Currently the number of unsold housing is rapid increasing over again in the Seoul Metropolitan area. So this research analyzed effective and possible solutions focus on the potential customers and professionals. There was a research method setting up alternative solutions from the existing researches and the other suggestions though FGI (Focus Group Interview) by professionals. And then it investigated the efficient ways to resolve those problems through Conjoint Analysis. According to the result of this paper, firstly the customers considered 'financial supports', 'self-rescue efforts for construction companies' and 'taxation support' than the other. On the other hand, professionals evaluated 'publicly purchased housing' and 'new housing policies' were more essential solutions besides, both of them recognized the importance of ;financial support'. Secondly there were some ideas that it was necessary to more less control LTV (Loan to Value ratio) and DIT ( Debt to Income) and the LH (Korea Land and Housing Corporation) buy unsold housing. Finally the government and housing association had to manage and intervene the supply of housing within metropolitan area and restrict to building new properties and the construction companies actively provide less strict standard terms and conditions in contract for purchasing housing for instance, the decline of housing sale price or interest-free and so on.

With the government policy on converting contract workers to full-time employees, there have been significant changes about the security personnel at the nation's critical facilities, including the National Assembly Building and airports. Moreover, the scheduled disbandment of the conscripted police force in 2023 has raised concerns about security management at different government agencies. To examine the college students' perceptions on the possible alternatives to fill the expected security gap, 234 undergraduate students of security management and protection in the Seoul metropolitan region were surveyed. Particularly, a comparative analysis was conducted on the legal bases and supervision, the employment types and salaries, and the scopes of responsibility and authority of suggested alternatives were compared. The results showed that utilization of private police forces was thought to be the most effective option. Based on the research findings, the university departments should develop and maintain a quality curriculum to educate their students to be prepared security professionals with a focus on emergency response capabilities and martial arts, including the courses on private police law and emergency rescue and cardiopulmonary resuscitation (CPR).

The absence of fire fighters' connection to communication can bring about increased loss of life due to errors and delays in rescue and actions and danger to their own safety. Therefore, when communication infrastructure has been destroyed in an enclosed space, it is necessary to set up an emergency wire or wireless telecommunication environment to fire fighting and to secure safer environment to deal with the disaster by checking the location of fire fighters. In this research, for the establishment communication environment in an enclosed inside using Ultra-Wide Band (UWB) wireless communication network, the performance of communication position determination of a single UWB communication module was evaluated regarding 6 kinds of indoor surroundings. When the communication distance in an indoor environment of each 6 channels bandwidth of UWB communication frequency was measured, the results were as follows: the open space (Ave. 15.5 m, Max. 20 m), the corridor (Ave. 17.33 m, Max 20 m), inside retaining home furnishings (Ave. 15.3 m, Max. 20 m), vertical stairs (Ave. 4.33 m, Max. 6 m), horizontal space with a closed fire door (Ave. 6.5 m, Max. 17 m). It was also found out that the communication function and the distance function were best in the frequency range from 6489.6 to 1081.6 MHz by 7 Ch. Accordingly, the establishment of communication environment in an enclosed space is judged to be possible when UWB communication module is set up at 20 m apart and multiple channels are used.

The introduction of doubled haploid (DH) approach into breeding programs has reduced the times and population sizes required for the production of pure lines. We carried out the experiment for development on effective method of producing haploid in wheat. Emasculated spikelets of wheat were pollinated with maize pollen and cultured in the solution containing 40 g/L sucrose and 2,4-D, NAA, 2,4,5-T and dicamba 24 h after pollination, and then incubated until embryo rescue. Fourteen to sixteen days after pollination, the embryos are excised and cultured in half-strength MS basal medium supplemented with 20 g/L sucrose and 1 mg/L NAA. The type of plant growth regulators was found to be most significant in production of haploid plants. The application of synthetic auxins to pollinated florets, stimulates haploid embryo development to a stage where the embryos can be rescued onto nutrient media. The percentage of seeded florets was significantly affected by 100 mg/L 2,4-D, 150 mg/L 2,4,5-T and 50 mg/L dicamba. The percentage of embryos formed was significantly increased by treatment with 2,4-D and 2,4,5-T at 100 mg/L, and dicamba at 50 mg/L, but the treatments with 150 mg/L 2,4-D inhibited embryo development and plant regeneration. The optimum application time of plant growth regulators was 24 hrs after pollination.

A FA intersectional hybrid lily cultivar 'Cherry Pink' was developed in 2006 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) Korea. The cross and immature embryo rescue was conducted between female parents Lilium FA hybrid 'Supia' and male parents L. Asiatic hybrid 'A94-9' by cut style pollination method (CSM) at Suwon in 1999. The first selection was done and was tentatively named as 'FA01-17' in 2001. After in vitro multiplication, bulbing production of 'FA01-17' line, growth and flowering characteristic tests were conducted from 2002 to 2005. The evaluation of characteristics and consumer preferences were surveyed at a lily flower show of NIHHS at Taean in 2006. 'Cherry Pink' flowered in the middle of June and grew more than 120 cm stem in length. Flowers bloomed facing upward, a little spotted in petals and deep pink (RHS, RP27D). The pollen of 'Cherry Pink' was sterile. Year-round flowering can be done by storing the bulb under $-1.5^{\circ}C$ conditions. It was needed to control Botrytis disease in wet season.

This research utilized the Grounded Theory and Giorgi's phenomenological research method to analyze the experience of battered women who are maintaining a non-violent marriage relationship. Due to the low accessibility of subjects and the distinctiveness of the topic, I have selected 4 participants and conducted in-depth interviews. As for data analysis results, there were 5 superior component elements and 19 inferior component elements for the experience of maintaining a non-violent marriage relationship and these appeared according to time. Thus, it can be analyzed as follows: 'the vicious cycle stage of violence: caught in a trap,' 'stage of breakaway from vicious violence cycle: making the self-rescue measures,' 'entry to a new track: retrieval of autonomy,' 'stage of forming a non-violence track: preventing the recurrence of the violence,' 'stage of maintaining non-violent track: conversion to non-violent relationship.' This research result will be useful in seeking an effective social welfare intervention plan for successful non-violent relationship in order to help 50% of the battered women from family violence who wish to maintain marriage.

In response to possible HNS (Hazardous and Noxious Substance) spill accident, HNS spill accident scenario and response scenario were developed. The accident area listed in scenarios is the coastal area of Busan, and scenario for possible accident in the designated area and strategies to respond the accident were developed, respectively. The scenario for accident was developed by designating HNS spill according to risk evaluation of HNS and analysis of HNS spill probability along the coastal area of Busan, and then estimating possible and potential impact from the accident. The scenario for response has been suggested as a systematical responding operations in order to effectively reduce the estimated impact from the accident. The possible HNS spill accident on the seas around Busan, has been designated by the spillage of 1,000ton of xylene due to collision accident in Gamcheon Port, and the possible impacts occurred by the accident has been simulated with the help of the atmospheric and oceanic dispersion model of xylene. In the responding scenario for the accident, a phased strategies regarding emergency rescue of peoples, protection and recovery of xylene, protective measures for the responders, and post management of the accident have been suggested.

The importance of "Golden time", the early hours for saving lives in case of an accident, is being increasingly recognized day by day. Especially for marine accidents, it may take several hours for a rescue team to arrive, depending on location. Therefore, captains should always be prepared to handle situations independently. In this paper, in order to make better use of Golden Time in an emergency, we determined what the first consideration should be when selecting a ship evacuation route from perspective of the ship operator. To achieve this, we used maritime accident judgments and ship emergency response manual to identify ship evacuation priorities. AHP analysis (decision-making hierarchy analysis) was conducted for ship operators to determine consideration priorities. As a result, it was found that ship operator consider the safety of people about 6 times more important than that of the actual ship. In order to select an evacuation route, the location of coast guard ships, port of refuge, emergency anchorage, surrounding vessels, drifting and beaching factor are taken into consideration. By using these priority considerations, the decision-making processes of ship operators in emergency situations can be improved.

Harnesses are used in a variety of industries, such as rescue operations, medicine, and entertainment. However, conventional harnesses have problems as they are uncomfortable to wear and causes continuous pain. Therefore, in this study, the load and pressure applied to the body in the flying state when using a conventional harness were measured in real time and the distribution change was observed. Load and pressure were measured using a modified corset harness, a pressure sensor, and a human mannequin to measure the maximum and average pressure on the waist. As a result, it was confirmed that the load concentrated on the waist in the flying state was 104 N, and the pressure was applied to the left and right sides was 800 kPa or greater. The pressure distribution showed a pressure of 3-45 kPa in 73% in all measurable pressures. The results of the load and pressure distribution are presented as basic data for improving the wearability and reducing the discomfort of harnesses in the future, aid in the development of a harnesses that can minimize discomfort for various activities, and increase the concentration on experiential activities. In addition, using the CLO 3D program, which is a 3D virtual wearing system, a harness was put on a virtual model, and the compression level was checked and compared with the actual pressure distribution. As a result of comparing the measured pressure values in the flying state with the clothing pressure wearing the harness in the CLO 3D program, the total pressure value was found to be about 68% of the actual measured value. This helps develop a harness that can minimize discomfort during activities by predicting the load and pressure on the body by first applying new designs to a virtual wearing system during development. These new harness patterns can solve the problems of conventional harnesses.
