The purpose of this study was to determine a more effective method for shoulder pain reduction. Forty-five normal subjects were randomly assigned to one of 3 groups a control group, an acupuncture-like transcutaneous electrical nerve stimulation(ALTENS) group, and a silver spike point(SSP) group. Each person in the ALTENS and SSP groups was measured for pressure pain threshold before and after a 20 minute treatment. The control group was also checked for pressure pain threshold before and after a 20 minute period but no "treatment" was given. The major findings were as follows ; 1)The ALTENS and SSP groups showed significant differences before and after treatment but the control group showed no significant difference. 2)When the three groups were compared, the only significant difference was between the SSP group and the control group. As mentioned above, it may be concluded that both ALTENS and SSP therapy were effective in reducing shoulder pain when measured directly after treatment. However, SSP did not show any superior effect. Further study should be done to determine the effective the maintained pain reduction with post-treatment time lapse.

In this study, solid-liquid separation conditions for coagulation and sedimentation experiments using inorganic coagulant (aluminum sulfate and Poly-Aluminum Chloride (PAC)) were optimized with brine wastewater discharged by the epoxy-resin process. When the turbidity and suspended solid (SS) concentration in raw wastewater were 74 NTU and 4.1 mg/L, respectively, their values decreased the lowest in a coagulant dosage of 135.0 - 270.0 mg Al3+/L. The epoxy resin was re-dispersed in the upper part of wastewater treated above 405.0 mg Al3+/L. The removal efficiencies of turbidity and SS via dosing with aluminum sulfate and PAC were evaluated at initial turbidity and SS of 74 - 630 NTU and 4.1 - 38.5 mg/L, respectively. They increased most in the range from 135.0 - 270.0 mg Al3+/L. The solid-liquid separation condition was quantitatively compared to the correlation of SS removal efficiency between the coagulant dosage and SS concentration based on the concentration of aluminum ions. The empirical formula,   , shows the relationship between SS removal efficiency (R) and coagulant dosage (D) at 38.5 mg/L; it produced high correlation coefficients (r2) of 0.9871 for aluminum sulfate and 0.9751 for PAC.

The purposes of this study were to classify detailed climate types over the Republic of Korea (ROK) and to delineate their climate characteristics using the new normals of 1991-2020 for 219 weather stations. Total five climate types, Cfa, Cfb, Cwa, Dwa, and Dwb were identified in ROK based on the Köppen’s climate classification criteria. Subtropical climate types, Cfa or Cwa types were broadly covered with 79.9% of 219 stations and the most of remaining stations were included in Dwa types which had a very cold winter and hot summer with wet conditions. In the Trewartha classification, four climate types were identified, one subtropical Cfa, and three temperate Doa, Dca, and Dcb types. Dcb types were found at four stations (Daegwallyeong, Taebaek, Jinburyeong, and Sabuk) in Taebak mountains indicating the extent of cool summer climate types with more stations in mountain areas. The climate characteristics by climate types only were presented the results from the Trewartha classification with the new normals and 66 ASOS stations because Köppen’s climate classification was not appropriate for ROK. The annual mean precipitation of Cfa was the greatest while Dcb the lowest among four types. The annual range was the greatest at Dca types while the smallest at Cfa due to the geographical varieties. More detailed climate types were located in ROK with 219 weather stations and the new normals (1991-2020). However, there were some limitation applying the criteria of Köppen’s and Trewartha’s climate classification to a very complex topographical region.

This paper has presented not only the spatial coverage change of climate extreme events in summer and winter seasons during the period of 2000-2017, but also their future projections in 2021-2100, South Korea through analysis of a Combined Climate Extreme Index (CCEI). The CCEI quantifies the spatial coverage of climate extreme events based on a set of five indicators. MK (Modified Korean)-PRISM (Parameter-elevation Regression on Independent Slopes Model)v1.2 (1×1km) and RCP scenario data (1×1km) were applied to CCEI. Results indicated that in average, 21.7% of the areas in the summer and 23.6% in the winter experienced climate extremes from 2000 to 2017 regardless of types of climate extreme events in South Korea. The summer of 2003 and 2009 was relatively cool and humid, while the summer of 2014 and 2015 was cool and dry and the summer of 2016 was warm and dry. The extreme events with much above normal maximum and minimum temperature during the study period were detected but not much below normal maximum and minimum temperature after 2015. For RCP2.6 and RCP8.5 scenarios, there were statistically significant trends with spatial coverage expansion of climate extreme events in the future. It might be concluded that climate extreme events in the summer and winter seasons were affected simultaneously by two or more indicators than a single indicator in South Korea.

목적: 본 연구의 목적은 생리조절과 인지조절 심리기술훈련이 시합 스트레스 상황에서 선수들의 심리 및 동기체 계에 영향을 미치는 방식을 전두엽 좌우뇌 비대칭을 통해 조사하는 것이다. 방법: 연구대상자는 대학 남자 축구 선수 30명으로, 생리조절군 8명, 인지조절군 8명, 통제군에 14명씩 무작위 할당되었다. 심리기술훈련은 3주간 단 체훈련 3회기, 개인상담 3회기로 총 6회기가 진행되었다. 심리기술훈련 전과 후 휴식과 스트레스 회상 조건에서 심리상태와 전두엽 좌우뇌 비대칭값(Frontal EEG Asymmetry Score: FAS)이 측정되었다. 결과: 스트레스 조건에서 측정된 불안, 스트레스는 생리조절, 인지조절 집단 모두 훈련 전보다 후에 감소하였으나, 통제집단에서는 차이가 없었다. FAS 분석결과, 생리조절군의 FAS는 훈련 후 Fp2의 활성화 감소에 의해 음(-)의 방향으로 하락한 반면, 인지조절군의 FAS는 훈련 후 Fp2의 활성화 증가에 의해 양(+)의 방향으로 상승하였다. 이상적인 심리상태 유도를 위해, 생리조절훈련은 철회동기체계를 작동시켜 스트레스 상황을 회피하는 방식을, 인지조절 훈련은 철회 동기를 감소시켜 상황에 대한 적극대처 방식으로의 전환을 보였다. 결론: 본 연구는 심리기술훈련의 유형과 방식에 따라 심리변화를 유도하는 과정과 동기체계에 차이가 있을 수 있음을 확인하였다.

An application of an integrated climate extreme index (CEI) is presented, that quantifies observed climate change of South Korea by various five indicators. Based on an annual basis surface observation station data, climate extreme indicators that measure the fraction of the stations in South Korea are analyzed. Results for the annual CEI indicate that the area experiencing much above-normal maximum and minimum temperatures in recent years has been increased. The extremes in much greater-than-normal number of days with or without precipitation has a large interannual variability similar with much above and below normal standardized precipitation index. Results from above-normal proportion of heavy daily precipitation show a more pronounced increasing feature from 1990’s to the early 2010’s. Five indicators in CEI had distinct contrasting features which indicates that CEI can be a useful tool in providing the information on the percentage of the climate in South Korea that experienced various kinds of extreme conditions during any given year or period.

Cell based grid data of future temperature and precipitation produced with four RCP scenarios were converted into polygon based data for administrative districts using three simple vectorizing methods; (1) KMA Dong-Nae forecast point based, (2) areal ratio based and (3) central point based methods. The results were compared the existed KMA areal weight based methods to identify which methods were more efficient than others. Simple statistical methods such descriptive statistics, correlation coefficient, and Bland & Altman plots (B&A) were used to compare agreements between them. When central point and areal ratio based methods were applied to administrative districts of Eup-Myeon-Dong or some Gus, NULLs were found because their sizes are smaller than the cell of 1x1 km. Therefore, KMA Dong-Nae forecast point based methods were better when sizes of administrative districts are smaller than the cell size. For Do and Metropolitan cities, there were no greater differences among methods except for the KMA Dong- Nae forecast points. The greater the areas of administrative districts the more distortions from the KMA Dong-Nae forecast points because only KMA Dong-Nae forecast one point were used for the calculation. In conclusion, the KMA Dong-Nae forecast point based method was appropriate when sizes of administrative districts are smaller than the grid cell. For the greater areal sizes such as Do and Metropolitan cities, areal ratio and central point based methods were better.

한때 K 뷰티 열풍과 함께 호황을 이루던 로드숍이 위기를 맞게 되었다. 로드숍 경영 악화의 여러 이유 중 드러그 스토어의 성장과 함께 변해가는 소비자의 성향과 트렌드를 이해하지 못하는 것이 가장 큰 원인으로 보고 있다. 현재 소비시장의 핵심 고객 세대는 베이비붐세대에서 밀레니얼 세대로 변하였고 핵심 고객의 특성을 조사하는 과정에서 밀레니얼 세대는 경험을 중요시한다는 것을 알 수 있었다. 본 연구는 뷰티숍 경험을 바탕으로 서비스 디자인을 제안하였다. 먼저 현 뷰티 시장에서 세 가지 브랜드로 좁혀 사례마다 데스크 리서치 하였다. 각각의 브랜드는 체험적 요소를 다양하게 적용하고 제품과 함께 다양한 이벤트를 제공함으로써 경험적 서비스 제공하고 있었다. 이후 미스터리쇼핑을 통해 각 매장의 체험 요소와 뷰티 브랜드 서비스를 경험하여 여정 맵을 그리고 소비자의 고객 경험 포인트가 매장, 제품, 서비스로 범위가 나뉘면서 경험 포인트별로 로드숍의 이용자를 대상으로 인터뷰 내용을 작성하였다. 인터뷰의 답변을 모아 두 명의 퍼소나를 설정하였고 제품 구매를 목적으로 하는 상황과 일상에서 코스메틱 제품이 필요한 상황으로 나누어 고객 여정 맵을 그렸다. 그 결과 매장 안의 제품에 대해서 5가지, 매장 환경에 대해서 3가지, 매장에서 경험하는 서비스에 대해서 5가지의 페인 포인트(Pain point)를 발견하였다. 발견한 페인 포인트(Pain point) 중 제품 정보 습득에 대한 불편함, 포인트에 대한 적은 기대치, 브랜드 서비스의 해결방안에 중점을 두어 애플리케이션을 활용한 서비스 디자인을 제안하였다. 본 연구에서 제안된 코스메틱을 위한 애플리케이션 서비스는 고객뿐만 아니라 뷰티 전문가, 코스메틱 업체 모두 만족할 수 있는 서비스 디자인으로 소비자와 소통하고 경험 디자인을 통하여 브랜드 가치 상승과 충성고객을 이끌어 가는 매개체가 되길 희망한다.

This paper has identified detailed climate types and their geographical extents in the Republic of Korea using MK (Modified Korean)-PRISM (Parameter-elevation Regression on Independent Slopes Model) 1×1km high-resolution grid climate data and Trewartha climate classification. When considering 60 ASOS (The Automated Synoptic Observing Systems) stations, only four climate types were identified over South Korea. Three climate types, Dca (52%), Doa (28%) and Cfa (18%), were prevalent while Dcb type was only located at Daegwallyeong. When based on a high-resolution grid climate data, six climate types were identified including Dob and E types which were not detected with ASOS stations. High-resolution grid climate data reflected better and detailed geographical characteristics. Areas occupied by Cfa climate types were located along the narrow southern and Jeju coastal areas, dedicating only 6.9% of South Korea. Trewartha climate classification was also applied to 1km×1km RCP scenarios. The most distinct feature of future climate changes based on RCPs was a larger expansion of Cfa and Doa types with a drastic reduction of Dca and Dcb, indicating that a warmer and wetter climate would be prevalent over South Korea in the latter period of this century. Even for RCP2.6, all the coastal areas, some of Seoul metropolitan area, a large part of Daegu and Gwangju metropolitan areas would be classified as Cfa. For RCP8.5, 51.5% of South Korea would be occupied by the Cfas and 25.1% by the Doas, leaving only 23.2% of Dcas.

Background : Panax ginseng the king of Oriental medicines, has enormous potential against many of the disease symptoms and ailments. Panax quinquefolius is an another important member of Panax family which has similar benefits and medicinal properties. Both the species contains ginsenosides a pharmacologically active component abundant in their roots. In an effort to establish the new ginseng cultivars with improved agronomical characters such as root shape, stress tolerant and higher ginsenoside contents, the reciprocal interspecific hybrids were generated Methods and Results : Four elite cultivars and two new lines of ginseng were chosen to produce interspecies reciprocal hybrids with P. quinquefolius, by pollen dusting on the emasculated flowers. Among the F1 populations, the reciprocal hybrids generated by using new line 0837 both as maternal and paternal parent showed better properties and hybrid vigor. They showed strong root phenotypes with many lateral and fine roots thus having 10% to 20% higher ginsenoside contents compared to the parental populations. Among the major ginsenosides, the pharmacologically active ginsenosides such as Re, Rb1, Rb2 and F1 were enriched and accounted for the 70% of the PPD ginsenosides in 0837/Pq and Pq/0837 crosses, displaying strong dominance. Conclusion : Thus, based on our result we could conclude that P. ginseng line 0837 is the superior variety compared to the already existing lines for performing the interspecific hybrids with promising outcome in their root quality and ginsenoside content.

Background : Panax ginseng Meyer, the king of Oriental medicine is a geophytic perennial shrub. P. ginseng possess long juvenile period which spans for at least 3-years before it could attain reproductive competence. To explore the significance of flowering time genes we isolated, characterized the Flowering Locus T (FT) gene and named as PgFT1 and PgFT2 to understand their role in ginseng floral transition. Methods and Results : By using extensive cloning and bioinformatics analysis we identified two FT homologs from ginseng a. The deduced PgFT sequences has a considerable homology to established FT homologs with the essential amino acids of a florigen function conserved. The tissue specific expression profiling by Real-time qPCR from the juvenile (2-years-old) and adult (4-year-old) ginseng plants have shown a spatial and temporal expression pattern, furthermore PgFT transcripts exhibited photoperiod dependent oscillation as well. Besides, PgFT1 and PgFT2 have shown an age specific expression pattern, in particular the transcripts were concentrated to the roots of P. ginseng. The ectopic expression of PgFT homologs in Arabidopsis thaliana induce precocious flowering by altering several floral pathway integrators, in addition PgFT1 transgenic Arabidopsis seedlings had an increased root length while, the influence of PgFT2 in transgenic seedlings apart from flowering is as yet to be revealed. Conclusion : Based on our results, we alleged the spatial and temporal expression of PgFT homologs could be significant in the flowering time transition of ginseng and their age specific expression pattern suggests the roots of ginseng are influential in determining the reproductive competency. On top of it, results from transgenic studies in Arabidopsis claimed that PgFT1 might involve in the underground organ development. Albeit, their molecular regulation, developmental role and the manipulation of PgFTs in ginseng flowering warranties further investigation.

Background : Bokbonja the Korean black raspberry (Rubus coreanus Miquel) fruit derived product, which is native to Korea. They contain potential anti-aging, anti-oxidants, depurative activities. Bokbonja refers to an immature berry of Rubus coreanus in the Korean pharmacopeia, Rubus chingii in Chinese pharmacopeia. Recently several Rubus species are available in the Korean drug markets which could easily find their way into drug prescriptions. Methods and Results : Hence we tried to detect the presence of these contaminating species in bokbonja products using SNP marker assisted by multi-plex PCR. We found a SNP region in the 26S region of these species and evaluated their potential to discriminate Rubus species. We designed a set of primer pairs such as, BokR primer has distinguished R.coreanus by producing a band at 852 bp and the primer sanF has differentiated R. crataegifolius by amplifying a band at 129 bp, while chiF has produced a band at 83 bp to distinguish R.chingii. These primer pairs effectively distinguished the bokbonja samples collected from various local markets as well as form drug store in Korea as well. The results were shocking as the bokbonja (R.coreanus) has a limited usage in Korea and either R. crataegifolius or R.chingii has been found in these samples. Taken together the primer pairs bokR, sanF, chiF along with 26S universal primers could effectively distinguish Rubus species in a single multiplex PCR reaction. Conclusion : Our results based on the 26S rDNA derived SNP region have shown that, the usage of R. coreanus is extremely limited and its often mistaken or adulterated with R. crataegifolius and R. chingii. It presses a panic situation in Korean peninsula to preserve bokbonja and the species R.coreanus which is endemic and superior in efficacy.

Background : Ginseng root rot is a devastating disease caused by the fungus, Ilyonectria mors-panacis that generally attacks younger roots (-2 years), leading to defects in root quality, ginsenoside accumulation and also life cycle of the plant. Hence, there is an indispensable need to develop strategies resulting in tolerance against ginseng root rot. The protective role of silicon during pathogen infestation is well documented in other plant systems and a previous study demonstrated that silica nanoparticles are absorbed and accumulated more than the bulk silica in maize. However, the role of silica in ginseng-root rot pathosystem is unknown. Methods and Results : In the present study, we evaluated the effect of silica nanoparticles (N-SiO2) in Panax ginseng during I. mors-panacis infection. Long term analysis (30 dpi) revealed a striking 50% reduction in disease severity index upon 1 mM and 2 mM treatment of N-SiO2. However, N-SiO2 did not have any direct antifungal activity against I. mors-panacis. Candidate genes and metabolites based approach revealed jasmonic acid (JA) mediated sterol accumulation and incresed ginsenside biosyntesis as the key transcriptional reprogramming events orchestrated by N-SiO2 during the fungal infection. Conclusion : In a nut shell, N-SiO2 administration induces transcriptional reprogramming in ginseng roots, leading to increased phytosterol and ginsenosides synthesis resulting in enhanced tolerance against I. mors-panacis.

This study was carried out to investigate the physicochemical and antioxidant properties of fermented milk with addition of hot water extract of Cordyceps militaris grown upon Tenebrio molitor. The general components of Cordyceps militaris grown upon Tenebrio molitor are moisture 10.85%, crude protein 18.44%, crude fat 2.07%, crude ash 5.46%. The DPPH radical scavenging activities of different solvents were the highest (74.81 EDA%) with hot water extract sample. The acidity of fermented milk was high with increasing amount of extracts. The pH of fermented milk reached 4.60-4.66 after 4 h of fermentation, and the number of lactic acid bacteria was highest (11.70 log CFU/mL) with 1% fermented milk. The moisture content of fermented milk showed no significant difference. In addition, contents of crude protein were not significantly different according to addition amount. Regarding Hunter’s color values, L value decreased as the amount of extract increased, whereas a value and b value increased. The content of free amino acid increased with increasing amount of extract. The DPPH free radical scavenging ability and ABTS free radical scavenging ability of fermented milk were significantly different as the addition amount of extract increased. In the sensory evaluation, fermented milk containing 1% of extract showed the highest preference.

환경부에서 발간한 2016 환경백서에 따르면 2016년도 말 현재 주요축종(한육우, 젖소, 돼지, 닭･오리)의 경우 10만 5천여 축산농가에서 19,190만 두의 소, 돼지 등을 사육하고 있는데, 가축사육 두수가 증가됨에 반해 축산농가는 감소하고 있어 전업화, 기업화 추세가 지속되고 있는 중이다. 주요 축종의 가축분뇨 연간 발생량은 46,988천 톤이며, 가축 분뇨의 처리는 발생량 중 약 90.6%는 자원화시설에서 퇴비･액비화 하고 있으며, 8.2%는 개별시설이나 공공처리시설을 통해 정화처리하고 있다. 그러나, 가축사육두수의 증가에 따라 일부 지역에서의 지역 내 수용할 수 있는 환경용량을 넘어서는 양의 가축분뇨가 발생되면 일부 불량한 품질의 가축분뇨가 유통되어 악취 등 생활환경 문제를 야기함과 함께 살포지를 확보하지 못하고 생산된 퇴비･액비가 수요가 없어 지속적으로 쌓이게 되고 저장할 공간 및 시설부족에 따라 퇴비·액비가 강우 등에 노출되어 인근 유역에 유입됨에 따라 수질에 중대한 영향을 미치는 상태가 발생한다. 따라서, 본 연구에서는 가축분뇨를 고압착 필터프레스를 이용하여 고 함수율(80%내외)의 1차 탈수슬러지를 60% 내외의 저 함수율 탈수케이크로 전환하는 고효율 재탈수공정 후 진공감압 가열건조 함으로써 에너지 소비를 절감하고 Dies 형태의 성형장치를 이용한 펠렛 형태의 고체연료를 생산하는 기술을 개발하고 실증화 실험을 수행(고체연료 10ton/일 생산)하였다. 고압착 필터프레스를 이용하여 고액분리 시 가축 분뇨는 유기물 함량이 높아 난탈수성이므로 탈수율을 증가 시킬수 있는 효과적인 탈수 보조제의 종류 및 함량의 변화에 따라 나타나는 차이를 분석 해석을 실시하였다. 또한 건조 시 저온에서도 물의 증발이 원활히 이루어질 수 있도록 진공상태를 부여하고, 고압착 필터프레스로 건조 시작 지점을 점착성 단계를 지나 입자화 단계에서 진행함에 따라 건조 속도 및 건조열효율의 효과를 알아보고자 하였다. 건조 후 Dies 형태의 성형장치를 이용하여 펠렛 형태로 성형된 가축분뇨 고체연료가 가축분뇨 고체연료시설의 설치 등에 관한 고시의 가축분뇨 고체연료 기준에 만족하는지에 대하여 알아보고자 하였다.
