One faces four major developmental tasks to achieve in young adulthood, ages between 20 and 40 : intimacy, vocation, marriage and child-rearing. Intimacy is the capacity to commit oneself to concrete affiliations and partnerships and to develop the ethical strength to abide by such commitments, even though they call for significant sacrifices and compromises. Through vocation and marriage young adults become united to networks of persons, find tasks that demand involvement, and gain roles into which they fit and are fitted and which help define their identities. An occupation represents much more than a set of skills and functions : it means a way of life. The extent of vocational choice increases with educational level, and the unconscious factors are frequency the decisive element. The vocational choice stare with fantasy choices in childhood, passes through tentative choices in adolescence, realistic choices in college days, and crystallized choices in post-college days, and finally ends up to the choice of specification. Along with the hazards and the need for realignment of personality functioning, the marriage brings with it new opportunities for self-fulfillment and completion. Motives other than a romantic love gain more importance in the decision to marry and in the choice of a partner. The impulsions to marry are sexual gratification, the desire to propagate, narcissistic gratification, and a need of interdependence. Many factors such as oedipal wishes, sexuality and sexual attractions, socio-economic classes, and geography involve in selection of marriage partner. There are also various motivations to marry a romantic love, the desire for a home of one's own, sexual attractions, the wish for security and a shelter, and the wish for children. The hostile marriage, the marriage on the rebound, the marriage rooted in rescue fantasies, and sado-masochistic marriage are the examples of pathological marriages. A successful marriage will usually both Lead to and require a marked reorganization of the personality structure of each partner that will influence the lurker personality development of each. Many marital problems are largely dependent upon the personality characteristics of one partner which might well create difficulties no manor who was the spouse.

The realistic modeling of the beam-column semi-rigid connection in steel frames attracted the attention of many researchers in the past for the seismic analysis of semi-rigid frames. Comparatively less studies have been made to investigate the behavior of steel frames with semi-rigid connections under different types of earthquake. Herein, the seismic behavior of semi-rigid steel frames is investigated under both far and near-field earthquakes. The semi-rigid connection is modeled by the multilinear plastic link element consisting of rotational springs. The kinematic hysteresis model is used to define the dynamic behavior of the rotational spring, describing the nonlinearity of the semi-rigid connection as defined in SAP2000. The nonlinear time history analysis (NTHA) is performed to obtain response time histories of the frame under scaled earthquakes at three PGA levels denoting the low, medium and high-level earthquakes. The other important parameters varied are the stiffness and strength parameters of the connections, defining the degree of semi-rigidity. For studying the behavior of the semi-rigid frame, a large number of seismic demand parameters are considered. The benchmark for comparison is taken as those of the corresponding rigid frame. Two different frames, namely, a five-story frame and a ten-story frame are considered as the numerical examples. It is shown that semi-rigid frames prove to be effective and beneficial in resisting the seismic forces for near-field earthquakes (PGA ≈ 0.2g), especially in reducing the base shear to a considerable extent for the moderate level of earthquake. Further, the semi-rigid frame with a relatively weaker beam and less connection stiffness may withstand a moderately strong earthquake without having much damage in the beams.
It is sometimes said lately that the pH of the human gastric juice is significantly different among individuals. Thus, the dissolution behavior of coated solid dosage forms should preferably be independent of the pH of the test solution. With these points as a background, the effect of pH on the dissolution velocity of coated tablets was studied to compare that of Pharmacoat with other gastric soluble film coating materials. Three viscosity types of Pharmacoat have been available(3, 6 and 15cP) until now. the 6cP type has been considered to be the most suitable for a tablet coating amongst the three types. The 3 cP type with a low degree of polymerization, is capable of providing high concentration, but the film strength is so inferior that sometimes cracking of the film may occur. On the other hand, in the case of the 15cP type, high polymer concentration cannot be achieved because of the high dgree of polymerization, and thus it is uneconomical for coating. Now, there is a strong demand to reduce the coating time even when HPMC is used in the 6cP type in order to reduce the coating cost. In order to improve this problem, we have concentrated our attention on reducing the viscosity value of HPMC to an allowable lower limit from 6cP. As a result of this study, it was found that the reduction of the viscosity value to around 4.5cP enabled the use of a higher solution concentration and an incidental shorter coating time without giving any substantial adverse effects on the properties of coated preparations. These experiment results are presented in the later part of this presentation. Based on this study, we have added the viscosity type of 4.5cP as one of the Pharmacoat products as Pharmacoat-645.
As we enter an era of emotional and endlessly competitive society, there has been a lot of changes happening to the styles and images of men, traditionally associated with strength and power. Today, the media is giving information on today's trendy men's styles and images to meet the growing demand by consumers, and giving appropriate gains in the process to all - both information providers and consumers. Generally speaking, the cover of a magazine represents the concept and image of the magazine. The cover model is closely tied with the symbolic image of the magazine, the current times, and what the general public wants. Therefore, research on the cover models of a lifestyle magazine has significance in that the current style trends will be able to be understood directly. The present research investigated the sexual images of men's magazine cover models. In carrying out the research, the sexual images were classified into the following: homosexual, cross sexual, metro sexual, and uber sexual. The research findings showed that uber sexual is the dominant sexual image in men's magazines in Korea, followed by metro sexual. In conclusion, the findings suggest an expansion of the traditional image of men, happening with the changes in traditional sex roles.

This study aims to examine the existing conditions of elderly housing facilities and to understand the characteristics and types of outdoor living environments utilized by the elderly. To achieve this, this study relied on two methods: a descriptive method of researching publications and related scholastic writings, and an empirical study that included a survey of present conditions and interviews with the elderly and their nursing care providers. Additionally, evaluation of usage patterns and physical traces were carried out in twelve cases. First, the study showed that all of the facilities, which are fixed in particular areas, had difficulty providing spatial diversity that met the needs of residences. This means that these areas lack flexibility. Activity programs were, however, carried out in a lively manner in well-equipped spaces. Second, an evaluation of outdoor living environments showed that basic facilities were more than adequate, in general. Consideration of resident's physical strength and taste, however, was evaluated as low, indicating that facilities and spaces should be considered to reflect the ages, physical capacity, diverse tastes and hobbies of the elderly, as well. Third, examining the usage patterns of outdoor living activities of residents, the purposes of using outdoor spaces of elderly housing facilities were mainly 'to take a walk' and 'to engage in simple physical exercise' and the walkway, simple sports facilities, and building entrances were highly utilized. The importance of outdoor living environments values was a mean of 4.07 and satisfaction was 4.17. This indicates that residents thought that outdoor living environments are very important and currently satisfied with them.

Recently, in order to satisfy the consumer's demand the life cycle and the lead-time of a product is to be shortened. It is thus important to reduce the time and cost in manufacturing trial products. Several techniques have been developed and successfully commercialized in the market RPM(Rapid Prototyping and Manufacturing). However, most commercial systems currently use resins or waxes as the raw materials. So, the limited mechanical strength for functional testing is regarded as an obstacle towards broader application of rapid prototyping techniques. To overcome this problems, high-speed machining technology is being investigated worldwide for rapid manufacturing and even for direct rapid tooling application. In this paper, some fundamental experiments and analyses are carried out to obtain the filling time, materials, method, and process parameters for HisRP process. HisRP is a combination process using high-speed machining technology with automatic filling. In filling process, Bi58-Sn alloy is chosen because of the properties of los-melting point, low coefficient of thermal expansion and enviromental friendship. Also the use of filling wire is of advantage in term of simple and flexible mechanism. Then the rapid manufacturing product, for example a skull, is machined for aluminum material by HisRP process with an automatic set-up device of 4-faces machining.
Studies related to water quality in catfish ponds were conducted on commercial catfish production ponds and compared with its receiving streams' water quality in central and west-central Alabama. The ponds were stocked with 10,000 fish/ha. The ponds were aerated nightly (0000-0600 hrs). Fish were fed to satiation at about the same time, six-days a week. In order to assess the pollutional strength of effluents from commercial channel catfish ponds, water samples were collected during each calender season from fall 1990 through summer 1991, and selected water quality variables were monitored. Mean values for water temperature, dissolved oxygen concentration, pH, settleable solids, total suspended soilds, volatile solids, total phosphorus, soluble reactive phosphate, biochemical oxygen demand, total ammonia nitrogen, nitrite, nitrate, and total Kjeldahl nitrogen were basically the same (P> 0.05) between samples taken from the surface and near the bottom. Concentrations of most water quality variables of catfish ponds were higher than those of receiving streams, and especially it had much higher average concentrations of nitrogen and phosphorus than streams.

Small area estimation is becoming important in survey sampling due to a growing demand for reliable small area statistics. In estimating means, totals, and other parameters for small areas of a finite population, samplie sizes for small areas are typically small because the overall sample size is usually determined to provide specific accuracy at a much higher level of aggregation than that of small area. The usual direct estimators that use the only information which is gotten from the sample in a given small area provide unreliable estimates. However, indirect estimators utilize the information from the areas related with a given small area, that is, borrow strength from other related areas, and so give more accurate estimates than direct estimators. In this paper we investigate small area estimation methods such as synthetic, composite and empirical best linear unbiased prediction estimator, and apply them to real domestic data which is from the Survey of Hotels and Restaurants in In-Chon as of 1996 and then evaluate the performance of these methods by measuring average squared errors. This evaluation shows that indirect estimators, which are small area estimation methods, are more efficient than direct estimator.

As a right-of-way security for the high power transmission line tower construction is becoming more and more difficult, the friendly environmental compact tower design is required. For a proper insulation for the compact tower, the polymer material are being tried. Some countries has already adapted, in the various polymer application and management data, polymer arm insulator to the transmission tower, and shown a stable operation. However, in our country, the polymer arm insulator has left much to be desired in the installation on the transmission line tower. But polymer material has been developed by high strength and technology and is expected to be used in various electric equipments. The polymer arm insulator is a one of good electric insulation materials to expand the power supply capacity in the rapid power demand increasement In this research, the new polymer am insulator is designed and its electric specifications are analyzed. Its mechanical specifications is verified through the field test on the compact tower which is modified by the polymer arm insulator.

Most land development projects and large scale civil works require a great amount of sand. And sand is also the most favorable material for soft ground improvement. The demand for sand is soaring rapidly due to increased number of projects regardless of its limited supply. Therefore, it is not difficult to predict that sand may become depleted and no longer be available as ground improvement material in the near future. Against this backdrop, developing an inexpensive sand-substitution material with an efficient accessibility will be necessary and urgently called for. So quick lime could be recommended as the substitutional material for sand. Quick lime is now preferred by forward developed nations. If Korea is able to take advantage of its abundant supply, economical efficiency could be achieved through massive production as well as being able to take advantage of utilization of natural resources. In this respect the purpose of this paper was to estimate improvement effect of soft ground though in-situ construction of quick lime pile. In-situ construction was peformed in road construction site of soft clay and in this study quick lime from Dan-yang that was estimated prominently in aspect of engineering characteristics was used. Quick lime piles were installed by 1.5m, 2.0m, 3.0m spacing to confirm improvement effect according to spacing and installed piles are 0.4m in diameter, up to 5m in length and the density of quick piles installed is 1.4 t/㎥. Vibrating wire pore water pressure cell was installed to confirm consolidation characteristics in surrounding of quick lime piles and both laboratory test and field test were carried out to confirm strength increase. In conclusion, soft ground improvement by quick lime piles was confirmed.
