Newly manufactured compound fertilizers for chestnut trees developed by Chosun Fertilizer Inc. were tested to evaluate their effectiveness. An experiment was carried out in chestnut farm with 4 years old Eungi Var. from 1981 to 1982. The results obtained are as follows: 1. The growth of chestnut trees was generally good in plots of compound fertilizer contained boron (B C F). 2. The number of ripened strobiles was significantly increased by reducing the ratio of dropped strobiles in plot of B C F. 3. The yield of chestnut by B C F was markedly increased, 6 times more than that of compound fertilizer without boron. 4. Boron content in soil and plant by application of B C F was relatively high, resulting in high production of chestnut. 5. B C F was effective in chestnut orchard to increase nut production markedly.

Because cancer is not curable, patients who suffer from the cancer disease may have physical, psychological and spiritual problems for the rest of their lives. Especially, when cancer patients do not have the meaning in their lives, they will experience spiritual distress seriously. This study was conducted to provide a basis for nursing intervention strategies to minimize the cancer patients' spiritual distress and understand the relationship between the meaning of life and the spiritual distress in cancer patients. The samples were composed of 62 cancer patients who were inpatients or outpatients of three university hospital and one general hospital in Seoul. Data collection was carried out from January 10,1998 to May 30, 1998. Data were analyzed using a SAS program for descriptive statistic, Pearson correlation, t-test, ANOVA, LSD test and linear regression. The results were as follows; 1. The scores on the meaning of life scale ranged from 20 to 140 with a mean of 94. 16(Standard error: 2.79). 2. The scores on the spiritual distress scale ranged from 13 to 91 with a mean of 62. 29(Standard error: 1.38). 3. There were significant correlations between the meaning of life and the spiritual distress(r=.53. p=.00). 4. The linear regression analysis showed that the meaning of life explained 29% of the spiritual distress. 5. In the degree of the meaning of life and the spiritual distress according to the general characteristics, the level of the meaning of life in cancer patients were different by age(F=3. 42, p=.03), marriage status(F=6.06, p=.00), religion(F=4.21, p=.01), thought about treatment of cancer(F=3.76, p=.04). And the level of the spiritual distress in cancer patients were different by religion(F=7.56, p=.00). In conclusion, the meaning of life was identified as important variable that was contributed to reduce the spiritual distress in cancer patients.

Since cancer is not easily curable, patients who suffer from cancer may have physical, psychological and spiritual problems for the rest of their lives. Especially when cancer patients do not have much to live for and are placing a burden on their family they will experience more suffering emotionally as much as physically. This study was conducted to provide a basis of data for nursing intervention strategies to minimize a cancer patient`s suffering and to understand the relationship between suffering, burden and the meaning of life in cancer patients. The samples were composed of 160 cancer patients who were inpatients or outpatients of two university hospitals and two general hospitals in Seoul. Data collection were carried out from January, 25, 1999 to February, 26, 1999. The data were analyzed using a SAS program for descriptive statistics, pearson correlations, ANOVA, and Duncan tests. The results were as follows; 1. The scores on the two suffering scale ranged from 132 to 40 with a mean of 87.3(SD 17.5). The mean scores on the burden scale is 28.9(SD 6.9) and the score of the meaning of life ranged from 35 to 51 with a mean of 95.6(SD 18.4). 2. There were significant correlations between the amount of suffering and the magnitude of burden (r=.74, p=.00), the suffering and the meaning of life (r=-.59, p=.00) and the burden and meaning of life (r=-.61, p=.00). 3. In the degree of the suffering, the burden and the meaning of life were two very strong factors, the level of the suffering in cancer patients by age (F=2.64, p=.03) and education level (F=4.16, p=.00). The level of the burden in cancer patients differed by education level (F=4.70, p=.00) and type of cancer (F=2.97, p= .03). Also the level of the meaning of life in cancer patients was different by education level (F=3.55, p=.02). In conclusion, the burden and the meaning of life was identified as important variable that is contributed to reduce the suffering of cancer patients.

We designed the Intermediate Frequency(IF) distributor for multi beam backend system and manufactured Voltage to Frequency Converter(VFC) to measure the multi-beam receiver performance. Multi beam receiver has 15 channel receivers and can get 15 spectrums at once. The multi beam receiver has more observation efficiency than single beam receiver. We manufactured the 15 IF distributors to distribute IF signal for Autocorrelation spectrometer that is radio signal processor. Also, we manufactured the VF Converter to test the performance measurement of receiver for Korea VLBI Network(KVN) system which is under-construct in Seoul, Ulsan and Jeju. As a result of performance measurement, we could obtain linearity of 99.4% on the input power vs output frequency and measured the operating range of input frequency.

Tripterygium wilfordii Hook.f. (Celastraceae), collected from Phia Oac-Phia Den National Park of Vietnam, is reported here as a new generic and species record for the flora of Vietnam. The genus Tripterygium differs from other genera of Celastraceae by its samara fruits, which become three-winged at maturity, and a scandent shrub. Taxonomic notes, descriptions, line drawing and photographs are provided, together with short notes on the distribution, ecology and phenology of Tripterygium wilfordii Hook.f. (Celastraceae).

Maturity and spawning of the pointhead flounder, Hippoglossoides pinetorum were investigated on the basis of samples collected in the coastal waters off Gangwon-do, East Sea from January 2012 to December 2013. The average total length of H. pinetorum was 25.0 cm and 21.9 cm for females and males, respectively. The spawning period was from May to July according to monthly changes gonadosomatic index (GSI) and maturity stages. The spawning period in Gangwon-do was delayed relatively to that in Gyeongbuk-do. The mature egg diameter ranged between $300-700{\mu}m$. The relationship between TL and fecundity (F) was F = 63.574 TL - 1471.3 ($R^2=0.7603$), that is, the larger total length, the more fecundity H. pinetorum had. We estimated that the TLs at 50% group maturity were 25.6 cm for females and 19.9 cm for males. The spawning ecology by sea area should be considered efficient resource management for H. pinetorum. Furthermore, it is necessary to study more on the relationships among growth, maturity and water temperature variations in the East Sea.

We establish a common n-tupled fixed point theorem for hybrid pair of mappings under new contractive condition. It is to be noted that to find n-tupled coincidence point, we do not use the condition of continuity of any mapping involved. An example supporting to our result has also been cited. We improve, extend and generalize several known results.

The brown algal family Chordariaceae sensu lato is a focus of taxonomy because recent studies suggest a broad concept of the family, including genera formerly classified in the Dictyosiphonales. Using morphology, plastid rbcL and nrDNA ITS sequences, we evaluated relationships of the monotyic genus Soranthera (S. ulvoidea), which has been classified in the Punctariaceae. The species occurs in Bering Sea and Aleutian Islands, Alaska to Baja California. Thalli are globose to lobed, hollow, 3-5 cm in diameter, and covered with evenly distributed sori. However, two forms within the species are recognized: f. ulvoidea for globose forms and f. difformis for lobed forms. Plastid rbcL and nuclear ITS region sequences were newly determined in samples of S. ulvoidea from the Pacific coast of the North America. We found little variations in the ITS sequences among samples of S. ulvoidea from five different locations and in the rbcL region from two different locations. These results do not support previous classification of f. ulvoidea and f. difformis within the species. All analyses of our rbcL sequence dataset show that Soranthera was placed in the Chordariaceae s.l., but more related to Botrytella than Punctaria and Asperococcus.

$TiO_2$ thin films are fabricated using R.F.sputtering method. $TiO_2$ thin films are coated on $Al_2O_3$ substrate printed IDE(interdigitated electrode). Impedance of thin films decreases according to increase relative humidity and it increases according to decrease measuring frequency. When substrate temperature is room temperature, impedance of thin films is from 45.68[MHz] to 37.76[MHz] within the limits from 30[%RH] to 75[%RH] at 1[kHz]. Whereas when substrate temperature is 100[$^{\circ}C$], impedance of thin films is from 692[kHz] to 539[kHz] within the limits from 30[%RH] to 75[%RH] at 1[kHz]. Impedance variation of thin films is bigger in low frequency regions than in high frequency regions. When substrate temperature is 100[$^{\circ}C$], impedance of thin films is lower than that of room temperature.

Since the early 2000s, there has been a continued interest in lie detection using functional magnetic resonance imaging (fMRI) in neuroscience and forensic sciences, as well as in newly emerging fields including neuroethics and neurolaw. Related fMRI studies have revealed converging evidence that brain regions including the prefrontal cortex, anterior cingulate cortex, parietal cortex, and anterior insula are associated with deceptive behavior. However, fMRI-based lie detection has thus far not been generally accepted as evidence in court, as methodological shortcomings, generalizability issues, and ethical and legal concerns are yet to be resolved. In the present review, we aim to illustrate these achievements and limitations of fMRI-based lie detection.
