Duck-soo Kang.Jee-sun Kim.Jun-hee Hong. 2007. A Study of Obstruents in Yakut through Analysis of Borrowed Words from Russian. Language and Linguistics 39, 1-16. One of the most important constraints in Yakut is connected with syllabic structure. Its syllabic structure is based on CV. So the constraint of "NoGeminates" is strictly applied. And the harmony between features is also considered important. Yakut has the strict constraint on the phonotactical relations. In Yakut a feature [constricted glottis] works more vigorously than [voiced]. This feature is combined with a feature [+back] or [+lab], making new constraints on the initial place: *#[+back, -CG], *# [+lab,+CG]. Finally, consonantal assimilation in obstruents of Yakut is dominated by 2 lows of constraints. VowelHarmony >> Ident-CV[pl] >> NCP >> *[+palatal]# >> Ident-IO; *#[+back, -cont][+back,-high] >> *#[+back,-CG], *# [+lab,+CG] >> [+cont] >> NoGem >> Ident-IO >> *[+voiced]#

In 2007, the Korean Society of Infectious Diseases recommended an immunization schedule for adults residing in Korea. This recommendation includes four categories: standard immunization for healthy persons, supplementary immunization for persons with underlying illnesses, recommendations for health-care personnel and for international travelers. The Standard Immunization Schedule consists of universal vaccination (tetanus-diphtheria/tetanus-diphtheria-pertussis (Td/Tdap); hepatitis A vaccine for persons aged 20s; human papilloma virus vaccine for women under 26 years old; meningococcal vaccine for military recruits and college students in dormitories; influenza vaccination for persons aged 50 years or more and pregnant women; and pneumococcal vaccination for persons aged 65 years or more) and catch-up vaccination (hepatitis A vaccine for persons aged 30s; hepatitis B vaccine, varicella and MMR vaccines for persons who have uncertain specific immunities). The Supplementary Immunization Schedule recommends 4 vaccines, i.e., pneumococcal, influenza, meningococcal, and Haemophilus influenzae type b, appropriate to the underlying illnesses, and confirmation of the presence of antibodies to hepatitis A and hepatitis B. The Recommendation for Health-Care Personnel includes universal vaccination (influenza and pertussis) and catch-up vaccination (hepatitis B, measles-mumps-rubella and varicella for seronegative health-care personnel). The Recommended Immunization for International Travelers focuses reinforcement of vaccinations for healthy persons and includes certain immunizations necessary for international travel (yellow fever, meningococcal, plaque, tick-borne encephalitis, and cholera).

The purpose of this study was to investigate the effect of the MC² learning systems on cognitive ability. Twenty male university students were sellected as subjects and were randomly assigned to both a control (10) and an experimental group (10). Subjects were then pre-tested for simple, and choice reaction time, movement time, short-term memory, probeability and concentration. The practice were for 30 minutes each, 3 days a week for 4 weeks. The finding of this study were as the follows. ① MC² learning system did not increase simple & choice reaction time. ② MC² learning system partly improved of movement time. ③ MC² learning system partly increased short-term memory. ④ MC² learning system did not increased probeability. ⑤ MC² learning system increased the concentration ablility. These test were done with limited subjects over very short experimental period and only a few programs were selected from among the whole MC² learning system. Therefore, more research will be required in well controlled laboratory & field situations to determine the long term effect of MC² learning system.

Five expensive sensors are necessary to control a magnetic bearing system. The sensor price rate of magnetic bearing system is high. So it is necessary that cheap and good sensor is developed. The optical fiber displacement sensor is adaptive to satisfy this condition. We can design magnetically suspended spindle based on static characteristic of optical fiber displacement sensor developed. The controller can be designed by decoupled feedback PD. Therefore, it is simpler than any other controller comparatively.

In this paper, a BPF with a dual mode folded ring resonator is presented. The dual mode ring resonator is also exactly analyzed by using Y-parameter method, in which the difference in admittance of two lines make the ring resonator work as a dual mode resonator. The proposed 'BPF has an advantage of small size compared to conventional one with dual mode ring resonator.

In this paper, we analyzed the dual mode ring resonator of the recently reported Balun-BPF by network Y-parameter analysis. Using the derived Y-parameter and slope parameters, we also verified that the balun conditions of the Balun-BPF at center frequency. This makes it easy to design the Balun-BPF with arbitrary characteristics.

Due to the lack of stiffness and difficulties of control, it is hard to achieve well balanced magnetic levitation. In this paper, we analysis the current and position stiffness change according to bias current through experiment. Then, compensation equations were presented. After obtaining PD gain for each bias current and PD gain region through levitation experiment, we consider the characteristics.

The studies on physico-chemical factors and phytoplankton at the 3 rivers in the Taejon city were conducted from November 1997 to May 1998. The Results were as follows; In the water quality, the down streams were generally worse than the upper streams. Water temperature was varied from 2.4℃ to 23.0℃; DO from 1.80㎎/ℓ to 17.6㎎/ℓ ; pH from 4.7 to 10.4 ; BOD from 0.78㎎/ℓ to 8.80㎎/ℓ; COD from 0.32㎎/ℓ to 8.26㎎/ℓ ; SS from 2.0㎎/ℓ to 43.0㎎/ℓ ; total phosphate was from 0.001㎎/ℓ to 0.709㎎/ℓ ; total nitrogen 0.01㎎/ℓto 11.69㎎/ℓ . In phytoplankton species, they were identified as total 191 taxa composed of 8 classes, 18 orders, 35 families, 74 genera, 152 species, 35 varieties and 4 forms. The dominant species were Synedra ulna in Taejon-chon, Diatoma vulgare in Yudong-chon, Oscillatoria princeps, Scenedesmus gadricauda, Synedra ulna, and Diatom vulgare in Gap-chon. Standing crops of phytoplankton were from 2,076 cells/㎖ to 97,356 cells/㎖.
