The purpose of this research is to analyze the wealth effects of home-owning baby-boomers on household consumption on non-durable goods in the Seoul Metropolitan Area. In so doing, this empirical study utilized the Korean Labor and Income Panel Study (KLIPS) of 2002 and 2012. The statistical findings reveal that household wealth in the period had sharply risen in household income, asset, debt and consumption, and the substantial increase came from growing income and consumption embedded into an expansionary stage of the family life cycle. Further, housing wealth had a much greater effect on consumption expenditure than did financial asset in 2012 while financial wealth effect was larger than housing wealth effect in 2002. Housing wealth effects had become far stronger as the age of the baby-boomer householders increased. As the baby-boomers are close to the retirement stage, post-retirement income security becomes of concern, so that the wealth effect of real estate income as an income alternative for retirees is explicit. The results imply that retirement of baby-boomers is likely to reduce consumer spending, aggravating slowdown of the real economy. Thus, diversification of household asset portfolio in a pre-retirement period is of great significance in maintaining adequate household consumption in later life.

Building energy consumption generally depends on living patterns of residents and outdoor air temperature changes. Although outdoor air temperature changes effect on building energy consumption, there is no calibration method for the comparison before and after Green Remodeling or BEMS installation etc., Big data of building energy consumption are collected and managed by 『National Integrated Management System of Building Energy』 in Korea, and they are utilized for the development of a calibration method for individual buildings as shown as the calibration method for small-area building stocks in the previous research. This study aims to develope a calibration method using big data of building energy consumption of individual buildings and outdoor air temperature changes, and to propose application of appropriate calibration methods for individual buildings or small-area building stocks according to the calibration purpose and conditions.

We consider connection-oriented wireless cellular networks such as the second generation wireless cellular networks and wirelss ATM networks. In these networks, a separate forward signaling channel is provided for the transmission of paging and channel allocation packets. When a call destined to a user is requested, all the base stations in the user's current location area broadcast the corresponding paging packet across forward signaling channels. By slot mode operation and paging group allocation for fusers in a location area, we can reduce relative power consumption level at battery-operated terminals. However, a sthe number of paging groups is increased for lowering relative power consumption level, a paging packet experiences higher delay to access the forward signaling channel. For the pre-negotiated quality-of-service level, paging packet delay level must be limited. In this paper, we consider static and dynamic multiplexing schemes for paging packets, and develop an analytical method for calculating paging packet delay and relative power consumption levels. Using this analytial method, we investigate the effect of network parameters on the paging packet delay and relative power consumption levels.

E-commerce is now a familiar form of commercial transaction, especially in the transactions between businesses. This online transaction poses a good deal of problems to the traditional tax system and administration. Realignment of tax system and tax administration in the e-commerce is one of the major topics on the International problem. In the area of consumption tax, they reaffirmed the destination principle. They agreed to decide the recipient's business presence and usual residence as the place of consumption. In the area of consumption tax, they reaffirmed the destination principle. They agreed to decide the recipient's business presence and usual residence as the place of consumption. Currently, the Korean VAT law does not have a basis for taxation on international transactions that are considered to be services. Considering the tax revenue loss and the inequality between domestic suppliers and foreign suppliers when international transactions are not taxed, the Korean Tax Authority needs to amend the current law.

The consumption frequency, preference, purchasing behavior and satisfaction degree for bean sprout were surveyed from the housewives living in Seoul and Kyungki-do area. Most of the subjects (84.3%) took bean sprout less than 4 times per 21 meals. Major reasons for the rare consumption were the poor safety, habitual, and long cooking time, in deceasing order. Packed bean sprout was purchased more in Kyungki-do but unpacked was preferred in Seoul. While the major reason for purchasing unpacked bean sprout was the cheap price (57.8%), that for the packed was the safety (82.00). The most unsatisfactory factor for packed bean sprout was the high price, however, unlabelled additives were the primary concern for the unpacked. The satisfaction degree for the quality was higher in packed bean sprout compared with the unpacked. The most unsatisfactory factor for the quality of both packed and unpacked bean sprout was the overall acceptability, followed by texture, taste, and color.

The area of flat glass panel displays such as LCD (Liquid crystal display) and PDP (Plasma display panel) has been increased more than 2 $\times$ 2 m$^2$ for productivity improvement. However, such a large panel area incurs large panel deflection during panel transfer using robots or AGV (Automated guided vehicle) systems. Therefore, electronic industries are making an effort to find an alternative transfer system for the large glass panels with small deflection. The air conveyor with porous pads is one plausible solution, but it becomes expensive because the large porous pads cost much and air consumption increases as the panel area increases. In this work, a simple air slit levitating conveyor was devised to lower the equipment cost and to reduce the air consumption of system. The air flow model between the LCD glass panel and conveyor was constructed and its validity was verified by experiments. To minimize the air consumption, the conveyor dimensions were optimized, and the air consumptions between the air conveyors with the air slit and that with the porous pad were compared.

The purpose of this study is to take a new look at factors affecting the spending of retired elderly households by identifying the effects of different types of wealth components, along with socio-demographic factors, on current consumption. A tobit linear regression model was utilized to estimate parameters in the consumption functions. Data was drawn from the 1990 Consumer Expenditure Survey, Interview Survey in the United States.Total consumption and various consumption categories were the most responsive to changes in annual income flow and the least responsive to changes in property assets. The four wealth components differed in their influence on consumption categories among retired elderly households. In addition, age, residential area, household type, and education were found to be significant factors affecting total consumption and consumption categories of the retired elderly.

이 연구의 목적은 '윤리적 소비'를 실천하는 사람을 기르기 위한 가정교과 소비생활 영역의 교육과정을 제안하는 것이다. 이를 위해 본 연구에서는 먼저 윤리적 소비의 개념에 대한 학문적 고찰을 통해 윤리적 소비의 개념을 정립하였다. 윤리적 소비란, 인간의 삶을 행복하게 변화시키기 위해 개인적·사회적 책임을 다한 소비의 실천행위를 말한다. 이어서 본 연구에서는 가정교과 교육과정에서의 소비생활 영역이 어떻게 교육되어져 왔는가에 대해 살펴보고, 현행 가정교과 교과서에 제시된 윤리적 소비의 내용을 비판적으로 검토함으로써 앞으로 가정교과 소비생활 영역의 윤리적 소비 내용을 어떻게 가르칠 것인가에 대해 제안하였다. 첫째, 가정과 교육과정에서는 1차 교육과정부터 소비생활 영역의 내용이 제시되어 점진적으로 소비문화의 개념으로 질적 변화가 이루어져왔지만 책임 있는 소비와 윤리적 소비가 교육과정상에 제대로 반영되지 않고 있다. 둘째, 2015 개정 중학교 기술·가정과 교과서에서는 윤리적 소비에 대한 명확한 용어의 정의가 부족하고 개괄적인 내용만을 본문에 제시하고 있어 윤리적 소비에 대한 구체적인 실천방법을 제시하는 것이 필요하다. 셋째, 윤리적 소비실천을 위한 가정교과 교육과정의 방향은 책임이고 교육과정의 목표는 윤리적 소비실천을 위한 사회적 책임의식을 기르는 것이다. 윤리적 소비실천을 위한 가정교과 교육과정의 내용에는 소비와 소비생활, 지속가능한 소비, 윤리적 소비가 포함되어야 한다.
