In the coming future, anyone using the Internet will have more than one NFT. Unlike FT, NFT can specify the owner, and tracking management is easier than FT. Even in the 2022 survey, WPA2 is the most widely used wireless protocol worldwide to date. As it is a protocol that came out in 2006, it is a protocol with various vulnerabilities at this time. In order to use WPA2-EAP or WPA3 (2018), which were released to compensate for the vulnerabilities of WPA2, additional equipment upgrades are required for STA (station) and AP (access point, router), which are connected devices. The use of expensive router equipment solves the security part, but it is economically inefficient to be introduced in Small Office Home Office (SOHO). This paper uses NFT as a means of authentication and uses the existing WPA2 as it is without equipment upgrade, defend crack tools of WPA2 that have been widely used so far and compared to the existing WPA2, it was shown that it was not difficult to actually use them in SOHO.

The purpose of this study is to develop a computer software titled "Compare & Evaluation Program for Household Consumption". This software is developed in Microsoft Visual Basic 6.0. For the data of this program, the family Income and Expenditure Survey(1998) produced by the National Statistical Office in Korea is used. This program compares income and consumption expenditure for each household with those for standard household according to income level and family life cycle. This program gives information and suggestion for household consumers to manage rational household consumption. Also this study investigates validity and usefulness of the software program by interviewing 20 households used this program.

Permanent rental housing which is entirely financed by the Government is welfare housing for those who fall within the lowest income bracket. This type of housing is intended for use as rental housing on a long-term basis. At present, there are about 190,000 permanent rental housing units in Korea. The purpose of this study is to suggest the implications to improve the management and welfare service system of permanent rental housing. For this, qualitative data were collected by using the in-depth interview with staffs of community welfare center and management office of five permanent rental housing complexes and two times of advisory committee meeting with housing and social welfare experts. To analyze the data gathered in this study, the constant comparative method of data analysis was used. Conflicts between the management office and social welfare center of permanent rental housing could be classified into two aspects; personal and operational. Main reasons for the conflicts between two institutions were identified such as attitude of management office staffs, lack of cooperation, current administrative system, lack of management resources such as space and operation cost, and so on. Based on the results, some implications including institutional support and social complementary cooperation were suggested for improvement of management and welfare service system for the residents of permanent rental housing.

본 논문에서는 기존의 여러 가지 무선 홈 네트워크에 대해 개괄하고 새로운 표준인 Binary CDMA (Code Division Multiple Access)를 이용한 Koinonia 시스템을 제안한다. 제안된 시스템은 멀티 코드 CDMA 시스템을 고속의 멀티미디어 전송을 위해 변형한 형태이다. 멀티코드 사용 시 송신 신호 파형이 멀티 레벨로 나타나게 되어 시스템의 구조가 복잡해지고 가격이 비싸지는 단점이 존재한다. 이러한 기술적 문제점을 해결하기 위해 멀티레벨의 신호를 부호화 블록을 통해 정진폭으로 변환해 전송한다. 이를 통해서 복잡한 멀티 레벨의 신호가 간단히 나타나므로 전송되는 신호의 파형이 간단히 표현되어지고 수신기의 구조가 간단해진다. 그리고, 제안된 시스템은 멀티 코드 방식을 기반으로 하기 때문에 디지털 가전기기나 3세대 이동통신과, WPAN과 관련된 무선 네트워크 응용과 같은 미래의 고속의 무선 멀티미디어 서비스를 지원하기에 적합하다.

This study aimed to analyze residential demands on intelligent systems for apartments and suggest space design directions of intelligent apartment complexes. Data collection was done through mail-in surveys by five respondent groups. Outcomes of this study would provide basic data for developing intelligent apartment housing corresponding to the residential characteristics and demands of the five respondent groups. The sample size for the questionnaire survey was 592. The types of the target residents in this study were classified into five categories; nuclear families, dual income families, single households and the handicapped needing special environmental supports, and workers at home who need the new home design with a home office. The primary findings of this study were as follows. 1) For the controllers of intelligent system, nuclear families preferred TV, single households prefer home-pad which is movable and provides access to the internet. Dual income families, the handicapped and workers at home preferred remote control panels. 2) For the desirable space for computer equipment, regardless of the types of target residents, bedroom and living room were preferred. 3) For the desirable space for a home theater system, most of respondent groups preferred living rooms, but many rather wanted to have media rooms only for this system.

The COVID-19 pandemic has significantly impacted how people work, resulting in a massive shift towards working from home or remotely. Work from home has played a critical role in reducing the transmission of COVID-19 by limiting in-person interactions and reducing the density of people in office buildings. It also enabled businesses and organizations to continue operating while keeping their employees safe and healthy. The COVID-19 pandemic accelerated the adoption of work from home in business and organizational sectors worldwide, and it is likely to continue as a preferred mode of work even after the pandemic is over. This shift towards working from home has not only impacted the way people work but also has significant implications for urban development, transportation, and the environment. This study intends to develop measures for addressing potential physical and mental health issues among remotely working employees. Additionally, it identifies the major influencing factors of home workers' health hazards and proposes improvement measures that can be applied to working from home, along with existing laws and prevention methods.
