EZW 알고리듬을 수행하는 동안 네 가지의 심벌 (POS, NEG, IZ, ZT)을 사용하게 된다. 하지만 POS 또는 NEG 심벌을 가지는 계수들의 하위밴드의 계수들이 모두 ZT 심벌을 가질 경우 도미넌트 계수열을 만드는데 있어서 데이터의 낭비가 심하다. 이러한 단점을 보완하기 위해 여섯개의 심벌(POS, NEG, IPOS, INEG, IZ, ZT)을 이용한 알고리듬이 제안된 바 있다. 하지만 경우에 따라서 4개의 심벌을 이용한 본래의 알고리듬보다 왜곡이 심한 경우가 간혹 발생하게 된다. 본 논문에서는 네 개의 심볼(LS, IS, IZ, ZT)을 이용한 새로운 알고리듬을 제안한다.

This study is conducted to compare the problems affecting dietary habits and health status between a long-term exercise group and non-exercise group of males older than 50 years. Most subjects of the two groups consider regular exercise to be the most important factor for maintaining health, and recognize hypertension as the number one concern. The most common nutritional supplement among subjects is multiple vitamins, and sleeping time range from 6~8 hours. Breakfast fasting rate was 15.9% among non-exercise group (NEG), where overeating and eating out rates were higher among exercise group (EG) when comparing to NEG. Fasting rates of breakfast, and consumption rates of milk and dairy products, vegetables such as kimchi, and fruits and fruit juices are higher among the EG. Overeating and eating out rates are lower among NEG, whereas eating rates of proteins like meat, fish, eggs, beans, fried foods, high-fat meats carbonated drinks, ice cream, and salt intakes are higher. Rates of health, dietary habits, and nutrient intakes are higher among EG. Energy intakes among the two groups were below the standard level, Vitamin $B_2$ intake is low in EG, and folic acid and calcium intakes were higher in NEG. The exercising group care more about health, eating habits and nutrient intakes, and low smoking rates are being observed. Thus, specific dietary improvement programs for adult men, are required, and it is necessary to consider the practice of nutrition education.

The relationship between two interannual climate variabilities and the frequency of tropical cyclone (TC) that landed over the Korean Peninsula (KP) has investigated for the period of 1951-2004. In the analysis of the relationship between KP-landfall TC frequency and the ENSO phase, most TCs of C-14 (TCs that do not pass through mainland China before landing the KP) and C-23 (TCs that pass through mainland China before landing the KP) tended to more land in the warm phase than normal and cold phases. However, TC intensity at landfall was stronger in the cold and normal phases. In the analysis of the relationship between KP-landfall TC frequency and Arctic Oscillation (AO) phase, the TCs of C-14 tended to more land in the positive (POS) phase of AO and the negative (NEG) phase of AO for C-23. It was found that AO index was negatively correlated with the Ni$\tilde{n}$o-3.4 index. And then the TCs of C-14 landed more frequently over the KP in the AO POS - Ni$\tilde{n}$o-3.4 NEG phases and in the AO NEG - Ni$\tilde{n}$o-3.4 POS phases for the TCs of C-23.

Thin stillage and distillers' grains are byproducts remaining after alcohol distillation from a fermented cereal grain mash. Both byproducts are used as energy and protein sources for ruminants. Due to its liquid nature, more than 50% of thin stillage bypasses the rumen. Thin stillage can be fed alone or in combination with distillers' grains. However, a better utilization by beef cattle is anticipated when thin stillage replaces water as a fluid source. Ruminal undegraded protein content of distillers' grains is greatly affected by type of cereal grain and by drying. Corn distillers' grains have a higher ruminal undegraded protein content than wheat distillers' grains while dried distillers' grains have a higher ruminal undegraded protein content than the wet distillers' grains. Wet and dried distillers' grains can replace up to 50% of corn grain in beef cattle diets without affecting animal performance. The estimated NEg of corn distillers' grains for beef cattle ranges from 100 to 169% of that of corn. In general, wet corn distillers' grains have a higher NEg value than dried corn distillers' grains and the addition of thin stillage improves the NEg of distillers' grains. Improved performance of ruminats fed distillers' byproducts can be attributed to high digestible fiber content, improved rumen environment and a shift in organic matter digestion from the rumen to the small intestine.

방사광 가속기의 저장링 진공용기처럼 콘덕턴스가 배기성능을 좌우하는 진공용기에서는 Strip NEG를 사용하여 분산 배기를 함으로서 원하는 평균진공도를 확보할 수가 있다. 일부 연구소에서는 진공용기 자체를 게터로 코팅하여 사용하고 있으나 그 제작비용이 만만치가 않다. 이 연구에서는 쉽게 구할 수 있는 동전모양의 작은 게터를 진공용기 내부에 길이 방향으로 일렬로 배치하여 분산배기가 실제 가능한 지 평가하였다. 게터는 진공용기 자체를 $180^{\circ}C$ 이상 베이크아웃할 때 활성화되도록 하였다. 실험은 단면적 $13cm^2$, 3 m 길이의 압출형 알루미늄 진공용기로 베이크아웃 온도에 따른 진공도 변화를 측정하여 그 성능을 평가하여 보고하고자 한다.

The purpose of the present study was to investigate cardiac damage biomarkers after a triathlon race in elite and non-elite athlete groups. Fifteen healthy men participated in the study. Based on performance, they were divided into elite athlete group (EG: n＝7) and non-elite athlete group (NEG: n＝8). Participants' blood samples were obtained during four periods: before, immediately, 2 hours and 7 days after finishing the race. creatine kinase (CK), creatine kinase-myoglobin (CK-MB), myoglobin, and lactate dehydrogenase (LDH) were significantly increased in both groups immediately after, and 2 hours after finishing the race (p<.05). CK, CK-MB, and myoglobin were completely recovered after 7 days (p<.05). Hematocrit (Hct) was significantly decreased in both groups (p<.05) 7 days after the race. LDH was significantly decreased in the EG (p<.05) only 7 days after the race. Homoglobin (Hb) was significantly decreased in the NEG (p<.05) only 2 hours after the race. Although cardiac troponin T (cTnT) was significantly increased in the EG but not in the NEG 2hours after the race (p<.05), there was no group-by-time interaction. cTnT was completely recovered in both groups 7 days after the race. In conclusion, cardiac damage occurs during a triathlon race and, is greater in elite than in non-elite. However, all cardiac damage markers return to normal range within 1 week.

호밀을 답리작으로 재배시 수량, 일반사료성분과 에너지 함량 및 수량을 질소시비량 및 예취시기에 따른 반응을 요약하면 다음과 같다. 1. 호밀은 질소시비량이 30kg/10a까지 많을수록 청예 및 건물수량이 증가하고 건물률은 감소하였으며 식물체의 엽신과 엽초의 비율은 증가하는 반면 줄기와 이삭의 비율은 감소하였다. 2. 호밀은 질소시비량이 많을수록 단백질, 총가소화양분(TDN), 무기물 및 에너지 함량과 수량이 모두 증가하였으며 ADF(acid detergent fiber) 와 NDF(neutral detergent fiber)의 함량은 감소하고 상대적사료가치가 높아졌다. 3. 질소시비량이 많아지면 예취시기가 늦더라도 전체 조단백질 함량 중에서 가급태 단백질이 차지하는 비율이 크게 낮아지지 않았다. 4. 호밀의 수확적기는 관행사료가치의 관점에서 는 대체로 유숙기 무렵으로 판단되었으나 사료의 에너지 관점에서는 이와 다소 차이가 있었다. 증체에너지(NEG)와 유지에너지(NEM) 면에서 본 수확적기는 개화후기에 높고 관행사료가치보다 10일정도 빨랐으며 에너지추정값(ENE)과 필유에너지(NEL)는 유숙기 무렵으로 같았다.
