This paper aims at exploring the multi-scalar processes through which the Gumi Industrial Complex was developed in the late 1960s and the early 1970s. Existing studies, influenced by the "Developmental State Thesis", tend to see the industrialization processes of South Korea either by focusing on the socio-politico-economic processes at the national scale or in terms of the plan rationality of the national bureaucrats. This paper, however, denies this perspective on the basis of the strategic relational approach to the state and the multi-scalar perspective. In particular, it argues that the state actions for national industrialization have been the outcome of complex interactions, conflicts and negotiations among social forces, acting in and through the state, and at diverse geographical scales. This paper attempts to empirically prove this argument on the basis of a case study on the construction processes of Gumi Industrial Complex. The development of Gumi Industrial Complex cannot be solely explained in terms of either the plan rationality of the national bureaucrats or the political motivation related to the fact that Gumi was the hometown of President Park Jung-Hee. This paper argues that the development of Gumi Industrial Complex was heavily influenced by the role of the following actors; place-dependent local actors in Gumi and the multi-scalar agents, such as the Korean-Japanese businessmen and the national parliament members elected in the Gumi electoral district.

This study investigated and summarized the history of peasant movement which had been done by various peasant associations Yesan, Hongsong, and Tangjin from the beginning of Korean Catholic Peasant Movement from 1970 to 1995. First of all, we classified all the peasant movements(Yesan ; 120 times, Hongsong; 113 times and Tangjin; 107 times / total; 340 times) into 5 categories composed of movement time, movement type, movement method, the number of participators, and the movement subjects(issues). The frequency of peasant movement from 1990 to 1995, occupied 65.6%, which shows that the peasant movement was the most active during the time. The frequency of movement type, were we could find out, self-dependence type(62.9%), resistance type(15.6%) and request type(21.5%). The active way like congregation, demonstration, sit-in, rice file up struggle occupied 28.8% and it got the first place in movement way. In the movement subject category, the construction of organizations and solidarity activity amounted to 37.8% and democratization item(the union democratization and the social democratization related peasant) covered 16.8%. The 98 times of peasant movement were done in the active ways such as congregation and demonstration. However we cannot find these active ways in 1970s. In 1980s, the frequency of each item (congregation, demonstration, publicity and propaganda) was 28 times. But in 1990s, the frequency of congregation, or demonstration was higher than the others. The number of participators in peasant movement increased during 1980s∼1990s. The movement of which participators were 100∼499 was 32 times in 1980s and 70 times in 1990s each time. Such large scale movement amounted to over 30%. Furthermore, the large scale movement in which over 500 people participated amounted to 12 times in 1990s.

Korea's trading volume is expected to surpass USD 1 trillion in 2011. Korean economy achieves this largely due to its dependence on export and enhanced technological capacity and product quality. Improved recognition of Korean enterprises in the global arena also helped. However, the largest reason behind theses could be found in exporters' ceaseless marketing endeavors and continued government supports. Today, more and more people become to rely on trade exhibitions to boost export effectively. Trade exhibitions are employed as a useful tool to attract buyers and enter a market. This is because such exhibitions' marketing effect and professional aspects. South Korean export relies on large conglomerates for most part. However, 95% of the country's entire industry are small and medium-sized companies. This means that SMEs' export has a huge impact on the national economy. Therefore, as a way to improve SME export and minimize their losses, we need to use trade exhibitions more actively. The overseas policy insures only promotional activities regarding foreign exhibition and fair (including international events held in Korea), foreign distributor, shopping mall, home shopping, etc. and does not include air fare, traffic cost in the local place, accommodation cost and dining expenditures as costs to be excluded mentioned above. It is not easy for them to take part in events abroad if they have to pay for such expenses. If full financial support is difficult, the Korea trade insurance corporation still may give a certain level of aid for successful exporters to engage in marketing activities abroad more actively and further stimulate SMEs' export.

The apparent and partial molal volumes({\phi}\nu$and $V^{\circ}$) of a series of homologous n-alkylamine hydrochlorides $C_nH_{2n+1}NH_3^+Cl^-$, where n varies from zero to four, have been determined by means of a float method at 30$^{\circ}C$ to the fifth decimal place down to 0.01M in aqueous solutions. The experimental results indicate that the partial molal volumes of the salts are almost additive for successive homologues depending on the increment of molecular weight ($CH_2$). It has been observed that the concentration dependence of the ${\Phi}v$ are linear in general and limiting slopes are positive and relatively close to the theoretical values. Anionic partial molal volume of chlorides anion $V^{\circ}_{Cl^-}$ is found to be 18.6 ml $mole^{-1}$, which is in good agreement with the results of other workers. {\phi}\nu$ data also show that in solution the hydrophobic effect of ions are in competition with the charge effect, but the latter, that is, electrostriction seemed to be considerably predominant.

Infanthood is a crucial period when mental and emotional developments take place along with physical growth. Adequate supply of nutrition is essential during this period and there is an urgent need for proper education and guidance on balanced nutrition. Therefore, this study was designed to assess to current status of lactation and to investigate mothers' perspectives on human milk and formular milk. As random samples for this study, a total of 352 mothers having infant under the age of 4 were surveyed. 27.3% of mother surveyed were breast-feeding, 38.0% were formula-feeding and 34.7% were mixed-feeding. According to the result of this study, the percentage of breast feeding was on the decrease, while the dependence on formular milk was on the rise. The main reason of formula-feeding was insufficient secretion of human milk on mothers part. The major factors that affect to select feeding method were employment status, degree of education, family income and age. Also, the interviewees desired the product fortified with special ingredients that are hot contained in formular milk currently available in the market. The most concerned problem of formula milk was indigestion and the interviewees wanted the formular milk to be improved digestibility.

Research was taken its place in Dong wun elementary school in Gwang ju city. Subject ages were somewhere around 9 to 13. Among total number of 1,196, subjects with emmetropia were 384 people (32.1%), with 22.56% of 9 year old students, 16.01% of 10 year old student, 36.45% of 12 year old student, 39.11% of 13 year old. When age increases, the rate of emmetropia increase as well. Gender dependence of emmetropia rato was 31.07% for boys and 33.33% for girls, which proves girls with higher emmetropia ratio than boys. Among subjects with binocular vision acuity lower than 0.7, those require spectacles, only 37.5% of 9 years old students, 30.3% of 10 year old students, 44.64% of 12 year old students, and 30% of 9 year old students were wearing glasses. It shows that spectacle-wearing ratio is very low in spite of visual acuty lower than 0.7.

To prepare $Mn^{4+}$-activated $K_2TiF_6$ phosphor, a precipitation method without using hydrofluoric acid (HF) was designed. In the synthetic reaction, to prevent the decomposition of $K_2MnF_6$, which is used as a source of $Mn^{4+}$ activator, $NH_5F_2$ solution was adopted in place of the HF solution. Single phase $K_2TiF_6$:$Mn^{4+}$ phosphors were successfully synthesized through the designed reaction at room temperature. To acquire high luminance of the phosphor, the reaction conditions such as the type and concentration of the reactants were optimized. Also, the optimum content of $Mn^{4+}$ activator was evaluator based on the emission intensity. Photoluminescence properties such as excitation and emission spectrum, decay curve, and temperature dependence of PL intensity were investigated. In order to examine the applicability of this material to a white LED, the electroluminescence property of a pc-WLED fabricated by combining the $K_2TiF_6$:$Mn^{4+}$ phosphor with a 450 nm blue-LED chip was measured.

The reaction of methyl radical with iodine molecule on an attractive potential energy surface is studied by classical trajectory procedures. The reaction occurs over a wide range of impact parameters with the majority of reactive events occurring in the backward rebound region on a subpicosecond scale. A small fraction of reactive events take place in the forward hemisphere on a longer time scale. The ensemble average of reaction times is 0.36 ps. The occurrence of reactive events is strongly favored when the incident radical and the target molecule align in the neighborhood of collinear geometry. Since the rotational velocity of I2 is slow, the preferential occurrence of reactive events at the collinear configuration of $CH_3{\ldots}I{\ldots}$I leads to the reaction exhibiting an anisotropic dependence on the orientation of $I_2$. During the collision, there is a rapid flow of energy from the $H_3C{\ldots}$I interaction to the I-I bond. The $CH_3I$ translation and $H_3C$-I vibration share nearly all the energy released in the reaction, and the distribution of the vibrational energy is statistical. The reaction probability is $\cong$0.4 at the $CH_3$ and I2 temperatures maintained at 1000 K and 300 K, respectively. The probability is weakly dependent on the $CH_3\;and\;I_2$ temperatures between 300 K and 1500 K.

Panax ginseng has been useful for the treatment of diverse disease in oriental countries for thousands of years. In addition, a folk medicine prescribed by seven herbal drugs including Panax ginseng has been antinarcotics in the treatment of morphine-dependent patients. Many articles have been reported on these works. Therefore, we review the protective effects of Panax ginseng on the neurotoxicity induced by abuse drugs. Ginseng total saponins (GTS) extracted and isolated by Panax ginseng antagonized Morphine-induced analgesia, and inhibited the development of analgesic tolerance to and physical dependence on morphine. GTS inhibited morphine-6 dehydrogenase, which catalyzes production of mophinone from morphine, and increased hepatic glutathione level responsible to toxicity. Therefore, we hypothesized that these dual actions of ginseng can be associated with the detoxication of morphine. In addition, the inhibitory or facilitated effects of GTS on electrically evoked contraction in guinea pig ileum ($\mu$-receptors) and mouse vas deferens($\delta$-receptors) were not mediated through opioid receptors, suggesting non-opioid mechanisms. On the hand, antagonism of U-50,488H ($\kappa$-agonist)-induced antinociception is mediated by serotonergic mechanisms. GTS also inhibited hyperactivity, reverse tolerance (sensitization) and conditioned place preference-induced by psychostimulants such as methamphetamine, cocaine and morphine. On the other hand, GTS reduced the dopamine levels induced by methamphetamine. Moreover, GTS blocked the development of dopamine receptor activation, showing antidopaminergic effect. We suggest that GTS Prevent the methamphetamine-induced striatal dopaminergic neurotoxicity. In addition, Ginsenoside also attenuates morphine-induced cAMP signaling pathway. These results suggested that GTS might be useful for the therapy of the adverse actions of drugs with abuse liability.
