In the 21st century, the phenomenon of interaction in between fine art and design has become more increasingly prevalent. In this paper, the author has analyzed the major works of Spanish artist Eva $Armis{\dot{e}}n$ on a cultural criticism perspective, and has proposed a framework for a deeper understating of the artworks, which reflected the characteristics of contemporary art and culture such as deterritorialization of art and design. As a result, it has been found that the main theme of her artworks is about preferred attitude of a human being in relationship with others, unlike daily lives or innocence of childhood which are well-known subjects to the public. Her main female character could have been formed by blending all of her aesthetic reason, and characteristics of this era and cultural elements. It means that the area where the public enjoys the sense of beauty have been extending from the area of the beautiful to the beauty of universality. It has been found that deterriorialization phenomena, which is a characteristic of post-modern art and design work to dismantle an existing order, the repression, appeared in her work. However, several research areas of her works such as relationship between text and image or formative elements or aphorism etc. still have remained to be solved.

Objectives : The purpose of this study is to evaluate the clinical effect of Moxa-Pellet treatment for nasal symptoms and quality of life(QOL) in patients with allergic rhinitis. Methods: Subjects were voluntarily recruited through newspaper and internet advertisement. In this randomized, single blind and controlled study, experimental group (n=19) received real Moxa-Pellet treatment and control group(n=20) received sham Moxa-Pellet treatment for 3 weeks. Acupuncture points used were $LI_4$, $ST_{36}$, $LU_7$, $GV_{14}$ and $GB_{20}$. Patient's nasal symptoms and QOL were assessed before and after 3 weeks treatment by the Nasal Symptom Scores(NSS) and the Medical Outcomes Study 36-Item Short-Form Health Survey(SF-36). Results : The results were as follows; 1. Among items of NSS, Sneezing' Rhinorrhea' Itching scores and Total Nasal Symptom Scores(TNSS) were significantly improved in experimental group after 3 weeks Moxa- Pellet treatment(p<0.05). In control group, there was no significant difference in all items except Headache item of NSS. 2. Among 8 domains of SF- 36, experimental group showed significant difference in Role-Emotional(RE), Mental Health(MH) and Bodily Pain(Bp) after 3 weeks Moxa- Pellet treatment(p<0.05). Control group showed no significant difference in all domains except one domain(Role limitation-physical). Conclusions: These results suggest that Moxa-Pellet treatment can be applicable to improve nasal symptoms and QOL in the patients with allergic rhinitis. Further long tenn studies on the Moxa-Pellets treatment's sustaining power and safety is needed.
This study examined the differences of academic achievement by social status types through sociometry. This study analyzed 201 students in grade 6 in S elementary school. The social status is classified by 7 (popular, average, rejected, aggressive-rejected, submissive-rejected, neglected, controversial) with academic achievement of each type as dependent variables to figure out the relation between social status types and academic achievement. To classify 5 social status types, a sociometry program developed by Ahn, Ie-Hwan (2007) was used, 2 social status types was classified with experimental condition, and its dependent variable was the score by subjects in the mid-term exam of the 1st semester in 2011. The average values of humanities courses (Korean and social studies) and natural science courses (math and science) were compared by both sexes and 7 social status types. The reference group was average group. As a result, as to male students, N type had the highest score both in humanities courses and natural science courses while C type had the lowest score in both groups. As to female students, P, N, C types had the highest score in both groups with similar range while R type had the lowest score in both groups. This result demonstrates that the academic achievement of students had relatively high relevance with social status. and also, suggestion that how teachers can do to enhance the academic achievement of elementary school students.

Methylmercury (MeHg) is an environmental pollutant with neurotoxic effects on the central nervous system. The major exposure route of MeHg to humans is via consumption of fish and shellfish which accumulate the chemical through the food web in an aquatic environment. Hair mercury level is an excellent marker for MeHg exposure. We have been conducting a survey on hair mercury contents among general populations from 14 districts to estimate the current Japanese MeHg exposure level. Total mercury levels of all hair samples collected (12923 in total) were analyzed by the oxygen combustion-gold amalgamation method using an atomic absorption mercury detector. Multiple regression analysis revealed that mercury levels were significantly correlated with several covariates, such as sex, age, the amount of daily intake of total fish/shellfish, a preference for certain fish such as tuna or bonito, and artificial waving. The geometric means for the population without artificial waving were 2.47 and 1.65 ${\mu}g/g$ for males (n = 5623) and females (n = 3470), respectively. Hair mercury levels varied with age, and the variations were more significant in males. Since the difference between sexes was not evident at younger ages, some hormonal control might also be involved in the mercury uptake by human hair. The average mercury levels in our hair samples varied among the sampling districts. Tuna is a major carnivorous fish with high mercury accumulations that is often consumed in Japan. The amount of fish consumption and the preference rate far tuna would appear to be responsible far the regional variation in hair mercury levels in Japan. Recently, a provisional tolerable weekly intake (PTWI) of MeHg was revised by 61st JECFA to 1.6 ${\mu}g/kg/week$, which was about half that of the Japanese standard, and corresponded to a hair level of 2.2 ppm. The distribution of hair mercury levels in Japanese populations in the present study indicated that 25% of the Japanese females of child-bearing age were estimated to be exposed to MeHg over the PTWI level. This would reflect the high Japanese consumption of marine products. However, not only mercury contamination, but also the nutritional benefit may have to be considered when discussing the risk involved in the current level of fish and shellfish consumption in Japan.
Electrochemical synthesis of conductive polypyrrole films was carried out in nucleophilic solvent containing p-toluenesulfonic acid or bezensulfonic acid as supporting electrolyte and dopant. Also characteristics of degradation and improvement of mechanical properties were studied. The conductivity, tensile strength and elongation of the films obtained in dimethyformamide/p-toluenesulfonic acid had the highest value of 10-40S/cm, $25N/mm^2$ and 10%, respectively. The optimum condition of electrochemical synthesis was $2mA/cm^2$ for constant current method and 0.9V for constant potential method containing 0.5M pyrrole and 0.5M p-TSA. The obtained films showed good stability in air and electrode characteristics of secondary battery by reversibility in doping and undoping. The degradation process was 1st order reaction at various temeprature. The activation energy and rate constant of degradation reaction were $1.01JK^{-1}mol^{-1}$ and $3.1{\times}10^{-7}min^{-1}$ respectively at $25^{\circ}C$. For the improvement of mechanical properties, composition of polypyrrole films with various host polymer were investigated and increase of tensile strength and elongation was confirmed.
Clozapine, on atypical antipsychotic drug, has been estimated to be a major improvement in the treatment-refractory schizophrenic patients. We evaluated the clozapine efficacy in the treatment of schizophrenic patients who are refractory to classic neuroleptics. The patients were assigned in a prospective, open, comparative trial for 12 weeks. Following an dose titration, 33 inpatients with treatment-refractory schizophrenia diagnosed according to DSM-III-R were given a clozapine(N=17, approximate 300-600mg/day) or haloperidol(N=16, approximate 20-30 mg/day) for 12 weeks. The clinical state was assessed before treatment, and 1st, 4th, 8th and 12th week during treatment using Brief Psychiatric Rating Scale(BPRS) and Positive and Negative Syndrome Scale(PANSS). Assessment of side effects were mode weekly using Simpson-Angus Scale for Extrapyramidal Side Effects and Adverse Events-Somatic Symptoms. Clozapine produces significant improvement than haloperidol on the BPRS and PANSS scores. 77% (13/17) of the clozapine-treated patients were categorized as responders, who showed at least 20% decrease in total BPRS scores, compared with 31% (5/16) of haloperidol-treated patients. Extrapyramidal side effects occurred in only one patient in clozapine group, but nine patients in haloperidol group. Salivation, sleepiness, constipation and hypotension were most frequent adverse effects observed in clozapine group. There was no significant changes in total WBC and neutrophil during clozapine treatment. These findings suggest that clozapine is on effective antipsychotic drug for the Korean treatment-refractory schizophrenic patients, who are nonresponsive to or unable to tolerate classcal antipsychotic drugs due to extrapyramidal side effects.

A gap between a $Al_2O_3/Fe$ thermite and lower head vessel is formed in the lower-plenum arrested vessel attack(LAVA) experiment which is the 1st phase study of simulation of naturally arrested vessel attack in vessel(SONATA-IV). The gap measurement using a conventional ultrasonic method would be lack of a reliability due to the structure complexity and the metallurgical grain size change of the lower head HAZ occurred by a thermite $Al_2O_3/Fe$ melt or a $Al_2O_3$ melt at $2300^{\circ}C$. The grain echoes having false signals and lower S/N ratio signals are detected due to a multiple scattering, a mode conversion and an attenuation of a ultrasonic resulted from at the interface of increased grain size zone. In this test, the signals pattern was classified to understand the behavior of the ultrasonic in a multi-layer specimen of solid-liquid-solid of assuming that the thermite and the lower head vessel is immersed. The polarity threshold algorithm of frequency diversity gives us the enhancement about 6dB of the ratio S/N.
We evaluated the aquatic ecosystem of Keum-Ho River through applications of the Index of Biological Integrity (IBI) using fish assemblages and Qualitative Habitat Evaluation Index (QHEI) during June-November 1999. Overall IBI values ranged from 13 to 37 with mean of 23 (n=25, Std. error= 1.16), indicating a "Poor" or "Very Poor" condition according to the criteria of Karr (1981) and U.S. EPA (1993). The values of mean IBI declined at the rate of $0.22km^{-1}$(($r^2$=0.91, p< 0.05) along the longitudinal distance from the headwaters to the down-river. Reduced IBI values at down-river (St. 4 and 5) were attributed to the decreases in riffle benthic species and the relative abundance of insectivore and increases in tolerant species, anormalies and exotic species. Spatial pattern in IBI agreed with QHEI values, which showed a linear relation ($r^2$=0.998, p< 0.001) with mean number of species. Field measurements of conductivity and pH, indicators for variation of conservative ions, showed that the river water was diluted up to 30% by summer precipitation and surface run-off from the watershed, resulting in physical and chemical instability during the monsoon. For these reasons, average IBI values during monsoon and postmonsoon decreased more than 20% compared to pre -monsoon. Before the perturbation of the system (i.e., pre-monsoon), values of QHEI were inversely correlated (r=-0.99, p< 0.0001) with realtive abundance of native omnivore and were positively correlated (r=0.87, p=0.05) with relative abundance of native carnivore. These results indicate that spatial degradation of habitat quality modified the species richness and trophic structure, producing decreased IBI values.

In the present study, a dual-band multiple-input-multiple-output (MIMO) antenna covering WLAN frequency bands of 2.4 GHz (2.4 ~ 2.484 GHz) and 5 GHz (5.15 ~ 5.825 GHz) is newly presented to avoid use of decoupling structure for increasing isolation. The antenna consists of two L-shaped slots with n-shaped slots etched on the floating ground plane surrounded by open ended L-shaped slots which are placed in the left and right corner of PCB respectively. The proposed antenna is designed and fabricated on one side of FR4 substrate with dielectric constant of 4.3, thickness of 1.6 mm, and size of $50{\times}50mm2$. It has been observed that the measured impedance bandwidths ($S_{11}{\leq}-10dB$) are 0.3 GHz (2.28 ~ 2.58 GHz) in 2.4 GHz frequency band and 0.89 GHz (5.11 ~ 6 GHz) in 5 GHz frequency band respectively. In addition, It has been observed that the whole efficiency are more than 80 % in the whole operating frequency band and envelope correlation coefficient of the antenna is less than 0.05 as a very small value in spite of nothing of the decoupling structure.
Background: Usually, lumbar epidural block is performed on the $L_{3-4}$ interspace. This study was designed to evaluate the analgesic efficacy and shortening of labor duration comparing the $L_{1-2}$ and $L_{3-4}$ interspace epidural blocks in nulliparous normal vaginal deliveries and then investigates side effects following the blocks. Methods: Eighty healthy nulliparous women were divided into two groups, $L_{1-2}$ (n = 40) and $L_{3-4}$ (n = 40). Epidural blocks, lumbar epidural block were performed at the $L_{1-2}$ and $L_{3-4}$ interspace with a catheter advancing 3 cm cephalad. The initial dose of 12 ml (0.167% bupivacaine, fentanyl $50{\mu}g$ and clonidine $75{\mu}g$) was injected epidurally at 4 cm dilatation of cervix and severe pain of labor. If a visual analogue scale (VAS) score was more than 4 points, an additional dose was administered epidurally using the same volume as the above mentioned, but with the exception that the bupivacaine was diluted to 0.1 percentage. The maternal blood pressure, pulse rate, respiration rate and fetal heart rate were measured at 10 min intervals for the first 30 min, at 15 min interval for the next 30 min and at 30 min interval for the last one hour following the blocks. The duration of the first (active) and second stages of labor was counted and the neonatal Apgar score was recorded at one and five min after delivery. The degree of motor block, pruritus, nausea and vomiting were also noted. Results: The patients in group $L_{1-2}$ had lower pain scores than group $L_{3-4}$ at 5, 20, 30, 60 mins. The duration of 1st and 2nd labor stage in the $L_{3-4}$ epidural block were $272{\pm}33.5$ min, $49.2{\pm}27.4$ min respectively but those in the $L_{1-2}$ epidural block were $253.5{\pm}32.5$ min, $37.3{\pm}22.3$ min, respectively. Conclusions: We concluded the analgesic efficacy and shortening of labor duration in $L_{1-2}$ epidural block was better than those in $L_{3-4}$ epidural block. Maternal hemodynamic change, motor block. pruritus, nausea, vomiting and Apgar score showed no significant differences between the two groups.
