This study evaluated the quality characteristics of crust derived from dry-aged Holstein and Hanwoo loins and their effects on food as additives. With respect to physicochemical properties, we examined the proximate composition, pH value, salinity, color, water and fat absorption, emulsifying capacity, and swelling yield. The protein and ash contents in the Holstein crust were significantly higher than those in the Hanwoo crust (p < 0.0001). The fat content in the Hanwoo crust was significantly higher than that in the Holstein crust (p < 0.01). The salinity, lightness, and yellowness of the Hanwoo crust were significantly lower than those of the Holstein crust (p < 0.001). Furthermore, the pH value and emulsifying capacity of the Hanwoo crust were significantly higher than those of the Holstein crust (p < 0.001). The fat absorption of the Holstein crust was significantly higher than that of the Hanwoo crust (p < 0.001). The swelling yield of the Holstein crust was significantly higher than that of the Hanwoo crust at pH 3 and 4 (p < 0.001), whereas the swelling yield of the Hanwoo crust was significantly higher than that of the Holstein crust at pH 7 (p < 0.001). Principal component analysis of dry-aged Hanwoo, Holstein, and non-aged Holstein showed different flavor patterns for each sample. Finally, the results showed that the crusts derived from dry-aged Hanwoo and Holstein loins were suitable flavor enhancers.

To examine the effects of an educational program with a purpose of reducing symptoms and ailments of women's premenstrual syndrome on the basis of the Self-care theory of Orem, a stimulation was carried out by using pre-and post-design of non-equity control group after choosing both an experimental group of 62 persons and a control group of 62 persons among 497 industrial women. This study was conducted from June 20, 1996 to September 30, 1996. Meantime, an education was provided for the experimental group of 62 persons for 8 weeks but no education for the control group of 62 persons. Study matters are general and obstetric characteristics, knowledge and self-care behavior and premenstrual syndrome from questionnaires with 497 industrial women, pre and post questionnaires with the control group of 62 persons and the questionnaires collected before and after providing an education for the experimental group of 62 persons, these matters were used as research data for this study and analyzed by means of the SAS program. As a result, it was shown that the scores of 497 industrial women's knowledge by age were the highest 26.36 for 20 to 29 year old women, then 25.58 for 30 to 39 year old women and 25.74 for less 19 year old women. The performance scores of their self-care behavior by age were the highest 39.17 for 30 to 39 year old women, 35.72 for 20 to 29 year old women and 32.85 for less 19 year old women, which means that the older the women are, the higher the performance degree is(p<0.01). And the scores of their premenstrual syndrome by age were 2.80 for less 19 year old women, 2.18 for 20 to 29 year old women and 2.00 for 30 to 39 year old women. Women in their teens and twenties showed more serious symptoms and ailments of premenstrual syndrome than women in their thirties(p<0.01). For the experimental group of 62 persons who received the educational program, both the knowledge of premenstrual syndrome and the degree of self-care behavior were remarkably improved(p<0.01), respectively and the symptoms and ailments of premenstrual syndrome were also remarkably reduced(p<0.01), while the control group showed no change in the knowledge, self-care behavior, and symptoms and ailments of premenstrual syndrome. The above results demonstrated that educational program based on the Self-care theory of Orem is an effective intervention to reduce the symptoms and ailments of premenstrual syndrome. The effects of the study can be generalized by extending the application in which various age groups and professional and social environments are considered together with a research to evaluate the long-term effects of this educational program. Accordingly, it is expected that it can possible not only to provide help for the women by actually applying the program to practical areas for improvement of women's health but also to suggest plans to activate it as one of health education areas.

Purpose: Tumor recurrence is the principal cause of poor outcomes in remnant gastric cancer (RGC) after resection. We sought to elucidate the recurrent patterns according to tumor locations in RGC. Materials and Methods: Data were collected from the Shanghai Cancer Center between January 2006 and December 2020. A total of 129 patients with RGC were included in this study, of whom 62 had carcinomas at the anastomotic site (group A) and 67 at the non-anastomotic site (group N). The clinicopathological characteristics, surgical results, recurrent diseases, and survival were investigated according to tumor location. Results: The time interval from the previous gastrectomy to the current diagnosis was 32.0±13.0 and 21.0±13.4 years in groups A and N, respectively. The previous disease was benign in 51/62 cases (82.3%) in group A and 37/67 cases (55.2%) in group N (P=0.002). Thirty-three patients had documented sites of tumor recurrence through imaging or pathological examinations. The median time to recurrence was 11.0 months (range, 1.0-35.1 months). Peritoneal recurrence occurred in 11.3% (7/62) of the patients in group A versus 1.5% (1/67) of the patients in group N (P=0.006). Hepatic recurrence occurred in 3.2% (2/62) of the patients in group A versus 13.4% (9/67) of the patients in group N (P=0.038). Patients in group A had significantly better overall survival than those in group N (P=0.046). Conclusions: The tumor location of RGC is an essential factor for predicting recurrence patterns and overall survival. When selecting an optimal postoperative follow-up program for RGC, physicians should consider recurrent features according to the tumor location.

For $1 < p \leq 2$ it is shown that a certain sequence of functions converges to -1 in $L^{p-\varepsilon}(0, 1)$ for any small $\varepsilon > 0$ if and only if the Riemann zeta function satisfies $\zeta(s) \neq 0$ for $\sigma = Re s > 1/p$.

We demonstrate a $2.1\;{\times}\;1.0\;{\times}\;0.1cm^3$ sized compact transmitter using LTCC System-in-Package (SiP) technology for 60GHz-band wireless communication applications. For low-attenuation characteristics and resonance suppression of the SiP, we have proposed and demonstrated a coplanar double wire-bond transition and novel CPW-to-stripline transition integrating air-cavities as well as novel air-cavities embedded CPW line. The fabricated transmitter achieves an output of 13dBm at a RF frequency of 62GHz, an IF frequency of 2.4GHz, and a LO frequency of 59.6GHz. The up-conversion gain is 11dB, while the LO signal is suppressed with the image rejection mixer below -21.4dBc, and the image and spurious signals are also suppressed below -31dBc.

To study the corrosion fatigue begavior of T.M.C.P. steel, the rotary bending fatigue test with the change of concentration of NaCl solution was carried out. Fatigue life in the corrosion environment is decreased markedly in comparision with that in the air. Fatigue limit in the air was about 225 MPa. In case of 3.5% NaCl solution fatigue life could be expressed as .sigma./sub f/=10,392 * (N/sub f/)/sup -o.2923 . According to the paris's rule, crack growth rates could be expressed as da/dN=2.62.*10/sup -7/ .DELTA. K/sup 1.09/(3.5% NaCl solution), da/dN=1.95 *10/sup -7 .DELTA. K/sup 1.05/(1% NaCl solution), da/dN=2.62 * 10/sup -7/.DELTA./sup 0.72/(0.01% NaCl solution) with da/dN expressed in mm/cycle and .DELTA.K in MPa.GAMMA.m. The crack growth rate in the corrosion environment was highest under 3.5% NaCl solution.
