Since 2017, the application of VR technology in the game field has become more and more extensive, and more and more scholars have conducted research on VR games, especially VR horror games. This article will conduct research on VR horror games and scrolling scroll games through comparative analysis, and believes that VR horror games are much stronger than side scrolling scrolling games in terms of immersion. However, due to its unique flat third-person perspective, completely different operation methods and the existence of 'the fourth wall in side-scrolling horror games, Players can clearly realize that they are in an absolutely safe environment, and that they are just manipulators of game characters, not experiencers of terrorist events, so players will not receive excessive fright. Therefore, this article believes that the number of players who like side-scrolling horror games with certain horror elements is greater than the number of players who like pure VR horror games.Many traditional games in this paper have their own advantages in many aspects. For example, many traditional games such as horizontal games also have good development prospects in the future. We should promote the research on games in the academic community from multiple angles, not limited to popular VR games.

Purpose: The purpose of the study was to explore how hospital nurses decide to quit working as professional nurses using the grounded theory method. Method: The data was collected by individual in-depth interviews with 12 hospital nurses who recently resigned from work and it was analyzed using 'constant comparative analysis.' Result: The core category that emerged was "in search of new balance with self, work, and family". Three stages were identified: 1) "unconditionally accepting the working situation of itself," 2) "weighing advantages and disadvantages of working as a hospital nurse", and 3) "redesigning a future". Each stage contains three major strategies. The major strategies of the first stage are "maintaining a learning attitude", "enduring physical burnout," and "enduring unfair interpersonal relationships". The second stage contains "identifying advantages of working", "identifying disadvantages of working", and "comparing the advantages with the disadvantages". Lastly, the third stage includes "reassessing the aim of life", "beginning to construct an alternative life", and "deciding to quit working at a certain point". Conclusion: The results of the study will help nursing administrators in designing and implementing an effective turnover prevention program for nurses by understanding more deeply the process of turnover phenomenon among hospital nurses.

Due to the decrease in coastal productivity and deterioration in the quality of ecosystem which result from the excessive overfishing of fisheries resources and the environmental pollution, fisheries resources in the Korean waters hit the dangerous level in respect of quantity and quality. In order to manage sustainable and effective fisheries resources, it is necessary to suggest the potential yield (PY) for clarifying available fisheries resources in the Korean waters. So far, however, there have been few studies on the estimation methods for PY in Korea. In addition, there have been no studies on the comparative analysis of the estimation methods and the substantial estimation methods for PY targeted for large marine ecosystem (LME) For the reasonable management of fisheries resources, it is necessary to conduct a comprehensive study on the estimation methods for the PY which combines population dynamics and ecosystem dynamics. To reflect the research need, this study conducts a comparative analysis of estimation methods for the PY in the Korean waters of the East Sea to understand the advantages and disadvantages of each method, and suggests the estimation method which considered both population dynamics and ecosystem dynamics to supplement shortcomings of each method. In this study, the maximum entropy (ME) model of the holistic production method (HPM) is considered to be the most reasonable estimation method due to the high reliability of the estimated parameters. The results of this study are expected to be used as significant basic data to provide indicators and reference points for sustainable and reasonable management of fisheries resources.

In order to measure the absolute plasma density, various probes are proposed and investigated and microwave probes are widely used for its advantages (Insensitivity to thin non-conducting material deposited by processing plasmas, High reliability, Simple process for determination of plasma density, no complicate assumptions and so forth). There are representative microwave probes such as the cutoff probe, the hairpin probe, the impedance probe, the absorption probe and the plasma transmission probe. These probes utilize the microwave interactions with the plasma-sheath and inserted structure (probe), but frequency range used by each probe and specific mechanisms for determining the plasma density for each probe are different. In the recent studies, behaviors of each microwave probe with respect to the plasma parameters of the plasma density, the pressure (the collision frequency), and the sheath width is abundant and reasonably investigated, whereas relative diagnostic characteristics of the probes by a comparative study is insufficient in spite of importance for comprehensive applications of the probes. However, experimental comparative study suffers from spatially different plasma characteristics in the same discharge chamber, a low-reproducibility of ignited plasma for an uncertainty in external discharge parameters (the power, the pressure, the flow rate and so forth), impossibility of independently control of the density, the pressure, and the sheath width as well as expensive and complicate experimental setup. In this paper, various microwave probes are simulated by finite-different time-domain simulation and the error between the input plasma density in FDTD simulations and the measured that by the unique microwave spectrums of each probe is obtained under possible conditions of plasma density, pressure, and sheath width for general low-temperature plasmas. This result shows that the each probe has an optimum applicable plasma condition and reliability of plasma density measurement using the microwave probes can be improved by the complementary use of each probe.

The purpose of this paper is to perform empirical studies on the impact of pollution intensity on international competitiveness using 1993 and 1998 data, and to estimate the change in environmental regulation level faced by the firms during 1993~1998. Collecting relevant data and providing them for further studies in the area are another purposes of the paper. The first method is the regression of various indices of international competitiveness on factor costs, such as labor, capital, R&D and pollution abatement costs. Goal of the regression analysis is to estimate the scarcity and comparative advantage effect of each production factor, especially environmental resource. Regression results show that those industries which employ more environmental resource have higher comparative advantage in both years, which implies that Korean firms are endowed with abundant environmental resource compared to other countries. The second method is to compute the relative scarcity indices(HOVL indices) of production factors, proposed by Leamer based on Vanek's generalized Hecksher-Ohlin Theorem. This method estimates the relative scarcity of production factors by computing factor costs embodied in import and export of commodities. This method shows similar results as the regression method; i.e., trade pattern of production factors implies that the manufacturing sector in Korea is endowed with abundant environmental resource compared to other countries. Considering population density, water resource endowment, intensity of economic activity per unit area and current air and water pollution levels, it is evident that Korea is never endowed with abundant environmental resource compared to other countries. Then the abundance of environmental resource revealed by the trade patterns of commodities and production factors implies that Korea's environmental regulation level is excessively generous compared to environmental capacity, and that this increased the environmental resource endowment supplied to firms and thus distorted the inter-industry comparative advantages. Both regression and HOVL methods, on the other hand, show that overall environmental regulation level faced by the firms has been strengthened during 1993~1998.

This study aims at comparing and analyzing early childhood education systems in both South and North Koreas and suggesting educational alternatives for integrating in various aspects based on it, in order to build directions of early childhood education system in the preparation of Unification. A comparative study on the early childhood education system in South and North Korea was done in terms of early childhood education, public education of early childhood. As a result, there were differences rather than similarities in many areas due to the differences of political ideology between the South and the North. First, early childhood is not compulsory, but becomes public in South, while it is partially compulsory and has an overall public system in North in terms of its compulsory education and Pulic education. Second, as a result of comparing operating systems depending on early childhood education institutions in the South and North, there were differences in various areas such as subjects of foundation, classification of age, operating types, etc. Third, looking at its administrative support system, two Koreas has a similarity of a overall dual system, but showed a specific difference. Fourth, its public support had a similarity that early childhood education is done free of charge in two Koreas. In light of the results of comparing the early childhood education system in South and North Korea, this study suggests the following implications. First, as part of an effort to restore similarities of the early childhood education system between two Koreas, a challenge that must be addressed with priority is to integrate early childhood education-nursery in the early childhood education for age 3-5. Second, we'll take an effort to include the early childhood education for age 3-5 in the basic disciplines with 'Making early childhood education public' being currently focused. In addition, we should an attitude to recover a similarity through mutual exchange and to have advantages of the early childhood education in two Koreas as a challenge of taking an effort to integrate the early childhood education in the South and the North various studies and debates, discussions will be made for the meaning of the early childhood education and the integration.

A comparative study was performed to evaluate the signal amplification strategies in electrochemical affinity sensing, which included the direct electron transfer and diffusible-group mediated electron transfer between label enzymes that were specifically bound to target proteins and chemically modified electrode surfaces. As a platform surface for affinity recognition reactions, a double functionalized poly(amidoamine) dendrimer monolayer that was modified with ferrocene and biotin groups was constructed on a gold surface. With the chemically modified electrode, a model affinity sensing with avidin was investigated. The advantages of adopting the diffusible-group mediated signaling strategy were demonstrated in terms of signal sensitivity and stability.

Multiple-input multiple-output (MIMO) multiplexing is an attractive technology that increases the channel capacity without requiring additional spectral resources. The design of low complexity and high performance detection algorithms capable of accurately demultiplexing the transmitted signals is challenging. In this technical survey, we introduce the state-of-the-art MIMO detection techniques. These techniques are divided into three categories, viz. linear detection (LD), decision-feedback detection (DFD), and tree-search detection (TSD). Also, we introduce the lattice basis reduction techniques that obtain a more orthogonal channel matrix over which the detection is done. Detailed discussions on the advantages and drawbacks of each detection algorithm are also introduced. Furthermore, several recent author contributions related to MIMO detection are revisited throughout this survey.
