"A smile is happiness you'll find right under your nose"- Tom Wilson. This quote holds true just for patients, not for surgeons. The correction of the nose always poses a challenge to the cosmetic surgeon. Deformities of the external and internal nose may be congenital or acquired and may be secondary to soft tissue and/or osseo-cartilaginous abnormalities, leading to aesthetic and/or functional consequences. Alar flare poses a common problem, sometimes alone and sometimes in conjunction with other external deformities. Alar base reduction is generally considered when the interalar distance exceeds the intercanthal distance. It has been well documented that this simple additional procedure brings about a substantial enhancement in the nose. Various techniques have been described and used in the past, each having their benefits and drawbacks, with the modified Weir wedge excision, Aufricht nasal sill excision, and Bernstein V-Y advancement being the common ones. We hereby describe a technique that is simple yet effective in achieving the desired results and at the same time aims at preventing relapse to obtain satisfactory long term results.

To enhance our understanding of toxicity mediated through the pathway by which TCDD stimulates gene expression, we have investigated genes whose expressions are changed after treatment with TCDD and/or MNNG in human Chang liver cell. First, we treated with MNNG and TCDD for two weeks to transform human Chang liver cell. We obtained cell looks like to be transformed and compared the differential gene expression by using cDNA chip (Macrogen) which carrys genes related with signal transduction pathways, oncogenes and tumor suppressor genes, etc. We found that TCDD up- or down-regulated 203 and 111 genes including oncogenes and tumor suppressor genes in human Chang liver cell two fold or more, respectively. Second, we compared the differential gene expression after treatment with TCDD only by using cDNA chip (Superarray) which carrys genes related with cell cycle regulations, and found that TCDD up regulated genes related with cell proliferation as well as cell growth inhibition in human Chang liver cell two fold or more, respectively. These results suggest that toxicity induced by TCDD may reflect sustained alterations in the expression of many genes and that the changes reflect both direct and indirect effects of TCDD.

The society, nowadays, is in a state of transition, and the family, which must always accomodate to society, is change with it. And because of transitional difficulties , the family's major psycosocial task has become more important than ever. That is , the family sill change. but it will aso reamin because it is the best human unit for rapidly changing societies. Under the circumstances, a healthy marital interaction is still the key to optimal family process, and the marital relationship is also the basis of the parental one. This paper aims to study an conceptual schema of family functioning chiefly concerned with marital relationship base d ton the family therapeutic psychology the systematic approaches of which have been recently developed. Subsequent to the importance of spouse functions and the characteristic of a functioning family the marital tension as a cause of marital problems and the theoretical approaches that will allow to deal with these problem , are also explained in this paper. On the otherhand, the sexual dysfunction, one aspect of a wider set of marital problems, and problems of dysfunctional children are not discussed in detail , because these problems shall become specialized fields. By this paper , it is expected to find a clue to the emotional and psycosocial aspects of marital problems, which will help us have a broader viewpoint in the study of family relationship.

This study investigated the characteristics of baking bread and cookies supplemented with taurine and the effect of taurine addition on BAC(blood alcohol concentrations) and UAC(urine alcohol concentrations). Healthy male college students were divided into two groups, the control and the taurine group. Bread was baked with the addition of 0, 2, 4 and 6% taurine and baked with the addition 0, 3 and 6% taurine. The bread containing 2% taurine showed the fastest fermentation among the 4 groups. Fermentation and oven-spring of breads baked with a taurine concentration greater than 4% of taurine disturbed. In some areas of the sensory test, the taurine supplemented bread had higher scores than the control bread. We served 6 g of taurine supplemented cookies with 1,000 $m{\ell}$ of beer to 8 students in the taurine group. After 2 hours of drinking beer, the BAC and UAC of the taurine group were found to be lower than the control group. But no difference was found in the alcohol excretion of their urine. From this study we concluded that the taurine has an effect on the detoxication of alcohol, which reduces the BAC.

A toe spring and ball girth data, when marathone shoes research, development, and production in Korea, is a important point in athlete shoe research. It is clear from the results presented that any differences between MA3 and MA1, MA4 in 70%, 80% session in forepart last comparision. Especially the more 70%-80% session getting wide, the more 90% session getting up, Also, To development for high performance marathones shoes last, in all session, in korean style, 70%, 80%, and 90% session part function changed and consequently there is a need for normative last data that desribe foot, last shape, dimension. this leads to the conclusion that unique shoe lasts for both marathone shoes developmented last comparison are required for optimal marathone shoe comfort. The more ball girth construction will wide in forepart in last, the more comfort characteristic sill development. But relative with performance ability, it is need to research. The further study of Korea marathoner forefoot measurements(70% session ~ 90% session) among toe spring's angular difference of marathone last to north american and Korea marathone shoes last is required to develop and improve athletes performance in an effective way of study and to prevent forefoot injury.

Purpose: The purpose of this study was to find the factors influencing adolescents' adult media engagement. The study is based on Agnew's General Strain Theory (GST) and a micro-systemic perspective. Methods: The study examined 479 middle school freshmen who participated in the fourth wave of the Korean Children & Youth Panel Survey (KCYPS) conducted by National Youth Policy Institute. Data were analyzed through descriptive statistics, factor analysis, and reliability analysis using SPSS 22.0 Ver. Also, hypothesis testing was performed via covariance-based structure equation modeling (CB-SEM) using Amos 21.0 Ver. Results: Strain factors had positive effects on adolescent depression, and depression had a positive effect on adult media engagement. Also, cell-phone dependency had a positive mediation effect between depression and adult media engagement. Conclusion: The study's result identified the factors affecting adult media engagement. Therefore, we suggest intervention programs considering adolescents' strains, depression and cell-phone dependency to improve their health.

This investigation is the result of a structural analysis by the finite element method and static loading test for the optimal structural design of an electric railway vehicle made of stainless 301L materials. We analyzed the stress and displacement of the existing electric car-body structure for predicting the position of concentrated stress, the flow of stress, rigidity to be occurred in the car-body structure when it is subjected to the vertical load. It was exposed that the side sills and window corners around the bolsters are the weak parts of the electric car-body structure because the bolsters of the electric car-body structure were subjected to the vertical load and dynamic load to be occurred during running. The flow of stress and the cause of stress concentration in the weak zone were studied in order to prevent the concentration of stress and buckling. The rearrangement of the structure and the selection of the beam elements were also carried out for optimum design of the structure.

Getting on and off an elevator is one of the most important parts for multi-floor navigation of a mobile robot. In this study, we proposed the method for the pose recognition of elevator doors, safe path planning, and motion estimation of a robot using RGB-D sensors in order to safely get on and off the elevator. The accurate pose of the elevator doors is recognized using a particle filter algorithm. After the elevator door is open, the robot builds an occupancy grid map including the internal environments of the elevator to generate a safe path. The safe path prevents collision with obstacles in the elevator. While the robot gets on and off the elevator, the robot uses the optical flow algorithm of the floor image to detect the state that the robot cannot move due to an elevator door sill. The experimental results in various experiments show that the proposed method enables the robot to get on and off the elevator safely.
