Liquid chromatography/mass spectrometry using isotope dilution method has been established as a primary method for the measurement of cortisol in human serum. Verification of this method was accomplished by the participation in Consultative Committee for Amount of Substance-Metrology in Chemistry (CCQM) pilot study. Two levels of cortisol certified reference materials were prepared and certified by the established method. They were used as sample materials for the proficiency testing. The expanded uncertainty in the measurement of cortisol in human serum was approximately 1.2% at 95% confidence level. The results of the proficiency testing showed a good precision among the participants, but some bias to the certified values. This means that commercial field laboratories should keep traceability chain to SI unit through available reference measurement procedures and/or available reference materials.

It is really hard for the material factors to basically improve quality of life, since it is the only partial means of the survival and activity of life. Development of Eigen Shin-Tou-Jil(Proper Body·Earth materials), therefore, must be concentrated on providing man with essential meaning of life, not with simply economic advantage. Eigen Shin-Tou-Jil(Proper Body·Earth materials) which is formed through long passage of time in the original environments that include the climate and nature features of a special region, the representative examples are like Korea Bong-sam(a kind of genseng) of Yellow Earth etc. Unfolding the Eigen Shin-Tou-Jil(Proper Body·Earth materials) by the Algorithm of Human-ware means the development for manifesting individual eigen motives and traits as subject of behavior(Gene-ware). It is because all plants, animals, inanimate objects, including Human, have evolved with their own values in the ecosystem. It was reported that a Baeksong(white pine tree), grown well up in TongEeDong, Seoul, Korea had rarely grown up during the period suppressed by Japan. By the developments of Bio-Engineering, we also found that 40% of gene base sequence of C. Elegance(a kind of worm) is identical to that of characteristic Human. In this reason, through considering common characteristics between Human and Nature, the developments of Eigen Shin-Tou-Jil(Proper Body·Earth materials) must begin with epoch for manifesting and understanding individual's Eigen motives and traits as subject of behavior(Gene-ware)

The aim of the present study was to determine the influence of age of animal, hot carcass weight, pH, conformation and fat class on basic beef quality attributes (tenderness, sarcomere length, basic chemical composition, marbling and colour) in a group of purebred animals. The object of the study was beef of Limousin bulls (25 to 27 months, hot carcass weight - $432{\pm}31$ kg, "U" conformation class, "2"-"3" fat class). Analysed cuts were Infraspinatus muscle from the blade and Longissimus dorsi muscle from the cube roll and the striploin. Tenderness was analysed with universal testing machine, colour - chromometer analysis, sarcomere length - microscopic method, basic chemical composition - near-infrared spectroscopy and marbling - computer image analysis. No differences in tenderness and sarcomere length were observed within the age groups of Limousin bulls (age of 25, 26, 27 months) (p>0.05). Moisture (p = 0.0123) and fat (p = 0.0250) content were significantly different for meat of animals slaughtered at the age of 25 and 27 months. No influence of pH value on tenderness was observed, but at the same time, influence on sarcomere length (p = 0.039) and $b^*$ component of colour (0.045) was found. For "U" conformation class, in subclasses, as well as for fat classes "2"-"3", there were no differences in tenderness, sarcomere length and colour components. Higher fat content was observed in the higher fat class, rather than in lower, however this feature was not associated with marbling.

The purpose of this study was to investigate the effect of personality traits of the middle aged on quality of life while mediated by self-concepts such as self-efficacy and self-derogation, as well as while moderated by subjective socio-economic variables such as economic status, social activities and employment. To verify the conceptual causality model and moderating effects of contextual variables, we analysed 353 cases out of purposively collected 400 cases from a medium sized city. As results, first, conscientiousness of personality traits positively affected quality of life of the middle aged while mediated by self-concepts. Second, neuroticism of personality traits negatively affected quality of life while mediated by self-concepts. Third, agreeableness of personality traits did not eventually affect quality of life, although affected negatively on self-efficacy and positively on self-derogation. Fourth, socio-economic variables such as economic status, social activities and employment moderated various paths in the model, which indicated dynamics of internal variables were affected by contextual variables.

The purpose of this study is to examine the mediation effects of relationships of parent-child and between-peers based on the effects of economic difficulty on quality of life of elementary school students. Data was obtained from students (N= 493) at seven elementary schools in Choongbuk Province and analyzed with SPSS 12.0 and Structural Equation Modeling with AMOS 5.0. The major findings are as follows: economic difficulty gives a direct effect on elementary students' quality of life and is mediated with parent-child and between-peers relationships. Also, economic difficulty influences children's quality of life when a parent-child relationship is combined with a between-peers relationship. On the basis of these results, this study suggests that welfare centers and elementary schools have to teach students to have desirable sense of value. Also, schools need to provide education programs for parents to improve parent-child relationship and various activities for students to develop between-peers relationship.

Interest in aspects of industrialization relating to human health has increased. Accordingly, the use of labels such as 'natural foods' and 'organic ingredients' has become more widespread, and greater emphasis is being placed on improving quality of life. Water is an essential element for human life, and water quality has a significant impact on human health. However, technology that can precisely determine the substances present in water is still lacking. This study was conducted to establish a complete mass spectrometry process, from pretreatment to analysis, to measure and characterize natural organic matter (NOM) in Korean spring water samples. Salts and other matrices were removed from the samples using solid-phase extraction (SPE) with two different columns (PPL and C18). After establishing an accurate analysis method, the experimental results were evaluated based on Van Krevelen diagrams and analysis of molar O/C and H/C ratios. The method for characterizing NOM introduced herein should facilitate evaluation of water quality.

이 글은 근대에 의한 현대 체제 일반과 그를 극복하려는 탈근대 담론 안에서 왜 로컬 혹은 로컬리티가 필연적으로 인간 삶의 존재론적 '사이'의 문제로 제기될 수밖에 없는지를 철학적으로 조명하려는 시도를 담고 있다. 따라서 우리는 근대와 탈근대의 논의 과정에서 제기된 수많은 문제들 중 인간존재에 대한 근본적인 물음을 제기하면서 동시에 인간 삶의 질을 점검할 필요가 있다(2). 또한 이 과정에서 로컬 혹은 로컬리티는 인간 삶의 질과 어떤 연관성을 맺고 있는지도 자세히 들여다보아야 할 것이다. 왜냐하면 로컬 안에서만 비로소 인간은 다양한 질감의 흔적과 주름들이 뒤엉켜 시간과 장소를 의미화시켜 나가는 주체가 되기 때문이다. 여기서 주체들은 상호주관적 관계망을 통해 사회를 이루고 함께 살아간다는 것을 확인할 수 있다(3). 이럴 때 로컬 혹은 로컬리티는 참된 인간적 사회적 삶이 가능한 장소, 즉 존재론적 '사이'로서 로컬리티 인문학의 가능성으로 드러나게 될 것이다(4).

Background: Previous research has suggested that single doses of a standardised Panax ginseng extract can decrease fasted blood-glucose levels and modulate cognitive performance in healthy young volunteers. The latter has generally been seen in terms of improved secondary memory performance. However, both the cognitive effects of chronic administration of ginseng and the potential modulation of working memory have received comparatively little research attention. Aims: The current double-blind, placebo-controlled, balanced cross-over study investigated the effects of 8-weeks administration of Korean ginseng extract (200 mg) on cognitive performance, gluco-regulatory parameters and ratings of subjective mood and 'quality of life'. Methods: 'Eighteen healthy young participants were assessed pre-dose and 3 hours post-dose on the mornings of Day 1, Day 29 and Day 57 of 8 week treatment regimens of both placebo and ginseng. A four-week placebo wash-out separated the treatment phases. Each assessment included the Cognitive Drug Research battery, computerised working memory tasks, and Bond-Lader mood scales. The WHO Quality of Life scale (WHOQOL-BREF) was completed once per visit. Gluco-regulatory parameters were assessed with assays of blood glucose, insulin and HbA1c. Results: Data from the 16 participants that completed the study showed that there were no significant, acute treatment related differences on Day 1 of treatment, or in gluco-regulatory parameters throughout the study. However, time related performance improvements were evident following chronic administration of ginseng on the '3-Back' and 'Corsi-block' computerised working memory tasks. Ginseng was also associated with an improved score on the 'social relations' subscale of the WHOQOL-100, and a significant shift on the 'calm' factor of the Bond-Lader mood scales (from calm/relaxed towards excited/tense). Conclusion: The results of the current study suggest that Korean ginseng extract can modulate working memory performance and subjective ratings of 'quality of life' and mood. Replication with a larger sample size may further elucidate the actions of this product.
