그리드 자원 관리는 지리적 분산과 이 기종 컴퓨팅 자원의 활용 그리고 인터넷 웹 환경에 주안점을 두고 설계되어야 한다. 이를 위해서 기존 부분기능 위주의 모델을 포괄하면서도 전체적인 상호협력 동작에 기반한 3개 기본요소와 8기관의 그리드 자원 관리 모델을 제시한다. 이를 통해 전체적인 관점에서 그리드 자원관리를 평가할 수 있는 G값을 살펴보고, G값을 기준으로 하여 최적의 그리드 자원관리 방안을 모델링 한다.

The structural models of plan fabric were set up such as sinusoidal curve, alternate semicircle, alternate elliptical shape, and derived square cloth. Each model was analyzed theoretically and the relationship between β-ratio and maximum crimp factor was studied as following: Model Ⅰ, Sinusoidal curve ; C = { π(1+β)/4β+2π}2 Model Ⅱ, Alternate semicircle ; C=0.57(const.) Model Ⅲ, Alternate elliptical shape ; C= π√1+ζ2/2√2 -1 Mpdel Ⅳ, Derived square cloth ; C=cos-1 β/1+β/sin(cos-1 β/1+β) -1 where C stands for crimp factor. Nomenclature β; ratio of warp diameter to filling diameter ζ; aspect ratio(=b*/a*) θ; angle of position vector i ; unit vector in the x-direction j ; unit vector in the y-direction r ; position vector a ; max. distance between the center line of fabric and the center line of thread a*; distance between the center of filling and the center of warp along the fabric center line b*; distance between the center of filling and the center of warp normal to the fabric center line. C; (max.) crimp factor d ; diameter of thread df; diameter of filling dw; diameter of warp k ; √b*2-a*2/b* l ; thread (warp) length in the spacing p. L; length of curve p; thread (filling) spacing x, y; Cartesian coordinates.

When marketing in the true meaning was introduced in hotel industry is supposed to be in the 1980's. The importance of promotion mix is emphasized to make the best use of marketing activities, and this field is what we must be mostly concerned about specially in current situation of keen competition in hotel industry. This study examined variety of sales promotion activities, practicable in hotel enterprise where such activities should have function of communication to dice information to purchasers, a major function of problem, and then to convince and induce them to purchase finally, and also suggested some measures to check problems raised in the course of sales promotion activities and to perform such activities effectively. Types of sales promotion in hotel industry are classified in various ways according scholars, but this study explained them dividing into two typs, Special Communication Method suggested by Dommermuth, and Special Offer Method, Firstly, Special Communication Method is a general term for methods for hotel enterprise to promote sales by way of latent customers and travel agencies selling for them, and it is applied to communicate with latent customers and travel agencies, intermediaries, Dignitas Methods are, 1) House Organs 2) Sampling 3) P. O. P (Point of Purchase) 4) Dealer Contest 5) Every kinds of announcement and invites of exhibition 6) Dealer helps 7) Advertising Speciality 8) D. M. 9) Bill Secondly, Special Offer Method is a general term for all methods repeated and short-run to induce customers to purchase as often as possible. Dignitas Methods are 1) Rebate 2) Recognition Programs 3) A gift 4) Coupons 5) Price-Offs 6) Premiums 7) Contest & Sweeptakes 8) Continuity Programs. Comparing merits and demerits of each method, you must select your own method of sales promotion with close consideration on conditions of your own hotel business, and constant observation of sales promotion activities of your rival hotel enterprises.
