As the spatial structure of a region is evolving into a decentralized multi-nucli model, networked connection among cities in a region is emerging as an important issue to strengthen regional competitiveness. This paper focused on the limitation of current new town planning criteria which just suggest a uniform standard for economic self-sufficiency by new-town size, without representing the network characteristics of new town. If a new town is planned as a economic strongpoint within a region, it needs to secure appropriate industrial functions. This study classified the characteristics of new towns by network analysis and reviewed the economic self-sufficiency criteria by new town types. Using various network connectedness indices, the 1st and 2nd round new towns in the capital region were analyzed, and land-use distribution of new-towns in other countries were also examined comparatively. The network characteristics of new towns are classified as three types: mono-nucleus, distributed center, and dependent. Based on this classification, planning criteria for self-sufficiency were compared among 6 new towns. This study provides implications for the amendment of "the sustainable new town planning criteria" or the revision of development plans.

The quantitative assessment of the seismic collapse risk of a structure requires the usage of an optimal intensity measure (IM) which can adequately characterise the severity of the ground motion. Research suggests that the average spectral acceleration ($Sa_{avg}$) may be an efficient and sufficient alternate IM as compared to the more traditional first mode spectral acceleration, $Sa(T_1)$, particularly during seismic collapse risk estimation. This study primarily presents a comparative evaluation of the sufficiency of the average spectral acceleration with respect to ground motion duration, and secondarily assesses the impact of ground motion duration on collapse risk estimation. By assembling a suite of 100 historical ground motions, incremental dynamic analysis of 60 different inelastic single-degree-of-freedom (SDF) oscillators with varying periods and ductility capacities were analysed, and collapse risk estimates obtained. Linear regression models are used to comparatively quantify the sufficiency of $Sa_{avg}$ and $Sa(T_1)$ using four significant duration metrics. Results suggests that an improved sufficiency may exist for $Sa_{avg}$ when the period of the SDF system increases, particularly beyond 0.5, as compare to $Sa(T_1)$. In reference to the ground motion duration measures, results indicated that the sufficiency of $Sa_{avg}$ is more sensitive to significant duration definitions that consider almost the full wave train of an accelerogram ($SD_{a5-95}$ and $SD_{v5-95}$). In order to obtain a reduced variability of the collapse risk estimate, the 5-95% significant duration metric defined using the Arias integral ($SD_{a5-95}$) should be used for seismic collapse risk estimation in conjunction with $Sa_{avg}$.

This study analyzed the changes of welfare and labor market status of participants of Self-sufficiency Support Program in Korea thorough of analysis follow-up data which were collected about the experiences and changes of participants of the program in Gyeonggi province in 2005. As the results, many of participants exited from the program within five years, and hardly anyone depends on the welfare or the program, also there is very little the revolving door phenomenon. Whatever, the program have positive effects the changes of welfare and labor market status of them. Also, self-sufficiency communities, the small enterprises are started by more two participants and aim the economic independence of them and contribution to social economy have played important role for their persistent work and economic self-reliance. The people exited from the program, however, hardly succeed in exit from the welfare and their economic conditions still are not good. Therefore, we have to arrange the program for the participants' self-sufficiency, and we rather have to effort to secure their economic well-being than emphasize the immediately employment or establishment a business.

Objective : To establish a standard for discriminating between deficiency syndrome and excess syndrome and selecting reinforcing or reducing method. Methods :Deficiency syndrome and excess syndrome were divided into excess of pathogenic factor with sufficiency of vital energy syndrome, weakness of pathogenic factor with deficiency of vital energy syndrome and excess of pathogenic factor with deficiency of vital energy syndrome. Documentary survey was done for each case. Results : Excess of pathogenic factor with sufficiency of vital energy syndrome is an excess syndrome and a reducing method must be used. Weakness of pathogenic factor with deficiency of vital energy syndrome is a deficiency syndrome and a reinforcing method must be used. Excess of pathogenic factor with deficiency of vital energy syndrome is related to deficiency syndrome and a reinforcing method must mainly be used. Conclusions :Deficiency or sufficiency of vital energy is the standard for discriminating between deficiency syndrome and excess syndrome and selecting a reinforcing or reducing method.

Until recently, Japanese cuisine was known only for sushi and was still considered exotic outside the archipelago. However, today the number of specialized restaurants which serve other traditional foods is constantly increasing all over the world, making Japanese gastronomy one of the most influential. Japanese government has supported the promotion of national cuisine worldwide in different ways, making washoku (Japanese traditional cuisine) one of the main elements of Japan's soft power and cultural diplomacy. In this paper, I will analyse the connection between Japan's gastrodiplomacy, defined as the use of typical food and dishes as an instrument of soft power, and Japan's food security strategy. I will argue that the strategy of promotion of washoku worldwide is not a mere act of popularization of Japanese food but it is strictly related to the issue of the low self-sufficiency rate of the country, as the main objective of the government is the raise of food export, in order to foster agricultural production and improve self-sufficiency.

It is well-known that the sample mean and the sample variance are jointly sufficient under normality assumption. In this paper a proof of the joint sufficiency is given without using the factorization criterion. It is related to a finite Sanov-type conditional theorem, i.e., the conditional probability density of $Y_1$ given sample mean $\mu$ and sample variance $\sigma^2$, where $Y_1, Y_2, \cdots, Y_n$ are independently and identically distributed (i.i.d.) normal random variables with mean m and variance $\delta^2$, equals that of $Y_1$ given sample mean $\mu$ and sample variance $\sigma^2$, where $Y_1, Y_2, \cdots, Y_n$ are i.i.d. normal random variables with mean $\mu$ and variance $\sigma^2$.

Permanent rental housing complex is subjected to both an increase in the crime rate due to its residential population structure and social, economic isolation for insecurd income of the residents. It should be considered that the densely populated area with low-income group of the city causing many problems related with the community. This study focused on the Man-soo 7 housing estate in Incheon with the area's average scale and ratio is made as an effort to include the residents who live in the permanent rental housing area among the members of the healthy community. The result of the research suggests the method of housing improvement to establish the successful support institution for self-sufficiency of the low income inhabitants analazying the demand of the residents through a survey categorized into resident support system, public workplace and inhabitant participation.

Food Self-sufficiency rate in Korea was 26.4 percent in 1996. It include $89.9{\%}$ for rice, $99.6{\%}$ for root and tuber crops, and $73.5{\%}$ for barley. To make things worse, self-sufficiency for wheat and corn were far less than 1 percent. As food is considered as weapon, every effort should be given to increase the self-sufficiency. In order to cope with expected food crisis, we suggest wheat and barley be grown in winter period, where there is climate fit. The aim of this paper is to survey systematically the status of food supply and demand of wheat and barley and to encourage farmers make double cropping systems with better stability in yield and economic return.

In recent years, selection of strong ground motion records by means of intensity measures representing the spectral shape of the earthquake excitation has been studied by many researchers. These studies indicate the adequacy of this record selection approach in reduction of the scattering of seismic responses. In present study, this method has been studied more in depth to reveal the sufficiency of the spectral shape in predicting structural seismic responses such as the plastic deformation and the dissipated hysteresis energy which are associated with cumulative properties of the selected records. For this purpose, after selecting the records based on the spectral shape, the correlation of some seismic responses and strong ground motion duration of earthquake records are explored. Findings indicate strong correlation of some structural responses with the significant duration of the records. This fact implies that the spectral shape could not reflect all characteristics of the strong ground motion and emphasizes the importance of additional criteria along with the spectral shape in the record selection.
