Purpose: Social support is essential for postpartum well-being, but little is known about the postpnatal social support preferred by primiparous women. This study aimed to comprehensively understand and describe the meaning of postnatal social support experience in primiparous women. Methods: The participants were seven primiparous women who were within 1 year after childbirth, recruited through purposive and snowball sampling from an online parenting community. The data were collected through in-depth interviews from November 14 to 28, 2022. Participants were interviewed face-to-face or via phone or online platform, according to their choice. Colaizzi's phenomenological qualitative research method was applied to analyze the meaning of the participants' experience. Results: Five theme clusters and fourteen themes were identified from the data. The five theme clusters are as follows: (1) Shortcomings of the childbirth and postpartum care system I learned through my experience; (2) Government policies focusing on childbirth and child-rearing rather than postpartum recovery; (3) Driving force of postpartum recovery: Shared childbirth process; (4) Childcare on my own; and (5) Conflicted between being a stay-at-home mom and a working mom under inadequate maternity protection policies. Conclusion: Despite postpartum support from the government that was perceived as inadequate, first-time mothers regained confidence and motivation for parenting with the help of family, peers, and social networks. First-time mothers need support from professionals and reliable online communities for postpartum recovery and parenting.

In recent years, with the advancement of IT technology, we expect data size of the world to increase 10 times in 2025. The rapid development of this Internet technology leads to the downsizing of the server system of the data center which manages and operates the data, the capacity of the storage medium, and the power consumption of the data center. In this paper, we propose an energy conservation policy and analyze it in real time by analyzing the power consumption pattern of the server system of the data center. The proposed system can monitor and analyze the power consumption pattern of the individual server system in the data center, and it can be expected that about 10% of the total power consumption of the data center will be saved by efficiently managing the actual operation time of the server system.

최근 들어 리얼 버라이어티가 TV 프로그램의 주를 이루면서 인체 기관에 자극을 주는 다양한 음식을 먹는 것이 게임에 등장하고 있다. 특히, 까나리액젓이나 레몬 빨리 씹어 먹기 등 인체에 자극을 주는 벌칙 게임들이 펼쳐지고 있다. 레몬은 모든 독의 해독제라고 할 만큼 우리 몸에 이로운 점이 많으나 과하거나 급할 경우 오히려 병이 될 수도 있다. 따라서 본 논문에서는 대체 및 예방의학에 이용되는 중요한 요소 중 하나인 식이요법에 대한 효능을 입증하기 위한 방법으로 음성신호 분석 기술을 적용하여 레몬 섭취에 따른 성대 진동의 변화를 측정하고 이에 대한 분석을 통해 레몬과 음성과의 관계를 규명하는 연구를 수행하고자 한다.

인간의 본능적인 욕구 중 생리적 욕구는 생존을 위해서 불가결한 것 중 하나이며 이러한 생리적 요구엔 성욕이 포함되어 있다. 성욕은 외부자극으로 인하여 욕구가 충동되며 도파민과 테스토스테론의 호르몬 분비가 일어나 성적 충동을 증가시켜 신체변화에 영향을 미친다. 따라서 본 논문에서는 성욕을 자극하여 성적 충동이 증가되었을 때 목소리의 변화를 분석하는 연구를 수행하였다. 이를 위해 성적 충동이 증가되기 전과 후의 음성을 수집하고 성대 관련 음성분석 요소인 Pitch, Intensity 기술을 적용하여 변화된 음성의 특징을 추출하였다.

Cu-Zn-Al catalysts were prepared via co-precipitation method for low-temperature water-gas shift (LT-WGS) reaction under practical reaction condition. Aging time was systematically changed to find optimum point for LT-WGS under practical condition. The Cu-Zn-Al catalyst aged for 72 hours showed the highest CO conversion within low-temperature range as well as very stable catalytic activity for 200 hours despite the practical reaction condition.

유비쿼터스 시대를 맞아 많은 USN 개발이 있어왔다. 이 센서 데이터를 전세계적으로 공유하기 위한 다양한 시도들이 있어왔다. 본 논문에서는 근래들어 개발된, 서버없이 구성 가능한 구조화된 P2P 기술을 기반으로하여, 인터넷 상에서 센서데이터를 공유하기 위한 방식을 제안하고 이를 KOREN에서 구축하였다. 구조화된 P2P중의 하나인 Patry에 기반하여, Scribe 기반의 실시간 센서 데이터와 Past기반의 과거 데이터에 대한 모니터링이 가능하도록 하였고, 센서 데이터를 찾기위한 모듈을 제안하였다.

This study was carried out to investigate effect of irradiation doses on quality of vacuum-packed dry-cured ham during storage. Dry-cured pork slices were vacuum-packaged in nylon/ polyethylene bags. Vacuum-packed dry curd pork was stored at $10{^{\circ}C}$ for 12 weeks after irradiation (0 kGy, 2.5 kGy, 5 kGy, 7.5 kGy and 10 kGy) and physicochemical properties of dry curd porks, such as meat color surface, thiobarbituric aicd reactive substances, volatile basic nitrogen, pH, microbial (total plate count, Lactobacillus) and sensory properties (color, flavor, overall acceptability) were investigated. Irradiation treatment decreased a*-value, TPC and Lactobacillus. Irradiation dose significantly (p<0.05) increased irradiation flavor and TBA value. However, irradiation dose decreased redness and sensory color in dry-cured ham. The quality of dry-cured ham was affected by the irradiation dose. The results suggested that dry-cured ham irradiated at 5 kGy dose may show optimum quality characteristics of the products as well as microbial safety.

A total of one hundred twenty pigs were used to investigate effects of silage feeding on pork quality among three breeds (Gagoshima Berkshire, American Berkshire, $LY{\times}\;D$). Pigs weighing about 70 kg of body weight were randomly alloted into three breeds [B (Gagoshima Berkshire), D $(LY{\times}\;D)$, A (American Berkshire) by two dietary treatment [C (commercial diet feed) and T (commercial diet with 80% silage)]. All pigs were fed 67 days of period and then slaughtered to examine meat characteristics. A chemical compositions and physico-chemical characteristics were measured in pork loin. The crude protein content was higher in pig fed diets containing silage than that of the control group. $L^*$ of meat color, appearance, meat color, marbling score and overall acceptability in sensory score of fresh meat were higher in the pigs fed silage (T) than those fed commercial diet (C). In fatty acid compositions of loin, stearic acid and oleic acid were lower in T than C, whereas arachidonic acid, EFA (essential fatty acid) and EFA/UFA (unsaturated fatty acid) were higher in T.

The objective of this study was to provide basic information for selecting the right timing and the right place of erosion control of stream on Gyeongsangnam-do. In order to achieve this objective, a total of 526 erosion control dams and 230 mountains stream conservation facilities on the constructed places and construction planned places for the erosion control were investigated on site, forest physiognomy, and hydrologic conditions. The erosion control dams and mountain stream conservation facilities were mostly constructed in the area, which has the sedimentary rock, 200-400m of altitude, a slope of 21~30°, and II of landslide hazard map. Among the forest environmental factors, it was only similar to the construction frequency in the areas that have small diameter class, III age class. Also, we investigated the hydrological environmental factors that determine the size and numbers of erosion control dam. The places constructed to the highest frequency were below 50ha in the area, 2.1~4.0km/㎢ of drainage density, longitudinal water system, 61~90mm of maximum precipitation per hour, and 201~300mm of day maximum precipitation. As the results, the sites and floodgate conditions between the constructed places and stream conservation facilities for the erosion control showed to be very similar. Therefore, these results indicate that the erosion control of the stream of the areas, which have the disruption of mountain peaks and the high erosion risk areas, should be used on both the erosion control dam and stream conservation facilities.
