We propose a new data carousel scheduling algorithm for on-demand data broadcasting in DMB. The server divides data items into two sets named hot and cold, according to request statistics from clients. When constructing a data carousel, hot items are placed periodically with their upper limit of broadcasting frequency. If there are empty slots after placing hot items, cold items with high request ratio are placed until the carousel is full. A cold item is broadcast only once in the caroulsel. For the response on clients' requests, our proposed scheme is shown to have high success ratio with short waiting time.

This paper deals with the development of an intelligent CAD system for specifying the operation sequence in cold forging. Cold forging technology is facing with various new design requirements. Therefore, it is very important to develop a decision method for the operation sequence, with comparatively high adaptability to the new requirements. An intelligent CAD system which is the uncertain factors in human knowledge into consideration by applying fuzzy theory is established. Various actual design data about were organized, and these organized data were applied to the system as the case base. The system automatically generates the design data of operation sequence such as the forming method and the geometric data of products in each operation stage by the reasoning method applied the fuzzy pattern matching. By comparing the design results in the above system with the actual design data of a human expert, this paper presents that our method is useful for practical application.

Objectives: Facial diagnosis is an important part of clinical diagnosis in traditional East Asian Medicine. In this paper, using a fully automated facial shape analysis system, we show that facial morphological features are associated with cold pattern. Methods: The facial morphological features calculated from 68 facial landmarks included the angles, areas, and distances between the landmark points of each part of the face. Cold pattern severity was determined using a questionnaire and the cold pattern scores (CPS) were used for analysis. The association between facial features and CPS was calculated using Pearson's correlation coefficient and partial correlation coefficients. Results: The upper chin width and the lower chin width were negatively associated with CPS. The distance from the center point to the middle jaw and the distance from the center point to the lower jaw were negatively associated with CPS. The angle of the face outline near the ear and the angle of the chin line were positively associated with CPS. The area of the upper part of the face and the area of the face except the sensory organs were negatively associated with CPS. The number of facial morphological features that exhibited a statistically significant correlation with CPS was 37 (unadjusted). Conclusions: In this study of a Korean population, subjects with a high CPS had a more pointed chin, longer face, more angular jaw, higher eyes, and more upward corners of the mouth, and their facial sensory organs were relatively widespread.

This clinical study is designed to find the characteristics of heat and cold according to Sasang Constitutions by using a statistical analysis. The study was conducted based on the questionnaire sheets and medical history (clinical data) of 1080 people registered at Sasang Constitution Information Bank (SCIB). The total number of people registered at SCIB was 1083; however, 3 Taeyangin's data were excluded in this study. The statistical analyses results on these data were: Most Taeumins have warm limbs, while Soeumins have cold ones. Taeumin, and Soyangin do not like hot weather, while Soyumin doesn't like coldness. As soeumins' body temperature is relatively lower than that of other constitutions, they tend to sleep tightly under blankets or comforters. Taeumin tend to drink more water because they sweat a lot; while Soeumin drink smaller amount of water because they sweat less. Both Taeumin, and Soyangin like cold food, but Soeumin liked hot food. Soeumin showed strong tendency for hot and cold food, while other constitutions displayed less inclination toward the certain temperature of food. Soeumin certainly had the remarkable response toward changes in heat and cold than other constitutions. The differences written above were proved to be meaningful enough by Chi-square test.

This study was to analyse the eating out behaviors of customers who visit a Koran restaurant especially focused on CNR(cold noodle: naengmyun restaurant) and to find out the marketing promotion points. Through the snowball sampling, 423 customers data were surveyed in summer and winter as respects of seasonal variation. The collecting data were analysed descriptive data and statistical different using the Statistical Package for the Social Science(SPSS version 10.0). The results were as follows; The participants of the study were composed of 209 man(49.4%) and 204 woman(50.6%). Most customers were 30's(36.2%), office worker(27.5%) and spend 5,000${\sim}$10,000 won(46.3%) for eating out. The consumer more preferred a specialty restaurant, the reason was to expect better taste(37.1%). In visiting CNR, the customer frequently ordered complement menu(90.1%) with cold noodle, complement menu should be developed periodically. The important factor to visiting CNR was the accessing convenience for the shop and desirable taking time was within 15 minutes. The buckwheat noodle in broth(mulnaengmyun) was the most favorite selecting menu. And the noodle texture was key evaluation factor in all types of cold noodle and the other factor was different according to the types of cold noodle. The visiting frequencies of CNR were not significantly different according to seasonal variation and sociodemographic variable. Above the half of customers visited at CNR with his/her family. This study find out the suggestion that consumer eating concepts about CNR was family eating therefore the cold noodle. specialty restaurant should be create more delight atmosphere and developed menu for families' eating out place.

Near-net-shape forming of zirconia powder was investigated under the combination of cold die and isostatic pressing and pressureless sintering. A novel combination pressing technique, i.e., die com paction under cold isostatic pressing, allowed to produce a complex shaped ceramic powder compact with the controlled dimensions and relatively uniform density distributions. The constitutive models proposed by Kim and co-workers for densification of ceramic powder under cold compaction and high temperature were implemented into a finite element program (ABAQUS). Experimental data for relative density distributions and deformations of zirconia powder compacts produced by cold combination pressing and pressureless sintering were compared with finite element results. Finite element results agreed well with experimental data.

Most cold-adapted enzymes possess higher $K_m$ and $k_{cat}$ values than those of their mesophilic counterparts to maximize the reaction rate. This characteristic is often ascribed to a high structural flexibility and improved dynamics in the active site. However, this may be less convincing to cold-adapted metabolic enzymes, which work at substrate concentrations near $K_m$. In this respect, cold adaptation of a shikimate kinase (SK) in the shikimate pathway from psychrophilic Colwellia psychrerythraea (CpSK) was characterized by comparing it with a mesophilic Escherichia coli homolog (EcSK). The optimum temperatures for CpSK and EcSK activity were approximately $30^{\circ}C$ and $40^{\circ}C$, respectively. The melting points were $33^{\circ}C$ and $45^{\circ}C$ for CpSK and EcSK, respectively. The ${\Delta}G_{H_2O}$ (denaturation in the absence of denaturing agent) values were 3.94 and 5.74 kcal/mol for CpSK and EcSK, respectively. These results indicated that CpSK was a cold-adapted enzyme. However, contrary to typical kinetic data, CpSK had a lower $K_m$ for its substrate shikimate than most mesophilic SKs, and the $k_{cat}$ was not increased. This observation suggested that CpSK may have evolved to exhibit increased substrate affinity at low intracellular concentrations of shikimate in the cold environment. Sequence analysis and homology modeling also showed that some important salt bridges were lost in CpSK, and higher Arg residues around critical Arg 140 seemed to increase flexibility for catalysis. Taken together, these data demonstrate that CpSK exhibits characteristics of cold adaptation with unusual kinetic parameters, which may provide important insights into the cold adaptation of metabolic enzymes.

The estimation of reasonable amount of domestic cold water and hot water supplies in apartment houses is very important for the economical design of domestic cold water and hot water supply system which include pumps, boilers, heat exchangers, and various water reservoirs. To suggest the model of predicting reasonable amount of domestic cold water and hot water supplies, residents and actual domestic cold water and hot water consumption have been investigated for 740 apartment houses in Seoul and Bun-Dang, Kyunggi-Do. The model is suggested as a function of exclusive area of the apartment house and results of the model show generally good agreement with published data.
