Phenol compounds in water were simultaneously analyzed by extractive derivatization. Aqueous solution was controlled to pH 13 with sodium hydroxide, and then $500{\mu}L$ of benzoyl chloride was added to the solution. The solution was shaken for 15 minutes and extracted with diethyl ether and then analyzed using GC/MS-SIM. The calibration curves of phenolic compounds in the range of 0.05 to $5.0{\mu}g/mL$ showed a good linearity having the correlation coefficient of $r^2=0.9915$ and standard deviation of ${\leq}8.5%$, respectively. The recoveries by this method ware 58.4-114.0%.

The purpose of this paper is to analyse the mother-daughter structure presented in Annie John, Kincaid's autobiographical novel as a metaphor for the relationship between the powerful colonizer and the powerless colonized. The representation of the mother in Annie John is ambiguous and ambivalent. On the one hand, the mother in the childhood, in its association with the African-rooted Caribbean world before Antigua was colonized, is represented as a person who nurtures the daughter, and embodies a paradisiacal pre-oedipal union with the daughter. On the other hand, the mother at the adolescent stage, placed in the specific colonial context of the Caribbean, is represented as a scornful person/colonizer who dominates and controls the daughter's behavior to keep her as a dependent and subjugated subject. Therefore, the two conflicting worlds, the African and the European, coexist in the contradictory figure of the mother. The theoretical basis of my argument is a mixture of Chodorow's and Kristeva's feministic psychoanalysis and Bhabha's notion of "mimicry" and "ambivalence." Kristeva's work on "abjection" is especially useful and helpful for contextualizing Annie's individuation and separation from the mother who is represented as enigmatic.

Based on goal-achievement and embodied cognition theories, this research investigates how goal-achievement status, which is specified into goal under-achievement, achievement, and over-achievement, influences one's preference for the degree of hardness (vs. softness) in products. The results reveal that consumers who have not yet reached or who just met their goals compared to those who over-achieved their goals want their products (e.g., pillows, mattresses, chairs) to be firm rather than soft. Existing embodied cognition studies have mostly focused on how physical experiences affect consumers' judgments and product preferences, whereas this research shows that consumers can automatically pursue physical experiences according to their goal achievement status.

A construction project of Incheon 2nd bridge, which is connected between the Incheon Song-Do New Town and the Incheon International Airport in Young-Jong-Do, have been proposed by the private capital in 1999. But the optimal span width in the bridge main span have not been decided in spite of the three investigations into the feasibility of ship's safe transit in this planned bridge. In this paper, we study the economic analysis on port operational efficiency according to traffic schemes, me-way or two-way of vessels over 10,000G/T, in the bridge main span of this bridge. In this comparative result, total queueing time due to the one-way in the bridge main span is evaluated 20,362 hours in 2011 and 24,544 hours in 2020. Therefore the demurrage cost and the accumulation cost of freight are evaluated 19.7 billion won in 2011, and 23.3 billion won in 2020, then total accumulated costs during 33 years from 2008 until 2040 are evaluated about 768..9 billion won.

Although previous studies have emphasized factors affecting people's variety-seeking behavior, research has not been performed to examine the interaction effect of good-bad luck and embodied cognition (hand washing) on variety-seeking behavior. Experience of good and bad luck affects consumer information processing and hand washing is known to reverse the experience of luck. Understanding the interaction effect of good/bad luck and hand washing on variety seeking behavior will shed important light on consumer behavior including choice and product purchase. To do this, a study was performed to investigate the effects of good/bad luck priming and hand washing on variety seeking behavior. Participants were primed with good or bad luck and then were asked to either wash their hands or not. After that, they were led to choose yogurt for the next seven days and the dependent measure was the number of different tastes of yogurt participants picked up. An interaction effect of luck priming and hand washing was found. Results indicate that, in good luck condition, there was no difference in variety seeking behavior between hand washing participants and non-hand washing participants. However, in bad luck condition, hand washing participants chose less diverse tastes of yogurt than non-hand washing participants. Implications of the study findings for the field of consumer psychology and marketing are discussed.

Methamphetamine is an amine-containing illegal drug and is distributed unlawfully in South Korea. Finding a rapid, convenient and semi-quantitative determination method for methamphetamine is a very important issue in the area of forensic drug testing. As an effort to develop new screening method, the reactions between three organic compounds which are structurally similar to methamphetamine and N-(9-fluorenylmethoxycarbonyloxy) succinimide (FMOC-NHS) were performed on silica gel ($SiO_2$) TLC plates. Three reference compounds were synthesized and used for the identification, comparison and study of the limit of detection (LOD) of the products obtained from a direct reaction on a TLC plate. As a result, FMOC-NHS as a derivatization reagent generated compounds containing highly UV-active functional groups on the TLC plate after reacting with primary- and secondary amines. In the experiment 2D the LOD of amines was in the range of 0.045 and 0.01 mg/mL ($2{\mu}L/spot$), and in 1D the LOD was in the range of 0.002 and 0.007 mg/mL ($2{\mu}L/spot$). The LODs of the compounds tested were dependent on the concentration of the derivatizing reagent.

In order to unravel the problems of the mind, today's cognitive science has expanded its perspective from the narrow framework of the past computer model or neuronal network model to the wider frameworks of interaction with the brain in interaction with the body in interaction with their environments. The theories of 'the extended mind', 'embodied mind', or 'enactive mind' appeared through such processes are working on a way to move into the environments while the problem to unravel the complex process of interactions between the mind, the body and the environments are left alone. This problem can be traced back as far as to Gibson and Maturana & Varela who tried at first to unravel the problem of the mind in terms of interaction between the brain, the body and there environments in 1960~70s. It's because Gibson stressed the importance of the 'affordance' provided by the environment while Maturana & Varela emphasized the 'autonomy' of auto-poiesis of life. However, it will be proper to say that there are invariants in the affordances provided by the environment as well as the autonomy of life in the state of structural coupling of the environment's variants and life's openness toward the environment. In this case, the confrontational points between Gibson and Maturana & Varela will be resolved. In this article, I propose Benjamin's theory of mimesis as a mediator of both theories. Because Benjamin's concept of mimesis has the process of making a constellation of the embodiment of the affordance and the enaction of new affordance into the environment at the same time, Gibson's concept of the affordance and Maturana & Varela's concept of embodiment and enaction will be so smoothly interconnected to circulate through the medium of Benjamin's concept of mimesis.

A sensitive derivatization method by using the TFE/TFAA as derivative reagent is proposed for the determination of acidic herbicides in water, by using this method, method detection limits are improved by 10 times and sample volumes are decreased by 5 times compared with other methods such as U.S. EPA and SPEED 98. And also, in order to suggest higher creditable standard operating procedure (SOP), intra- and inter-lab validation test carried out by four laboratories include our lab. The results of intra and inter-lab validations in same experimental conditions show good linearity in given range of concentrations as a $0.1{\sim}10.0$ ng/ml, and range of accuracies and precisions show $-20.5{\sim}12.2$ bias%, $0.55{\sim}24.48%$ (for intra-lab validation) and $-6.66{\sim}0.80 bias%$, $1.92{\sim}13.86%$ (for inter-lab validation), respectively.

A new technique was proposed for the determination of alkylphenols, chlorophenols and bisphenol A in korean aquatic biological samples. The alkylphenols, chlorophenols and bisphenol A in korean aquatic biological samples were extracted with acetonitrile and then acetonitrile layer was refrigerated at $-60^{\circ}C$ for 2 hours(freezing filtration method). Also, solid-phase extraction(SPE) was used to XAD-4 and subsequent conversion to isobutoxycarbonyl(isoBOC) or tert-butyldimethylsilyl(TBDMS) derivatives for sensitive analysis with gas chromatography/mass spectrometry-selected ion monitoring(GC/MS-SIM) mode. For isoBOC derivatization and TBDMS derivatization the recoveries were $70.1\sim150.6%$ and $93.8\sim108.3%$, the method detection limit(MDLs) of bisphenol A for SIM were $0.062{\mu}g/kg$ and $0.010{\mu}g/kg$, and the SIM respectively. When these methods were applied to korean aquatic biological samples, the concentrations of the 11 phenolic EDCs were $0.675\sim1.970{\mu}g/kg$.
