Indigenons malaria which was recognized as one of the unavoidable disease has almost eliminated from this country. Recently, we must attend to imported malaria cases because of an increase in overseas travelers and workers to tropical countries where malaria is endemic. Sometimes resistant to conventional drug therapy. So, imported malaria become a new health problem. We experienced a case of imported falciparum malaria. which is resistant to CHLOROQUINE and cured by QUINIE SULFATE and FANSIDAR.

The 'Science and Technology Mania' award program is an annual nationwide award activity organized to provide teenagers with opportunities for engaging in a high-technology-based long-term project work. The task involves designing a model ship propelled by the Lorentz force (a Lorentz ship) that allows diverse approaches irreducible to one right answer, and thus adopts features of science and technology in-the-making, In this study, we attend to opportunities for learning science that the uncertain aspects of artifact-designing project provide with participants, particularly when students communicate with scientists about their design practices. We analyze oral presentation sessions of the program and articulate two findings. First, students articulate embodied knowing in the presence of scientists. Second, students enact discursive resources deployed in concrete action. We conclude that students' design practices constitute referent that communication is directed toward and therefore become resources for developing scientific discourse.

Consider a multi-floor facility with multiple rooms of unequal size on each floor. Students come from many organizations to attend the conference to be held at this facility. In assigning the rooms to the students, several constraints must be met; such as boys and girls must not be assigned to the rooms on the same floor. Given the capacity of each room and the number of students from each organization, the problem is assigning students to rooms under a set of constraints and various objectives. We present six models with different objective functions; and formulate them as binary integer programming problems. A numerical example and a case study follow to illustrate the proposed models.

As the workers are getting old, they need to be expert in their fields. Expertise is an invaluable means of shipbuilding industries because of the technological advancements. Therefore, the workers have to attend training seminars and upgrade their technical knowledge. In shipbuilding industries, most workers operate transporters based on experience not on learning from specialization in the shipyard. It is needed for the workers of transporters to be educated technical manual and system. Thus, this research shows that educational system which is interactive and very effective with Augmented Reality(AR) for the non-specialist workers. The educational interactive system based on AR is very supportive and worth for the workers. This study considers the system which makes the workers reduce malfunction of the products and mistakes.

Background: This study was conducted to prove the effects of the Schroth exercise on sagittal postural alignment to the visually impaired students. Methods: The subjects were 8 students who attend the special school in Daegu and performed the Schroth exercise 3 times per week for 3 weeks. Craniovertebral angle and pelvic alignment were measured to compare the effects of the exercise. Results: Craniovertebral angle and pelvic alignment on sagittal plane showed significant differences (p<.05). Conclusions: Schroth exercise was effective to improve postural alignment of sagittal plane to the visually impaired students and these results will have a positive impact on future study of improvement of postural alignment on sagittal plane to the visually impaired students.

The Korean high back vowels /o/ and /u/ have been reported to be in a state of near-merger especially among young female speakers. Along with cross-generational changes, the vowel position within a word has been reported to render different phonetic realization. The current study examines native English speakers' ability to attend to the phonetic cues that distinguish the two merging vowels and the positional effects (word-initial vs. word-final) on the identification accuracy. 28 two-syllable words containing /o/ or /u/ in either initial or final position were produced by native female Korean speakers. The CV part of each target word were excised and presented to six native English speakers. The results showed that although the identification accuracy was the lowest for /o/ in word- final position (41%), it increased up to 80% in word-initial position. The acoustic analyses of the target vowels showed that /o/ and /u/ were differentiated on the height dimension only in word-initial position, suggesting that English speakers may have perceived the distinctive F1 difference retained in the prominent position.

This study investigated the factorization concept development level of 3rd grades in middle school, the success of factorization problem solving, and the completion of factorization analogy tasks and science concepts analogy tasks. This study's results are followings. 1. Based on Sfard' reification levels, we classified students' factorization concept development levels from level 0 to level 3. As the students' development level was high, they tended to succeed the factorization problems gradually. 2. Experiencing factorization tasks which made students arrange factorization expressions hating same characterization, students ' factorization problem solving was improved. And, as the students' development level was high, they tended to attend to internal structural relations in factorization analogy tasks. 3. Analogy in factorization wasn't interrelated with analogy in science concepts. It said that analogy depended on the knowledges with it.

The JXTA was made in order to solve the problem of being generated with the computer platform suggested with the P2P(Peer-to-peer) method in the distributed computing. JXTA makes a communication between the various network and the devices is connected to a network which possible. It was designed to the client having the minimum computing ability could attend in the peer-to-peer network. However, for smoothly applying JXTA in the wireless environment, there is a limit with the limited resource of the Mobile Device. By using the Relay of the JXTA based for the Mobile Device, this paper implemented the P2P service which is flexibly effective in the wireless network environment.

The new paradigm of education in the cyber space is not limited by time or locations. The students do not need to attend classroom physically and simultaneously. This study tries to probe the relationships among demographic variables and instructional variables with students' satisfaction with the management class in a cyber university. The results demonstrate that demographic variables are not significantly related with students' satisfaction. Rather instructional variables such as personal interactions with professors, job related contents and careful reduction of difficulties countered during the class proceeding are more significantly related with learning satisfaction. The result shows the newly emerged internet based education system requires in-depth cooperation among professors, system engineers, education instrument designers, and students.

The new way of doing education in the cyber space is not limited by time or locations. The students do not need to attend classroom physically and simultaneously. This study tries to probe the relationships among demographic variables and instructional variables with students' satisfaction with the management class in a cyber university.
