The purpose of this study was to compare and review the effects of demographic and social characteristics, regional characteristics, economic characteristics, and relational characteristics on real estate rental income for profits by classifying middle and old age. In particular, the Hausman test was used to determine which model is more suitable between the fixed-effect model and the random-effect model, and a subdivided model by comparing the overall model and the subdivided model by age using the random-effect model as a suitable model. We wanted to see what the difference is. As a result of the analysis, comparing the middle and old ages, first, in the middle age, it is a time when the cost is high, and it is a time to prepare a living space. There is a shortage of capital to buy real estate for profits that can greatly generate money. Second, in the case of old age, it is a time when income decreases from the total amount of debt to retirement, and because the ability to deal with debt decreases because of the need to prepare for retirement for old age, the rent for profitable real estate will decrease or be sold. will be. Third, in the case of middle-aged people, if the social friendship improves, the information for generating profit is obtained, so it is judged to increase the rental income of real estate for profit. Fourth, in the case of mature socio-economic status, it was found that the upper class share information, so it has a positive effect on the rental income of profitable real estate.

There is a little information on the effect of calcium cloride (CaCl2) which is used as deicing salt in Korea on the physiological responses of the street trees. Prunus sargentii is one of the most widespread tree species of street vegetation in Korea. In this study, the effect of CaCl2 on photosynthetic apparatus such as chlorophyll fluorescence image and light response curve of P. sargentii in relation to their leaf and root collar growth responses were investigated. To study the effect of CaCl2 treatment in the early spring, we irrigated twice in rhizosphere of P. sargentii (3-year-old) planted plastic pots with solution of 0.5%, 1.0%, 3.0% CaCl2 concentration before leaf expansion. Results after treatments, total chlorophyll contents and the chlorophyll a/b, photosynthetic rate, quantum yield, dark respiration decreased with increasing CaCl2 concentration. On the contrary, light compensation point increased with increasing CaCl2 concentration. Through the linear regressions of correlation of photosynthetic rate with photosynthetic parameters (quantum yield, dark respiration and light compensation point), we found a significant relationship (p<0.05) between photosynthetic rate and quantum yield and light compensation point except dark respiration. Calcium cloride (CaCl2) induced inhibition of photochemical efficiency (FV/FM) and non-photochemical quenching (NPQ) were found in treatments of CaCl2, and these reduction rates between control and CaCl2 treatments were drastically showed at 80 days. We suggest that physiological activities are limited from treatment of CaCl2. These reductions of photosynthetic apparatus ability caused eventually the reduction of leaf and diameter at root collar growth.

성주한(Sung, Joo-Han) 한국부동산정책학회 2020 不動産政策硏究 Vol.21 No.2

The purpose of this study is to influence the chonsei price of an apartment in Changwon City through the core contents of the Changwon City housing market, such as the apartment chonsei price in Changwon City, the apartment sale price in Changwon City, the corporate bond yield (interest rate), the number of population in Changwon City, the housing construction permit in Changwon City, and the volume of apartment transactions in Changwon City. I would like to study and see what factors have the greatest influence. Before 2016, the variable that had the greatest influence on the change rate of chonsei price in Changwon city (GCHACHONSEI) was the rate of change in sales price of apartment in Changwon (GCHASALE), which was found to have a positive effect. And it was found that the change rate of the Changwon housing construction permit (GCHAHC) had a negative (-) effect. The next order was the change rate of unsold apartments in Changwon (GCHUNSOLD), which was found to have a negative (-) effect. In the following order, it was found to have a positive (+) effect as the Changwon Population Change Rate (GCHPOP). On the other hand, after 2016, the variable that has the greatest influence on the change rate of chonsei price in Changwon city (GCHACHONSEI) is the rate of change in the sale price of apartment in Changwon (GCHASALE), which was found to have a positive effect. The next order was the change rate of unsold apartments in Changwon (GCHUNSOLD), which was found to have a negative (-) effect. The next order was the Changwon Population Change Rate (GCHPOP), which was found to have a positive (+) effect. Before 2016, unlike other variables, there was no significant influence, but the continued decrease in the population change rate in Changwon City after 2016 is believed to have lowered the rate of change in apartment jeonse prices in Changwon.

The purpose of this study is to analyze the impact on unsold apartments in Changwon City before and after structural changes, and to examine the difference between the two periods. Through these differences, I would like to add policy suggestions for the management of unsold sales in Changwon City. The effect of this study on unsold apartments in Changwon before and after 2016 is as follows. Prior to 2016, the variable that had the greatest influence on the unsold apartments in Changwon city was the change rate of housing construction permit in Changwon City (GCHAHC), followed by the rate of change in the apartment chonsei price in Changwon City (GCHASCHONSEI). The change rate of housing construction permit in Changwon (GCHHC) has a negative (-) effect, and the performance of housing construction permit in Changwon was concentrated from 2011 to 2013. For this reason, even though there are many Changwon housing construction permit, it was found to have had a negative (-) effect because unsold sales in Changwon were reduced because all of them were satisfied by demand. In addition, the rate of change in apartment chonsei prices (GCHACHONSEI) in Changwon has a negative (-) effect. As the chonsei price rises and the sale price rises, the unsold apartments decreased even if the supply volume increased. Since 2016, the variable that has the greatest influence on the unsold apartments in Changwon City is the change rate of housing construction permits (GCHAHC) in Changwon City, followed by the rate of return on corporate bonds (GCPR). The change rate of housing construction permits of Changwon-si(GCHHC) has a negative (-) effect. Since 2016, demand has declined due to the stagnation of the Changwon city s economy, and the unsold apartments in Changwon city increased because the supply of housing construction completed in Changwon before 2016 continued to stagnate after 2 years and 6 months to 3 years. In addition, the corporate bond yield (GCPR) has a negative (-) effect, and the decline in interest rates was found to increase unsold sales in Changwon. It was found that the decline in interest rates increased the housing price, which increased the performance of the housing construction license in Changwon, thereby increasing unsold sales in Changwon.

본 연구의 목적은 서울과 지방 등 지역에 따라 부동산가격이 다르게 움직이고 있는 상황에서 정부가 부동산 가격정책을 어떻게 적용할 것인지에 대해 살펴보고자 한 것이다. 특히, 시도별과 지 역별로 만들어진 패널데이터를 가지고 아파트 매매가격에 영향을 주는 요인들이 어떤 것인지를 살펴보고자 한다. 본 연구결과를 요약하면 다음과 같다. 고정효과모형의 결과로, 아파트전세가격과 인구수의 증가는 아파트매매가격을 상승시킨 것으로 파악되었고, 금리(회사채수익률)의 상승과 아파트 주택인허가실적과 미분양의 증가, 실업률이 높은 경우에는 아파트 매매가격을 하락시킨 것으로 나타났다. 또한 시간특성에서 2011년을 기준변수로 볼 때, 2013년부터 2018년까지 계속 아파트매매가격이 증가한 것으로 파악되었다. 1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to examine how the government will apply the real estate price policy in a situation where real estate prices are moving differently depending on the regions such as Seoul and the provinces. (2) RESEARCH METHOD This study employed the fixed effect model to achieve the major objectives of this study. (3) RESEARCH FINDINGS The implication of this study is that it shows that there is meaning to apply differentiated policy between Seoul and Gyeongnam through the housing market of Seoul and Gyeongnam which are the most opposite and show the current situation of other housing prices. 2. RESULTS We will examine the factors affecting the sale price of apartments with panel data made by provinces and regions. The results of this study are summarized as follows. As a result of the fixed effect model, it was found that apartment rent price and population ncrease led to an increase in the apartment sale price, and when the interest rate (corporate bond yield) rises, the apartment house licensing result and the unsold housing are increased and the unemployment rate is high. In terms of time characteristics, when the year 2011 is taken as a reference variable, it is concluded that the selling price of apartments continued to increase from 2013 to 2018.

This study was conducted to estimate the changes of stand diversity before and after applying threedifferent silvicultural treatments such as selection cutting system, two-storied system, and shelterwood system. Data were collected in the natural deciduous forests in Pyungchang of Gangwon Province, Korea. Ninepermanent sampling plots of 0.09 ha were established in the forests and the each of silvicultural treatments wasapplied to three sampling plots, respectively. Some tree variables were measured in each stand before and afterthe silvicultural treatments were applied. With these data, stand attributes were estimated in each stand beforeand after the silvicultural treatments. In this study, two different indices related to each of stand diversity indicessuch as contagion, DBH-difference, height-difference, and mingling were estimated and compared to analyze thedifferences of stand diversity among the stands before and after silvicultural treatments. As a result, total eightstand diversity indices were used to analyze the differences among structures of stands managed by three differentsilvicultural treatments. Duncan``s multiple range test and t-test were then employed to statistically analyze thedifference of stand diversity among the stands. The results revealed that stand structures seem to be improved afterapplying the silvicultural treatments. There are significant differences in the stand diversity indices between beforeand after silvicultural treatments for each stand. According to the evaluation of stand diversity indices, it wasconfirmed that spatial structure of the stands was improved by applying the silvicultural treatments.

This study was conducted to provide a method of establishing two-storied forests by the adjustment of stand structures in natural deciduous forests of Pyeongchang area. Three permanent sampling plots of 0.09 ha were established in study site and some tree variables were measured in each sampling plot before the treatment of two-storied system. Stand attributes and stand structures before treatment were estimated based on the data measured in sampling plots. The results indicate that the current stand status is different from typical stand structures of two-storied forests. A simulation technique was applied to predict stand attributes and stand structures after the treatment of two-storied system. Results suggest that significant time is required to accomplish target stand structures even after applying the treatment of two-storied system. Number of trees in the upper canopy class after treatment was predicted to be 170 trees/ha, which adequately meets the target of two-storied forests. It was predicted, however, that the lower canopy class trees has much less trees compared with the typical stand structures of two-storied forests. This problem could be solved with ingrowth of infant trees over time or by under-planting of tolerant species. It is confirmed that the target growing stock volumes of the upper canopy class should be approximately 150 m3/ha considering stand status after treatment. It is predicted that twenty years of conversion period is required to accomplish this goal. The changes in stand structures over time should be assessed based on stand inventory carried out every five years, and additional treatments for inducing two-storied forests should be applied if necessary.
