This research is about effects which frontal-flat cameras have on narrative films. This kind of confined camera angles make the audience have a sense of tension which is barely defined logically. I think the tension comes from aleatorism. The paper is a research on how aleatorism is working on what kind of value, and what kind of effects it has on narrative films. Russian Formalism had argued they had to meet aesthetic values by totally excluding narratives. It can be said that this was a practice for Brecht's estrangement that a sensitive arousal prohibits the audience immersing into excessive empathy and then make them have a reflective thought. But occasionally, optical arousals in narrative films induce deeper immersion into contemplation rather than reflective thought. I intend to find cases regarding this textualising Front-flat camera angles in narrative films and analysing their contents. To do this, I suggest a more specified definition of 'aleatorism'. Because the concept of the aleatorism is different between an aspect of static image like paintings or photographs and narrative contents like cinema. It is divided into approach through form and approach through content. And I also suggest an operative definition about 'Frontal-flat camera angle' with a several confinements because its formal definition is very flexible depending on audience. The case analysis will be done with a form of discourse discerning two aspects of form and content. Conclusively, Frontal-flat camera angle in narrative film is basically have an effect of attention by optical stimuli. But it cannot be said that this always means deterioration of narrative value. Depending on causality of episodes in the whole story, aleatorism which Frontal-flat camera angle has can support immersed contemplation regarding following narrative rather than reflective thought regarding amusing aesthetics.

We examined the contents of amino acids to provide the basic data for the utilization of white panicled rice (Oryza sativa L., WPR) cultured in reclaimed paddy field of Bigumdo of Korea in 2011. WPR used in this study were collected in 1000 ha of reclaimed paddy field of Bigumdo. Crude protein contents of whole rice have the highest in leaf blade, followed by whole grain, leaf sheath and stem. The contents of total amino acids showed the highest trend in region received the most severe damage, but the lowest trend in region of normal growth. The content of glutamic acid was the highest among amino acids in leaf blade, whole grain, leaf sheath and stem collected in all regions, but the content of methionine was the lowest. Therefore, the contents of amino acids showed a similar level between the region occurred WPR and the region of normal growth. Further research on the nutritional aspects of forage must be performed because nutritive values of WPR were influenced by the degree of damage of WPR.

The buffer is a key component of the engineered barrier system in a high-level radioactive waste (HLW) repository. The present study reviewed the requirements and functional criteria of the buffer reported in literature, and also based on the results, proposed an approach to establish a buffer concept which is applicable to an HLW repository in Korea. The hydraulic conductivity, radionuclide-retarding capacity (equilibrium distribution coefficient and diffusion coefficient), swelling pressure, thermal conductivity, mechanical properties, organic carbon content, and illitization rate were considered as major technical parameters for the functional criteria of the buffer. Domestic bentonite (Ca-bentonite) and, as an alternative, MX-80 (Na-bentonite) were proposed for the buffer of an HLW repository in Korea. The technical specifications for those proposed bentonites were set to parameter values that conservatively satisfy Korea's functional criteria for the Ca-bentonite and Swedish criteria for the Na-bentonite. The thickness of the buffer was determined by evaluating the means of shear behavior, radionuclide release, and heat conduction, which resulted in the proper buffer thickness of 0.25 to 0.5 m. However, the final thickness of the buffer should be determined by considering coupled thermal-hydraulic-mechanical evaluation and economics and engineering aspects as well.

This experiment was carried out to investigate the difference of seed vigor according to seed size, and the physiological aspects and physico-chemical phenomena related with seed vigor in soybean cultivars. Portion of seed coat and radicle to entire seed was much higher in cultivars with small seed than with large. Seed coat rate ranged 7.9% to 9.9%, and radicle 2.5% to 3.3% in small seed group, Whereas in large seed, seed coat rate did 5.5-6.4% and radicle, 1.5 to 2.1%. After accelerated aging treatment, there are significant difference in germination ability between seed size. The germination rate after aging ranged 47 to 80% in cultivars with small seed, but in large seed, only 14 to 24%. After seed was carried out dehydration in incubator at 25 after soaking for 6 hours, the moisture content of seed in drying for 12 hour was 25.5% in small seed, while it was 51% in large seed. Electrical conductivity, leaching soluble nitrogen and sugar content were higher in large seed cultivars. Besides, cotyledon damage after soaking was occurred frequently in large seed cultivars, and seed vigor within same cultivars was higher in small seed than large.

The purpose of this study was to develop and apply a framework for progression in the professional development and learning of secondary science teachers' teaching practice. The progression in the professional development was modified Pilhee Woo's framework(2010), and in the learning was developed by the researchers. The former included 6 elements and 36 aspects. The progression of each aspect was composed of five level criteria. The content validity is 96.4% and the reliability is .96. The latter was composed of another five level criteria. The content validity is 96.0% and the reliability is .95. Internet-online test and the questionnaire were administered to 203 secondary science teachers who were selected by convenience sampling. The mean level of the progression in the professional development and learning were 2.21 and 2.95. ANOVA, t-test and correlation analysis were conducted to compare differences by the characteristics of teachers. The level of the progression in the professional development and learning was significant difference according to almost all of teachers' characteristics. The level of the progression in the professional development was significantly correlated with the level of the progression in the learning.

This study investigated sex determination through serum steroid hormone level and compared hematological characteristics of one-year old cultured eels, Anguilla japonica. Four different groups were divided with total length at 40∼45, 45∼50, 50∼55, and 55∼60 cm. Males dominated eels of 40∼50 cm in total length group, while females dominated eels of more than 50 cm. All females and males were immature. Hematocrit levels of males (total length: 40∼50 cm) were higher than those of females (total length: 50∼60 cm). Hemoglobin content also differed between males and females. Glutamate oxaloacetate transaminase (GOT) levels of 40∼45 cm males tended to be higher (157$\pm$3.46 IU/L) than that of other sized males, but there were no significant differences between groups (P<0.05). The highest GOT levels were found in of 55∼60 cm females (148$\pm$3.46 IU/L) compared with that of other female groups (P<0.05). Glutamate pyruvate transaminase (GPT) levels of males and females in the 55∼60 cm size range was significantly higher thanothers (P<0.05). The result of this study indicated steroid hormone content of males and females were very low, but testosterone (T) and estradiol-17$\beta$, (E2) contents of females were higher than those of males. For further research of sex determination in cultured eels, it needs to investigate in more defined body length.

This study was done for the preparation of macromolecular material with UV-blocking features by adding the benzophenone group that is commonly used as a UV-absorbent and $TiO_2$ which is known to be a very stable material in chemical and physical aspects. Also, we compared the level of UV absorbency of the polymer produced from polymerization with previous materials and measured basic properties such as water content, refractive index and optical transmittance of produced contact lenses. The results of the measurement showed that the refractive index and water content of the contact lens with added UV-absorbent was 1.430~1.440 and 35.0~45.0% respectively, which was similar to that of previous contact lenses. Also, for optical transmittances of each wave length, contact lenses without the UV-absorbent was 89%, 88% and 89% respectively for UV-A, UV-B and visible light, indicating that the UV transmittance is very high though contrary with cases of contact lenses with added 2-hydroxy-4-methoxy-benzophenone and 2,4-dihydroxy-benzophenone which showed transmittances of 0% and 6% respectively for UV-A and UV-B showing a UV-blocking effect. Meanwhile, contact lenses with added $TiO_2$ showed transmittance of 6% and 51% respectively for UV-A and UV-B also showing a UV-blocking effect. The visible transmittance was 77~89% showing that it satisfies the visible transmittance required for ophthalmological materials.

Higher plants can be categorized as C3, C4 or CAM according to their photosynthetic pathways, and some succulent plants are known to shift their patterns of photosynthesis from C3 to CAM in response to environmental stresses such as salt treatment or water deficiency. To investigate fundamental photosynthetic patterns and the induction of pattern shifts (C3, CAM, C3-CAM etc.) as a result of environmental stresses, we measured the water content, diurnal changes in pH, net $CO_2$ exchange, transpiration rate, total ionic contents, and osmolality of Kalancoe daigremontiana, Sedum kamschaticum and Sedum sarmentosum which belong to Crassulaceae known as representative CAM plant, after 10 days of drought treatment. S. kamschaticum and S. sarmentosum did not show a significant difference in diurnal pH variation in the treatment and control conditions. However, the pH of drought-treated Kalancoe was low at night and high in the daytime, with a pH value between 4 and 5. Typical CAM plants display a net $CO_2$ exchange that increases at night and decreases in the daytime. Kalancoe displayed the predicted pattern. However, S. kamschaticum and S. sarmentosum showed a photosynthetic pattern more typical of C3 plants, and did not show changes in photosynthetic pattern under drought stress. Kalancoe also showed a transpiration rate typical for CAM pho-tosynthesis, whereas the transpiration rates of S. kamschaticum and S. sarmentosum were in the typical range for C3 photosynthesis. Kalancoe had high total ionic contents during the night, which decreased somewhat during the daytime, whereas S. kamschaticum and S. sarmentosum displayed the opposite pattern. This result is similar to the diurnal patterns of changes in pH in the three plant species, which suggests a relationship between pH and ionic contents. S. sarmentosum showed lower osmolality under drought stress than in the control condition, whereas the osmolality of Kalancoe and S. kamschaticum did not differ between conditions. S. sarmentosum may have maintained internal water content by lowering its osmolality and raising its total ionic contents. In conclusion, Kalancoe displayed the characteristic responses of a typical CAM plant, whereas S. kamschaticum and S. sarmentosum displayed aspects of the C3 photosynthetic pattern under drought conditions. These results suggest that S. kamschaticum and S. sarmentosum (Crassulacea) in Korea overcome drought stress by increasing solute and ionic contents internally rather than changing their photosynthetic pattern from C3 to CAM under drought stress.

Red pepper powder (Capsicum annuum L.) is one of the most important ingredients for making kimchi. Various aspects of the quality of the red pepper powders (RPP) produced in Korea depending on the varieties and producing districts were compared. The evaluated intrinsic elements were vitamin C, carotenoid, capsaicinoid and free sugar contents and the extrinsic element was ASTA (American Spice Trade Association) colors. The vitamin C content was the highest in Johong (230 mg%) RPP among the varieties and Youngyang (263 mg%) RPP among the producing districts. Myungpum RPP that contains high level of carotenoids showed increased level of ASTA color, it exhibited positive relationship between carotenoid contents and ASTA color. Capsaicinoid level in RPP was the highest in var. Chungyang (126.1 mg%) that was usually used soup and pungent cook. Free sugar contents which is related to sweetness were the highest in Youngyang RPP Youngyang RPP that preferentially used in the preparation of kimchi showed the highest levels in vitamin C, carotenoid, ASTA color, and free sugar contents, but the contents of capsaicinoid was the lowest.

The purpose of this study was to investigate how early retirees spent their days and how daily life was experienced. In order to cover as many aspects as possible of the subject, this study examined sources of life satisfaction/dissatisfaction. Data were drawn from in-depth interviews in which 101 early retirees residing in Seoul. The Majority of early retirees in this study were at least somewhat dissatisfied with their daily life. Content analysis of reasons for life satisfaction/dissatisfaction revealed that the sources were categorized into 6 categories and 66 specific sources. Analysis of sources of life satisfaction revealed that early retirees mentioned most frequently as their sources of life satisfaction in this order: subjective emotions, family relations, stability of economy, positive attitude on retirement. Analysis of sources of life dissatisfaction revealed that life dissatisfaction was intimately connected with the loss of work role, family, unstability of economy, and ill preparation for retirement. Implications for macro and micro alternatives to support early retirees were provided.
