It is presumed that the concept of time in traditional China contrast with that of western classics such as Aristotle, and Newton. Whereas the concept of the latter could be supposed as linear and physical, the concept of time in ancient China could be non-linear and natural. In this sense, the concept of time in traditional China is inherent. And this concept of time has peculiarity too, because it is casually fused with the dimension of space. Especially, its influence is significant in the various areas of Chinese traditional culture and thought in terms of its reflection on their motives and context, for example, in Nan k"o tai shou tien(南柯太守傳), the anecdote of Chao yen(趙顔), the anecdote of Hsu Yen(許彦), Double screens(重屛) of Sung-ming period, hand scroll(畵卷) and pavilion(庭園) culture of Sung-ming period. So it is not necessary to say that it has important meaning in the Chinese art and thought anymore.

<P><B>Abstract</B></P> <P>Response surface methodology (RSM) was applied to predict the processing parameters of the casein–glucose/galactose Maillard reaction (MR) for determining the level of <I>N</I> <SUP>ε</SUP>-(1-carboxymethyl)-<SMALL>L</SMALL>-lysine (CML), one of the typically harmful dietary advanced glycation end products (AGEs). The effect of industrial heating time and temperature of the MR on casein-glucose reactant (CGR) and casein-galactose reactant (CGaR) was evaluated. An increase in temperature and time was associated with an increased level of CML. A heating time of 114.8/117.9min and a temperature of 145.1/148.8°C maximised the formation of CML on CGR/CGaR and resulted in a CML production of 12.0/14.0μg/mL. Evaluation of foam stability, SDS-PAGE, and energy filtering-TEM indicated that the CGR and CGaR had different characteristics. Moreover, level of intracellular reactive oxygen species was accumulated with increasing CML contents. In summary, RSM provided a basis for understanding CGR/CGaR-reactivity and for predicting the formation of CML in heat-treated milk products.</P> <P><B>Highlights</B></P> <P> <UL> <LI> RSM was applied to predict the CML production in casein-monosaccharides model. </LI> <LI> The optimization of operating conditions was carried out to evaluate the properties. </LI> <LI> Level of intracellular ROS was accumulated with increasing CML contents. </LI> </UL> </P>

Purpose: To compare the preterm birth (PTB) by length of first birth interval (LFBI) in singleton birth among primiparous women. Methods: Data from the 2010-2013 birth certification of Korea Statistics (718,103 singleton first births) was used. Extra-marital birth, teenage birth, non-hospital birth cases, pre-marital pregnancy (shotgun birth) cases, and missing information (year and month of marriage, gestational age) were excluded from the data. Odds ratio and 95% confidence intervals were calculated from multinomial logistic regression analyses to describe the associations between the LFBI and the risk of PTB. Results: The mean LFBI from marriage to first birth was 24.4 months. The frequency of LFBI was 29.7 percent in LFBI of 8-12 months, 38.1 percent in 13-24 months, 22.7 percent in 25-48 months, 3.8 percent in 49-60 months, and 5.7 percent in ≥61 months. The rate of PTB was increased with prolonged LFBI. The incidence of PTB by LFBI was 3.9 percent in the LFBI of 8-24 months, 4.3 percent in 25-48 months, and 5.8 percent in ≥49 months. The odds ratio of PTB for the LFBI of ≥49 months was 1.327 (95% confidence interval: 1.299-1.427), compared with the LFBI of 8-24 months. The odds ratio of PTB was 1.695 (1.598-1.798) in women aged 35 and older with the LFBI of ≥49 months, as compared to women aged under 34 years with the LFBI of ≥8-24 months. Conclusion: A prolonged LFBI was associated with the increased preterm birth risk.

본 연구의 목적은 서비스실패가 발행한 이후에 이의 복구와 관련된 다양한 노력이 재구매 및 구전의도로 측정되는 고객충성도에 어떠한 영향을 미치는가를 확인하는 것이다. 본 연구에서 제시된 모형을 검정하기 위해 대전 및 충남지역에 거주하며, 이동통신, 패밀리레스토랑, 은행에서 서비스실패를 경험해 본 적이 있는 2-30대의 사람을 설문조사하였다. 수집된 데이터는 PLS 및 SPSS에 의해 통계분석 되었다. 통계분석을 통하여 본 연구는 서비스회복에 직접적으로 영향을 미치는 몇 개의 요소를 찾아냈으며, 서비스회복이 재구매 의도 및 구전에 미치는 영향을 확인하였다. 그 결과 본 연구에서 제시한 4가지 요인(즉각적인 보상, 신뢰, 반응, 확신)이 서비스회복을 중요한 선행요인으로 확인되었다. 부가적으로 세 개의 산업간 서비스회복모형을 비교해 본 결과 각각의 산업별로 중요시 여겨지는 요인들이 서로 다름을 확인할 수 있었다. 이러한 결과가 나온 이유는 각 산업의 특성에 따라 서비스회복을 결정짓는 요소는 다르기 때문이다. 따라서 각 산업의 서비스관리자들은 서비스실패를 회복하는 프로세스를 설계할 때 각 산업의 특성을 고려해야 한다. The purpose of this study is to uncover the influences of various efforts on service recovery after the failure of the service in regards to customer satisfaction and loyalty. The model was tested with a survey of 20–40 ages people who experienced service failure and service recovery in Daejeon and Chungnam. The collected data were analyzed statistics programs PLS and SPSS. As a result, the present study finds factors directly affecting service recovery and demonstrates the relationship of those factors between service recovery and customer loyalty. Furthermore, it discusses immediate compensation, truthfulness, reaction and assurance as the important factors for service recovery. In addition, factors that affect service recovery were compared among three services - telecommunication, family restaurants, and retail banks. It was found that the influence of immediate compensation, truthfulness, reaction, and assurance is different for each service type. This study result shows that a different service recovery is required, depending on the service characteristics.The purpose of this study is to uncover the influences of various efforts on service recovery after the failure of the service in regards to customer satisfaction and loyalty.

<P>Nitric oxide (NO) regulates proliferation, differentiation and survival of neurons. Although NO is reported to involve in NGF-induced differentiation of PC12 cells, the role of NO has not been characterized in primary neuron cells. Therefore, we investigated the role of NO in neuronal differentiation of primary cortical neuron cells. Primary cortical neuron cells were prepared from rat embryos of embryonic day 18 and treated with NMMA (NOS inhibitor) or PTIO (NO scavenger). Neurite outgrowth of neuron cells was counted and the mRNA levels of p21, p27, c-jun and c-myc were measured by RT-PCR. Neurite outgrowth of primary cortical neuron cells was inhibited a little by NOS inhibitor and completely by NO scavenger. The mRNA levels of p21 and p27, differentiation-induced growth arrest genes were increased during differentiation, but they were decreased by NOS inhibitor or NO scavenger. On the other hand, the level of c-jun mRNA was not changed and the level of c-myc mRNA was increased during differentiation differently from previously reported. The levels of these mRNA were reversed in NOS inhibitor- or NO scavenger-treated cells. The level of nNOS protein was not changed but NOS activity was inhibited largely by NOS inhibitor or NO scavenger. These results suggest that NO is an essential mediator for neuronal differentiation of primary cortical neuron cells.</P>
