  • In recent years, the home meal replacement (HMR) market has expanded and the consumption of ready-to-heat (RTH) rice has significantly increased. In this study, RTH rice products containing seaweed were prepared with different types of grain: white rice, a mixture of white rice and barley, barley, and mixed grains. The control was a commercial RTH white rice without seaweed. The proximate components, total dietary fiber, in vitro starch digestibility, and antioxidant activity were compared. The ash content of the RTH seaweed rice was higher than that of the control (P<0.05). The total dietary fiber of the RTH seaweed rice was in the range of 1.03-6.57%, which directly impacted the in vitro starch digestibility. The in vitro antioxidant activity including total phenolic content, reducing power, DPPH (2,2-diphenyl-1-picryl-hydrazyl) and ABTS+ (2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid) radical scavenging activity of the seaweed rice with barley and the white rice/barley mixture was greater than that of the other rice products (P<0.05). These results indicate that the in vitro digestibility and antioxidant activity of the HMR RTH seaweed rice were greater than those of the control. In addition, when the RTH seaweed rice was prepared with barley, the functional activity improved.

  • Energy-based seismic design of structures has gradually become prominent in today's structural engineering investigations because of being more rational and reliable when it is compared to traditional force-based and displacement-based methods. Energy-based approaches have widely taken place in many previous studies and investigations and undoubtedly, they are going to play more important role in future seismic design codes, too. This paper aims to compute the maximum earthquake energy input to elastic single-degree-of-freedom (SDOF) systems for selected real ground motion records. A data set containing 100 real ground motion records which have the same site soil profiles has been selected from Pacific Earthquake Research (PEER) database. Response time history (RTH) analyses have been conducted for elastic SDOF systems having a constant damping ratio and natural periods of 0.1 s to 3.0 s. Totally 3000 RTH analyses have been performed and the maximum mass normalized earthquake input energy values for all records have been computed. Previous researchers' approaches have been compared to the results of RTH analyses and an approach which considers the pseudo-spectral velocity with Arias Intensity has been proposed. Graphs of the maximum earthquake input energy versus the maximum pseudo-spectral velocity have been obtained. The results show that there is a good agreement between the maximum input energy demands of RTH analysis and the other approaches and the maximum earthquake input energy is a relatively stable response parameter to be used for further seismic design and evaluations.

  • 갑상선 호르몬 저항성 증후군은 갑상선 호르몬에 대한 조직의 반응이 감소되어 나타나는 드문 유전 질환이다. 대부분은 갑상선 호르몬 수용체 (TR) 유전자의 돌연변이로 인한 갑상선 호르몬 수용체의 결함에 의한다. TR 유전자의 변이는 일반적으로 이형접합성이며 상염색체 우성 유전 양상을 보인다. 혈청 갑상선 호르몬 수치가 증가되어 있음에도 불구하고 혈청 갑상선 자극호르몬 수치가 억제되지 않으며, 임상 양상은 다양하다. 본 증례는 경미한 갑상선종, 총 및 유리 $T_4$, $T_3$의 증가, 정상 범위의 TSH 소견을 보이는 4세 여아로서 TR 유전자 분석에서 과오돌연변이(H435Y)를 확인하였다. 부모에서는 돌연변이가 관찰되지 않았으며, 갑상선 기능도 정상이었다. 특별한 투약 없이 추적 관찰 중에 갑상선종의 증가나 다른 증상의 악화는 없는 상태이다.

  • The effect of the out-of-plane retardation (Rth) of a substrate film on the viewing-angle dependence of transmittance (TR) in a display device was investigated. When the polarization state of input light deviates from the transmission axis of the polarizer, Rth of the substrate film induces inhomogeneous viewing-angle dependence of TR. The inhomogeneity of TR gets worse for greater values of of Rth. The inhomogeneous TR profile can be eliminated by inserting compensation films, which convert the input polarization state to the linear polarization state parallel to the transmission axis of the polarizer.

  • Resistance to thyroid hormone syndrome (RTH) is a genetic disease caused by the mutation of either the thyroid hormone receptor-β (THRB) gene or the thyroid hormone receptor-α (THRA) gene. RTH caused by THRB mutations (RTH-β) is characterized by the target tissue's response to thyroid hormone, high levels of triiodothyronine and/or thyroxine, and inappropriate secretion of thyroid-stimulating hormone (TSH). THRA mutation is characterized by hypothyroidism that affects gastrointestinal, neurological, skeletal, and myocardial functions. Most patients do not require treatment, and some patients may benefit from medication therapy. These syndromes are characterized by decreased tissue sensitivity to thyroid hormones, generating various clinical manifestations. Thus, clinical changes of resistance to thyroid hormones must be recognized and differentiated, and an approach to the practice of personalized medicine through an interdisciplinary approach is needed.

  • When we have an i.i.d. sample of size n from a continuous distribution, the distribution truncated on the left at the rth order statistic plays an important role in the theoretical analysis of the Type 2 censored data. The charaterization of distributions by the average of the conditional expectation and the average of the conditional information concerning the truncated distribution is studied here.

  • In South Korea, social, the number of single-person households has rapidly increased because of financial factors. Since single-person households have characteristics differentiated from general households, many enterprises pay attention to them that appear as important consumers. This study conducted a survey with consumers in their 20s to 50s in single-person households, nationwide who had an experience of purchasing HMR. The results of this study can be summarized as follows: First, of the benefits pursued in dietary life, the pursuit of nutrition a negative (-) impact on RTH type and did not have any impacts on the RTE and RTC types. The pursuit of taste had a positive (+) impact only on the RTE type while it did not have any impact on the RTH and RTC types. The pursuit of convenience had positive (+) impacts on all RTH, RTE and RTC types, while the pursuit of price sought did not have any impact on all types. Second, of the preferences by each HMR type, preferences for the RTH and RTC types had positive (+) impacts on purchase intention while preference for the RTE type did not have any impact on purchase intention. Third, of the benefits pursued in dietary life, the pursuits of taste and convenience had positive (+) impacts on purchase intention while the pursuits of nutrition and price did not have any significant impacts on purchase intention. In addition, of the benefits pursued in dietary life, the pursuit of convenience had a significant impact on purchase intention mediated by preference by each HMR type. As a result, taste of HMR and the aspects of convenience act as factors inducing purchases, and products in the various forms of taste and convenience in order to appeal consumers who pursue taste and convenience.

  • In mammalian, cytochrome P4501A1 (CYP1A1) is very important for metabolism of xenobiotics such as PAHs(Polycyclic aromatic hydrocarbon) and heterocyclic amine, and it is induced by environmental contaminants such as PAHs, TCDD(2,3,7,8-tetrchlorodibenzo-p-dioxin) and 3-MC (3-methylcholanthrene). In fish, like mammalian, when it is exposed to environmental contaminants, they cause specific and sensitive induction of CYP1A. Therefore, induction of CYP1A in fish and mammalian is widely used as a biomarker for exposure of environmental contaminants. In this study, to compare the function of Cyp1a1 in fish with it in mammalian, we have used rainbow trout(Oncorhynchys mykiss) hepatoma cells (RTH-149) and mouse hepatocyte (Hepa-I). in order to examine induction of Cyp1a1 by TCDD, we have used the bioassay system. We examined effects of TCDD on the Cyp1a1-luciferase reporter gene activity, 7-ethoxyresorufin O-deethylase(EROD) activity and Cypa mRNA level.
