The Korean economy successfully overcame the macroeconomic downturns driven from the Asian financial crisis in a very short period of time. The economic shock, however, generated a variety of social problems, one of which was the increase in felonies (homicides, robbery, rape, and arson), or degradation of public safety. We argue that the Korean criminal policy has not been effective to ameliorate the rising trends in crime caused by the financial crisis. In order to substantiate this claim, we assess the effectiveness of criminal policy: policing, sentencing, and corrections. First, there has been resource shortage in policing since the 1997 financial crisis. For the past ten years, the investment of human resource and budget in the police has been virtually stagnant, as well as in prosecutors' investigation activities. The insufficient resource allocation in policing caused a huge decline in arrest rates and prosecution rates. Second, the Korean judicial system has not increased the severity of punishment. Comparing the pre- and the post-financial crisis period, the average length of prison sentence by the courts has declined. Given the degrading in the quality of crime and the decreasing amount of inputs into the policing and prosecution, the government should have increased the severity of punishment to deter crime. Third, we found that the government hired more officers and allocated larger budget into prison and probation. However, it is difficult to suggest that the increased level of resources in correctional programs have been effective in preventing released prisoners from committing future crimes. This is because the number of repeat offenders convicted of more than a third offense increased dramatically since 1997, pushing felonies upward. In sum, the government organizations failed to respond respectively or to make coordinated actions, eventually causing a dramatic increase in crimes. This research brings explicit policy implications. In order to prevent possible additional degradation of public safety, the government must put more efforts into increasing the effectiveness of policy and to investing more resources into said policies. We also emphasize the importance of the institutional mechanisms which foster policy coordination among the Police, the Prosecutor's Office, the Ministry of Justice, and other relevant government organizations.

Recent global warming seems to be dramatic and has influenced forest ecosystems. Changes in phonology of biota, species distribution range shift and catastrophic climatic disasters due to recent global warming have been observed during the last century. Korean forests located mainly in the temperate zone also have been experienced climatic change impacts including shifting of leafing and flowering phonology, changes in natural disasters and forest productivity, However, little research has been conducted on the impact of climate change on forest ecosystems in Korea which is essential to assess the impact and extent of adaptation. Also there is a shortage in basic long-term data of forest ecosystem processes. Careful data collection and ecological process modeling should be focused on characteristic Korean forest ecosystems which are largely complex terrain that might have hindered research activities. An integrative ecosystem study which covers forest dynamics, biological diversity, water and carbon flux and cycles in a forest ecosystem and spatial and temporal dynamics modeling is introduced. Global warming effects on Korean forest ecosystems are reviewed. Forestry activity and the importance of forest ecosystems as a dynamic carbon reservoir are discussed. Forest management options and challenges for future research, impact assessment, and preparation of mitigating measures in Korea are proposed.

Calreticulin (CRT) is one of the major $Ca^{2+}$ binding chaperone proteins of the endoplasmic reticulum (ER) and an unusual luminal ER protein. Postnatally elevated expression of CRT leads to impaired development of the cardiac conductive system and may be responsible for the pathology of complete heart block. In this study, the molecular mechanisms that affect $Ca^{2+}$-dependent signal cascades were investigated using CRT-overexpressing cardiomyocytes. In particular, we asked whether calreticulin plays a critical role in the activation of $Ca^{2+}$-dependent apoptosis. In the cells overexpressing CRT, the intracellular calcium concentration was significantly increased and the activity of PKC and level of SECAR2a mRNA were reduced. Phosphorylation of Akt and ERKs decreased compared to control. In addition the activity of the anti-apoptotic factor, Bcl-2, was decreased and the activities of pro-apoptotic factor, Bax, p53 and caspase 8 were increased, leading to a dramatic augmentation of caspase 3 activity. Our results suggest that enhanced CRT expression in mature cardiomyocytes disrupts intracellular calcium regulation, leading to calcium-dependent apoptosis.

This technical research paper attempts to examine literature therapeutic significance of Sijo. This research analyzes how the therapeutic mechanisms of literature or sentence can be physiologically applied to human nerve system. To study such interactions between therapeutic mechanisms of literature and human physiological mechanisms, diverse on- and offline Sijo activities, such as a Facebook group "Sijoya Nolja", were studied, as well as various publications in literature and medicine. For the three years this research was being conducted, 27 out of 488 Sijo poets debuted through Sinchunmunye, and many have gone professional through various contests. 19 of them became members of Sijo Poet Associations of Korea, with globalization of Sijo in mind. Their aggressive activity proves that the quality of live was elevated through literature therapy. The therapeutic effects are especially dramatic for older authors, and authors with traumatic experience. Through this research, Sijo turned out to be a form of literature with the quickest effect on elevating quality of life. To solve problems such as depression, emotional isolation, and other mental conditions, literature therapy through Sijo should be implemented, and therapeutic approach of literature should be more professionalized.

This study is an attempt to look into the future role of the ROKN and to provide a strategic way forward with a special focus on naval strategic concept and force planning. To accomplish this goal, this research takes four sequential steps for analysis: 1) assessing the role and utility of naval power of ROKN since its foundation back in 1945; 2) forecasting features of various maritime threats to influence the security of Korea in the future directly or indirectly; 3) identifying the roles to be undertaken by future ROKN; and 4) recommending Korean way of naval force planning and the operational concept of naval power. This study seeks to show that ROKN needs comprehensive role to better serve the nation with respect to national security, national prosperity and development, and future battle-space management. To safeguard the national security of Korea, it suggests three roles: 1) national guard for the peaceful unification; 2) protector of the maritime sovereignty; and 3) suppressor to maritime threats. Three more roles are highlighted for national prosperity: 1) escort of the national economy; 2) guardian for national maritime activities; and 3) contributor to the world peace. These roles need to be closely connected with the role for the battle-space management. This paper addresses the need for a dramatic shift of the central operational domain from land to maritime in the future. This will eventually offer future ROKN a leading role for developing strategic concept and force planning rather than merely a supporting one. This study finally suggests 'balanced' strategy both in concept development and force planning. A balanced force planning is a 'must' rather than an 'option' when considering a division of function between Task Fleets and Area Fleets, constructing cutting-edge conventional forces such as Aegis destroyer, CVs, or submarines, and the mix of high-profile platform and low-profile when composing future fleets. A 'balance' is also needed in operational concept. The fleet should be prepared to fulfill its missions based on two different types of force operation i.e., coercive or cooperative application of the utility of naval force. The findings and recommendations of the study are relevant today, and will be increasingly important in the future to achieve various political goals required by enhancing the utility of naval power.

The fish farming using net cages has been developed in many semi-closed bays in the southern coast of Korea for the last two decades. The intensive cage cultures of fishes generate considerable amounts of organic waste in the form of uneaten food and faeces. In order to evaluate the effect of fish farming activities we collected the benthic macrofauna near the fish farm area located in Wolho Islet of Gamak Bay and in Haklim Island of Tongyeong in November 1998. Benthic macrofaunal assemblages showed dramatic changes in species number, species diversity, and faunal abundance in the region of the fish farm. These changes were clearly observed even at a distance of up to 30 m from the fish farming cage area. Within 5 m from the cage, there was a zone with low species diversity and highest density, dominated by opportunistic polychaete worm, Capitella capitata. By a distance of 15-30 m, this zone presents highest species number and higher density. Our results clearly demonstrated that fish farm area was highly enriched with organic materials, and implied that the fish farm industry and adjacent benthic ecosystem in semi-closed bay will be seriously damaged by self produced organic wastes in the near future.

This study aims to analyze the continuity and sequence between the intelligent life curriculum for grades 1-2 and the science curriculum for grades 3-4 with a focus on knowledge and inquiry process skills. The results demonstrate that contents related to science in the intelligent life curriculum consisted of only 10 out of 32 elements. Five elements were related to the science curriculum for grades 3-4 and limited to the 'life sciences' area. Particularly, the intelligent life curriculum did not address topics related to 'matter' and 'motion and energy'. Developmental connection was established in the 'life sciences' area and dramatic changes were noted for the topics related to 'earth and space' area. In terms of inquiry process skills, the levels of observation, measurement, inference, and communication naturally increased, whereas a developmental connection was noted between the intelligent life and science curricula. Classification can be viewed as a developmental link; however, viewing the classification as scientific from the epistemic perspectives was insufficient. In the case of expectation, a gap was observed in both curricula due to the absence of expectation activities in the intelligent life curricula. The study discussed the implications for securing the connection between the intelligent life and science curricula on the basis of these results.

The purpose of this study is to explore the implementation of Bibliodrama on the metaverse platforms. In other words, to create interesting and effective Bible education for modern learners, this study took a didactical approach to the implementation of Bibliodrama through the metaverse. The main reason to be enthusiastic about using the metaverse for education is because users, who have been only content consumers, now able to experience and create values. As a Bible didactical approach, Bibliodrama is a an emphatical and communicative learning method in the form of role play. Bibliodrama seeks to interact with the world of the learner and the world of the Bible through improvisational acting, to study the Bible. Through the Bible didactical approach, the meeting of Bibliodrama and the metaverse can have a positive effect on modern learners, in terms of improving learning environment and, above all else, increasing learning interest. In terms of biblical didactics, implementing Bibliodrama in the metaverse has the following advantages. First, it helps to construct a dramatic situation and environment so that the meaning of the biblical text can be proved relevant to today's learners, not something belonging to the past. Second, in the metaverse, the historical space and characters of the Bible can be realized in virtual reality to produce a 'situational play'. Demonstrating freedom, imagination and creativity in the metaverse learners play in Bibliodrama. This way they also become aware of the hidden meaning of the blank pages in the Bible. Third, the metaverse environment is not static but dynamic and interactive; Bibliodrama pursues an interpretation that harmonizes spirit and body. Therefore, through the dynamic activities of discovering the meaning and significance of the Bible, it is possible to form a holistic faith in which spirit and body act as one.

With the dramatic development of science and technology since the twentieth century, attempts to overcome human's natural and physical limitations through technology have actually reached a peak. Transhumanism is a movement that strongly affirms these human technological attempts. However, this optimistic belief of transhumanism in technology meets the strong resistance of opponents contending that transhumanism might destroy human nature and severely undermine human values and rights. The focus of the transhumanism debate lies in what technology means to humans. However, in order to exactly grasp the essence of transhumanism, we should first consider our 'life-world', where technology and humans are closely intertwined. The word 'life-world(Lebenswelt)' which originally comes from Husserl, is an open and universal world as a horizon that is the basis of all human practical activities and at the same time encompasses its products in itself. According to Husserl, the process of incorporating human products into the life-world is a kind of 'familiarization' process through which specific theories and techniques are harmonized with our lives in the life-world. Such harmonization and familiarization of technology could be also considered a humanization of technology. It is a process in which technology is assimilated and corresponds to the finiteness of human and the life-world. In this sense, we could say that the transhumanistic attempts are just a natural expression of human desire to be perfect in the life-world and that they should not be overly concerned or overestimated.

This paper reexamines the formation process of Ch'anggŭk, Korea's musical drama based on p'ansori in the 1930s, focusing on the Ch'anggŭk gramophone records and the repertoire of the Chosŏn Sŏngak Yŏn'guhoe(Korean Vocal Music Association). The paper discussed the achievements and limitations of the Chosŏn Sŏngak Yŏn'guhoe which was at the center of the formation of Ch'anggŭk by examining the activities of the Chosŏn Sŏngak Yŏn'guhoe in the 1930s. The role of 'ipche-chang' and 'narrator' in the Ch'anggŭk gramophone records was seen as Ch'anggŭk imagination that was realized by the members of the Chosŏn Sŏngak Yŏn'guhoe who recognized the 'dramatic space and stage', which is distinct from p'ansori, Korean traditional vocal and percussion music. In addition, the paper discussed the difference and meaning of the concept of 'Sin-Ch'anggŭk' between Seo Hang-Seok and Song Seok-Ha, which is derived from the Ch'anggŭk formation. The performance of stage Ch'anggŭk in the 1930s was a repetition of the discussion that it should reach a point of Kagŭk, music or song dramas. This paper discussed the process of replacing the term 'Ch'anggŭk' with 'Kagŭk' at the time, and examined the way Ch'anggŭk stage was established as a perfect form during the process. The formation of Ch'anggŭk by members of the Chosŏn Sŏngak Yŏn'guhoe could be an important achievement in the history of Ch'anggŭk, but there was no choice but to reveal the limitation in the formal aspect due to the 'refinement' and 'exclusion' according to the cultural policy of Japan. P'ansori musicality was enhanced, but it could not contain the spirit and diversity of the times, so it could be said that there was no choice but to stop as a rudimentary creative imagination of Ch'anggŭk. Ch'anggŭk is a genre that is inherently limited, but the limitation can be overcome over the times, which will be covered in a subsequent paper.
