This study focuses on halal certification from the viewpoint of Malaysian restaurant managers. The increasing demand of halal food from the Muslim and non-Muslim consumers has given a good indicator to the hospitality industry to have the eating establishments halal certified. A sample of 643 restaurant managers has been selected throughout Malaysia using systematic sampling. Questionnaires were distributed using mail survey and data was then entered to SPSS version 21 for further analysis. It is gathered from the descriptive statistics that cleanliness during food preparation, meaning of halal and halal certification is important when dealing with food in a Malaysian restaurant setting. The results indicated that restaurant managers have high expectations toward halal certification. Furthermore, halal certification does generate some benefits beyond religion that contribute to Malaysia's positioning as a tourism destination and global halal hub.

The human faces do not have distinct features unlike other general objects. In general the features of eyes, nose and mouth which are first recognized when human being see the face are defined. These features have different characteristics depending on different human face. In this paper, We propose a face recognition algorithm using the hidden Markov model(HMM). In the preprocessing stage, we find edges of a face using the locally adaptive threshold scheme and extract features based on generic knowledge of a face, then construct a database with extracted features. In training stage, we generate HMM parameters for each person by using the forward-backward algorithm. In the recognition stage, we apply probability values calculated by the HMM to input data. Then the input face is recognized by the euclidean distance of face feature vector and the cross-correlation between the input image and the database image. Computer simulation shows that the proposed HMM algorithm gives higher recognition rate compared with conventional face recognition algorithms.

시공간 접근 방법들을 위한 효율적인 성능평가 환경은 최소한 다음과 같은 모듈들을 포함해야 한다. 종합적인 데이터집합의 생성, 데이터집합의 저장, 접근 구조들의 수집과 실행, 실험적인 결과의 시각화 등이다. 데이터집합 저장 모듈에 초점을 맞추어서 다양한 실제 세계 시나리오를 실험하기 위한 종합적인 데이터의 생성이 요구된다. 과거의 여러 알고리즘들은 작업공간에서 미리 분배된 정적인 공간데이터를 생성하기 위하여 구현되어져왔다. 하지만 시간에 따라 변화하는 공간객체인 시공간 데이터를 생성하기에는 어렵다. 이 논문에서 시공간 데이터 타입의 데이터 생성기에서 고려하여야 할 매개변수들에 대하여 논의한다. "Generate_Spatio_Temporal_Data"라는 알고리즘은 움직이는 점 또는 사각형데이터를 생성하고 거래시간과 유효시간을 구별하지 않았으며 시간 점만을 표현하였다. 이 논문에서는 정확한 시간적 개념을 표현하기 위하여 거래시간과 유효시간간격 모두를 지원하는 데이터 생성기에 관하여 논의하기 위한 알고리즘을 제시하고 실제적인 데이터집합 생성을 위한 매개변수들을 나타낸다.

A 5.9kW phosphoric acid fuel cell(PAFC) power generation system that consists of a reformer, a stack, heat exchangers, an automatic data acquisition and control system was designed, fabricated and analyzed. This system which was firstly fabricated in Korea has been operated for 140 hours with an electricity generation of 684kWh. The PAFC generate electricity in the range of 38-52V and 50-160A and has a typical I-V characteristics of a fuel cell. Using the reformed fuel, the system performance is decreased in some degree due to CO content, compared to using the simulated fuel. At steady state operation condition, the total efficency of this system was 45.2%.

A siumlator had been developed and used for reliability verification on medium size steam turbine control programs prior to its actual operation in field. A mathematical model on thermal dynamics pertaining to prime mover steam turbine and electrical generator was realized and included in this simulator. Also, many operating data acquired from fields was utilized in order to decide mechanical and thermal dynamic characteristics such as friction loss, windage loss and inertia. A user can decide closing or opening velocity of steam stop valve and steam regulation valve. This simulator is able to generate steam pressure, turbine speed, electrical power, and power system frequency.

This paper presents the automatic construction of fuzzy rule-based systems for diagnosing the faults of complex systems. Generally, fuzzy systems work well when we can use expert's experience to articulate fuzzy IF-THEN rules and memberships for fuzzy sets. When we cannot do this, we should generate the fuzzy rules and membership functions for fuzzy sets directly from experimental data. In this paper, we propose a new method on how to extract fuzzy sets and fuzzy rules. We also introduce an efficient fine-tunning algorithm of the parameters of membership functions.

The haplotypes of a 200 kb region in the human chromosome X terminal band (q28) were analyzed using the International HapMap Project Phasell data, which had been collected for three analysis panels (YRI, CEU, and CHB＋JPT). When multiple linkage disequilibrium blocks were encountered for a panel, the neighboring haplotypes that had crossover rate of 5% or more in the panel were combined to generate 'haploid' configurations. This resulted in 8, 7, and 5 'haploid' configurations for the panels of YRI, CEU, and CHB＋JPT, respectively. The multiple sequence alignment of these 'haploids' was used for the calculation of allele-sharing distances and the subsequent principal coordinate analysis. Two 'haploids' in CEU and CHB＋JPT were hypothesized as 'parental' in light of the observations that the successive recombinants of these haploids can model two other haploids in CEU and CHB＋JPT, and that their configurations were consistent with those in YRI. This study demonstrates the utility of haplotype phylogeny in understanding population evolution.

Companies need to secure strong methods of new product development in a rapidly changing competitive environment. They overly focusing on the perception of consumers can not lead radical changes. They need to generate sufficient creative ideas in the early stages of new product development to make radical change. The purpose of this study is to examine the effect of a creative method on the generation of creative ideas. An enhanced creativity method was designed considering existing methodology and cognitive elements. This study specifically focused on team rather than individual level creativity. This arrangement reflects the fact that companies in practice rely on team unit in NPD process. The contribution of the study is two fold : enhancing existing methodology, and testing the effect of conceptual distance on making of creative ideas. The experimental results showed that appropriate conceptual distance help to make best creative output and that ABIS attribute is proved to be more effective than traditional association.

We propose a novel multiple-object tracking algorithm for real-time intelligent video surveillance. We adopt particle filtering as our tracking framework. Background modeling and subtraction are used to generate a region of interest. A two-step pedestrian detection is employed to reduce the computation time of the algorithm, and an iterative particle repropagation method is proposed to enhance its tracking accuracy. A matching score for greedy data association is proposed to assign the detection results of the two-step pedestrian detector to trackers. Various experimental results demonstrate that the proposed algorithm tracks multiple objects accurately and precisely in real time.

Luby transform (LT) codes were the first practical rateless erasure codes proposed in the literature. The performances of these codes, which are iteratively decoded using belief propagation algorithms, depend on the degree distribution used to generate the coded symbols. The existence of degree-one coded symbols is essential for the starting and continuation of the decoding process. The absence of a degree-one coded symbol at any instant of an iterative decoding operation results in decoding failure. To alleviate this problem, we proposed a method used in the absence of a degree-one code symbol to overcome a stuck decoding operation and its continuation. The simulation results show that the proposed approach provides a better performance than a conventional LT code and memory-based robust soliton distributed LT code, as well as that of a Gaussian elimination assisted LT code, particularly for short data lengths.
