This researcher has sorted out the development process of death aesthetics contained in human art through advanced research. This research is a follow-up study of related research, which studies the aesthetic meaning of death in Alexander McQueen's fashion works. This study first classifies the aesthetic characteristics of death, and then analyzes and sorts out the aesthetics of death in Alexander McQueen's clothing works based on this. The results of this study are as follows: first, the aesthetic manifestations of death are divided into three categories: reproducibility, symbolic and religious. Among them, the representation of reproducibility includes the representation of real objects and the representation of virtual objects, and the symbolic performance includes two types of external performance and internal performance. Second, in Alexander McQueen's works, the reproducibility of death was mainly reflected by virtual stage scenes and costumes. Thirdly, the symbolic death is not only reflected in the skeletons and blood etc. directly related to the death of the body, but also in the various emotions and psychological states caused by the death. Fourth, the religious nature of death was represented in Alexander McQueen's works through such representative things as crosses and religious stories.

The study is to examine relationship between the level of depression and facial EMG responses during the humor condition. Forty-three children(age range 22-49 years) participated in the study. The Korean Personality Inventory for Children(KPI-C) was used to measure the level of depression in children. While children were presented to audio-visual film clip inducing humor, facial EMG were measured on their faces(bilateral corrugators and orbicularis). A baseline state was measured during 60 seconds before the presentation of the stimulus, i.e., emotional state lasting 120 seconds. Participants were asked to report the intensity of their experienced emotion. The results of emotion assessment showed 95.3% appropriateness and 3.81 intensity on the 5 points Likert scale). Facial EMG showed a significant increase while participants experiencing humor compared to baseline state. Additionally, the result showed a negative correlation between right corrugator responses and the level of depression. The study findings showed the more children experienced depression, the less facial EMG activity they had while experiencing humor.

The purpose of this paper is to investigate the adequate clothing pressure of upper and lower body foundation garment and subjective assessment of those compressive foundation depending on various wearing conditions. Eighteen women in their 30s and 40s participated in the experiments for this study to evaluate the level of clothing pressure of girdle and waist nipper. Subjects were divided into two groups by the wearing habits of foundation, one is the group of wearing foundation garment 'tightly' and the other is 'loosely', It was found that the group wearing foundation garment 'loosely' was much more sensitive than the group of 'tightly' in everyday life. The adequate pressure of upper foundation, waist nipper was about $1.5{\pm}0.8$ kPa which is lower than that of the lower body foundation, girdle. And at the same time, the sensitivity of the pressure level was higher when subjects are wearing waist nipper compared with wearing girdle. Therefore, precise pattern making process is necessary to meet the adequate level of pressure of the upper body foundation such as waist nipper, specially for those who used to wear clothing loosely.

Fetal heart rate monitoring is important information to assess fetal well-being. Non-invasive fetal ECG (electrocardiography) can be derived from maternal abdominal signal. And various promising signal processing methods have been introduced to extract fetal ECG from mother's composite abdominal signal. However, non-invasive fetal ECG monitoring still has not been widely used in clinical practice due to insufficient reliable measurement and difficulty of signal processing. In application of signal processing method to extract fetal ECG, it might be lower signal to noise ratio due to time varying white Gaussian noise. In this paper, time varying Kalman smoother is proposed to remove white noise in fetal ECG and its feasibility is confirmed. Wiener process was set as Kalman system model and covariance matrix was modified according to white Gaussian noise level. Modified error covariance matrix changed Kalman gain and degree of smoothness. Optimal covariance matrix according to various amplitude in Gaussian white noise was extracted by 5 channel fetal ECG model, and feasibility of proposed method could be confirmed.

The aim of this study was to determine the chemical and intracellular antioxidant activities of ${\beta}$-carotene and lycopene and to compare their quantitative structure-activity relationship (QSAR). In our previous study, the second ionization energy of lycopene was higher than that of ${\beta}$-carotene, as calculated by QSAR. Chemical antioxidant activities of ${\beta}$-carotene, lycopene, and Trolox were examined by measuring ferric reducing antioxidant power (FRAP) and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. Intracellular antioxidant activities were evaluated by intracellular reactive oxygen species (ROS) and DNA fragmentation. The FRAP of lycopene was higher than that of ${\beta}$-carotene (P<0.05), and the two carotenoids had similar antioxidant activities in DPPH radical scavenging activity assay. Trolox had the greatest chemical antioxidant activities (P<0.05). When RAW264.7 cells were treated with lipopolysaccharide (LPS) (100 ng/mL) for 20 h, intracellular ROS and DNA fragmentation significantly increased (P<0.05). RAW 264.7 cells pretreated with ${\beta}$-carotene ($4{\mu}M$) and lycopene ($0.4{\sim}2{\mu}M$) for 4 h formed significantly less intracellular ROS than LPS-treated control cells (P<0.05), whereas cells with Trolox did not reduce production of intracellular ROS. In addition, cells pretreated with $2{\mu}M$ lycopene produced less intracellular ROS than those treated with ${\beta}$-carotene (P<0.05). DNA fragmentation of cells with ${\beta}$-carotene and lycopene was similar to that of LPS-treated control cells as measured by Hoechst staining. The antioxidant ability of lycopene was greater than that of ${\beta}$-carotene in the QSAR, FRAP, and intracellular ROS assays (P<0.05). ${\beta}$-Carotene and lycopene had lower antioxidant activities as measured by FRAP (P<0.05) but higher intracellular protective effects against LPS-induced oxidative stress in comparison with Trolox.

Occurrence of Cochlodinium polykrikoides red tides have resulted in considerable economic losses in the aquaculture industry in many countries, and thus predicting the process of C. polykrikoides red tides is a critical step toward minimizing those losses. Models predicting red tide dynamics define mortality due to predation as one of the most important parameters. To investigate the roles of heterotrophic protists in red tide dynamics in the South Sea of Korea, the abundances of heterotrophic dinoflagellates (HTDs), tintinnid ciliates (TCs), and naked ciliates (NCs) were measured over one- or two-week intervals from May to Nov 2014. In addition, the grazing impacts of dominant heterotrophic protists on each red tide species were estimated by combining field data on red tide species abundances and dominant heterotrophic protist grazers with data obtained from the literature concerning ingestion rates of the grazers on red tide species. The abundances of HTDs, TCs, and NCs over the course of this study were high during or after red tides, with maximum abundances of 82, 49, and $35cells\;mL^{-1}$, respectively. In general, the dominant heterotrophic protists differed when different species caused red tides. The HTDs Polykrikos spp. and NCs were abundant during or after C. polykrikoides red tides. The mean and maximum calculated grazing coefficients of Polykrikos spp. and NCs on populations of co-occurring C. polykrikoides were $1.63d^{-1}$ and $12.92d^{-1}$, respectively. Moreover, during or after red tides dominated by the phototrophic dinoflagellates Prorocentrum donghaiense, Ceratium furca, and Alexandrium fraterculus, which formed serial red tides prior to the occurrence of C. polykrikoides red tides, the HTDs Gyrodinium spp., Polykrikos spp., and Gyrodinium spp., respectively were abundant. The maximum calculated grazing coefficients attributable to dominant heterotrophic protists on co-occurring P. donghaiense, C. furca, and A. fraterculus were 13.12, 4.13, and $2.00d^{-1}$, respectively. Thus, heterotrophic protists may sometimes have considerable potential grazing impacts on populations of these four red tide species in the study area.

The physicochemical characteristics and antioxidant activities of Lentinula edodes cultivated with liquid spawn were compared according to the harvest cycle (1-3 cycles). There was no significant difference in moisture content. The crude lipid and crude protein contents tended to decrease according to harvest cycle. The content of β-glucan was the highest in mushrooms after one cycle. The β-glucan content in cycles 2 and 3 was 68.5% and 62.3% that of the content after cycle 1, respectively. Mineral content in the pileus and stipe was similar. The mineral content was highest in the pileus after two cycles. Composition and contents of free amino acids tended to decrease according to the harvest cycle. Contents of essential amino acids were higher in mushroom after one cycle. Total phenol content was highest in the pileus (31.96 mg/100 g) and the stipe (21.10 mg/100 g) after one cycle and tended to decrease with subsequent cycles. The flavonoid content was 11.13 mg/100 g after one cycle and significantly decreased according to the harvest cycle. Antioxidant activities were also highest after one cycle and significantly decreased according to the harvest cycle. When compared to L. edodes cultured for one cycle, L. edodes cultivated with liquid spawn for three cycles was considered to have similar marketability in terms of quality characteristics.

This study investigated the effects of recombinant eel gonadotropin hormone (rJeGTH) produced in silkworms, with and without a carboxyl-terminal peptide from equine chorionic gonadotropin (eCG), on the induction of sexual maturation in female eels Anguilla japonica. Experiments were conducted both in vivo and in vitro. In in vitro trials, germinal vesicle breakdown (GVBD) induction did not significantly differ between rJeFSH and $rJeFSH{\cdot}eCG$ treatments and the control group. However, previous studies did find that rJeLH and $rJeLH{\cdot}eCG$ treatments induced GVBD in female eels. Our in vitro exploration of $estradiol-17{\beta}$ ($E_2$) levels in immature ovarian tissues revealed significantly higher $E_2$ levels in the group treated with $rJeFSH{\cdot}eCG$ $1{\mu}g/mL$ than in the control group. In contrast, the in vivo experiments showed no effect of recombinant hormones on the sexual maturation of feminized eels. Previous studies and our own in vitro results have clearly shown that rJeGTH and $rJeGTH{\cdot}eCG$ have a positive effect on the sexual maturation of feminized eels. To develop the activity of rJeGTH in vivo, further studies should confirm circulation time and activity of these hormones in eels' bloodstream, modify the structure of the recombinant gene, and implement additional glycosylation.
