This qualitative study aimed to explore and understand the impacts of the poor neighborhood on children from their own perspectives. To this end, the meaning and the structure of children's lived experiences were explored. The participants were recruited from elementary school high grade students living in poor neighborhood. Focused group interviews were conducted in each of the 24 World Visions social work agencies. The collected data were analysed qualitatively. According to the results, the following main themes could be extracted from the children's lived experiences: "Conflict between connection and differentiation", "Resigning to the fate of being neglected in danger" "Learning to live in the dark cave", "Anticipating a bowl of trust from the neighborhood". The children living in poor neighborhood were threatened by the physical and emotional danger highly probable in weak social infrastructure. Also, they have internalized negative self-identity by chaotic environment and, even the negative role models from alcoholic and sometimes violent adults. However, they were experiencing positive caring from and solidarity with surrounding neighborhood, and were participating in volunteered activities for asserting their citizen rights. These may be the keys to empowerment and, ultimately, to change for themselves and the community. The implications of the study results for the policy making and the actual practice were discussed focusing on the children's rights and well-being.

This paper verified the characteristics of electrical continuity and mechanical strength of steelwork required to use it as a down-conductor in lightning protection system. It was proven that the steelwork in reinforced concrete apartment has an excellent electrical continuity with low resistance(less than 0.2[${\Omega}$].). But it was confirmed that a poor connection between two reinforcement bars can easily cause serious damages of the concrete even with the impulsive current of 50[kA], 10/350[${\mu}s$]. These results of experiments mean that the additional measures are necessary in using the steelwork as the down-conductor of the lightning protection system.

The rebuilding method for old apartment housing blocks has merits of providing new buildings and larger private living spaces. However, it causes many serious urban problems, such as shortage of infrastructure capacity, traffic congestion, reduction of building life, and deterioration of open space quality. Nowadays, remodeling is accepted as a way of overcoming such negative effects of the rebuilding method. This study focuses on the various techniques of remodeling. The results of this research are as follows; First, old apartment blocks provide poor level of service in general, so they have problems of bad accessibility, deterioration of facilities, and degraded landscape. In many cases, there is a hindrance from walking freely and security problem due to illegal privatization of public spaces. Second, various remodeling techniques are required to meet residents' different needs. The residents of apartment housing value private space above public space, and show low level of willingness to pay cost for remodeling. Third, based on these findings, some remodeling techniques are suggested - integration of a space to another, expansion of spaces, connection of spaces, reuses of roofs and walls, relocation and renovation of paths between buildings, and so on.

This plan is for a different type of welfare facilities devised by analyzing problems with existing welfare centers and focusing on connection with residents and link between culture and welfare and among generations. In terms of re-development plan of Youngsun-2-dong, Youngdo-gu, Busan and the neighborhood under this plan, Youngsun-dong, Youngdo-gu is one of the densely populated districts of the aged, with lower growth rate and poor housing and welfare facilities. However, the district has a blessed natural environment and historical site of cultural relics of the Neolithic Age as well as growth potential as a logistics center with broader network of roads linking with Bukhang Bridge when Namhang Bridge construction is complete, showing the aspiration for change toward hi-tech maritime city in the 21st century of Youngdo-gu. This plan is expected to promote unity between the old and children, protection from social marginalization, and re-socialization education and set the stage for participation and solidarity of residents in the community.

Using SOHO particle and EUV detection and radio spectrograms from both ground-based and spaceborne instruments, we have studied the first phase of major solar energetic particle (SEP) events associated with wide and fast coronal mass ejections (CMEs) centered at different solar longitudes. Observations support the idea that acceleration of SEPs starts in the helium-rich plasma of the eruption's core well behind the CME leading edge, in association with coronal shocks and magnetic reconnection caused by the CME liftoff; and those "coronal" components dominate during the first ~1.5 hour of the SEP event, not yet being hidden by the CME-bow shock in solar wind. At magnetic connection to the eruption's periphery, onset of SEP emission is delayed for a time of the lateral expansion that is visualized by global coronal (EIT) wave. The first, "coronal" phase of SEP acceleration is followed by a second phase associated with CME-driven shock wave in solar wind, which accelerates high-energy ions from a helium-poor particle population until the interplanetary shock slows down to below 1000 km/s. Based on these and other SOHO observations, we discuss what findings can be expected from STEREO in the SOHO era perspective.

In recent years, behavioral disorders of young people and juvenile delinquency tend to increase remarkably in number, and closed up highly as a social and educational problems in Korea. It goes without saying that parents generally play important roles in children's development of personality, and the home is mostly responsible for juvenile delinquency. Therefore, first this paper describes a relation between broken family and juvenile delinquents. Burt, Shideler, Neumayer, and Glueck maintain that broken family is a cause of delinquency, on the other hand, Healy and Sutherland assume a critical attitude toward their contentions. Second, Breckinridge, Merril, and Glueck maintain that poor family is as cause of delinquency, while Sullenger, Neumayer, and Dirksen make a considerable point which poverty has no direct connection with delinquency. Third, abnormal family relationships namely, discord family, abnormal parent-child relationship, and immoral family exert a bad influence upon formation of personality, esepecialy during the period of preschool childhood. These results give some empirical support to the theory that children's conduct disorders and juvenile delinquency are caused by defective family relationships. It is necessary that a community has a supporting structure of children's wholesome development and the prevention of juvenile delinquency.

The author attempted the taxonomical studies on yeasts in Takju mash. The samples used for the isolation of yeasts were collected from Takju breweries in Seoul. The yeasts obtained from Takju were identified as follows using the methods of Lodder et al. ; Saccaromyces cerevisiae group II, Saccharmyces cerevisiae group III, other group of Saccharomyces cerevisiae, Hansenula anomala and Pichia polymorpha. Saccharomyces cerevisiae II & III and other group Saccharomyces cerevisiae which were considered as wild yeasts have shown their major role in the fermentation process of Takju brewing. It seems that Hansenula anomala has much connection with the flavour of Takju. Other strains which are poor in their acoholic fermentation and lower in activity of acid production are not considered to be important in Takju brewing.

Mobile handhold devices such as PDA(Personal Digital Assistant) and Cellular Phone are more and more popular for personal web surfing. But today, most mobile handheld devices have relatively poor web browsing capability because of the small bandwidth of wireless connection, the small speed of CPU, the small capacity of RAM and Flash ROM, the small display size of LCD and the short lifecycle of battery. Users have to endure bigger communication latency than Desk PC's one because of these factors. In this paper, we propose an effective pre-refresh mechanism for handheld device's embedded web browser so as to make user's web surfing faster. The experiment was done using the simulator designed by ourselves and the experiment result demonstrates the proposed mechanism has a good performance to make web surfing faster.

A new switching mode has been proposed to obtain high power factor and low THD in single stage AC-DC converter. The conventional voltage mode control in critical conduction mode distorts input current shape with poor THD in flyback topology. Once TRIAC dimmer is connected, visible flicker in the LED lamp is easily detected due to a lack of TRAIC holding current near the input voltage zero cross. The newly proposed method can shape the input current by providing a desired reference voltage so that low THD is obtained by ideal sinusoidal input current in case of no dimmer connection and flat input current performs good TRIAC dimmer compatibility in phase-cut dimming condition. To confirm the validity of the proposed method, theoretical analysis and experimental result from 8W dimmable LED lighting system are presented.
