  • Nielsen coincidence theory is concerned with the determinatin of a lower bound of the minimal number MC[f,g] of coincidence points for all maps in the homotopy class of a given map (f,g) : X $\to$ Y. The Nielsen Nielsen number $N_R(f,g)$ (similar to [9]) is introduced in [3], which is a lower bound for the number of coincidence points in the relative homotopy class of (f,g) and $N_R(f,g) \geq N(f,g)$.

  • The purpose of this study was to demonstrate immune-activities by heat therapy. To exam, furthermore, the immune effect is investigated from the healthy volunteer(male:15, female:15) by monitoring changes of immune substances such as complements(C1q, C3, and C4), a comparative study with warm water immersion($40.8{\pm}0.3^{\circ}C$) and infrared(250W) was carried out. The plasma analysis showed that the percentage of C1q, C3, and C4 was decreased in warm water immersion-stimulated group, but not in infrared-applied group, compared with control group from healthy volunteer. Therefore, these results suggest that the thermo-stimulation improved immune activity and inhibited complement-related inflammation through the warm water immersion-dependent classical pathway.

  • Paramyosin is a myofibrillar protein present in helminth parasites and plays multifunctional roles in host-parasite interactions. In this study, we identified the gene encoding paramyosin of Clonorchis sinensis (CsPmy) and characterized biochemical and immunological properties of its recombinant protein. CsPmy showed a high level of sequence identity with paramyosin from other helminth parasites. Recombinant CsPmy (rCsPmy) expressed in bacteria had an approximate molecular weight of 100 kDa and bound both human collagen and complement 9. The protein was constitutively expressed in various developmental stages of the parasite. Imunofluorescence analysis revealed that CsPmy was mainly localized in the tegument, subtegumental muscles, and the muscle layer surrounding the intestine of the parasite. The rCsPmy showed high levels of positive reactions (74.6%, 56/75) against sera from patients with clonorchiasis. Immunization of experimental rats with rCsPmy evoked high levels of IgG production. These results collectively suggest that CsPmy is a multifunctional protein that not only contributes to the muscle layer structure but also to non-muscular functions in host-parasite interactions. Successful induction of host IgG production also suggests that CsPmy can be applied as a diagnostic antigen and/or vaccine candidate for clonorchiasis.

  • Successful Six Sigma methodology involves continual success of projects, each incrementally moving the organization closer to its strategic goals of shareholder return and customer satisfaction. However, Six Sigma methodology has some disadvantages in long-term technical strategy parts, systematic technology management techniques and concrete idea creativity methodology. To complement these Six Sigma problems, Triz technique is considered. Triz focuses on solving such problems efficiently, effectively, and creatively. The purpose of this paper is to improve the temperature inspection method of a refrigerator through the DAGEV(Define-Analyze- Generate-Evaluate-Verify) cycle of Triz.

Performance Evaluation of Skewed Read-Head for Shingled Magnetic Recording (트랙을 겹쳐서 쓰는 자기기록 방식에서 리드헤드가 틀어진 경우의 성능 분석)

  • The shingled magnetic recording method has interference between adjacent tracks. Furthermore, when read-head reads the data along the track, the head can be skewed by some physical effects. In this paper, in order to solve this problem, we propose a two-dimensional equalizer that uses two heads. If the head is skewed, it is possible to complement the performance by positioning the two heads at the center of the current track.

  • An experiment was conducted to investigate the aerodynamic losses of high pressure steam turbine nozzle (526A) subjected to a large range of incident angles ($-34^{\circ}\;to\;26^{\circ}$) and exit Mach numbers (0.6 and 1.15). Measurements included downstream Pitot probe traverses, upstream total pressure, and end wall static pressures. Flow visualization techniques such as shadowgraph and color oil flow visualization were performed to complement the measured data. When the exit Mach number for nozzles increased from 0.9 to 1.1 the total pressure loss coefficient increased by a factor of 7 as compared to the total pressure losses measured at subsonic conditions ($M_2<0.9$). For the range of incidence tested, the effect of flow incidence on the total pressure losses is less pronounced. Based on the shadowgraphs taken during the experiment, it' s believed that the large increase in losses at transonic conditions is due to strong shock/ boundary layer interaction that may lead to flow separation on the blade suction surface.

  • Crane operation for transporting heavy loads inherently causes swinging motion at the loads due to crane's acceleration or deceleration. This motion not only lowers the handling safety but also slows down the handling process. To complement such a problem, Korea Atomic Energy Research Institute(KAERI) has designed several anti-swing controllers using open loop and closed loop approaches. They are namely a pre-programmed feedback controller and a fuzzy controller. These controllers are implemented on a 1-ton crane system at KAERI and their control performances are compared. Test operations show that the new controllers are superior to that of conventional cranes in terms of robustness to the disturbances and adaptation capability to the change of rope length.

  • In this paper, a new optical parallel binary arithmetic processor (OPBAP) capable of computing arbitrary n-bit look-ahead carry full-addition is proposed and implemented. The conventional Boolean algebra is considered to implement OPBAP by using two schemes of optical logic processor. One is space-variant optical logic gate processor (SVOLGP), the other is shadow-casting optical logic array processor (SCOLAP). SVOLGP can process logical AND and OR operations different in space simultaneously by using free-space interconnection logic filters, while SCOLAP can perform any possible 16 Boolean logic function by using spatial instruction-control filter. A dual-rail encoding method is adopted because the complement of an input is needed in arithmetic process. Experiment on OPBAP for an 8-bit look-ahead carry full addition is performed. The experimental results have shown that the proposed OPBAP has a capability of optical look-ahead carry full-addition with high computing speed regardless of the data length.

  • A nutrition survey of 99 children, 3 to 6 years old, in the day care center, situated in Kamman-dong of Pusan, as the location of one of the socioeconomically vulnerable groups, was undertaken between July 1 and 14, 1992, to investigate dietary intake and nutritional status. The results are summarized as follows. Hematocrit value was 38.9%. Mean content of serum iron was 53.5$\mu\textrm{g}$/100$m\ell$ and 17.2% of the subjects were below the borderline of anemia. Mean contents of serum total protein, serum albumin and serum complement $C_3$were at an acceptable level, But, 27% of the subjects were below the borderline of protein deficiency, Energy intake of the children was 68.6~87.5% of the RDAs and mean protein intake was 94.1~114.1% of the recommendation. Low intake of Ca, Fe, vitamin A, B$_1$, B$_2$, C, niarin were also found. The survey found 10% of the subjects skipped a meal once a day, The children intake 3.3~5.5 kinds of the food every meal. The following percentages of the children intake below 75% of the RDAs ; 68% of the children for Fe, 60.2% for vitamin C, 58.3% for niacin, 58.2% for Ca, 46.6% for energy, 37.9% of vitamin B$_2$, 37.8% of vitamin B$_1$.
