The inclusion of conductive carbon materials into lithium-ion batteries (LIBs) is essential for constructing an electrical network of electrodes. Considering the demand for cells in electric vehicles (e.g., higher energy density and lower cell cost), the replacement of the currently used carbon black with carbon nanotubes (CNTs) seems inevitable. This review discusses how CNTs can contribute to the development of advanced LIBs for EVs. First, the reason for choosing CNTs as a conducting agent for the cathode is discussed in terms of energy density. Second, the reinforcing effect of CNTs on the anode is described with respect to the choice of silicon as the active material. Third, the development of water-based cathode fabrication as well as dry electrode fabrication with aid of CNTs is discussed. Fourth, three technical hurdles, that is, the price, dispersion issue, and entrapped metal impurities, for widespread use of CNTs in LIBs are discussed.

상주는 귀농 도시이자 농업 중심 도시로써 농업기술원을 유치할 만큼 생태학적 연구가치가 있는 친환경 도시이다. 특히 경천섬은 낙동강 본류에 있는 상주보 인근에 위치하고 있어 낙동강 생태 환경 연구의 중요 지역 중 하나이다. 하지만, 아직 경천섬에 대한 생물다양성 연구가 부족한 상태이다. 섬과 산지의 생태환경이 다르기 때문에 생물의 다양성도 다를 것이라 간주하고, 경천섬 주변의 생태학적 가치를 재조명할 기초자료를 조사하고자 한다. 이에 경천섬과 인근에 위치한 청룡사 길목 산지에 서식하는 곤충 채집을 통해 생물다양성을 조사하여 비교분석하는 것을 목적으로 한다. 채집방법은 직접잡기, 쓸어잡기, 함정트랩, 흡충관을 이용하였으며, 함정트랩에 사용된 유인제는 소주1.8ℓ와 빙초산350㎖를 혼합하여 사용하였다. 2018년 4월~8월 중 3회 채집과정을 수행하여 목표개체수를 확보하였고, 채집된 곤충은 에탄올을 채운 conical tube에 넣어 냉동실에 보관하여 보존성을 높였다. 채집과정에서 잡은 곤충들을 건조시키고 유사종끼리 분류하고 동정하는 과정을 거쳐 다양도지수, 우점도지수, 종풍부도지수, 종균등도지수, 유사도지수를 계산할 것이다. 기존에 알려지지 않았던 경천섬 일대의 생물다양성을 세세하게 분석하는 과정을 통해 경천섬의 생태학적 가치를 드러내고, 경천섬 일대의 자연환경관리와 보존에 필요한 정보나 체계적인 관리체계를 구축할 기초자료를 제공하고자 한다.

The purpose of the present study is to provide exercises, together with music, that are helpful for elderly people’s balancing ability, and to determine their effects in order to provide data for the promotion of elderly persons’health. Thirty elderly persons were randomly assigned to a balance training group(BTG) of 15 subjects, or a music and balance training group (music therapy + balance training [MTBTG]) of 15 subjects; intervention was implemented three times per week for six weeks. To measure the changes in their balancing ability before and after the experiment, the limit of stability, the“Timed Up and Go”(TUG) test, and the Berg Balance Scale (BBS) were measured. Changes in the limit of stability before and after the experiment were shown to be significant in both the BTG and the MTBTG. Changes in the limit of stability of the right side before and after the experiment showed statistically significant differences between the BTG and the MTBTG. Changes in the TUG test and the BBS before and after the experiment were shown to be statistically significant in both the BTG and the MTBTG. The application of music during balance training thus is considered to have a positive effect on elderly persons’balancing ability.

To profile the proteome in porcine plasma, blood samples were collected from adult male barrows and those plasma were retrieved. For the depletion or pre-fractionation of high-abundance proteins, plasma samples were treated with commercial kits. Then, protein profiling was initiated using one and two-dimensional electrophoresis. Proteins were spotted and then identified by MALDI-TOF-TOF and LC-MS-MS. In the results, more than forty six proteins were identified and the reference map was constructed. The pre-treatment for the removal of high-abundance proteins caused the changes in 2-DE images and some of the proteins were newly uncovered after the most of high abundant proteins were removed. However, it is expected for further steps necessary to identify more low-abundance proteins that may contain potential bio-markers.

Polyporus umbellatus (Syn. Grifola umbellata) is a sclerotium forming mushroom belongs to family Poly-poraceae of Polyphorales, Basidiomycota. The sclerotia of P. umbellatus have long been used for traditional medicinesin China, Korea and Japan. This study was initiated to obtain the basic data for artificial sclerotial production of P. umbel-latus. Here, we investigated the favorable conditions for mycelial growth of P. umbellatus and its symbiotic fungus Armill-aria mellea. We also evaluate the favorable carbon and nitrogen sources for sclerotial formation in dual culture betweenP. umbellatus and A. mellea. The favorable conditions for mycelial growth of P. umbellatus were 20°C and pH 4, whileoptimal conditions for mycelial growth of A. mellea were 25°C and pH 6. The carbon sources for optimal mycelial growthof P. umbellatus were fructose and glucose, while carbon sources for favorable mycelial growth of A. mellea were alsofructose and glucose. The nitrogen sources for favorable mycelial growth P. umbellatus were peptone and yeast extract,while optimal mycelial growth of A. mellea were obtained in peptone and yeast extract. When P. umbellatus and A. melleawere dual cultured on carbon sources, sclerotia were induced on basal media supplemented with glucose, fructose andmaltose at pH 4~6, while nitrogen sources inducing sclerotia were basal media supplemented with peptone and yeastextract for 60 days at 20°C under dark condition.

The purpose of this study was to investigate spirometric lung pattern, respiratory function and degree of fatigue by lung function tests and fatigue tests of 39 elderly people in a care facility aged 65 and over. The respiratory function tests were used to the Spirovit SP-1 and fatigue tests were used modified Piper fatigue scale(mPFS). Regarding the respiratory function, the FVC was 1.41±0.36ℓ, the FVC % predicted was 69.10±14.98%, the FEV1 was 1.02±0.31ℓ, the FEV1 % predicted was 63.27±16.05%, the FEV1/FVC was 72.77±13.40%, and the fatigue score was 5.83±1.09. As for the spirometric lung pattern, 19 patients had a restrictive pattern(48.7%), followed by 11 with a mixed pattern(28.2%), 5 with an obstructive pattern( 12.8%), and 4 with a normal pattern(10.3%). Regarding the respiratory function and fatigue by spirometric lung pattern, the FVC and the FVC % predicted of patients with a normal pattern or an obstructive pattern were greater than other groups at a statistically significant level. As for the FEV1, that of patients with a normal pattern was significantly higher than others, and for the FEV1 % predicted, that of patients with a normal pattern or a restrictive pattern was significantly higher(p<.001). Fatigue score by patients with a normal pattern was significantly less than patients of other patterns(p<.001). Therefore, pulmonary physical therapy is considered necessary to improve respiratory function and fatigue degradation of elderly in a facility.

This study was conducted to evaluate the effect of the exercise on elderly balance ability by using hippotherapy and therapeutic ball exercise. 10 patients were assigned to the hippotherapy group and they got with 30 minutes of hippotherapy. Another 10 elderly were assigned to the therapeutic ball group and they got with 30 minutes of therapeutic ball exercise. All procedures were repeated 5 times a week for the total of four weeks. To investigate the participants balancing abilities, the Time“ Up & Go”(TUG) and One Leg Stand Test(OLST) were evaluated. The results of study were significant differences between pre-test and post-test of TUG and OLST(p<.05), and there were no significant differences between hippotherapy and therapeutic ball exercise(p>.05). The conclusion showed that both the hippotherapy and the therapeutic ball exercises were effective on elderly balancing ability. Consequently, it would be better to practice therapeutic ball than hippotherapy for elderly exercise because the more economical and there is less restriction of space than the hippotherapy.

This study aims to reveal how EA affects BAX and NF-kB involved in cell deaths from global ischemia, and to do this, observes the changes of BAX and NF-kB caused by EA application after transient global ischemia. The experimental method is to give rise to global ischemia and apply EA to 27 SD rats with the particulars of being six-week-old, male, around-300 gram-weighing, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 EA group(n=9), L14 EA group(n=9), no-treatment GI group(n=9), and then observe their changes of BAX and NF-kB at the time lapse of 6 hours, 9 hours and 12 hours after ischemia, using western blotting. The numerical decrease of BAX expression at the time lapse of 9 hours after EA application, though not statistically significant, was observed in GV20 EA group and L14 EA group, and the NF-kB expression appeared statistically significant decrease in GV20 EA group and L14 EA group, but the expression was higher in the group with EA application. Therefore, EA application at the early phase of global ischemia is considered to affect BAX and NF-kB and play a positive role in decreasing apoptosis and cell deaths by inflammation.

Since physical therapy was first introduced in Korea, it has been 50 years past and Korean physical therapy has made rapid progress. However, history or educational system of Korean physical therapy is still not known worldwide. Now, for Korean physical therapy to go beyond Asia and leap toward the world, endless studies, efforts and publicity are required. Korean physical therapy first began by missionaries dispatched from other countries like America and Canada with Korean War, which occurred in 1950. After the War, Korean Physical Therapy is devel˗ oped very fast. Korean Physical Therapy Association was founded in October 1, 1965 and many physical therapist were discharged. Korea became a full member of World Confederation of Physical Therapy(WCPT) in 1974, and held the 2nd Asia Pacific Confederation of Physical Therapy assembly in 1984 and WCPT assembly in 2005. Today, in 2010, licensed physical therapists are about 35,000 and there are physical therapy departments in 74 universities, and 17 uni˗ versities have master's or doctor's degree courses. And there are many academic journals(more than 10) related to physical therapy that are published. Many Korean physical therapists are working at various countries like America or Australia, and are acknowledged with excellent treatment technology and academic studies. This thesis aims to shed new light to the history and educational system reorganization of Korean phys˗ ical therapy and introduce it to the world, and establish the historical foundation to develop Korean physical therapy into the international level.

The Ionospheric Anomaly Monitoring by Magnetometer And Plasma-probe (IAMMAP) is one of the scientific instruments for the Compact Advanced Satellite 500-3 (CAS 500-3) which is planned to be launched by Korean Space Launch Vehicle in 2024. The main scientific objective of IAMMAP is to understand the complicated correlation between the equatorial electro-jet (EEJ) and the equatorial ionization anomaly (EIA) which play important roles in the dynamics of the ionospheric plasma in the dayside equator region. IAMMAP consists of an impedance probe (IP) for precise plasma measurement and magnetometers for EEJ current estimation. The designated sun-synchronous orbit along the quasi-meridional plane makes the instrument suitable for studying the EIA and EEJ. The newly-devised IP is expected to obtain the electron density of the ionosphere with unprecedented precision by measuring the upper-hybrid frequency (fUHR) of the ionospheric plasma, which is not affected by the satellite geometry, the spacecraft potential, or contamination unlike conventional Langmuir probes. A set of temperaturetolerant precision fluxgate magnetometers, called Adaptive In-phase MAGnetometer, is employed also for studying the complicated current system in the ionosphere and magnetosphere, which is particularly related with the EEJ caused by the potential difference along the zonal direction.

Effects of substrates, non-aggregated medium and Rootone on the rooting of spearmint (Mentha spicata), peppermint (Mentha x piperit) and catmint (catnip:Nepeta cataria) were investigate and results were as follow. Five types of substrate (saproilite (S), peatmoss (P), S:P 75:25, S:P 50:50, S:P 25:75v/v) were used as rooting media. In the rooting rate and number of roots, peppermint and catmint had higher values in saprolite with significant, but spearmint was shown the better result in S:P 25:75 mixed substrate than saprolite without significances. Root length of spearmint was promoted in mixed substrate of S:P 50:50 and 75;25, and catmint was better in saprolite substrate. Rooting rate and number of roots were shown more decreased in single peatmoss substrate and mixed substrate than saproilte. The effects of aggregated medium (S) and non aggregated medium (tap water) on the rooting of different stem part of mints were tested. Rooting and number of rooting of spearmint and peppermint in water medium were more increased than in saprolite medium. But catmint was not rooted in any medium. Rooting of upper parts with growing points was more increased than under part of stem, which was relative hardy. In Rootone treatments test on rooting of stem cuttings, all treatments very strongly promoted the rooting and number of roots not only in upper stems but also in under part of stem in saprolite and water medium. Rootone treatments (drying 10 minutes after dipping on wetted stem) was very effective in water medium. Especially catmint treated with Rootone promoted a root formation in water medium This research was clarified the possibilities of rooting on spearmint, peppermint, and catmint cuttings in water medium, when especially treated with Rootone.
