The pattern of economic integration in the broiler industry can be grouped into three categories; 1) non-integration, 2) quasi-integration and 3) complete-integration. It is general to see that the non-integration is quite common under the market conditions of perfect competition, whereas the complete integration is more preferable in the imperfect competition. The quasi-integration, however, exists at all phases where the complete integration is not fully formed and implemented, but the non-integration has begun to alter its nature into integrated structure. The broiler industry in Korea has been characterized with the typically non-integrated independent operation, resulting in considerable price fluctuation and unstable industry as a whole. As a means of solving out the problem stemed from the non-integrated, growers and agribusinessmen involved in broiler industry have tended to develope the regular customer relationship prevailed between two parties. In fact, it has been practiced for years that most growers have been dealt with factor suppliers or processors on a regular basis for advantages of better price and quality, useful information, management help and so forth. Under the customary transaction, no formal contract has been made due to simple buyers and sellers relations, not like the one used to be performed in the form of contractual agreement. The broiler industry realizes the direction to go ahead toward the formal arrangement of integrated system from current regular transactions. As more Vowers, suppliers and processors recognize the necessity of it, the non-integrated industry appears to become the partially integrated by developing the existing customer relationship in such a way that functions of integrators are. further expanded and better organized. As a result, a type of quasi-integration started to show up by an integrator dominated in the field of hatching, feedmilling, dressing and by a grower's coop, It is concluded, therefore, that the evolution of quasi-integration in Korea's broiler industry is continuously taking place, implying the close approach to the completely integrated broiler production and marketing system.

This paper presents an approach to the construction of non-binary quasi-cyclic (QC) low-density parity-check (LDPC) codes based on multiplicative groups over one Galois field GF(q) and Euclidean geometries over another Galois field GF($2^S$). Codes of this class are shown to be regular with girth $6{\leq}g{\leq}18$ and have low densities. Finally, simulation results show that the proposed codes perform very wel with the iterative decoding.

Let R be a ring with identity, X(R) the set of all nonzero, non-units of R and G(R) the group of all units of R. We show that for a matrix ring $M_n(D)$, $n{\geq}2$, if a, b are singular matrices of the same rank, then ${\mid}o_{\ell}(a){\mid}={\mid}o_{\ell}(b){\mid}$, where $o_{\ell}(a)$ and $o_{\ell}(b)$ are the orbits of a and b, respectively, under the left regular action. We also show that for a semisimple Artinian ring R such that $X(R){\neq}{\emptyset}$, $$R{{\sim_=}}{\oplus}^m_{i=1}M_n_i(D_i)$$, with $D_i$ infinite division rings of the same cardinalities or R is isomorphic to the ring of $2{\times}2$ matrices over a finite field if and only if ${\mid}o_{\ell}(x){\mid}={\mid}o_{\ell}(y){\mid}$ for all $x,y{\in}X(R)$.

An automated process planning system for cold forging of non-axisymmetric parts of comparatively simple shape was developed in this study. Programs for the system have been written with Visual LISP in the AutoCAD using a personal computer and are composed of four main modules such as input module, shape cognition and shape expression module, material diameter determination module and process planning module. The design rules and knowledges for th system are extracted from the plasticity theories. handbook, relevant reference and empirical knowledge of field experts. Generally, in forging, only front view is needed for expression of axisymmetric parts, but non-axisymmetric parts are needed both front view and plane. At the plane, this system cognizes the external shape of non-axisymmetric parts - number of sides of regular polygon and radius of a circle circumscribing the polygon of n sides. At the front view, the system perceives diameter of axisymmetric portions and hight of primitive geometries such as polygon, cylinder, cone, concave, convex, etc.

본 연구에서는 파랑이 존재하는 수역에서 수평방향으로 분사되는 비부력 원형 난류제트의 거동을 검토하기 위해 수리실험을 수행하였다. 난류제트의 유속은 PIV(particle image velocimetry)기법을 이용하여 측정하였으며, 측정된 순간유속장을 위상평균하여 평균유속장으로 계산하였다. 수리실험에서는 상대적으로 작은 파고의 규칙파가 사용되었으며, 파랑의 분산이 난류제트의 확산현상에 미치는 영향을 제트의 중심선유속과 횡단면유속의 변화를 통하여 관찰하였다. 또한 파랑의 위상변화에 따른 제트 거동을 파악하기 위하여 다른 세 위상순간에서 제트의 거동을 비교하였다. 제트의 중심선유속은 파고가 커짐에 따라 감소하였으며, 횡단면의 폭은 증가함을 알 수 있었다. 제트의 횡단면유속분포 특성인 자기상사성은 파고가 증가할수록 약해졌으나 축방향으로의 단면폭의 변화는 크지 않았다. 또한 파고에 대한 제트의 변화에 비해 파랑 위상에 대해서는 변화가 작음을 알 수 있었다.

The aim of this note is to study properties of the generalized centroid of the semi-prime gamma rings. Main results are the following theorems: (1) Let M be a semi-prime $\Gamma$-ring and Q a quotient $\Gamma$-ring of M. If W is a non-zero submodule of the right (left) M-module Q, then $W\Gamma$W $\neq 0. Furthermore Q is a semi-prime $\Gamma$-ring. (2) Let M be a semi-prime $\Gamma$-ring and $C_{{Gamma}$ the generalized centroid of M. Then $C_{\Gamma}$ is a regular $\Gamma$-ring. (3) Let M be a semi-prime $\Gamma$-ring and $C_{\gamma}$ the extended centroid of M. If $C_{\gamma}$ is a $\Gamma$-field, then the $\Gamma$-ring M is a prime $\Gamma$-ring.

The control performances for active re-reflecting wave control suggested in the previous paper have been verified in cases of regular and irregular waves in a real two dimensional wave basin. For regular waves, the control performances are investigated in terms of reflection coefficients, expected amplitudes of propagating waves and wave absorbing capabilities after cessation of wave generation, compared with those of no-control cases. For irregular waves similar verification procedures were adopted. Though there are certain constraints due to the geometrical non-linearity of wave maker and certain nonlinear characteristics due to the near field and gravity waves these experiments show that the control logic could be useful in realizing re-reflecting wave control in conditions of real wave basin.

Purpose: The purpose of this study was to explore how public health nurses (PHNs) perceive their roles and duties (R&D), as well as to investigate the change of their R&D, how they manage and solve problems. Methods: The data were collected through focus group interviews. Data were analyzed using Morgan (1998) and Krueger (1998)'s four step analysis. A total of 17 experienced PHNs participated in this study. Results: The results found 5 themes and 19 sub-themes: R&D of health managers and health service providers, factors affecting the changes of PHN's R&D, R&D in adjusting with trends and expanding work field (R&D being reduced, increasing R&D, need to expand R&D), problem with the structure and quality of workforce (lack of nurse manpower, lack of promotion opportunities, increasing non-regular workers, lack of refinement as an expert), and strategies for solving personnel issues (strengthening the job capacity, cultivating professional refinement, strengthening outside activities and political activities, strengthening the roles of PHN-related associations and academy, engagement policy of non-regular workers, expansion of the activity area) Conclusion: PHNs need to recognize their changing R&D and ways they manage and solve problems to enhance their professionalism.
