  • Forest inventory is a commercial term meaning the preparation of detailed descriptive list of articles with number, quantity and value of each item included. Forest inventory deals with the measurement of trees and stands, the estimation of their volume, growth prediction, biomass, carbon stocks and the description tree characteristics, as well as the land upon which they are growing. National Forest Inventory Center (NFIC) in Korea conducts national forest inventory every 5 years to obtain accurate baseline data for national forest policy. The permanent sample plot data used in were collected by NFI. The objective of this study was to develop methods for quantifying forest resources at national scale based on $5^{th}$ National Forest Inventory (NFI) data in Korea. Forest land area decreased from 6.44 to 6.38 million ha between 1997 and 2007, continuing a slight downward trend in area beginning in the late 1990s. However forest resources of the Korea have continued improving in general condition and quality, as measured by increased average size and volume of trees. Growing-stock volume of the Korea increased from 17 to 123.79 cubic meter per ha between 1976 and 2007. The biomass in Korea was estimated to be 153.81 tons per hectare and carbon stocks in Korea was estimated to be 84.36 tons per hectare by NFI data. This information is important for government officials, public administration, the private business sector, and the researcher. Forest Inventory should be implemented in a way to be able to monitor and assess the forests continuously.

  • In-app advertisement is a fast-growing trend in mobile advertising, where user acceptance of ads is facilitated by the fact that users have voluntarily downloaded the app through which the ad is served. However, research in this ad category is limited. This study applies an extended version of the theory of planned behavior. Analysis results from 412 young mobile users in Vietnam using structural equation modeling showed that while localization and perceived enjoyment affected user intention to watch in-app ads as expected, perceived behavioral control and trust did not. Such results may be due to embedding the ads to applications, confusing users' behavioral intentions. The results underline the need for more future research in the area. In practical terms, companies should improve localization and entertainment aspects of ads to create more relevant and engaging advertisements.

  • Apartments have been the most prevalent type of housing in Korea for the past few decades. During those times, apartments have emerged as one of the most attractive real estate properties in Korea, with the still growing population living in them. Now that over twenty years have passed since the 1970s and 1980s when apartment construction started booming, building stocks are increasing that need refurbishment. In this concern, apartment extension has raised public interest for the past few years, as the remodeling of them has mainly been considered in terms of increasing asset value in Korea. It comes through in our study that these extension types are examined by such items as building core types, number of rooms and front and rear bays in unit, and other design features related to extension techniques. The objective of this study is to suggest a way to produce the best quality possible of unit plan through extension.

  • The Korean apparel manufacturing industry started to meet domestic demands which had depended on importation in 1950s, growing into one of the export-oriented industries with several Five-Year Economic Development Plans. In spite of the development, inefficient organization of distribution of apparel manufacturing industry which connects production with consumption impedes further development of the industry. This study aims at suggesting desirable distribution system of ladies' apparel, the core of the fashion industry. This researcher interviewed those who are concerned in twenty-eight ladies' apparel manufacturing compaines, analyzing the current state of distribution in the industry and the problems. The results are as follows; 1. Forty-five percent of ladies' apparel is distributed through department stores. Therefore, the department stores need to assume their roles in sales and try to improve the condition and to train professional buyers. 2. The sales network is concentrated on the five biggest cities such as Seoul, Pusan, Taegu, Taechon, and Kwangju, prompting the need to be diversified. 3, Tke existing distribution forms distribution systems have many irrational factors which are aggravnting the rate of goods in stock. 4. The manufacturing companies do not implement studies on distribution. The companies should try to establish clear concepts on production and distribution on their own for better planning skills. 5. Computerized systems need to manage the procedures ranging from ordering, distribution, sales to inventory.

  • A population segregating for the naked neck (Na) gene was used to evaluate its effect on fast growing broilers at heat stress. An experimental stock comparable to those of modern broilers was established by backcrossing to colour synthetic male and female lines. Matings between heterozygous (Na/na) males and females produced normally feathered (na/na), heterozygous (Na/na) and homozygous (Na/Na) chicks for the present study. Day old to seven week old coloured broilers of three genotypes viz. normally feathered (na/na), heterozygous naked neck (Na/na) and homozygous naked neck (Na/Na) were compared for heat dissipation, growth performance, body conformation traits, blood biochemical parameters and carcass traits in tropical climate. In hot climate, naked neck broilers had significantly less body temperature and better heat dissipation capabilities as compared to normal broilers. The naked neck broilers had significantly higher body weight and better feed conversion ratio than na/na broilers. The Na/Na or Na/na broilers exhibited higher giblet yield, blood loss and lower feather mass compared to na/na broilers. The results indicated that the reduction in feather coverage in Na/Na and Na/na broilers facilitates better heat dissipation with lower body temperature, more body weight gain, better FCR and carcass traits compared to normal broilers.

  • This article addresses issues related to environmental pollution.Particular attention is paid to the prevention of environmental pollution by livestock waste, which prompted the creation of closed ecological and biotechnical systems as environmentally closed production structures that can fit into the equilibrium system of the environment with minimal damage to it. An energy-saving and environmental protection technology for the processing and disposal of livestock waste with a maximum coefficient of energy transfer to livestock products has been developed, which consists in a combined treatment of waste in three stages, by transferring waste from one technological module to another, which makes it possible to completely utilize mineral substances in waste. The focus is on vermicultivation, microalgae cultivation and anaerobic fermentation in a bioenergy plant. To increase the productivity of growing microalgae, the authors proposed a deep type cultivator with submerged movable light sources.The technological parameters of the bioenergy installation for waste treatment are determined. An energy-saving and environmental-friendly technology has been developed for processing The main contribution of the study is the development of energy-saving and environmental technology for the processing and disposal of livestock waste with a maximum coefficient of energy transfer to livestock products.

  • The Publicly Purchased Property (PPP) Program since 2004 has allowed low-income households to reside in decent housing at a reasonable expense and to live in a community they choose. With an increasing number of the housing stock, management of the properties becomes a growing concern. The purpose of this research is to find out the satisfaction of the tenants with residential environment and housing management. To collect data, a face-to-face interview survey was conducted for 310 households living in the designated properties of 8 cities in and outside the Seoul Metropolitan Area (SMA). Most of the households were a family of three headed by late middle-aged man and lived in physically sound, small-sized units at an affordable cost. Overall satisfaction with living environment was higher in non-SMA than in SMA, and influenced by building deterioration and unit size. Further, most of the respondents were in favor of housing management services provided by a nearby public housing estate. Building deterioration and regular onsite visits of management staff were determinants in the satisfaction with housing management. The results indicate that proper housing management delays building deterioration and assures decent living for low-income people, leading to high levels of residential satisfaction.
