The purpose of this study was to evaluate the changes on the characteristics of the oxidative stability of Tenebrio molitor larvae during cold storage at $4^{\circ}C$. Pretreatment for T. molitor larvae was designed into three methods: raw (R), freeze-dried (F.D.), and pan-fried (P.F.). The water content of the raw sample (61.46%) was higher than those of other samples (F.D.: 5.02%, P.F.: 3.67%) and its high water content was expected to facilitate the oxidation of the raw sample. In our results, the peroxide value and the carbonyl value of all of the samples increased and the raw sample, after storage for 18 day, showed the highest value. The pan-fried sample had no significant increase in its lactic acid content, acid value, and thiobarbituric acid value; whereas those values were increased in the raw sample and the freeze-dried sample (p<0.05). The browning reaction was more progressed in the pan-fried sample than other samples at 0 day, but there was no significant change during the storage. The raw sample and the freeze-dried sample had their browning indexes increase with the increasing storage period (p<0.05). The pan-fried sample produced less oxidation products than the freeze-dried sample, indicating that the unheated sample was more susceptible to oxidation than the heated samples. In conclusion, heating treatment and low water content would be effective for improving the safety and stability of T. molitor larvae during cold storage.

Objectives : Little is known about the physician-related factors that are associated with the management of Hypertension. The purpose of this study was to determine the physician-related factors associated with blood pressure control in hypertensive patients. Methods : We surveyed 154 physicians at 117 public health (subhealth) centers in Gyeonggi-do, Forty-one physicians completed the survey (response rates : 26.6%) and 31 physicians were finally included as the study subjects. Using the information obtained from the self-reported survey, we measured the physician-related factors associated with hypertension control, including their perception of hypertension, prescription patterns (combination prescription rates, specific antihypertensives prescription rates among patients with diabetes mellitus), and sociodemographic factors. We then collected data on blood pressure and medication use in patients seen by these physicians from the health center#s information system. We compared the physicians# perceived hypertension control rates with the actual rates, and then evaluated the rate of high overestimation (overestimation by more than 25% of the median degree of hypertension control rate overestimation) among the physicians. The physicians# antihypertensive prescription patterns were also evaluated. Multiple logistic regression analysis was used to evaluate the independent association between hypertension control and physician-related factors. Results : The physicians tended to overestimate the proportion of their patients with controlled blood pressure (79.5% perceived vs. 57.8% actual). The percentage of physicians with high overestimation was 35.5% (11 physicians). The physicians with lower control rates were more likely to highly overestimate their patients# control rates. Physicians with below-median actual control rates tended to prescribe fewer combination treatments for patients with uncontrolled blood pressure and angiotensin-converting enzyme inhibitors or fewer angiotensin receptor blockers for patients with diabetes mellitus. The rate of high overestimation by physicians was 1.31 times higher in patients with uncontrolled blood pressure than in patients with other conditions (OR=1.31, 95% CI : 1.17-1.48). Conclusions : Physicians have a tendency to overestimate the rates of hypertension control in their patients. Because physicians have a direct role in treatment outcomes, physicians# overestimation about hypertension management contributes to inadequate blood pressure control. Thus, interventions for improving physician# awareness regarding the management of patients with hypertension are needed.

n-6계 linoleic acid의 함량이 높은 옥수수유 및 n-3계 linolenic acid의 함량이 높은 들깨유와 함유된 다가불포화지방산을 공역이중결합 유도체화 처리한 옥수수유 및 들깨유가 흰쥐의 혈청 지질개선에 미치는 영향을 비교 검토하기 위하여 S.D.계 숫 흰쥐에게 돈지 식이를 대조군으로 하고 옥수수유 10%, 들깨유 10%, 유도체화 처리한 옥수수유 10% 및 유도체화 처리한 들깨유 10%을 급여하여 4주간 실험 사육한 후 혈청 지질성분을 분석하였다. 유도체화 처리한 옥수수유(TCO)는 가스 크로마토그래피에 의해 3개의 linoleic acid의 유도체가 확인되었고 유도체화 처리한 들깨유(TPO)에서는 5개의 linolenic acid의 유도체가 확인되었다. 체중증가량 및 식이섭취량은 유도체화 처리한 옥수수유 및 들깨유 급여군에서 유의성 있게 낮았다. 혈청 총콜레스테롤 농도는 대조군에 비해 전실험군에서 유의성 있게 낮았으며, 특히 유도체화 처리한 옥수수유 및 들깨유 급여군에서 더욱 낮았다. HDL-콜레스테롤 농도는 대조군에 비해 전실험군에서 유의적으로 높았다. 혈청 LDL 및 LDL-콜레스테롤 농도는 대조군에 비해 전실험군에서 유의성 있게 낮았으며 유도체화 처리한 옥수수유 및 들깨유 급여군에서 더욱 낮은 경향을 보였고, 특히 유도체화 처리한 들깨유 급여군에서 가장 낮았다. VLDL 농도는 대조군에 비해 전실험군에서 유의성 있게 낮았으며, chylomicron 농도는 유도체화 처리한 유지 급여군에서 유의성 있게 낮았고 특히 유도체화 처리한 들깨유 급여군에서 가장 낮았다. 혈청 유리콜레스테롤 농도는 대조군에 비해 전 실험군간에 유의적인 차이는 없는 반면 유도체화 처리한 옥수수유 및 들깨유 급여군에서 약간 낮았다. 혈청 중성지질 농도는 대조군에 비해 전실험군에서 유의성 있게 낮았으며, 특히 유도체화 처리한 들깨유 급여군에서 가장 낮았다. 인지질 농도는 옥수수유 급여군이 대조군에 비해 약간 높게 나타난 반면 유도체화 처리한 유지 급여군은 약간 낮은 수준이었다. 이상의 결과 n-6계 linoleic acid의 함량이 높은 옥수수유 및 n-3계 linolenic acid 함량이 높은 들깨유의 공역이중결합유도체의 섭취는 혈중 총콜레스테롤, LDL-콜레스테롤, chylomicron 및 중성지질 농도를 감소시킴으로써 혈청 지질 개선효과가 있는 것으로 나타났으며, 특히 n-3계 들깨유의 공역이중결합 유도체 급여군이 혈청 지질 개선효과가 가장 큰 것으로 나타났다. This study was designed to examine the effects of n-6 PUFA rich corn oil, n-3 PUFA rich perilla oil and their conjugated double bond derivatives on serum lipids status in rats. Experimental diets containing lard (control), corn oil (CO), perilla oil (PO), conjugated double bond derivatives of n-6 PUFA rich corn oil (TCO) and n-3 PUFA rich perilla oil (TPO) at the level of 10% (w/w) were fed to male Sprague Dawley rats for 4 weeks. TCO was found to have three derivatives of linoleic acid and TPO had five derivatives of linolenic acid by GC. Serum total cholesterol levels were significantly lower in the all experimental groups than in the control group, and particularly, the lowest in TCO and TPO groups. HDL-cholesterol concentrations were a little higher in the all experimental groups than in the control group, and TCO and TPO groups were not significantly different from CO and PO groups. Serum LDL, LDL-cholesterol, chylomicron and triglyceride concentrations were significantly lower in the all experimental groups than in the control group, remarkably lower in TCO group and particularly, the lowest in the TPO group. Serum free cholesterol and cholesteryl ester concentrations were lower in TCO and TPO groups than in CO and PO groups. From the above research, TCO and TPO groups were effective on the improvement of the lipid compositions in serum and particularly, TPO group was the most effective on the improvement of serum lipids.

We report on the fabrication and characterization of a novel $Cu_2O/CuO$ heterojunction structure with CuO nanorods embedded in $Cu_2O$ thin film as an efficient photocathode for photoelectrochemical (PEC) solar water splitting. A CuO nanorod array was first prepared on an indium-tin-oxide-coated glass substrate via a seed-mediated hydrothermal synthesis method; then, a $Cu_2O$ thin film was electrodeposited onto the CuO nanorod array to form an oxide semiconductor heterostructure. The crystalline phases and morphologies of the heterojunction materials were examined using X-ray diffraction and scanning electron microscopy, as well as Raman scattering. The PEC properties of the fabricated $Cu_2O/CuO$ heterojunction photocathode were evaluated by photocurrent conversion efficiency measurements under white light illumination. From the observed PEC current density versus voltage (J-V) behavior, the $Cu_2O/CuO$ photocathode was found to exhibit negligible dark current and high photocurrent density, e.g. $-1.05mA/cm^2$ at -0.6 V vs. $Hg/HgCl_2$ in $1mM\;Na_2SO_4$ electrolyte, revealing the effective operation of the oxide heterostructure. The photocurrent conversion efficiency of the $Cu_2O/CuO$ photocathode was estimated to be 1.27% at -0.6 V vs. $Hg/HgCl_2$. Moreover, the PEC current density versus time (J-T) profile measured at -0.5 V vs. $Hg/HgCl_2$ on the $Cu_2O/CuO$ photocathode indicated a 3-fold increase in the photocurrent density compared to that of a simple $Cu_2O$ thin film photocathode. The improved PEC performance was attributed to a certain synergistic effect of the bilayer heterostructure on the light absorption and electron-hole recombination processes.

Objectives : The purposes of this study is to estimate the cost of cancer care after its diagnosis and to identify factors that can influence the cost of cancer care. Methods : The study subjects were patients with an initial diagnosis one of four selected tumors and had their first two-years of cancer care at a national cancer center. The data were obtained from medical records and patient surveys. We classified cancer care costs into medical and nonmedical costs, and each cost was analyzed for burden type, medical service, and cancer stage according to cancer types. Factors affecting cancer care costs for the initial phase included demographic variables, socioeconomic status and clinical variables. Results : Cancer care costs for the initial year following diagnosis were higher than the costs for the following successive year after diagnosis. Lung cancer (25,648,000 won) had higher costs than the other three cancer types. Of the total costs, patent burden was more than 50% and medical costs accounted for more than 60%. Inpatient costs accounted for more than 60% of the medical costs for stomach and liver cancer in the initial phase. Care for latestage cancer was more expensive than care for early-stage cancer. Nonmedical costs were estimated to be between 4,500,000 to 6,000,000 won with expenses for the caregiver being the highest. The factors affecting cancer care costs were treatment type and cancer stage. Conclusions : The cancer care costs after diagnosis are substantial and vary by cancer site, cancer stage and treatment type. It is useful for policy makers and researchers to identify tumor-specific medical and nonmedical costs. The effort to reduce cancer costs and early detection for cancer can reduce the burden to society and improve quality of life for the cancer patients.

김소영,이남택,최명자,Kim, So Yeong,Lee, Nam Taek,Choe, Myeong Ja Korean Chemical Society 2001 Bulletin of the Korean Chemical Society Vol.22 No.9

The specificity of conjugation site for coating ligands was investigated using toluene-bovine serum albumin (BSA) conjugates in which BSA was conjugated at the position of o-, m-, and ${\rho}-toluic$ acid. Toluene-BSA conjugated at ${\rho}-position$ showed a binding activity of about 89-95%, whereas, those conjugated at o- and m-position of toluene exhibited a binding activity of 5 and 11%, respectively. On the basis of the above result, coating ligands with various proteins (OVA, BSA, KLH) were compared by conjugating with $\rho-toluic$ acid, and toluene-KLH was considered as the best coating ligand for this ELISA. Indirect competitive ELISA method was developed using anti-toluene antibody and $\rho-position$ conjugated toluene-KLH. The dose-response curve constructed after kinetic and optimization studies showed a 1${\times}$10-4 - 1${\times}$102 mM detectable response range with 0.1 ${\mu}M$ detectability. In specificity test of the antibody, the binding capabilities of aromatic compounds substituted with nitro-, alkyl-, chloro-, and hydroxyl group were larger rather than those of aromatic compounds (benzene, toluene and xylene) themselves. Also, tests with soil and water samples that had been spiked with toluene resulted in 102.7-113.7% recovery.

본 연구는 현재 올레핀/파라핀 분리에서 사용되는 극저온 분리법을 대체하기 위한 촉진수송 분리막에 대한 연구이다. 촉진수송 분리 막을 상업화하기 위해서는 비용 절감 또한 매우 중요한 요소이다. 하지만 많은 연구가 이루어지고 있는 AgBF4는 상대적으로 고가인 은 염이기 때문에 이를 대체하기 위해 비교적 저렴한 AgCF3SO3를 이용하여 PEBAX-2533/AgCF3SO3/Al(NO3)3 복합막을 제조하였다. 분리막의 특성은 SEM, FT-IR, RAMAN을 통해 분석되었으며, 이번 연구를 통해 고분자 매트릭스가 장기 안정성에 영향을 준다는 사실을 확인하였다. This study was a study on an facilitated transport membrane to replace the cryogenic separation method currently used in olefin/paraffin separation. Cost reduction is also a very important factor to commercialize facilitated transport membranes. However, AgBF4, which has been studied a lot, is a relatively expensive silver salt. To replace this, a PEBAX-2533/ AgCF3SO3/Al(NO3)3 composite film was prepared using relatively inexpensive AgCF3SO3. It was analyzed through SEM, FT-IR, and RAMAN. Through this study, it was confirmed that the polymer matrix affects the long-term stability.

This research investigated the effects of cool touch fabrics on thermo-regulating physical properties and subjective evaluation using a 3D fitted women's T-shirts in wear test. Qmax, clothing microclimate, microclimate wettedness, thermogram and subjective vote were observed during rest-right after an exercise-rest protocol. As a result, there was no single determining physical variable to explain the reasons of cool sensations of T-shirts made of cool touch fabric across the entire protocol. Qmax could partly predict a wear sensation at the initial stage when only insensible perspiration was presented. Simultaneous observation of temperature/humidity gradient understand from the inside to the outside of the clothing layer or microclimate wettedness calculated using vapor pressure were helpful to figure out the performance of cool touch fabric, especially at the later stage of the protocol when sweating was excessive. It was especially difficult to connect thermo-regulating physical variables to the subjective evaluation during transient conditions such as 'right after exercise' stage. It is necessary to measure the amount of heat and moisture transferred from the skin to the outside of clothing along with the physical properties measured in this study to understand the detailed mechanisms of why a cool sensation is evoked from tight fitting T-shirts made of newly developed cool touch fabrics.

Purpose: To report two cases of tsutsugamushi disease, showing ocular manifestations with eschars on the lower eyelids. Methods: Two patients who have tsutsugamushi disease with ocular manifestations were examined by standard ophthalmic procedures. Eschars were observed in both patients on the medial canthal lower lid. Conjunctival injection and episcleral vessel dilations were also observed in both patients. One patient had limbal vasculitis with pannus. Results: It is possible that eschars, which are the pathognomonic sign in tsutsugamushi disease, can occur on the eyelid, as well as on the axilla, perineum, abdomen, and extremities, which have been commonly observed sites. Ocular manifestations, including conjunctival injection, episcleral vessel dilation, or limbitis may be observed. These conditions may respond well to treatment with 0.1% Fluorometholone.
