a great power war between the US (an established power) and China (a challenging power) because the IPS articulates the United States's willingness to work with China as long as it plays by the rules. There will be challenges to the US and other countries in the region including South Korea particularly because of economic interdependence. However, the paper argues that the IPS stands for an optimistic sign of the future security in the Indo-Pacific region because it is a manifestation of the US for its national will to defend the status quo characterized as Pax Americana which has been maintained since the end of the Second World War. It also argues that South Korea also can, and should make the most of this opportunity by enhancing our capacity in national defense.

Regulation theories has paid little attention to spatial regulation processes, while it has focused on economic and social regulation processes. More specifically, there have been little researches on regulationist approach to the transformation of the post-socialist system in the context of the space economy. Therefore, the article has attempted to conceptualize the transformation of space economy under the post-socialist system in the light of regulation theories. The space economy could be regarded as the foundation of the reproduction of social relations. Thus, the transformation of post-socialist system has led to the fundamental changes in enterprise and industrial networks as well as social relations in spatial contexts. In this perspective, the research has attempted to identify 'the mode of enterprise regulation' regarded as a codified firm networks by investigating intra-, inter- and extra-firm relations associated with the transformation of post-socialist system. Also, it has intended to suggest three types of the space economy - (1) disembedded economies based on the isolated networks and dissolution of pre-existing networks, (2) embedded economies based on the interaction of institutions and restructuring of networks, and (3) over-embedded economies based on the insulated institutions and endurance of pre-existing networks-in accordance with the governance, institution and networks in the post-socialist system.

In this study, mathematical analysis is conducted by focusing to the 'size' of the 'point' and the 'line'. The textbook descriptions of the 'point' and the 'line' in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum and US geometry textbooks were compared and analyzed between. First, as a result of mathematical analysis of' 'the size of a point and a segment', it was found that the mathematical perspectives could be different according to 1) the size of a point is based on the recognition and exclusion of 'infinitesimal', and 2) the size of the segment is based on the 'measure theory' and 'set theory'. Second, as a result of analyzing textbook descriptions of the 'point' and the 'line', 1) in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum, after presenting a learning activity that draws a point with 'physical size' or line, it was developed in a way that describes the 'relationship' between points and lines, but 2) most of the US geometry textbooks introduce points and lines as 'undefined terms' and explicitly states that 'points have no size' and 'lines have no thickness'. Since the description of points and lines in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum may potentially generate mathematical intuitions that do not correspond to the perspective of Euclid geometry, this study suggest that attention is needed in the learning process about points and lines.

This paper examines the characteristics of the May 18th (5 18) Gwangju Democratization Movement archives to suggest a collection development strategy for the May 18th archives collection network. Individual public and civilian archives collecting the May 18th archives separately should form a cooperative collection network based on documentation strategy. Most of all, May 18th archives are human rights records and should be understood and collected as human rights records. International principles support the collection of the May 18th archives as human rights archives by prohibiting destruction of relevant temporary records and encouraging the victims' right to access to their records. As the May 18th archives were mostly produced by many multiple agencies, this multi-provenance and diversity of the records necessitate the building of an archives portal for the records registries and online search. To document the undocumented past and the victims, the collection network should focus on oral history project as a major part of its collection development strategy. Finally, the May 18th archives collection network should build a cooperative relations with the unwilling public agencies which have the archives holdings. Therefore, the collection development strategy should include advocacy and awareness activities for promoting cooperation from these public agencies and public archives, and the people in general.

This study traced the origin and transformation of word library linked with archives in the ancient Near East, and Greece and Rome. First, the word library has two origins. One is derived from the Latin bibliothēkē from the ancient Greek βιβλιοθήκη. The first trace is Pollux's Onomasticon in the second half of the 2nd century, and if considered as a set of literature texts, it is Lipsius's De Bibliothecis Syntagma in 1602. The other was established as an library in the early 14th century after Latin libraria (or librarium) was translated into Old French librairie (or librarie). The word library was coined by Chaucer in 1374. Second, the clay tablet repository that existed in the ancient Near East is close to an archive, but the official name is unknown. However, the Ashurbanipal clay tablet archive is far from the principle of respect for original order and origins emphasized by the archivists, so it is not a royal archive, but a prototype of the royal library. And the official name of the Library of Alexandria was 'Βιβλιοθήκη της Αλεξάνδρειας', and then it was changed to 'ALEXANDRINA BYBLIOTHECE'. Third, In ancient Greece and Rome, archives and libraries were separated. Greece libraries were at the level of a small libraries attached to gymnasiums, and had few independent titles. The names of the Roman libraries often attached to the public baths were mixed with βιβλιοθήκη and Bibliotheca. Finally, the ancient library was succeeded to the cathedral bibliothek, and was transformed into 'bayt al-hikmah' in the Islamic Empire. In Japan, China, and Korea, Japanese-Chinese word library was accepted at the end of the 19th century, but there are many issues that require follow-up research.

3D point cloud semantic segmentation is a computer vision task that involves dividing the point cloud into different objects and regions by predicting the class label of each point. Existing 3D semantic segmentation models have some limitations in performing sufficient fusion of multi-modal features while ensuring both characteristics of 2D visual features extracted from RGB images and 3D geometric features extracted from point cloud. Therefore, in this paper, we propose MMCA-Net, a novel 3D semantic segmentation model using 2D-3D multi-modal features. The proposed model effectively fuses two heterogeneous 2D visual features and 3D geometric features by using an intermediate fusion strategy and a multi-modal cross attention-based fusion operation. Also, the proposed model extracts context-rich 3D geometric features from input point cloud consisting of irregularly distributed points by adopting PTv2 as 3D geometric encoder. In this paper, we conducted both quantitative and qualitative experiments with the benchmark dataset, ScanNetv2 in order to analyze the performance of the proposed model. In terms of the metric mIoU, the proposed model showed a 9.2% performance improvement over the PTv2 model using only 3D geometric features, and a 12.12% performance improvement over the MVPNet model using 2D-3D multi-modal features. As a result, we proved the effectiveness and usefulness of the proposed model.

The present study was conducted to (1) explore the perceptions of Korean men and women about what is an important relationship for them and how do each gender group construe relational self, and (2) develop the scale to assess the factors of relational self and verify construct validity of the scale. 40 college students and 60 adults participated in survey and FGI (Focused Group Interview) respectively, and content analysis of their responses yielded 2 categories with 39 characteristics of relational self. The one category was named 'instrumentality' which was important to men and the other was named 'expressivity' which was important to women. The list of 39 items was administered to a nationwide sample of 1503 Korean adults to assess their construal of relational self through the 6-point Likert scale. Principal axis factor analysis showed that the two categories were unidimensional with high reliability. As a result of factor analysis on each category, a total of 9 factors were extracted. Specifically, the instrumentality consisted of factors such as utilitarianism, independence, initiativeness, self-assurance, and competence. And the factors of expressivity were empathy, passiveness, dependency, consideration. The tests of mean difference revealed that men had higher scores in most of the instrumental factors, while women had higher scores in most of the expressive factors. But there was no sex difference in the interdependent self-construal scale(Cross, 2000) which has been frequently used for measuring relational self. This is related to the Korean's collective cultural characteristics, and it was concluded that the relationship with others is very important to both Korean men and women, but the meaning and expectation of the relationship as well as the method for its preservation are different to each sex group. In addition, the correlation analyses indicated that the feminity score was positively correlated with the expressiveness while the masculinity score was positively correlated with instrumentality. This result implicated the differences of relational self among Korean people were related to the socialization process of each sex, i.e., sex role identity. Finally, limitations of this study and the directions for future research were discussed.

During the process of modernization, many rural villages in Korea have experienced degeneration and breakdown, losing sustainability. However, Oeam village in Asan City, South Chungcheong Province (State-designated cultural heritage, Important Folk Material No. 236) has established itself as a unique folk village, which evolves with sustainability, pursuing the revival of Neo-traditionalism. Oeam village is a tribal village of the Yis from the Yean region and has maintained environmental, economic, and social sustainability and soundness for over five centuries. Thus, the village has sustained itself well enough to be a cultural asset with 'Outstanding Universal Value', in terms of its value as world cultural heritage. The village maintains its own identity, filled with a variety of traditional and scenic cultural assets that symbolize a gentry village. Those assets include Confucian sceneries (head family houses, ancestral shrines, tombs, gravestones, commemorative monuments, and pavilions), various assets of folk religion (totem poles, protective trees at the entrance of a village, shrines for mountain spirits, village forests), tangible and intangible cultural assets related to daily lives (vigorous family activities, rigorous ancestral rituals, family rituals, collective agriculture and protection of ecosystem), which have all been well preserved and inherited. In particular, this village is an example of a well-being community with a well-preserved folksy atmosphere, which is based on environmentally sound settlements (nature + economy + environment + community) in a village established according to geomancy, East Asia's unique principle of environmental design. In addition, the village has kept the sustainability and authenticity for more than 500 years, combining restraint towards the environment and the view of the environment which respects the natural order and cultural values (capacity + healthy + sustainability). Therefore, the Oeam folk village can be a representative example of a folksy and scenic Korean community which falls into the category of IV (to exemplify an outstanding type of building, architectural or technological ensemble, or landscape which illustrates significant stages in human history) and V (to exemplify an outstanding traditional human settlement, land-use, or sea-use which is representative of cultures, or human interaction with the environment especially when it has become vulnerable under the impact of irreversible change) of Unesco's World Cultural Heritage.
