The main focus of the study is to find out the origin of the case management in social work and relevant background and context around it, by using the method of genealogy, an historical framework or perspective developed by Foucault, French social philosopher. The reasons of the study are two fold : First, why the case management can be established as a major strategy of social work field in such a very short time. Second, since the case management has been accepted, why it has been reported ceaselessly that a lot of case managers have experienced the severe stress and sufferings in carrying out the case management practice. The results of the study shows that the case management is partly a very social device needed in the late 20th century to manage the social work resources and manpower efficiently, which might be against the genuine social work's mission and idealism. In a conclusion, to retrieve the genuine identities of social work profession, not only the practice case management should be cautious to tendency of management and control inherited in it but also be balanced by the traditional ideals of human emancipation and liberation.

In order to improve functionality of kochujang which is one of the traditional foods in Korea, sea tangle powder(2, 4, 6 and 8% sea tangle powder on the glutinous rice weight basis) was added to the raw material of kochujang and then investigated the bacterial counts and enzyme activities with control kochujang during the fermentation at 3$0^{\circ}C$ for 120 days. Bacterial count was about 10$^4$ cfu/g at initial stage of fermentation and then maintained 10$^{8}$ cfu/g after 60 days of fermentation. $\alpha$-amylase activity was gradually reduced during fermentation periods, so the activity was lost almost at late of fermentation $\beta$-amylase activity was rapid increased until 30 days of fermentation and the rapid decreased at 60 days of fermentation and after 90 days was slightly decreased. Activities of acidic protease and neutral protease were increased until 30 days of fermentation and then these were shown irregularities decreased.

This paper examines university patenting activities as a commercialization of academic research. It shows how a number of university patents increase exponentially and how that can be, especially in terms of role of the state. In the late 1990, the Korean government supports the new vision of 'technological innovation' in establishing a science and technological policy and begins to perceive the importance of university R&D to overcome the economic crisis. Thus, an administrative, financial, and legal systems which support the university R&D are organized and the governmental grants for R&D increase exponentially, especially in promising new technologies(6T). Also, an institution for managing intellectual property rights is established in university. Universities assess professor's performance in terms of patent and license to encourage patenting activities. Thus the number of patents and its productivity increase exponentially. But the increase in patents takes place only to a dozen of universities, this means that a Matthew effect does work.

This study first examined the social meanings of typicality found in the prison, (solitary) confinement, and conduit(passage) in Peter Halley's works, in which both the prison and (solitary) confinement represent a suppressed structural framework. The former has freedom and escape excluded from it, and the latter allows for mutual regulation and connection as a space of positive mediation. Conduits are interpreted to be flexible and have the potential of creating something new through connection and communication with the outside world. The study then compared and analyzed the meanings of typicality in Halley's works and the concept of segments proposed by Gilles Deleuze and Félix Guattari as social justice in that both of them were in the same context. The findings lead to a conclusion that Halley's prison, (solitary) confinement, and conduit(passage) can be connected to a solid, flexible, and escape segment, respectively, by Deleuze and Guattari.

An electrocardiogram (ECG) is one of the most important biosignals, and in particular, continuous ECG monitoring is very important in patients with arrhythmia. There are many different types of arrhythmia (sinus node, sinus tachycardia, atrial premature beat (APB), and ventricular fibrillation) depending on the cause, and continuous ECG monitoring during daily life is very important for early diagnosis of arrhythmias and setting treatment directions. The ECG signal of arrhythmia patients is very unstable, and it is difficult to detect the R-peak point, which is a key feature for automatic arrhythmias detection. In this study, we develped a continuous measuring Holter ECG monitoring device and software for analysis and confirmed the utility of R-peak of the ECG signal with MIT-BIH arrhythmia database. In future studies, it needs the validation of algorithms and clinical data for morphological classification and prediction of arrhythmias due to various etiologies.

Despite the advantage of unlimited access, there are insufficient studies for the accuracy and stability of FKP that blocks the spread of the system for various applications. Therefore, we performed a long-term analysis from continuous real-time positioning, and investigated the error characteristics dependent on the size and the surrounding environment. The FKP shows significant changes in the positioning accuracy at different times of day, where the accuracy during daytime is worse than that of nighttime. In addition, the size and deviation of FKP correction may change with the ionospheric conditions, and high correlation between ambiguity resolution rate and the deviation of correction was observed. The receivers continuously request the correction information in order to cope with sudden variability of ionosphere. On the other hand, the correction information was not received up to an hour in case of stable ionospheric condition. It is noteworthy that the outliers of FKP are clustered in their position with some biases. Since several meters of errors can be occurred for kinematic positioning with FKP, therefore, it is necessary to make appropriate preparation for real-time applications.

Two distinctive Mesozoic hydrothermal systems occurred in South Korea: the Jurassic/Early Cretaceous(ca. $200{\sim}130$ Ma) deep-level ones during the Daebo orogeny and the Late Cretaceous/Tertiary(ca. $110{\sim}45$ Ma) shallow hydrothermal ones during the Bulgugsa event. The Mesozoic hydrothermal system and the metallic mineralization in the Korean Peninsula document a close spatial and temporal relationship with syn- to post-tectonic magmatism. The calculated ${\delta}^{18}O_{H2O}$ values of the ore-forming fluids from the Mesozoic metallic mineral deposits show limited range for the Jurassic ones but variable range for the Late Cretaceous ones. The orogenic mineral deposits were formed at relatively high temperatures and deep-crustal levels. The mineralizing fluids that were responsible for the formation of theses deposits are characterized by the reasonably homogeneous and similar ranges of ${\delta}^{18}O_{H2O}$ values. This implies that the ore-forming fluids were principally derived from spatially associated Jurassic granitoids and related pegmatite. On the contrary, the Late Cretaceous ferroalloy, base-metal and precious-metal deposits in the Taebaeksan, Okcheon and Gyeongsang basins occurred as vein, replacement, breccia-pipe, porphyry-style and skarn deposits. Diverse mineralization styles represent a spatial and temporal distinction between the proximal environment of subvolcanic activity and the distal to transitional condition derived from volcanic environments. The Cu(-Au) or Fe-Mo-W deposits are proximal to a magmatic source, whereas the polymetallic or the precious-metal deposits are more distal to transitional. On the basis of the overall ${\delta}^{18}O_{H2O}$ values of various ore deposits in these areas, it can be briefed that the ore fluids show very extensive oxygen isotope exchange with country rocks, though the ${\delta}D_{H2O}$ values are relatively homogeneous and similarly restricted.

This study advances research on new venture by taking the organizational ecology perspective to explore the relationship between social legitimacy and new venture performance. We examine how entrepreneurs' organizing activity and social norm shape the social legitimacy. This paper also categorizes the social norms into three parts: social norm that is 1) supporting success achieved through one's own effort 2) encouraging start-up, and 3) promoting risk-taking. Using a dataset of PSED(Panel Study of Entrepreneurial Dynamics) from 2005 to 2011, we found that entrepreneurs' organizing activity has a positive effect on new venture performance. In addition, this study presents the moderating effects of 'liability of newness' that decreases the effect of organizing activity on new venture performance. Interestingly, with respect to the social norm, 'liability of newness' only moderates the relationship between start-up encouraging social norm and new venture performance.

Functional Magnetic Resonance Angiography (fMRA) was a technoscientific innovation that allows scientists to directly view the changes made in the blood vessels of a brain. fMRA was first developed at Neuroscience Research Institute (NRI) in Korea. fMRA mainly utilizes 7 Tesla MRI technology, and NRI is equipped with the instrument. First article on fMRA was published in 2008, and two more papers in 2010 and 2012 consecutively had been published on the newly developed technique. However, fMRA is a competitive technology with existing fMRI. Both techniques capture microvascular changes in a brain, and by doing it, both techniques visualize the cognitive and affective changes. fMRI technology was introduced by Seiji Ogawa in the early 1990's and has been widely used since then. In contrast, fMRA was a newer technology and rather unknown. Developers of fMRA in NRI used series of signifiant-politics in order to make it better known to scientific community as well as public. By resetting the boundaries of existing concept of fMRI, they tried to lower the threshold of a new concept/technique. This case study shows how technoscientists use semiotic strategies governing new technology.

This article tries to identify the regulating mechanism of the welfare states on the private spheres of individuals and families. When the welfare state is to be understood as an institutional arrangement which is based upon the 'modernity', the reflectivity on the welfare state is about to be on the modernity and on the institutions as well. Authors assume the welfare state as an historical and developmental type of modern states. The critical components of modernity embedded in birth and growth of modern welfare states projected to their institutions are identified. Welfare states dissociates the political dynamics which have built the foundation of the welfare state itself, and faces against the new political dynamics of the individualized society. Finally, welfare state confronts the institution failure due to its intrinsic characteristics, and consequently individuals and families come across the institution dependency. Individuals in the overly rationalized spheres are being depoliticized, and they are identified themselves as the subjects of status-struggles of the institutions other than the subjects of the political dynamics of welfare states.
