We address the problem of uncooperative person recognition through continuous monitoring. Multiple modalities, such as face, height, clothes color, and voice, can be used when attempting to recognize a person. In general, not all modalities are available for a given frame; furthermore, only some modalities will be useful as some frames in a video sequence are of a quality that is too low to be able to recognize a person. We propose a method that makes use of stochastic information updates of temporal modalities and environment estimators to improve person recognition performance. The environment estimators provide information on whether a given modality is reliable enough to be used in a particular instance; such indicators mean that we can easily identify and eliminate meaningless data, thus increasing the overall efficiency of the method. Our proposed method was tested using movie clips acquired under an unconstrained environment that included a wide variation of scale and rotation; illumination changes; uncontrolled distances from a camera to users (varying from 0.5 m to 5 m); and natural views of the human body with various types of noise. In this real and challenging scenario, our proposed method resulted in an outstanding performance.

Objective: This study investigated the effect of different acute heat stress (HS) levels on chicken meat quality and ultra-structure. Methods: Chickens were randomly divided into 7 groups to receive different HS treatments: i) $36^{\circ}C$ for 1 h, ii) $36^{\circ}C$ for 2 h, iii) $38^{\circ}C$ for 1 h, iv) $38^{\circ}C$ for 2 h, v) $40^{\circ}C$ for 1 h, vi) $40^{\circ}C$ for 2 h, and vii) un-stressed control group ($25^{\circ}C$). Blood cortisol level, breasts initial temperature, color, pH, water holding capacity (WHC), protein solubility and ultra-structure were analyzed. Results: HS temperatures had significant effects on breast meat temperature, lightness ($L^*$), redness ($a^*$), cooking loss and protein solubility (p<0.05). The HS at $36^{\circ}C$ increased $L^*{_{24h}}$ value (p<0.01) and increased the cooking loss (p<0.05), but decreased $a^*{_{24h}}$ value (p<0.05). However, as the temperature increased to $38^{\circ}C$ and $40^{\circ}C$, all the values of $L^*{_{24h}}$, cooking loss and protein denaturation level decreased, and the differences disappeared compared to control group (p>0.05). Only the ultimate $pH_{24h}$ at $40^{\circ}C$ decreased compared to the control group (p<0.01). The pH in $36^{\circ}C$ group declined greater than other heat-stressed group in the first hour postmortem, which contributed breast muscle protein degeneration combining with high body temperature, and these variations reflected on poor meat quality parameters. The muscle fiber integrity level in group $40^{\circ}C$ was much better than those in $36^{\circ}C$ with the denatured position mainly focused on the interval of muscle fibers which probably contributes WHC and light reflection. Conclusion: HS at higher temperature (above $38^{\circ}C$) before slaughter did not always lead to more pale and lower WHC breast meat. Breast meat quality parameters had a regression trend as HS temperature raised from $36^{\circ}C$. The interval of muscle fibers at 24 h postmortem and greater pH decline rate with high body temperature in early postmortem period could be a reasonable explanation for the variation of meat quality parameters.

Many of our contemporaries suffer from the symptoms of phlegm-fire, which is caused by stress, processed food, heavy diet, and unseasonal fruits and vegetables. With consultations from 'Euihaklpmoon', 'DongeuiBogham', and 'Ji-San's clinical lectures' this research, which is mainly focused on phlegm-fire, concluded as following. Phlegm-fire is caused by congestion of seven emotions, congestion of qi, complication of phlegm on fire, depletion of body fluids after long periods of disease, heavy diet, or congenital unbalance of yin-yang and qi-hyul. Concentration of phlegm-fire on the head causes headache, dizziness, frontal headache, tinnitus, and auditory dysfunction. The patient usually complains breaking pain. Dhamhwabang of Yijin-tang, Chunghoonhwadham-tang, and Yijin-tang variation for right headache can be used. Concentration of phlegm-fire on the thorax causes insomnia, palpitation, and insanity. Samhoohndham-tang variation, Chungsimgondhanhwan can be used. Concentration of phlegm-fire on the gastric region causes reflux of gastric acid, eructation, vomiting, abdominal discomfort, dysmenorrhea, and fluor gentalis. Yijin-tang variation for abdominal discomfort, Yanghyulsamul-tang, Hwadhamchunghwa-tang can be used. Shin type or Gi type, female with prevalence of qi and tendency of fire, female with dark facial color, female with raised eye tails and large noses, female with pointed noses, and male or female with large noses and mouths are likely to possess phlegm-fire. Abdominal discomfort of male with thick eyebrow and headache of Gi type female is usually caused by phlegm-fire.

본 연구는 제주마의 기본모색 분류체계와 유전 변이간의 관계를 확인하기 위해 수행되었다. pyrosequencing 방법을 이용하여 melanocortin receptor 1 (MC1R)과 agouti signaling protein (ASIP) 유전자의 변이를 분석하였다. MC1R은 g.901C>T 염기치환을 분석하였고, ASIP는 11-bp 결실돌연변이를 분석하였다. 가라마필은 MC1R에서는 $E^+$/- ($E^+/E^+$ or $E^+/E^e$), ASIP에서는 $A^a/A^a$ 유전자형이 나타났다. 유마 마필에서는 MC1R은 $E^+$/- 그리고 ASIP는 $A^A$/- 유전자형이 나타났다. 반면에 적다 마필에서 MC1R은 $E^e/E^e$ 유전자형만이 나타났으며, ASIP에서는 모든 조합의 유전자형이 나타났다. 가라모색과 유마모색은 MC1R에서 적어도 1개의 $E^+$ 우성대립유전자를 갖고 있어야하며, 적다모색에서는 동형열성대립유전자인 $E^e/E^e$ 유전자형을 가져야 한다. 이는 ASIP 유전자형 분포와 관계없이 MC1R 유전자형에 의해 가라/유마모색과 적다모색을 결정하는 것이다. 또한 MC1R은 $E^+$/- 그리고 ASIP은 우성대립유전자인 $A^A$/-를 갖는 마필은 유마모색을 나타내는데 이는 ASIP은 우성대립유전자인 $A^A$에 의해 사지를 제외한 부분에서 흑모색발현을 억제하는 것으로 추정된다. 가계분석에서는 제주마와 더러브렛간에 교배로 생산된 $F_1$ 자마의 기본모색 양상과 MC1R 및 ASIP 유전자형 분포와의 관계에 대해 일정한 결과를 보여주고 있다. 본 결과는 모색에 대한 표현형과 유전양상 간의 관계를 보여주고 있으며, 제주마의 분자육종을 위한 중요한 정보를 제공할 수 있을 것으로 사료된다.

Effects of dietary carotenoids were investigated on metabolism of the carotenoids, and body pigmen tation in oily bittering, Acheilognathus koreensis. Two weeks later after depletion,oily bitterings were fed the diets supplemented with either lutein, cynthiaxanthin and astaxathin for 4 weeks. Carotenoids distributed to and metabolized in integument were analyed. The carotenoid isolated from the integument of wild oily bittering, composed of 47.2% zeaxanthin, 11.4% lutein epoxide, 11.0% diatoxanthin, 9.7% lutein and 8.3% zeaxanthin epoxide. Meanwhile, two weeks later after depletion, the carotenoid composed of 29.9% crytoxanthin, 19.3% zeaxanthin, 13.2% lutein epoxide, 12.0% diatoxanthin and 8.8% zeaxanthin epoxide. These indicated that zeaxanthin, diatoxanthin, lutein epoxide and zeaxanthin epoxide were actively metabolized in oily bittering, compared to that of other fresh water fish. Total carotenoid content in the integument of wild oily bittering and oily bittering depleted for two weeks was found to be 1.72mg% and 2.08mg%, respectively. Two weeks later after treatment of experimental diet, total carotenoids content was increased to 2.23mg% in lutein, 2.36mg% in cynthiaxanthin and 2.49mg% in astaxanthin supplemented group, which were relatively higher than 2.10mg% in control group. Meanwhile, 4 weeks later, total ca rotenoids content was decreased to 1.76mg% in control, 1.95mg% in lutein, 1.74mg% in cynthiaxanthin and 1.72mg% in astaxanthin supplemented groups. These result indicate that dietary carotenoids were rapidly accumulated and then metabolized to certain metabolites shortly after feeding. Body pigmentation effects of the carotenoids due to accumulation of carotenoids in the integument of oily bittering was the most effectively shown in the astaxanthin supplemented group, followed by cynthiaxanthin and lutein supplemented groups. In the integument of oily bittering, dietary carotenoids were presumably biotrans formed via either oxidative or reductive pathways as presumed the variation of total carotenoid content and carotenoid composition in all experimental groups. The lutein was oxidized either to astaxanthin via doradexanthin and doradexanthin, or to zeaxanthin epoxide via zeaxanthin by oxidative pathway. Cynthiaxanthin was converted either to diatoxanthin and zeaxanthin by reductive pathway and then to zeaxanthin epoxide by oxidative pathway, or it was converted to astaxanthin via diatoxanthin, zeaxan thin and doradexanthin by oxidative pathway. Astaxanthin was converted to doradexanthin and zeaxanthin by reductive pathway and then to zeaxanthin epoxide by oxidative pathway. These results suggest that, oxidative pathway of carotenoids was major metabolic pathway along with reductive path way in fresh water fish.

암컷의 배우자 선택은 여러 수컷들이 가지고 있는 다양한 특성에서 각기 다른 종류의 정보를 수집, 종합하여 가장 최적의 개체를 배우자로 결정하는 매우 복잡한 행동이다. 본 연구에서는 순차적인 교배 시스템($4{\times}4$ block breeding)을 이용하여 각시붕어(Rhodeus uyekii) 암컷의 배우자 선택방식을 조사하였고, 가중과 비가중 유전적 이득의 상대적 기여도를 추정해 보고자 하였다. 실험장치 내에서 총 48회의 암, 수간 배우자 상호작용이 관찰되었고, 암컷은 일반적으로 카로티노이드 혼인색 발현이 강한 수컷들을 배우자로 선호하는 것으로 나타났다. 하지만, 배우자 선호 정도가 개체에 따라 차이가 나타나므로, 비가중적 요소도 암컷이 배우자를 선택하는데 있어 기여를 할 것으로 예상된다.

쏨뱅이아목 (Scorpaenoidei) 어류에 속하는 꼼치과 (Liparidae) 어류는 형태적으로 유사하고 오동정 가능성이 크며 체색과 몸의 상대적인 크기 변이가 심하여 분류학적으로도 상당히 혼란스러운 분류군이다. 따라서, 본 연구는 꼼치과 어류의 자원변동을 이해하고 자원관리를 위해 국내 보고된 3속 10종을 대상으로 분자계통 및 분류학적 재검토를 수행하였다. 미토콘드리아DNA COI 영역과 핵DNA RAG2 영역의 염기서열을 이용한 분자계통 분석 결과, 물미거지가 분홍꼼치와 가깝게 유집되는 mtCOI 계통 결과를 제외하면 3속 (분홍꼼치속, 물미거지속, 꼼치속)이 대등한 단계통성을 나타내었다. Gilbert and Burke (1912)는 L. ochotensis와 구분되는 한국산 미거지를 L. ingens로 신종 보고하였으나, 본 연구에서 한국산 미거지는 일본산 및 러시아산 L. ochotensis와 형태 및 분자에서 잘 일치하였으므로 한국산 미거지의 학명을 L. ingens에서 L. ochotensis로 변경한다.

Physical, chemical and biological surveys on Nakdong River estuary were made from October, 1985 to September, 1986. 1. For all the seasons except summer, the sea surface temperature in northwest area of the line which linked from Seo Island to Jisim Island was I-2$^{\circ}$C lower than in southeast area, but in summer the sea surface temperature in northwest area was I-2$^{\circ}$C higher than in southeast area. On the contrary, bottom temperature of coastal area was 1$^{\circ}$C higher than that of oceanic area except winter. 2. Surface salinity in summer and fall has minimum value of 1. 9%0 and maximum value of 32.9%0. This large variation was caused by the runoff of the Nakdong River. Effect of less saline Nakdong River water in northwest area of the line which linked from Seo Island to Jisim Island was greater than in southeast area. A strong current rip always formed near this line. 3. The yellowish-green colored zone was observed in the Nakdong River estuary throughout the year by influence of river discharge. The characteristics of the water quality in the zone have shown that the water color was grade 7 by the Forel water-color meter, transparency was less than 4 m, and concentration of suspended solids was more than 5 mg/1. This water body was in the state of eutrophication in terms of chlorophyll-a and inorganic nitrogen concentration during summer season. 4. During the study period, total 276 taxa were identified. Most of them were diatoms and dinoflagellates which consisted of 97.5%. The component ratio of the above two groups was 84.4% and 13.1 % respectively. Diatoms were plentiful in December and dinoflagellates in July. Dominant species were Nitzschia seriata in October, Thalassiosira rotula in December, Skeletoncma costatum in April, and Nitzschia longissima in July. 5. A total of 47 zooplankton taxa was identified from the samples collected. Copepods were numerically the most important components of zooplankton communities in the study area. The domir:ant copepod species were Paracalanus parvus, Acartia clausi and Temora turbinata. Noctiluca scintillans was the next important component. The other zooplankton with minor abundance were Cladocera. Sagitta spp., Cnidaria, Mysidacea, Lucifer spp. and Amphipoda. 6. During the study period, fishes from 47 families and 87 species were sampled in th~ study area. The four most abundant fish species were Rep~mucen//'s valencicnnei, Leiognathus n~cha!is, Amblychaeturicllthys hexanema and Sardirel/a zun:zsi. The fish species of the secondary importance in abundance were Cynoglossus joyneri, Sillago sihama, Engra~lis japonicus, Encdrias nebulos'l, Acanthogobius flavimanus, Trichiurus lepturus, LiParis tanai/ai, Cynagloss//'s interruptus, Aj)ogon line:z!us, Thrissz la 1l.'1la!ensis, and Limanda yokohamac.
