In order to evaluate soil factors affecting the growth of Italian poplar, 23 areas planted with Italian poplar were surveyed. These 23 areas were classified into 3 categories, river-side, fallow-land and hill-side. The growth performance and soil factors for each area were investigated. The growth of Italian poplar at river-side was shown to be superior to that of fallow-land and fill-side. The rates of growth for fallow-land and hill-side are decreased by 8% and 21% compared to those of river-side, respectively. This suggests that plantation of Italian poplar at hill-side would not be profitable. Soil conditions of high productive area appeared liquid phase 20%, porosity 45%, water holding capacity 35 - 40%, soil hardness $1kg/cm^3$. pH 6 and rich in organic matter and total nitrogen. The results of factor analysis for soil factors affecting to Italian poplar growth that showed eigenvalue over 1 and communality value over 70% explained factor 1 : liquid phase, porosity and water holding capacity, factor 2 : pH and calcium, and factor 3 : soil hardness. This suggests that physical characteristics of soil is more important than chemical characteristics for Italian poplar growth. Multiregerssion analysis was conducted between diameter growth and soil hardness, liquid phase and calcium. The t-values for each independent variables showed significance at 1 - 10% level, but water holding capacity and pH are not significant. It is supposed that sites suitable to Italian poplar were alluvial plain of sandy loam or part of banking soil, well-ventilating soil, lower soil hardness, apposite soil moisture absorbing with about 100cm of ground water level, plentiful organic matters and total nitrogen and little acidity soil.
The purpose of this paper is to analyse the locations and to interpret the landscapes of the local towns in Joseon Dynasty from Feng-shui's point of view. As a result of analysing the locations of towns in Gyeongsang Province, the towns which have typical Feng-shui landscapes make up to 58% of the total. Historically, the local towns that were established in the early period of the Joseon Dynasty didn't reveal Feng-shui's landscape, but those that were established in the late period of the Joseon Dynasty revealed the Feng-shui's landscape clearly. In this article, I classify the local towns of the Gyeongsang Province into 3 types: 1. Non Feng-shui type These towns are located near the seashore. The main reason that these towns were located at the seashore was defense against an enemy. 2. Semi Feng-shui type. These towns don't have natural location but have a man-made landscape, based on the principles of Feng-shui. 3. Typical Feng-shui type. These towns were typically administrational towns which were located at the center of a local region.

This study adopts an ecological perspective to empirically navigate the issues surrounding the impact of parental abuse on the emotional development of adolescents. The data is used from the Korean Children and Youth Panel Survey 2011 (KCYPS 2011), which was conducted by the National Youth Policy Institute (n=2,270). Path models were constructed in which adolescents' environmental mediators (i.e., the relationship with parents, friends, and teachers; and school life) control their negative emotions (i.e., aggressiveness, negative physical symptoms, social weakness and depression); in turn to compare the difference between two groups based on parental abuse by using Structural Equation Modeling (SEM). As with the non-abused group (n=1,644), all the environmental mediators remained significant to control their negative emotion; whereas, the abused group (n=626) showed no significant pathway from their relationship with teachers and school life to negative emotion. This indicates that the abused group have limited number of the mediators to control their negative emotion than those of the non-abused group. For the non-abused group, the mediator with the highest total effect to control their negative emotion was the relationship with their friends; on the other hand, the abused group's mediator that showed the highest total effect to control their negative emotion was the relationship with their parents. Although the relationship with teachers remained significant as a mediator to affect school life for the both groups, teachers were not significant to control the negative emotion of the abused group. These findings suggest that the negative relationship with teachers in the abused group is a factor to threat the school adaptation of adolescents, which also leads to problems that are related to the emotional development of adolescents.
To examine the relationship between environmental factors influencing the habitat of Aconitum austrokoreense Koidz., this study employed the MexEnt model to evaluate 21 environmental factors. Fourteen environmental factors having an AUC of at least 0.6 were found to be the age of stand, growing stock, altitude, topography, topographic wetness index, solar radiation, soil texture, mean temperature in January, mean temperature in April, mean annual temperature, mean rainfall in January, mean rainfall in August, and mean annual rainfall. Based on the response curves of the 14 descriptive factors, Aconitum austrokoreense Koidz. on the Baekun Mountain were deemed more suitable for sites at an altitude of 600 m or lower, and habitats were not significantly affected by the inclination angle. The preferred conditions were high stand density, sites close to valleys, and distribution in the northwestern direction. Under the five-age class system, the species were more likely to be observed for lower classes. The preferred solar radiation in this study was 1.2 MJ/m2. The species were less likely to be observed when the topographic wetness index fell below the reference value of 4.5, and were more likely observed above 7.5 (reference of threshold). Soil analysis showed that Aconitum austrokoreense Koidz. was more likely to thrive in sandy loam than clay. Suitable conditions were a mean January temperature of - 4.4℃ to -2.5℃, mean April temperature of 8.8℃-10.0℃, and mean annual temperature of 9.6℃-11.0℃. Aconitum austrokoreense Koidz. was first observed in sites with a mean annual rainfall of 1,670- 1,720 mm, and a mean August rainfall of at least 350 mm. Therefore, sites with increasing rainfall of up to 390 mm were preferred. The area of potential habitats having distributive significance of 75% or higher was 202 ha, or 1.8% of the area covered in this study.
Companies have recently become increasingly interested in corporate entrepreneurship to establish a core employment policy in order to secure and maintain core employees and to foster an innovation-oriented organizational culture. Therefore, The purpose of this study is to empirically analyze the causal relationship between core employment policies and the team leader's the perceived internal process organizational competency and job satisfaction, and to investigate whether corporate entrepreneurship has a moderation effect. Non-financial service industries including ICT companies were subject of the study and human capital corporate panel(HCCP) was utilized. The samples were 367 team leaders from 79 domestic companies. This study also applied Multi-Level Analysis(HLM), which simultaneously analyzes variables at both the individual level and the organizational level in order to improve the accuracy of the study. According to the result of the study analysis, core employment policies have a positive(+) impact on the perceived internal process organizational competency and job satisfaction. In addition, the moderation effect of corporate entrepreneurship was verified during the process when core employment policies influence the two outcome variables. corporate entrepreneurship was found to have a moderation effect that strengthens the influence on job satisfaction, but the moderation effect on the perceived internal process organizational competency was not statistically significant. These results confirm that organizational cultural factors such as corporate entrepreneurship are important influence variables in the process of influencing individual-level variables such as core employment policies. Academically, It suggests that in order to enhance the effectiveness of company strategies in respect of human resource management such as core employment policies, it is important to foster a cultural environment that suits the industry and characteristics of the organization. In addition, it suggested that companies in need of new innovation need to utilize corporate entrepreneurship.
This research aims to suggest a practical solution in order to make marriage immigrant women free from violence and stand on their own. The suggestion could be made by developing Substantive theory in terms of marriage immigrant women's coping with domestic violence. The research question is; How marriage immigrant women cope with domestic violence. The research used a route theory approach, and 11 of marriage immigrant women who have ever suffered from domestic violence participated in it. The research question used semi-structured open questions. As a result of paradigm model analysis, "mental and physical devastation" is defined as a core phenomenon, and causative conditions are "wheel of pain" and "helpless victims of violence". Besides, context conditions are "period growth with solitariness", "irrational marriage" and "indifferent reality". "Mental and physical devastation", the core phenomenon act and interact with effect of mediatory conditions; which are "social help", "cultural difference" and "helplessness". Here the action and reaction appear as "adaptation", "resistance", "self-protection" and "self-reinforcement", and the outcomes show up as "maintaining reality", "decision making" and "beginning a new life". "Coping with mental and physical devastation and standing on one's own feet" could be introduced as a core category. Process of coping with domestic violence presents its levels as; shocks ${\rightarrow}$ endurance ${\rightarrow}$ regret ${\rightarrow}$ overcoming. There are three patterns of coping, which are; "preserving realities", "returning", and "groping for the future".
In this study, we explored Technology Acceptance Model(TAM) to introduce Blockchain technology in the medical field. It extracted five external variables(Security, Availability, Reliability, Diversity, Economic feasibility) through previous studies. It set the study model for a path to acceptance intention through the information reliance of recognized easiness and recognized usefulness. As results of empirical analysis, H1-1(Security →Perceived Easiness) was rejected. H1-2(Availability→Perceived Easiness), H1-3(Reliabilit→Perceived Easiness), H1-4(Diversity →Perceived Easiness), H1-5(Economic →Perceived Easiness) were adopted. Hypothesis 2 was a relations between Blockchain's characteristics and Perceived usefulness, all the Hypothesis were adopted. Hypothesis 3 and Hypothesis 4 indicated that H3-1(Perceived Easiness →Perceived usefulness) was rejected but H3-2(Perceived Easiness → information reliability), H3-3(Perceived usefulness → information reliability), and H4(information reliability→acceptance intention) were all adopted. It was confirmed that it is important to emphasize the importance of stability to introduce block chain technology to medical centers, but it was necessary to use a design that can increase the easiness from the prospect of users.
As the interest and use of computer have been increased among elderly users according to the entry to the aging society, the issue of universal design for computer usability was brought forward. Especially, it is widely recognized that universal UI(User Interlace) design on MS windows is important. The objective of this study is to conceptualize Universal GUI design on MS windows which can be used more easily and intuitively by novice users such as elderly and housewives. Especially, the solution for Universal GUI design on MS windows was developed by reflecting elderly users' needs because elderly users is the group with more difficulties than other user groups in learning and using MS windows. First, elderly user's needs was collected by participant observation as a teaching assistant in computer dass for elderly people for 4 weeks. Secondly, the experimental test and in-depth interview was implemented to find difficulties factors and needs in addition to participant observation. Based on the findings, the new GUI design solution was suggested. The design solution consists of ideas in several categories such as setting default, simplification of function for easy conceptual model making, customization of function and working environment, and intuitive GUI in interaction process. The new MS windows GUI design can be accessed by novice mode when user login in window XP. This study has the significance in finding elderly users detailed needs through in-depth and long term participant observation. However, the usability of the suggested prototype needs to be verified to various user groups besides elderly users in the future.

In this paper, we proposed a forest fires prediction and detection system. It could provide a situation of fire prediction and detection methods using context awareness sensor. A fire occurs wide range of sensing a fire in a single camera sensor, it is difficult to detect the occurrence of a fire. In this paper, we propose an algorithm for real-time by using a temperature sensor, humidity, Co2, the flame presence information acquired and comparing the data based on multiple conditions, analyze and determine the weighting according to fire in complex situations. In addition, it is possible to differential management of intensive fire detection and prediction for required dividing the state of fire zone. Therefore we propose an algorithm to determine the prediction and detection from the fire parameters as an temperature, humidity, Co2 and the flame in real-time by using a context awareness sensor and also suggest algorithm that provide the path of fire diffusion and service the secure safety zone prediction.
The study attempted to use computed tomography images to determine the usefulness of the reduction in the axial reduction algorithm in the event of a metallic artifacts reduction in the image of the beam-hardening effect, which is known as the most effective method of reducing metallic artifact reduction in the image and the reduction of the metal produced in this study. As a result, the result is increased to 140 kVp to reduce the value of the CT value by 0.02 to 0.05 %, resulting in decreased axial effect (P > 0.05). The CT value decreased from 12.4 to 26.9 % when applied to the reduction of the metallic. 12.4 to 26.9 % (p<0.05). In addition, in the qualitative assessment by the clinical trial evaluation, it was assessed as 1.8 points after applying the MAR algorithm, In the resolution of resolution and contrast evaluations, the estimation of the decrease in metallic artifact effects was assessed as the metal was assessed to be scored 7.2 points after the MAR algorithm was evaluated. Therefore, in case of artifacts due to irreversible beam hardening effect, it is useful to reduce artifacts caused by beam hardening effect by using various methods derived from existing researches and scanning by applying the metal artifact reduction algorithm proposed in this experiment.
