The purpose of this study is to explore the concept of social exclusion and underclass and to find out their implication for the poverty policy in Korea. Social exclusion as a concept, on the other hand, offers a broader perspective in addressing multi-dimensional disadvantage, especially in relation to social policy. The term underclass offers a convenient metaphor for use in commentaries on inner city crises because it evokes three widely shared perceptions: novelty, complexity, and danger. Conditions within inner cities are unprecedented; they cannot be reduced to a single factor; and they menace the rest of us. Open debate on the underclass accelerated in 1977 when Time magazine announced the emergence of a menacing underclass in America's inner cities. Drugs, crime, teenage pregnancy, and high unemployment, not poverty, defined the 'underclass,' most of whose members were young and minorities. With the publication in 1982 of Ken Auletta's Underclass, the word secured it dominance in the vocabulary of inner-city pathology. As implications for Korean poverty policy of the concept of social exclusion and underclass, the establishment of multi-dimensional concept of poverty, development of multi-dimensional approach of social work, improvement of National Basic Life Guarantee System, research on employment policy in social welfare field, and research on housing policy for the poor were suggested.

Lactiplantibacillus plantarum (L. plantarum) ST was isolated from De'ang pickled tea in Yunnan Province, China. The genomes of strain ST were fully sequenced and analyzed using the PacBio RS II sequencing system. Our previous study has shown that L. plantarum ST is a potential probiotic strain. It had strong tolerance in the simulated artificial gastrointestinal tract, and in the antagonism tests, this strain showed strong antibacterial activity. Therefore, as a probiotic, it may be used in animal breeding. L. plantarum ST genome was composed of 1 circular chromosome and 7 plasmids. The length of the whole genome was 3320817 bp, and the annular chromosome size was 3058984 bp, guanine + cytosine (G ± C) content (%) was 44.76%, which contained 2945 protein-coding sequences (CDS). This study will contribute to a further comprehensive understanding of L. Plantarum ST at the genomic level and provide a theoretical basis for its future application in animal breeding.

The research follows several steps. First, the chinese 'WangSung' and 'KungSi' System are verified positively. Next, the structure of palace in Choson Dynasty is deduced based on those chinese systems. Finally, the common system that is also applied in other government-operated spaces is found. The result can be summarized as follows. It is clarified from reviewing the chinese 'WangSung' and 'KungSil' Systems that the 'OyoiCho' is located in 'WhangSung(the imperial city) but out of' KungSung(the palace). Therefore, the research points out that all sort of theories explaining the 'OyoiCho' of Choson Dynasty is a space of 'in-place' are false. The palace system of Choson dynasty seeks the substantiality grounded on the substantial function of 'SamCho(three spaces)' rather than its strict principle dividing main spaces by several doors-'KungMoon' Moreover, it is also certified that the 'ChonChoHooChim' system, literally the political court is located at the front and the private section is at the other(back) side, is directly applied on the palace of Choson Dynasty. This idea has been developed into 'inner and outer' concept and repressed in palace as the 'OyoiChon(outer palace) and NaeChon(inner palace)' concept. conclusion, the research suggests that the dual concept in space such as 'ChonHoo(front and back) and 'NaeOyoi(inner and outer)' basically comes from 'Eum Yang' theory and influences in building other government-operated spaces: for example 'ChongMyo(the royal ancestors shrine)', 'SoWon(a private school of Choson dynasty), 'HyangKyo(a local school annexed to the Confucian shrine)' and 'KwanAh(a governmet agency)'

Purpose: With gold electroforming system fir the double crown, the secondary crown is electroformed directly onto the primary crown. An even thick layer of high precision can be acquired. It is thought that the retention of electroformed outer crown is primarily acquired by the adhesive force (surface tension) through the saliva which is interposed between precisely fitted inner and outer crown. The purpose of this study was to investigate the effect of taper and surface area of inner crown on the retentive force of electroformed outer crown according to the presence of saliva. Materials and methods: 32 titanium inner crowns with cervical diameter of 8 mm and cone angles of 0, 2, 4, 6 degrees, which had same surface area by regulated height, were machined on a lathe. Another 32 titanium inner crowns with cone angles of 0, 2, 4, 6 degrees, which had doubled surface area by increased cervical diameter. were fabricated. Eight specimens of each group, for a total of 64 titanium inner crowns, were prepared. The electroformed outer crowns were fabricated directly on the inner crowns by using electroforming machine(GAMMAT free, Gramm Technik, Germany). The tertiary frameworks were waxed-up on the electroformed outer crown and cast using nonprecious alloy($Rexillium^(R)III,\;Jeneric^(R)/Pentronh^(R)$ Inc., USA). The cast metal frameworks were sandblasted with alubimium oxides and cemented using resin cement(Superbond C&B, Sun Medical Co., Japan) over the electroformed copings of each specimen. Then, artificial saliva($Taliva^(R)$, Halim Pharm. Co., Korea) was sprayed between the inner and outer crown, and they were connected under 5 kg force. The retentive force was measured by the universal testing machine(Tinius Olsen 1000, Tinius Olsen, USA) with a cross-head speed of 66.67 mm/sec. The direction of cross-head travel was exactly aligned with the path of removal of the respective specimens. This measurement procedures for retentive force of electroformed outer crown with artificial saliva were repeated in the same way without presence of artificial saliva. Results and Conclusion: The following conclusions were drawn: 1. The retentive force of electroformed outer crown was decreased according to increased taper of inner crown(P<.05). 2. The retentive force of electroformed outer crown showed no significant differences according to surface area and the presence of artificial saliva(P>.05).

산업화 초기부터 발전해온 내항은 이후 변화한 산업물류 환경 속에 쇠락해왔으나 재개발을 통해 새로운 용도로 변모하면서 다시 도시적 활기의 중심이 되기도 한다. 우리나라도 내항 재개발 필요성을 인식하고 이를 지역 재생을 위한 도구로 활용하려는 정책을 추진하고 있다. 이 연구는 내항의 개발은 도시와 해양 사이에 위치한 내항의 독특한 입지 특성에 대한 이해와 분석을 전제로 해야 한다는 인식을 토대로 개발 방향을 제시하고자 하였다. 이를 위해 주요 내항지역 사례들을 선정하고 이들의 입지를 두 가지 개념, 즉 관문적 개념과 중심지이론적 개념을 통해서 비교분석하였다. 이를 통해 내항의 여건을 객관적으로 판단하고 두 가지 개념을 통해 유형화함으로써 각 내항의 특성에 맞는 개발 방향을 제안하였다. 이러한 과정에서 고립적인 입지, 시가지와 해안의 분리 등으로 인해 내항이 가지는 잠재력이 충분히 구현되기 어려운 사례가 많음이 드러났으며, 그에 대한 인식과 대처가 없이는 효과적인 재개발이 쉽지 않음을 파악할 수 있었다. 내항을 별도의 또 다른 가용지로 보기 보다는 해양과 내륙을 매개하는 입지, 기존 시가지와 연계된 입지로 보고 접근하는 개발 전략이 필요하다. 내항 지역의 개발을 해양문화시대, 도시재생 시대에 필요한 기회로 활용하기 위한 중장기적인 노력이 있어야 할 것이다.

In several years, the geographic information system has been being applied into various departments, i.e. estate, transportation, prevention against disasters, agriculture, environment, etc. Especially, it is very useful for us to manage the infrastructures of urban transit which are scattered and located in the vast areas of city. But, in the 2D geographic information system, it is impossible to manage the various inner facilities of stations which are in the same spatial location on GIS. Then, the 3D station management system has been developed for the efficient management of station facilities in urban transit. Through this system, from the virtual cyberspace of station on PC, we can move and go to any places of station we want without going to the station fields. So, we can manage the various information of location information, basis information, maintenance information about the inner facilities such as architectural structures, machinery facilities, electronic equipments. And, this system is also connected with the drawings and technical documents in each facilities. So, we're sure, this system will improve the efficiency of maintenance work and information management of stations.

In order to determine possible relationships between the renin-angiotensin system and nephron heterogeneity, we compared the response of renin release and the angiotensin-converting enzyme (ACE) activity from different areas of the rat kidney. We used the renal cortical slices from the capsular surface to the juxtamedullary junction. Slices from outer one-third of the cortex were designated as outer cortical slices (OC), middle one-third as midcortical slices (MC), and inner one-third as inner cortical slices (IC). The renal renin content markedly decreased from OC and MC to IC. The basal lenin release was higher in OC than in MC or IC. On the contrary the percent change of renin release in response to L-isoproterenol was significantly higher in MC than in OC or IC. By TMB-8, the renin release in MC by $231{\pm}21%$ was higher than OC by $171{\pm}19%$ or IC by $$162{\pm}19. Angiotensin II suppressed renin release in OC and MC by $68{\pm}2,\;71{\pm}4%$ respectively, but only $40{\pm}7%$ in IC. The ACE activity was higher in IC than in OC, MC, medulla and papilla. The present data indicate that renin content and basal lenin release gradulally decreased from outer (OC) to inner (IC) cortex. The renin release in response to beta-adrenergic agonist, L-isoproterenol and intracellular calcium antagonist, TMB-8 were higher in MC than in OC and IC, but angiotensin II suppressed renin release less in IC than in OC and MC. It is suggested that juxtaglomerular cells of outer, mid-and inner cortices show a difference in renin release response to the stimuli.

This paper describes a methodology using neural network to compensate the nonlinear error of deriving speed for electric differential system included in electric vehicle. An electric differential system which drives each of the left and right wheels of the electric vehicle independently. The electric vehicle driven by induction motor has the nonlinear speed error which depends on a steering angle and speed command. When a vehicle drives along a curved road lane, the speed unblance of inner and outer wheels makes vehicles vibration and speed reduction. To compensate for the speed error, we collected the speed data of the inner wheel and outer wheel in various speed and the steering angle data by using an manufactured electric vehicle and the real system. According to the analysis of the acquisited data, we designed the differential speed control system based on a speed error compensator using neural network.
