The objective of this paper is to present how to use Grounded Theory Methodology for conducting a literature review that produces new insights and conceptualizations. In this paper, we have employed Wolfswinkel et al.(2013)'s method, which is called by Grounded Theory Literature-Review Method, for a rigorous literature review. We have utilized this method to capture the concept and insights of individuals' shadow wok in digital environments. By analyzing the relevant literature based on Wolfswinkel et al.'s guide, we have extracted 73 codes in the coding steps and finally showed 12 categories by incorporating similar concepts from those codes. Based on the categories, we end this paper by developing the academic definitions of shadow work in digital environments.

The Fourier transform plays a central role in the theory of distribution on Euclidean spaces. Although Lebesgue measure does not exist in infinite dimensional spaces, the Fourier transform can be introduced in the space $(S)^*$ of generalized white noise functionals. This has been done in the series of paper by H.-H. Kuo [1, 2, 3], [4] and [5]. The Fourier transform $F$ has many properties similar to the finite dimensional case; e.g., the Fourier transform carries coordinate differentiation into multiplication and vice versa. It plays an essential role in the theory of differential equations in infinite dimensional spaces.

To understand the interaction of a fluid and a rigid body, we use the concept of B-evolution. Then in a similar way to the usual Navier-Stokes system, we obtain a Helmholtz type decomposition. Using B-evolution theory and the decomposition, we work on the semigroup to analyze the linear part of the system.

This study is aimed at grouping the academic lines of Korean Oriental Medicine into academic schools. The standard that can be used to classify the academic schools of Korean Oriental Medicine is first of all, identical theory; secondly, similar trend in compiling medical text; and thirdly, having the same individual body of theory. In this paper, based on these three criterion, the lines have been divided into 15 academic schools.

The Reidemeister orbit set plays a crucial role in the Nielsen type theory of periodic orbits, much as the Reidemeister set does in Nielsen fixed point theory. Extending our work on Reidemeister orbit sets, we obtain algebraic results such as addition formulae for irreducible Reidemeister orbit sets. Similar formulae for Nielsen type irreducible essential orbit numbers are also proved for fibre preserving maps.

The Reidemeister orbit set plays a crucial role in the Nielsen type theory of periodic orbits, much as the Reidemeister set does in Nielsen fixed point theory. Let f : G $\longrightarrow$ G be an endomorphism between the fundamental group of the mapping torus. Extending Jiang and Ferrario's works on Reidemeister sets, we obtain algebraic results such as addition formulae for Reidemeister orbit sets of f relative to Reidemeister sets on suspension groups. In particular, if f is an automorphism, an similar formula for Reidemeister orbit sets of f relative to Reidemeister sets on given groups is also proved.

Relevance has a long history of scholarly investigation and discussion in information science. One of its notable concepts is that of 'user-based' relevance. The purpose of this study is to examine how users construct their perspective on the concept of relevance; to analyze what the constituent elements (facets) of relevance are, in terms of core-periphery status; and to compare the difference of constructions of two groups of users (information users vs. information professionals) as applied with a social representations theory perspective. Data were collected from 244 information users and 123 information professionals through use of a free word association method. Three methods were employed to analyze data: (1) content analysis was used to elicit 26 categories (facets) of the concept of relevance; (2) structural analysis of social representations was used to determine the core-periphery status of those facets in terms of coreness, sum of similarity, and weighted frequency; and, (3) maximum tree analysis was used to present and compare the differences between the two groups. Elicited categories in this study overlap with the ones from previous relevance studies, while the findings of a core-periphery analysis show that Topicality, User-needs, Reliability/Credibility, and Importance are configured as core concepts for the information user group, while Topicality, User-needs, Reliability/Credibility, and Currency are core concepts for the information professional group. Differences between the social representations of relevance revealed that Topicality was similar to User-needs and to Importance. Author is closely related to Title while Reliability/Credibility is linked with Currency. Easiness/Clarity is similar to Accuracy. Overall, information users and professionals function with a similar social collective of shared meanings for the concept of relevance. The overall findings identify the core and periphery concepts of relevance and their relationships in terms of coreness, similarity, and weighted frequency.

Objectives : This paper summarizes results from review of 36 cases and medical records extracted from Yeoksimanpil, involving treatment of exogenous disease in the last Joseon dynasty, and considers significance of treatment protocols. Methods : About 130 medical records from Yeoksimanpil related to exogenous disease were reviewed, and 36 cases were extracted for closer investigation. The author examined the characteristics of exogenous diseases treated in Yeoksimanpil during the Joseon dynasty, employing Yi Suki's theory about exogenous febrile disease, and analyzed the theory from the viewpoint of epidemic febrile disease (溫病學). Results : The majority of exogenous diseases recorded in Yeoksimanpil include Sanghan (傷寒); Seo (暑); Ryeohwan (厲患); and Hongjin (紅疹). Sanghan was found to be prevalent among the exogenous diseases, but diseases caused by warmth and epidemic are recognized separately from Sanghan. Yi Suki's theory about exogenous febrile disease is similar to the basic theory of modern epidemic febrile disease, although his theory was developed independently during the last Joseon dynasty. Conclusions : Although some exogenous diseases in Yeoksimanpil were recognized separately, Yi Suki did not specify each feature nor did he focus on each symptom. Instead, the author's research suggests that Yi Suki was able to identify and treat a variety of various exogenous diseases due to his accumulation of medical knowledge and skill.

The purposes of this study were to examine the two processes of social comparison and self-comparison, and to suggest the applications of social comparison theories and self-comparison theories. For these purposes, social comparison theory, self-evaluation maintenance model, control theory, self-discrepancy theory, regulatory focus theory, and temporal comparison theory were reviewed. The processes of social comparison and self-comparison are different, but both comparisons are similar in that they have some effects on self-evaluation, emotion, motivation and behaviors. Suggestions on education, health, economic justice and interpersonal relationships were discussed.

Objectives : This study was performed to investigate the effect of root extract of Pueraria thunbergiana Bentham (Puerariae Radix, PR) in diabetic mice as similar as emaciation-thirst disease in Oriental medicine. Methods : C57BL/6 mice were fed high fat (HF) and high sucrose (HS) for 8 weeks, and then administrated with 90 mg/kg body weight (bw) of streptozotocin (STZ) for induction of diabetes which is similar to the middle emaciation stage. After 5 days, blood glucose levels were measured, and selected the mice with ranges above $250mg/d{\ell}$. PR water extract was administrated orally once a day for 4 weeks with high fat and high sucrose. The levels of glucose, insulin, total cholesterol, triglyceride, ${\gamma}glutamyl$ transpeptidase (${\gamma}GTP$), glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analysed in the serum. Also, observed their histological changes by hematoxylin and eosin (H&E) of different organs, lung, heart, pancreas, stomach, liver, and kidney. Results : PR extract significantly decreased the levels of serum glucose and insulin in diabetic mice. PR extract significantly increased the levels of triglyceride, total cholesterol, GOT and GPT in diabetic mice. In H&E stain, PR extract inhibited the histopathological changes of lung (as a channel of the upper emaciation stage in the channel-tropism theory), pancreas (as a channel of the middle emaciation stage) and kidney (as a channel of the lower emaciation stage) in diabetic damage. Conclusions : PR extract has an anti-diabetic effect in HF/HS and low-dose STZ-induced diabetic mice. This result suggests that PR follows the channel-tropism theory in the emaciation-thirst disease through the protection of lung, pancreas and kidney.
