Eco T-shirts have become a part of environmental campaigns following social trends toward eco-friendly designs. With the demand for such designs expected to grow, there has arisen a need for higher product variety. In the past, eco T-shirts were designed to convey messages about the protection of nature through the use of environmentally friendly text or images. However, in order to respond to the preferences and emotional needs of Koreans, designs should cater to their characteristics and tastes. To this end, this study used a Whan-ki Kim-inspired motif to develop an eco-friendly design tailored to Korean perspectives. It is believed that this process can not only result in a distinctive eco T-shirt design, but also make it globally competitive. With regard to research methodology, a total of 41 paintings of Whan-ki Kim were analyzed and classified into four major themes or key values expressed in modern eco-friendly fashion designs: naturalness, indigenousness, harmony between nature and man, and harmony between natural and artificial beauty. Employing a wide range of CAD techniques and varying forms, the themes were developed into 28 T-shirt designs after their forms, tones, and textures were fully explored. This study demonstrates the possibility of designing creative, aesthetic, and high value-added eco T-shirts through motif development. In addition, it successfully integrates Korean paintings in the development of T-shirt designs aimed at communicating environmentally friendly messages.

Seasonal and vertical distributions of dissolved and particulate organic carbon were investigated from May 1995 to March 1997 in n deep mesotrophic reservoir, Lake Soyang, POC contentrations at the dam site ranged from 0.1 to 1.8 mgC/L and DOC concentrations ranged from 1.4 to 4.9 mgC/L. POC concentrations in the surface layer were higher in the season of cyanobacterial bloom, July to September. High POC was observed at the depth of 30 to 60m after storm runoff in summer monsoon season. Turbid storm runoff formed intermediate current laden with much particulate materials from terrestrial sources. The vertical and seasonal variation of DOC was smaller than POC. Higher DOC was observed near the lake bottom which implies sedimentation and degradation of much organic detritus at the bottom. The ratio of DOC : POC varied from 2 to 60, and the ratio was lowest in September 1995 when algal density was highest. DOC : POC ratio of the main inflowing river, the Soyang River, varied from 1 to 10, and the ratio was low in storm runoff when the POC concentration was high.

The trend of trophic status change in Lake Soyang from 1981 to 1989 was studied by the measurement of chlorophyll a concentration, transparaency, total phosphorus concentration, and the rate of hypolimnetic oxygen deficit rate. And the phosphorus loading from the watershed was measured monthly at the main inflowing river, Soyan River. The increasing trend of chlorophyll was clear at the rate of 0.4 /￡㎍/l/yr. The advent and expansion of Anabaena bloom was the major cause of chlorophyll, increase and transparency reduction. The rate of hypolimnetic oxygen deficit also increased from 0.032 mg Ο_(2)/cm^(2)/day in 1986 to 0066 in 1988. The trophic state of Lake Soyang can be assessed as oligotrophy before 1983, mesotrophy from 1984 to 1988, and eutrophy since 1989. Phosphorus loading from floating net fishfarms was estimated to be larger than 45% of total. The phosphorus loading from only watershed is smaller than the dangerous critical loading, but, if the fishfarms loading added, it exceeds the critical loading.

Trophic states were surveyed in reservoirs of the Han River. Trophic states were assessed from chlorophyll a concentration, Secchi sisc transparency, total phosphorus andprimary productivity in recent several years. Trophic state indices(TSI)sere calculated from the summer-time average of water quality data. TSIs were in the rage of mesotrophy to eutrophy, from 40 to 55. The highest TSI of all the frservoirs of the Han River was observed at the inlet of the south Han River in Lake Paldang. TSI varied with year because of such event as turbid flood inflow, water bloom, and descending water level. The correlation ceofficients between the six TSIs were high, but the probabilities of paired T-test were very low, which means significant differences in the absolute dimensions of the TSIs. The correlation between TSI (SD) and TSI (TP) was highest and TSI(Chl) showed lower correlation with TSI(SD) and TSI(TP)

소양호에서 인의 존개 형태별 분포에 관하여 : The Distribution of Phosphorus Fractions in Lake Soyang

김범철,허우명,황길순,김동섭,최광순 江原大學校 附設 環境硏究所 1996 環境硏究 Vol.13 No.-

The distribution of phosphorus in Lake Soyang from January 1985 to August 1992 was surveyed by the measurement of soluble reactive phosphorus(SRP), total dissolved phosphorus(DTP), and total phosphorus(TP) concentration. SRP concentration was in the range of 2~7㎎/㎥ in epilimnion, and 4~200㎎P/㎥ in hypolimnion. The vertical distribution pattern of SRP showed a large difference with the season. SRP concentration decereased during the growing season of phytoplankton in the epilimnion of Lake Soyang and increased in hypolimnion during the oxygen depletion. Higher concentration near the bottom implies they are diffused from the bottom sediment where organic particles are settled and degraded. SRP, DOP, POP and TP concentration was higher in the meralimnion of Lake Soyang in rainy season It might be related with storm runoff. General trend of TP variation is that the TP concentration of water column is increasing substantially from yeat to year. TP concentration in the surface water increased from 5㎎P/㎥ at 1985 to 20㎎P/㎥ at 1992.

본 실험에서는 Fe합금으로 소결된 기어부품을 특성향상을 위해 여러 조건에서 플라즈마 질화 처리를 실시하여 특성을 평가하였다. 특성평가는 광학현미경, XRD, 비커스경도계, 표면조도계를 이용하여 실시하였다. 특성평가 결과 질소의 분율이 높아질수록 화합물층의 두께는 증가하였고 질화처리 온도가 증가할수록 표면의 경도도 약 Hv150에서 Hv300, Hv400 으로 증가하였고 표면의 조도(Ra)값도 0.33㎛에서 0.57㎛로 증가하였다. XRD 측정결과 모든 조건에서 Fe4N상이 나타나는 것을 볼 수 있었고 처리온도가 올라갈수록 Fe4N상이 성장하는 것을 볼 수 있었다. Sintered Fe-alloy gear parts were plasma nitrided, and the influence of nitriding treatment condition(temperature, gas mixture, duty ratio)on the surface layer microstructure, compound layers properties of the gear part has been studied. Properties of the nitrided layer were analysed by using optical microscope, X-ray diffractometer(XRD), micro-vickers hardness tester, roughness tester. It was found that compound layer thickness increased with increasing ratio of N2 gas mixture and surface hardness, roughness increased with increasing nitriding temperature.

Trophic states were surveyed in a reservoir on the Han River, Lake Paldang, receiving waters from two rivers, the North Han River and South Han River. Chlorophyll a concentration, secchi disc transparency, BOD, soluble reactive phosphorus (SRP) concentration and total phosphorus (TP) concentration were investigated at three sta-tions (dam site and the inlet region of the North Han River and the inlet region of the South Han River) and the phosphorus loading into Lake Paldang was measured. Chlorophylla, BOD, SRP and TP were highest at the inlet region of the South Han River and lowest at the inlet region of the North Han River and eutrophic level at the inlet region of the South Han River. The phosphorus loading into Lake Paldang was between the dangerous critical loading and the permissible critical loading of Vollenweider-OECD critical loading model. The phosphorus loading of the South Han River was about 2 times larger than of the North Han River.

In recent years, the study on the porous concrete which has excellent permeability is actively advanced in the field of architectural and civil engineering. But porous concrete has a reciprocal concept in the aspect of comparative large and continuos void structure and reduction of void for insurance of the necessary strength on the mixing proportion, must have satisfied of the properties of these. Therefore this study is series of experiment for the strength elevation and evaluated the effect according to adding ratio fly-ash, fine replacement ratio, cement content and coarse aggregate max size. As a result, the strength of porous concrete was elevated by an increase of adding ratio fly-ash, fine replacement cement content and a decrease coarse aggregate max size.

소양호의 용존산소 수직분포를 1985년 7월부터 1989년 7월까지 1∼2개월 간격으로 조사하였다. 전반적으로 용존산소농도가 매년 감소하는 추세를 보이고 있으며, 특히 1988년에는 심층에 무산소층이 형성되어 순환기 직전에는 저층으로부터 15m 높이까지 확대되었다. 이는 1980년대초까지 빈영양호이었던 소양호가 부영양화되고 있음을 보여주는 것이며 무산소층에서는 저층으로부터 용출된 무기인산염과 암모니아의 농도가 매우 높아 앞으로 영양염용출 증가에 의해 소양호의 부영양화는 가속될 것으로 예상된다. 또한 최근 수년간 겨울기온이 높았던 것도 수직혼합을 감소시킴으로써 용존산소 감소에 기여했을 것으로 보인다. 매년여름 수심 10∼20m에서 중층 산소최저층이 나타나고 있는데 이것은 국내 대형 저수지에서의 전형적인 분포형태인 것으로 보인다. 산소최저층이 표층의 혼합층 바로 아래에 형성되고, 수심이 깊어지면서 다시 서서히 산소가 증가하는 것으로 볼때 형성원인은 표층의 수온이 높아 산소비율이 크고 표층의 혼합층까지만 산소가 공급되기 때문인 것으로 보인다. 또한 장마철에 중층으로 유입되는 유입수에 현탁물이 많이 포함되어 있으며 산소최저층은 새로이 형성되는 중간츠으이 상부와 수심이 일치하고 있고 항상 여름의 우기에 형성되는 것으로 보아 우기의 유입수와 관련이 있을 수도 있다. The seasonal and vertical dissolved oxygen distributions were surveyed from July 1985 to July 1989 in a warm monomictic dendritic-shape reservoir, Lake Soyang. DO content showed the general trend of decrease from year to year, implying the advance of eutro· phication. HypoUmnetic anoxic zone began to develop in 1988 reaching upto 15 m from the bottom, which is an epoch·making event in Lake Soyang, well-known as a clear oligotrophich lake until early 1980s. In anoxic zone phosphate and ammonia concentration were very high, and nitrate depleted, which is expected to accelerate eutrophication of Lake Soyang. Insufficient cooling of surface waters in warm winters of 1986 to 1988 seems to have enhanced the DO decrease by reducing the duration of turnover. Metalimnetic 00 minimum layer appearing every late summer at the depth 15∼20m is a remarkable feature of DO distribution which is thought to be the typical pattern in large Korean reservoirs. The mechanism of the formation of metalimnetic oxygen minimum is further to be studied. However, it seems to be caused by the higher rate of oxygen consumption in epilimnion due to high temperature and the oxygen supply limited to only surface mixed layer, since it is formed just below the mixed layer and dissolved oxygen increase gradually in deeper layer. The intermediate current of storm runoff laden with organic debris of terrestrial origin might be the alternative cause.
