The objective of this study was to verify the longitudinal reciprocal causal relationship between depression and the somatic symptoms of depression among adolescents through an autoregressive cross-lagged model using data from the Korean Children & Youth Panel Survey. The subjects of this study included 1,968 adolescents, who participated in the second, fourth, and sixth Korean Children & Youth Panel Surveys. The results showed that both depression and the somatic symptoms of depression at a previous point in time affect depression and the somatic symptoms of depression at a later point in time. It was also found that depression at a previous point in time has a cross-lagged effect on the somatic symptoms of depression at a later point in time, implying that more severe depression at a previous point in time leads to increased severity of somatic symptoms at a later point in time. It was found that the somatic symptoms of depression at a previous point in time have a cross-lagged effect on depression at a later point in time, indicating that more severe somatic symptoms of depression at a previous point in time lead to increased severity of depression at a later point in time. This study is significant in that it provides baseline information about nursing interventions for adolescent mental health.

With the Japanese attacks on Pearl Harbor in 1941, approximately 2,500 people were killed. The terrorist attack on World Trade Center in the United States resulted in the heavy loss of people's lives, 2,749 in all. The 9.11 demonstrated that terrorist attack could be more serious problem than the war in our modern life. In addition, terrorist armed with new and high technologies have become more dangerous elements to the international community. Especially, the fact that the weapons of mass destruction are used by terrorist organizations is a matter of great concern. The strength of terrorist arsenal gives terrorist a decided advantage over us. The chances of success for terrorist have been increased due to the terrorist friendly environments. Terrorism has evolved without stopping from its birth, which is imposing a great burden on the authorities concerned. The counter-terrorism strategy and tactics used in the past have been useless in the fighting against new terrorism. To cope with the fast changing terrorism, comprehensive countermeasures should be developed. The purpose of this study is to know the enemy. To achieve the goal, the current situation on international terrorism as a whole is examined. Based on the result of the research, this paper also tried to give a perspectives on the future terrorism. At the same time, it provides a guidelines of the direction in the fighting against terrorism.

is a 1968 western novel by Charles Portis. The novel was adapted for screenplay of the 1969 movie of the same name directed by Henry Hathaway. In 2010, Coen brothers directs, writes, and produces the second adaptation of Portis's novel writing most of the script. Of nineteen films directed by Coen brothers, only and are adapted from novel. (released as in Korea), is the only remake of an existing film by Coen brothers. The story plot of the novel or the 1969 or 2010 do not differ greatly, however by emphasizing on different subjects, the character development is slightly altered and in the end, all three are perceived as unique. By comparing what each story is trying to emphasis, examining different cinematic devices, and how it relates to previous worldviews of modern America seen through Coen brothers, portrays a dark society continuously consuming and while illustrating origin of problematic American society.

The Face Stimulus Assessment is an efficient projective drawing test developed by Betts. This paper categorizes scales which Betts suggested into the following five groups: accuracy of painting, color fit, perception of shape, precision of drawing, and space usage. In this paper, a computer algorithm which objectively evaluates these five scales is suggested. The proposed algorithm defines the areas of the lip, eyes, hair, etc. which take on significant roles in the evaluation of the FSA and based on these factors, it calculates the grade of each scale through the main color and color ratio. The consistency of evaluations between the computer algorithm and the art therapist is measured by the Quadratic Weighted Kappa. By providing objectivity and consistency, the computer algorithm is expected to solve the problem of uncertainty found in art therapists' evaluations of projective drawing tests caused by their subjective judgment, experience, and intuition.

During the period from 1966 to 1968, total catches of Spanish mackerel averaged 6,000 to 7,000M/T per annual in Korea, and approximately 70 per cent of this amount was captured by drift nets. In an effort to improve the efficiency of drift nets, some experiments were conducted in 1969 to investigate the selectivity of material and mesh sizes. Seven different mesh sizes (80,85,95,100,105,110 and 115 mm) of both multi- and mono-filament netting were used, and the following results were obtained : 1, The body weight of Spanish mackerel taken with the seven different mesh sizes ranges from 0.5kg to 2.9kg, and the mode of body weight consists of three groups, 1kg ($21%$), 1.3kg($15\%$) and 1.5kg($19\%$). 2. For multi-filament net, 80 to 105mm mesh sizes were suitable to catch those three groups, and a little smalter than these for mono-filament net. 3. For Spanish mackerel only, the mono-filament material proved to have 1.5 times better selectivity than multi-filament : however, the latter proved superior for miscellaneous fish species due to its different size and shape. 4. Multi-filament net showed better selectivity for smaller species than mono-filament. (and mono-filament in general indicated opposite phenomenon.)

Bathythermograph (B. T) has been coumonly used to obtain a records of water temperature in the depth of 270m from the surface. We have, however, experienced some difficulties in obtaining smoked or coated glass which is used for the bathythermograph in this region, Therefore I introduce a easy method of preparing the smoked-glass slide. Preparing method is as follows. 1. Glass slides must be cleaned by dipping into the concentrated solution of sodium hydroxide ana hydrochloric acid then rinsing with hot water and polishing with a clean gauge. 2. The cleaned slide is immersed in the wax solution for coating, and dried on the filter paper. The Wax solution is prepared as follow : 1g of white wax is dissolved in 200CC of benzol or 1g of lard is dissolved in 300CC of gasoline. 3. A slide held in a fingertip is smoked on the flame of alcohol lamp, or Meter burner. When alcohol lamp is used the fuel alcohol must contain 1/5 of benzol, and when Meker burner is used, the air intake must be blocked up. The smoking on the glass slide should be light and uniform, after smoking the slide is cooled down. 4. The smoked glass slide is again dipped into the wax solution using a fingertip and the excessive wax solution on the slide is absorbed on the filter paper and drain off. 5. Thus prepared smoked slide can be used for B.T.

The following experiments were carried out at rock method oyster field at Uduri, Dolsan-myon, Yeocheon-gun, Jeon-nam, Korea, in 1966. In this experiment, the settling rate of oyster at each exposure level and their growth rate were checked. 1. The settling rate of oyster spats was highest at 4 hour exposure level in the day-time during spring tide, and the growth rate became greater the lower stratum until 3 hours and 30 minutes exposure level. 2. Rocks applied at the place higher than 5 to 6 hour exposure level which amount 26 percents of applied rocks, were not utilized properly because the settling rate of spats and their growth rate were very bad. 3. For the future application of rocks for oyster culture, effort should be paid to instruct the oyster farmers to apply all rocks at proper exposure Ie el with bottom leveling and the rocks should be spaced properly for better barvest.

A phytoplankton study in the Korean waters has been commenced from 1964 as parts of the primary production studies in the Korean waters and the cruise for the cooperative studies of the Kuroshio from 1965 to 1968. Samples are taken by dipping 300-500 ml of sea water from the surface, and then fixed by adding neutralized formalin. The phytoplankton identification and cell counts are made on samples carefully after concentrated by decanting and centrifuging in the laboratory. This report deals with the surface phytoplankton obtained during the period of August 14-27, 1965 at twenty-three stations in the Korea Strait. Fifty nine species in seventeen genera of diatoms are detected from the samples collected at the stations. Among them seven species in five genera are considered to be purely neritic or cold water species and eight species in four genera are oceanic species of the Kuroshio. The highest phytoplankton standing crops are found in the sea area neighboring coastal waters of southern Korea, and the species distribution show anomalies in normally oceanic species being confined to neritic waters. There are distinct genera compositions of eastern, western and intermediate sea areas in the Kore Strait.
