This paper presents a commonality and variability analysis method for UML CASE tool frameworks. Commonality and Variability analysis increase extension and reusability by separating common area and variable area. We suggest class category based on property and the notation to represent commonality and variability. It is also implements frameworks based on analysis method and verify method using defect removal efficiency.

Genome-wide association studies (GWAS) are designed to discover genetic variants such as single nucleotide polymorphisms (SNPs) that are associated with human complex traits. Although there is an increasing interest in the application of GWAS methodologies to population-based cohorts, many published GWAS have adopted a case-control design, which raise an issue related to a sampling bias of both case and control samples. Because of unequal selection probabilities between cases and controls, the samples are not representative of the population that they are purported to represent. Therefore, non-random sampling in case-control study can potentially lead to inconsistent and biased estimates of SNP-trait associations. In this paper, we proposed inverse-probability of sampling weights based on disease prevalence to eliminate a case-control sampling bias in estimation and testing for association between SNPs and quantitative traits. We apply the proposed method to a data from the Korea Association Resource project and show that the standard estimators applied to the weighted data yield unbiased estimates.

PURPOSES : This study is to evaluate the feasibility of using the alkali activated cement concrete for application of partial-depth repair in pavement. METHODS : This study analyzes the compressive strength of alkali activated cement mortar based on the changes in the amount/type/composition of binder(portland cement, fly ash, slag) and activator(NaOH, $Na_2SiO_3$, $Na_2CO_3$, $Na_2SO_4$). The mixture design is divided in case I of adding one kind-activator and case II of adding two kind-activators. RESULTS : The results of case I show that $Na_2SO_4$ based mixture has superior the long-term strength when compared to other mixtures, and that $Na_2CO_3$ based mixture has superior the early strength when compared to other mixtures. But the mixtures of case I is difficult to apply in the material for early-opening-to-traffic, because the strength of all mixtures isn't meet the criterion of traffic-opening. The results of case II show that NaOH-$Na_2SiO_3$ based mixtures has superior the early/long-term strength when compared to NaOH-$Na_2SiO_3$ based mixtures. In particular, the NaOH-$Na_2SiO_3$ based some mixtures turned out to pass the reference strength(1-day) of 21MPa as required for traffic-opening. CONCLUSIONS : With these results, it could be concluded that NaOH-$Na_2SiO_3$ based mixtures can be used as the material of pavement repair.

Objective : This case report aims to show the effect of Gamchogungang-tang, Hoiyeok-tang on an overactive bladder. The patient was diagnosed with Taeyang-byung based on Shanghanlun provisions. Methods : According to Diagnostic system based on Shanghanlun provisions, the patient was diagnosed with Taeyang-byung. So He was treated with Gamchogungang-tang, Hoiyeok-tang decoction for 70 days. We evaluated the results of treatment by Overactive Bladder Symptom Score(OBASS). Results : After taking Gamchogungang-tang, Hoiyeok-tang decoctions for 70 days, the patient's OBASS and symptoms was decreased from 12(severe) to 5(mile). Conclusions : This case report showed an effectiveness of using Gamchogungang-tang, Hoiyeok-tang according to Diagnostic system based on Shanghanlun provisions on overactive bladder.

Objective : This case report aims to show the effect of Osuyu-tang on an atopic dermatitis. The patient was diagnosed with Yangmyung-byung based on Shanghanlun provisions. Methods : According to Diagnostic system based on Shanghanlun provisions, the patient was diagnosed with Yanamyung-byung and has been unusual dietary habits. So she took Osuyu-tang decoction for 2 weeks. We evaluated the results of treatment by SCORAD Index and before and after treatment photos. Results : After taking Osuyu-tang decoction for 2weeks, the patient's SCORAD INDEX and symptoms was decreased from 49.5(severe) to 3.5(mile). Also, the patient's chronic diagestive disorder improved. Conclusions : This case report showed an effectiveness of using Osuyu-tang according to Diagnostic system based on Shanghanlun provisions on atopic dermatitis.

Objective : This case report aims to show the effect of Oryeong-san on dysmenorrhea. the patient was diagnosed with Taeyang-byung based on Shanghanlun provisions. Methods : According to Diagnostic system based on Shanghanlun provisions, the patient was diagnosed with Taeyang-byung and has over-worked since she had been sick. So she took Oryeong-san decoction for 1 month. We evaluated the results of treatment by Visual Analogue Scale and Moos Menstrual Questionnaire. Results : After taking Oryeong-san decoction for 1 month, the symptoms of patients improved. Conclusions : This case report sowed and effectiveness of using Oryeong-san according to Diagnostic system based on Shanghanlun provisions on dysmenorrhea.

Objective : This case report aims to show the effect of Bekhogainsam-tang on Overactive Bladder and Rheumatoid arthritis. The patient was diagnosed with Yangmyung-byung based on Shanghanlun provisions. Methods : According to Diagnostic system based on Shanghanlun provisions, the patient was diagnosed with Yangmyung-byng and has been unusual dietary habits. So she treated with Bekhogainsam-tang decoction for 75 days. We evaluated the results of treatment by Overactive Bladder Symptom Score(OABSS), Modified Overactive Bladder Validated 8-question Screener(OAB-V8), and Rheumatoid Arthritis Pain Score(RAPS). Results : After taking Bekhogainsam-tang decoction for 75 days, the patient's symptoms and OABSS was decreased from 20 to 11, OAB-V8 was from 42 to 20, and RAPS was from 130 to 63. Conclusions : This case report showed an effectiveness of using Bekhogainsam-tang according to Diagnositic system based on Shanghanlun provisions on Overactive Bladder and Rheumatoid Arthritis.

In this research, we suggest a Web-based hybrid recommendation mechanism using CBR (Case-Based Reasoning) and web data mining. Data mining is used as an efficient mechanism in reasoning for relationship between goods, customers' preference and future behavior. CBR systems are normally used in problems for which it is difficult to define rules. We use CBR as an AI tool to recommend the similar purchase case. A Web-log data gathered in real-world Internet shopping mall was given to illustrate the quality of the proposed mechanism. The results showed that the CBR and web data mining-based hybrid recommendation mechanism could reflect both association knowledge and purchase information about our former customers.

Case-based reasoning is an efficient method to find solutions for new problems by using past cases after appropriate changes. It is widely used in everyday life because it resembles the way human acts. In this paper, we propose a military system that generates the most appropriate tactics for CGF (Computer Generated Forces) by utilizing past practices. It indeed applies case-based reasoning at the process of armed conflict. When the CGF squad on a mission, they will be given an action plan to reach the final goal. In the process of executing, tactics for specific action should be organized such as attacks, ambushes, and tactical moves. By using the proposed method, tactics were generated by case-based reasoning. The proposed system successfully receives input through each command and control agent, measures the degree of similarity with the case in case DB, selects the most similar case, modifies, uses, and then stores it for next time.
