As the range of the customer choice becomes more diverse, the average life span of companies' products and services is becoming shorter. Most companies are striving to maximize the revenue by understanding the customer's needs and providing customized products and services. However, companies had to bear a significant burden, in terms of the time and cost involved in the process of determining each individual customer's needs. Therefore, an alternative method is employed that involves grouping the customers into different categories based on certain criteria and establishing a marketing strategy tailored for each group. In this way, customer segmentation and customer clustering are performed using demographic information and behavioral information. Demographic information included sex, age, income level, and etc., while behavioral information was usually identified indirectly through customers' purchase history and search history. However, there is a limitation regarding companies' customer behavioral information, because the information is usually obtained through the limited data provided by a customer on a company's website. This is because the pattern indicated when a customer accesses a particular site might not be representative of the general tendency of that customer. Therefore, in this study, rather than the pattern indicated through a particular site, a customer's interest is identified using that customer's access record pertaining to external news. Hence, by utilizing this method, we proposed a methodology to perform customer segmentation. In addition, by extracting the main issues through a topic analysis covering approximately 3,000 Internet news articles, the actual experiment applying customer segmentation is performed and the applicability of the proposed methodology is analyzed.

Purpose: This study is designed to analyse etiology and bone pattern at the first visit using cone-beam computed tomography (CBCT) and to evaluate the treatment outcome of conservative treatment in temporomandibular disorder (TMD) patients with rheumatoid arthritis (RA). Methods: One hundred condyles in 50 subjects with RA were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Dental Hospital, diagnosed as TMD. Condylar bone changes were classified by normal, erosive bony change, proliferative bony change and combined group (erosive bony change+proliferative bony change). They were treated conservatively with physical therapy, medication, behavioral therapy and/or occlusal stabilizing splint therapy. After 3 months on average, patients were re-evaluated with regards to subjective symptoms and the clinical findings were investigated. Results: TMD patients with RA have behavioral contributing factors such as parafunctional habit. The results that analyse bone pattern at the first visit using CBCT proliferative bony changes group (32.6%) were more common than erosive bony changes group (15.2%). In comparison between unilateral and bilateral bony change in temporomandibular joint, the ratio showed no significant differences. After 3 months of conservative treatments, pain, noise, limitation of motion (LOM) were markedly improved regardless of occlusal splint therapy. However only LOM was significantly improved through occlusal splint therapy during 3 months. Conclusions: TMD patients with RA had similar behavioral contributing factors and characteristics of CBCT images shown in general TMD patients and also similar response to conservative treatment so it is difficult to differentiate. Therefore when TMD patients show symptoms corresponding to clinical diagnostic criteria of RA at the first visit, serological testing should be conducted and through this, early diagnosis and treatment of RA should be initiated.

The purpose of this article is to provide a method of losing weight and early managing risky factors of geriatric diseases by having male and female obese middle school students' participate in behavioral modification and aerobic exercise, foster their own desirable behavioral habit and confidence in solving obesity and continue their living pattern all their life. In order to do this, 64, subjects over 20% obese degree obtained using the standard weight, belonging within 50% range of weight percentage per height(male:32, female:32) were grouped to 4 categories of aerobic exercise therapy, behavioral modification therapy, both therapies combinedly applied and control ones by 8 male and female students allocated to each group respectively, and they were practiced to each program for 12 weeks, and the findings between group were obtained as follows. 1. The male and female middle school students' cholesterol amount of blood fat reduced most in the combinedly performed group of aerobic exercise and behavioral modification therapy. It indicated a statistically significant difference between groups (F(3,56) =9.50, p=.000) and the measurements according to the application period of program as well (F(3,168)=554.94, p=.000). The cholesterol amount per measurement period reduced most between 8 and 12 weeks. 2. The male and female middle school students' high density fat amount increased most in the combinedly performed group of aerobic exercise therapy and behavioral therapy, its descending order of next highest rate was aerobic exercise therapy, behavioral modification therapy and control group. It indicated a statistically significant difference between the distinction of male and female sexes (F(1.56)=13.82. p=.000) and the measurements according to the application period of program (F(3,168) =55.58, p=.000). The high density fatty Quality per measurement period increased most between 8 and 12 weeks. 3. The male and female middle school students' low density fat amount reduced most in the combinedly performed group of aerobic exercise therapy and behavioral modification therapy. It indicated a statistically significant difference between groups (F(3,56)=17.35, p=.000) and the measurements according to the application period of program (F(3,168)=891.14, p=.000. The low density fat amount reduced most between 8 and 12 weeks. 4. The male and female middle school students' neutral fat amount reduced most in the combinedly performed group of aerobic exercise therapy and behavioral modification therapy. It indicated a statistically significant difference between the distinction of sexes (F(1,56)=9.54, p=.003) and groups (F(3,56) =25.57, p=.000) and the measurements according to the application period of program (F(3,168) =566.03, p=.000). The male students indicated the most reduction between 4 and 8 weeks. while the female students between 8 and 12 weeks.

Behavioral response to a diel photoperiodicity (500 lx for 16 h, 5 lx for 4 h and < 0.5 lx for 4 h) and phototactic characteristics in dark conditions were examined with Siberian sturgeon Acipenser baerii (Chondrostei, Actinopterygii) prelarvae. Siberian sturgeon prelarvae represented both qualitative and quantitative changes in their behavioral patterns according to different light intensities in a diel photoperiodicity. Under daylight conditions (500 lx), prelarvae displayed saltatory changes of behavioral features with ages (Day 0-Day 9) in a general order of swimming-up/drifting, swimming in the upper water column, benthic swimming with rheotaxis, schooling and post-schooling behavior. Compared to daylight conditions, prelarvae tended to show more benthic performances and quantitative reductions of schooling and post-schooling behaviors under dimlight conditions (5 lx). Under dark conditions (< 0.5 lx), prelarvae exhibited a fairly uniform behavioral pattern characterized by the benthic swimming across the bottom of the tank. From phototaxis tests under dark conditions, navigational responses of prelarvae to a spotlight illumination were quantitatively changed as their ages increased. The phototactic responses reached the peak on Day 2, continued until Day 4, and then gradually decreased until Day 8. A partial recovery of positive phototaxis was observed on Day 9. Data from this study suggest that the diel light cycle as well as the light intensity of each interval in the cycle should be considered as important components of a practical guide for evaluating fitness and developmental states of artificially propagated Siberian sturgeon prelarvae.

Objectives: Externalized behavioral problems are prevalent in adolescents, due to the difficulties associated with this developmental stage. Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD), as well as other psychiatric disorders, such as major depressive disorder, result in the manifestation of many behavioral problems during adolescence. Methods: For this report, we analyzed a sample of 31 adolescents, each of whom had presented with CD or ODD at Chosun University Hospital between 2002 and 2010. We separated subjects into depressed and non-depressed groups according to their Beck Depression Inventory scores (BDI<10, non-depressed ; BDI${\geq}$10, depressed). Then we analyzed for neuropsychological differences between the depressed and non-depressed groups. Results: In our sample, adolescents in the depressed group showed less of a stealing (deceitfulness and/or theft) behavioral pattern and presented with more anxiety symptoms, lower self-esteem, and greater sensitivity in interpersonal relationships, as compared to the non-depressed group. Conclusion: When adolescents exhibit disruptive behavior, clinicians should consider the underlying causes of the behavior.

The purpose of this study was to provide basic data on preschool children for accident prevention and to improve their health through a sound, safe living environment with safety education established through more systematic methods. Data were collected from 516 preschoolers from 4 to 6 years old using APP paper test which consists of a question and drawing. The children's general characteristics and accident proneness prospect were investigated. The relationship between the children's general characteristics and the accident proneness prospect were analyzed. The findings of the study are as follows : 1. The institution which children attended had a significant difference in accordance with the living safety (p=.015) and behavioral character(p=.033). 2. The housing pattern in which children lived had a significant difference in accordance with the movement speed(p=.027). 3. The children's age had a significant difference in accordance with the living safety(p=.002), traffic safety(p=.001), the reasoning power(p=.000), movement speed(p=.00), movement stability(p=.000) and attentional power(p=.000). 4. The children's sex had a significant difference in accordance with the movement stability and behavioral character (p=.003, p=.008). 5. The children's past accidental experience had a significant difference in accordance with the behavioral character(p=.001). 6. General assessment of the APP test had a significant difference in accordance with the children's age(p=.000) and children's past accidental experience(p=.020).

The purpose of this study was to examine the mother's perception on the concrete pattern of such behavior problems as noncompliance, jealousy, dependency, hyperactivity and stealing, by analyzing the difference between two cases of her own child and another mother's child relating to her attribution to the behavior problem of the child and the relationship between her attribution and behavioral reaction. This study was carried out by using 515 questionnaires answered by 1000 mothers of children of 7 kindergartens in Ulsan and Taegu, using Melissa Sweitzer's method (1986). The data was subjected to t-test, Pearson's correlation coefficient. T-test was applied to test the difference between two cases of her own child and another mother's child relating to her attribution to the behavior problem of the child and Person's correlation coefficient was estimated to test the relationship between her attribution and behavioral reaction. The result of this study is sumarized as follows : 1. It was shown that the mother's attribution to the behavior problem of the child is less serious when her child showed the behavior problem than when another child dose the problem while her attribution has an affective reaction to the behavior problem of the child. 2. The relationship between the mother's attribution and behavior reaction to the behavior problem of the child appeared variously in accordance with the attribution factor and behavior problem. Then the mother showed more attribution to stability while frequently ignoring the child.
